About this board game
Potion Explosion is a board game for 2 to 4 players with a playing time of about 45 minutes, first released in 2015. Designed by Lorenzo Silva, Andrea Crespi, and Stefano Castelli, it places players in the final exams of the Potions class.
The rules are simple to understand but demand more than speed. On your turn, take an ingredient marble from the dispenser and watch the others fall. When marbles of the same color connect, they explode, allowing you to take those marbles as well.
Use the ingredients you collect to complete your potions. Once a potion is ready, drink it to unleash its magical power. The marbles you gather and the potions you finish are central to your progress through the exam.
- Take an ingredient marble from the dispenser.
- Collect connected marbles of the same color when they explode.
- Complete potions with the ingredients you gather.
- Drink finished potions to unleash their magical powers.
Although being quick matters, it is not enough to earn the Student of the Year award. In Potion Explosion, you must also brew the most valuable potions to win.
With its colorful marble dispenser, ingredient explosions, and magical potion powers, Potion Explosion presents a lively competition for 2 to 4 students. Whether you are seeking the highest-value brews or enjoying the spectacle of matching marbles falling into place, the final exam awaits.
Board Game Rules for
Potion Explosion
Welcome to the Potions Lab
Dear students,
It’s that time of the year.
Your last year at the Horribilorum Sorcery Academy for Witty Witches and Wizards is almost over, and it’s time for the final exams!
As always, the rules are the same: Take the Ingredients from the Dispenser in the Potions Lab to complete your Potions. Keep in mind that the explosions you may trigger can be useful! The use of Potions you brew during this exam is not only allowed, but encouraged! Use them wisely to do a quicker and better job, and it will prove your worth as a soon-to-be witch or wizard.
When enough Skill Tokens have been awarded, the exam will end. Remember, though, that in order to win the Student of the Year Award, you’ll need to be the one who brewed the most difficult (and valuable) potions!
Good luck!

Components
(Presentatio componentibus)

- 1 Plastic Dispenser (with a drawer to store marbles between games)
- 80 Ingredient marbles (in 4 colors, 20 marbles of each color; a small bag with some replacement marbles is included, in case you lose some)
- 64 Potion tiles of 8 kinds (Potions of the same kind have the same power icon)
- 15 Skill tokens
- 21 Little Help tokens
- 1 First Player token
- 4 Desk boards
The Game in a Nutshell
(De horribilis gamesibus, quickitur)
- To brew your Potions, take one Ingredient marble from the Dispenser each turn, and make Ingredients of the same color collide to make them explode (and take them too)! The bigger the explosions, the faster you’ll brew your potions!
- Each Potion recipe may need between 4 and 7 Ingredients. They are represented by the holes on the Potion tiles themselves.
- Put the marbles of the correct color on your Potion tiles: when all the holes have been filled with a marble of the corresponding color, the Potion is completed.
- Each Potion is worth a certain number of points, which depends on the number of Ingredients needed to complete it and the strength of the magical power it grants.
- When a player completes 3 Potions with the same power, or 5 Potions with 5 different powers, they receive a Skill token, which is worth 4 points.
- When the required number of Skill tokens have been awarded, the end of the game is triggered.
- The player with the most points is the winner.
Game Setup
(Preparatio gameus)

- Each player receives a Desk board and places it in front of himself, leaving some space both above and below it.
- The player that most recently prepared a drink is the first player and takes the First Player token. This is just a reminder: it won’t change during the game. Players play in turns, in clockwise order.
- Take all the Potion tiles and remove 2 of the 8 different kinds of Potions, either randomly or by choice, and put them back into the box (they won’t be used during the game).
For your first few games, I suggest you to leave out the Balm of Uttermost Stickiness and Filter of Lavamancing potions. Only the most talented potion brewers possess the necessary expertise to handle them! - From the 6 remaining kinds of Potion tiles, take 2 random starter Potion tiles (marked with the symbol
) per player, and lay them out in the middle of the table, with the Recipe side (the one with the grey ribbon) facing up. Starting from the First Player and proceeding clockwise, each player takes one Starter Potion tile. Once all players have taken 1 Potion tile, each player takes a second Starter Potion tile, starting with the last player and proceeding counterclockwise. - Each player places their 2 starter Potion tiles, with their Recipe side up, on the two Bunsen burners of their Desk. This will be their Brewing area.
- Once all the players have chosen their Starter Potion tiles, shuffle the remaining tiles together and divide them into 5 stacks, with the Recipe side facing up.
- Put all the Ingredient marbles in the “tank” of the Dispenser, and make sure they roll down to completely fill the 5 tracks of the slide (see Refilling the Dispenser, page 7).
- Place all the Little Help tokens and the Skill tokens near the Dispenser. Put some of the Skill tokens in a “countdown” stack (see End of Game, page 9). The number of Skill tokens to be put in this stack depends on the number of players:
- 2 players: 4 Skill tokens
- 3 players: 5 Skill tokens
- 4 players: 6 Skill tokens
You’re ready to go!
Game Turn Overview
(Turnis explanatio)
A game of Potion Explosion™ is played in turns. Players take turns in clockwise order. During your turn:
- You MUST choose and take 1 Ingredient marble from the Dispenser. This may trigger one or more Explosions.
- In addition, at any point during your turn, you MAY drink one or more of your completed Potions AND/OR ask for a Little Help from the Professor.
Taking Ingredients
(Ingredientorum pick)
As described above, to take an Ingredient from the Dispenser, you simply have to choose and take one. You can freely choose any marble that is visible on the Dispenser, except for the 9th marble on each slide track (see diagram). This is your regular pick for the turn.

Triggering an Explosion
(Causatio boom boom)
As you can easily imagine, when an Ingredient marble is removed from the slide, all the marbles above it will roll down to fill the gap. This is when an Explosion can occur!
- If two Ingredient marbles of the same color collide, they explode. When two Ingredients explode, all of the Ingredients of that color connected to them also explode. You take all of the exploding Ingredients, just like the one you directly picked from the Dispenser.
- If, after removing all of the exploding Ingredients, there is another collision between marbles of the same color, this new collision will trigger another Explosion, and you also take all of those exploding Ingredients. If, after that, another collision between marbles of the same color occurs, a third Explosion will happen, etc. (see example).
Not all students notice this at once: when there are three or more connected marbles of the same color, if you pick one of those from the middle, you still trigger an Explosion by making the others collide! That’s a pretty neat move, don’t you think?
Note that those two blue Ingredient marbles in the last step of the example—even though involved in a collision—do not explode. An Explosion occurs only when two or more marbles of the same color collide with each other. Moreover, if you trigger a particularly big chain of Explosions, one or more slide tracks can end up being partially empty. This is not a problem.
With a Little Help from the Professor
(Professorum helpus capiendum est)
At any point during your turn (and only once per turn), before or after your regular pick, you MAY ask for a Little Help from the Professor—i.e. take a Little Help token and 1 Ingredient marble of your choice from the Dispenser.

When you take an Ingredient marble using the Little Help from the professor, you cannot trigger an Explosion, even if you make 2 marbles of the same color collide.
For each Little Help token you lose 2 points at the end of the game.
It’s better to ask for my Little Help before you take your regular pick for the turn. If you do it wisely, you can create the perfect conditions to trigger huge chain reactions!!!
Using the Ingredients
(Usando marbles ad victoriam)
After taking Ingredients, either with your regular pick, a Little Help from the professor, or by drinking a Potion (see Drinking Potions, page 7), you will have a number of marbles in hand. To use them, you have the following options:
- First, you must place any Ingredients in your hand on the matching empty holes of the same color on any Potion tiles brewing on your Desk, if possible (a yellow marble goes on a yellow hole, etc.). Once an Ingredient has been placed on a Potion tile, it cannot be moved until the Potion is complete.
- If you have Ingredient marbles in hand that you cannot place on any Potion tile in your Brewing area, you must place those Ingredients in the small retort flask on your Desk. This is called your Ingredient Pool. During your turn, you may freely move Ingredients between your Pool and your hand.
The Ingredient Pool can only hold up to 3 Ingredients at a time. You can only hold Ingredients in your hand until the end of your turn (see End of Turn, page 7).
It goes without saying that, after you end your turn, you won’t be able to move Ingredients out of your Pool until your next turn starts.

Example: Heiko has 7 marbles in his hand: 4 red and 3 black. He has 2 blue marbles in his Pool left from his last turn. He places the 4 red marbles and 1 blue marble taken from his Pool on the Potions on his Desk. He wants to keep all the black marbles, so he takes the other blue marble from his Pool back into his hand and places the 3 black marbles into his Pool. Then he ends his turn, and discards the blue marble back into the Dispenser.
Completing a Potion
(Completius potionibus)
When all of the holes of a Potion tile have been filled with Ingredients, that Potion has been completed.
- Put all of the marbles from the Potion back into the Dispenser (see Refilling the Dispenser, page 7).
- Flip the Potion tile from its front (the Recipe side) to its back (the Completed side).
- Move it into the area below your Desk. This is your Potion area.
Potions are worth a certain number of points at the end of the game (as shown on the tile itself), and they can also be drunk to activate special one-time magical effects (see Drinking Potions, page 7).

Drinking Potions
(Gulpere potionibus)
At any time during your turn, you may drink one or more of the Potions you have completed to activate their magical effects. Each Potion is a one-use special power: once a Potion has been drunk, it can’t be drunk again.

- To show that a Potion was used, just rotate it upside-down. Then, you can apply its effects.
- When you use a Potion to take marbles from the Dispenser, you never trigger Explosions—Explosions can only be triggered when you use your regular pick for the turn. In the same way, you don’t trigger Explosions when you use a Little Help from the professor.
- Using a Potion does not make you lose the Potion tile: it still counts as a complete Potion, and it’s still worth the same number of points at the end of the game.
You can also drink Potions as soon as you complete them, if you wish. This exam aims to prove your worth as witches and wizards, not to merely test your theoretical knowledge of potions. Being able to make good use of the fruit of your labor and turn it to your advantage is a critical skill!
Refilling the Dispenser
(Dispenserium refillatus)
When you have to put Ingredient marbles into the Dispenser, you have to follow a couple little rules:
- Randomly roll the marbles onto the lid: Do not try to direct them to the entrance hole of any specific slide track.
- Fill all the slide tracks whenever possible: If one or more of the marbles end up laying on top of another marble (i.e. the track they ended up going into is already full, and they stick out from the lid), move them into the entrance hole of the nearest slide track with empty space.

End of Turn
(Endius turnum)
After you have taken your regular pick for the turn, you asked for the Little Help from the professor if you wanted to, and you have drunk all the Potions you intended to, your turn ends; follow these steps, in order:
- If you still have marbles in your hand and your Ingredient Pool is already full, you must discard them back into the tank of the Dispenser.
- If you have less than 2 Potion tiles in your Brewing area, you must choose and draw new Potions from the top of any of the five stacks available and place them on your Bunsen burners. Note: you may not move Ingredients from your pool to the Potion tiles you just drew, because you already finished your turn.
- Check to see if you earned one or more Skill tokens (see Skill tokens, page 8).
- Check to see if the game end has been triggered (see End of Game, page 9).
You will always have 2 Potion tiles in the Brewing area of your Desk at the beginning of each turn, and you won’t be able to complete more than 2 Potions in a single turn. Hah!
Skill Tokens
(Achievius rewardius)
Skill tokens are special rewards for students who prove themselves particularly talented… either by mastering one specific Potion, or for being able to brew a lot of different ones!
- For each kind of Potion, when you complete your 3rd Potion of that kind (i.e., with the same power), you automatically receive a Skill token (but you don’t gain another token if you complete 6 Potions of the same kind).
- Also, when you complete your 5th different kind of Potion (i.e., completing Potions with 5 different powers), you automatically receive a Skill token (but you don’t gain another Skill token if you complete a second set of 5 different Potions).
Skill tokens are received from the “countdown” stack (or from the general pool if the “countdown” stack is empty). Each Skill token is worth 4 points at the end of the game.

Example: By completing the potions depicted above, José obtained 3 Skill tokens at the end of the game. The first was obtained when completing the 3rd Filter of Lavamancing (A). The second was obtained when completing the 3rd Elixir of Blind Love (B). Note that even if José ended up completing 6 Filters of Lavamancing, he didn’t obtain a second Skill token (since the token is awarded when you complete your 3rd Potion of one same kind, not for each set of 3). Finally, the third was obtained when completing a 5th different kind of Potion (C). Again, even if he completed 6 kinds of Potions in total, no additional Skill token was awarded because the goal of “at least 5 different kinds of Potions” was already achieved.

I should not have to point this out, but… better safe than sorry: you don’t have to “create sets of Potion tiles” and “spend” them to receive Skill tokens. Think of each Skill token as an “achievement”: once you have obtained it once, you can’t obtain it a second time for the same reason. Also, a single Potion tile can be used to obtain more than one “achievement”.
End of Game
(Calculatio finalis pointibus)
During the game setup, you placed a certain number of Skill tokens into a “countdown” stack:
- 2 Players: 4 Skill tokens
- 3 Players: 5 Skill tokens
- 4 Players: 6 Skill tokens
If, at the end of any player’s turn, the last of the Skill tokens from the “countdown” stack has been taken, the end of the game is triggered. The end of the game is also triggered if, at the end of any player’s round, there are no more Potion tiles available.
The game continues, in clockwise order, until the player to the right of the First Player completes their next turn (so that all players will have played the same number of turns during the game). Even if the required number of Skill tokens have already been awarded, players can still earn more from the general pool, if they are able to do so.
We suggest these numbers of Skill tokens so that your games last a reasonable amount of time (not too short, not too long). But, if you have particularly slow or overthinking players at the table, or if you feel confident enough with the basics of the game, feel free to agree on a different number at the beginning of play, if you‘d like to have shorter or longer games!
Scoring
After this, all players calculate their final score:
- Add up the points obtained from all the completed Potion tiles.
- Add the points from all collected Skill tokens (4 points each).
- Subtract 2 points for each Little Help token held.
The player with the most points is the winner!
In case of a tie, all the tied players (starting from the First Player, in turn order) each take one marble from the Dispenser to try to trigger an Explosion. The player who takes the most marbles in this way is the winner.
Example: It’s a 4-player game. Heiko was the first player at the beginning of the game, and just finished his turn after taking the 5th Skill token from the “countdown” stack—his second—leaving one Skill token in the stack. Now it’s David’s turn. He manages to earn the last Skill token from the “countdown” stack, which triggers the end of the game. Jose and Anna will both have one final turn to play, then the game will end. José plays next, but does not earn any Skill token on his turn. During her turn, Anna manages to get 1 Skill token for “The 3rd Potion of one same kind”, and another for “The 5th different kind of Potion”. Since the “countdown” stack is empty, she takes them from the general pool. At the end of Anna’s turn, the game is over. The players can finally calculate their final scores.
List of Potion Effects
(De potionis effectibus)

Potion of Wisdom
Take one Ingredient of your choice from the Dispenser. No Explosions are triggered.
Nothing’s out of reach if you think it through.

Elixir of Blind Love
Steal all the Ingredients from 1 opponent’s Pool.
Why bother with theft, when all you need to do is unleash your dazzling charm?

Potion of Magnetical Attraction
Take 2 adjacent Ingredients of different colors from the same slide track of the Dispenser. No Explosions are triggered.
I don’t think this is what they mean when they say “magnetic personality”.

Potion of Prismatic Joy
You can place all Ingredients in your Pool on any holes of your incomplete Potions, regardless of their color.
Marbles? Colors? Who cares… let’s party!

Abyssal Draft
Take up to 1 Ingredient of each color from the bottom row of the Dispenser slide tracks. You can only take 1 Ingredient from each slide track.
This is what is called “scraping the bottom of the barrel”. A huge barrel.

Sands of Time
Activate again the effect of 1 Potion you already used.
We can always learn from our past mistakes… but we can gain even more from our past good moves!

Balm of Uttermost Stickiness
Take 2 or more adjacent Ingredients of the same color from the same slide track of the Dispenser. No Explosions are triggered.
This stuff is stickier than molasses! The thing is… how do you unstick this mess?

Filter of Lavamancing
Discard up to 5 Ingredients of 1 color from the same slide track of the Dispenser back into the tank. No Explosions are triggered.
Not exactly a surgical strike type of thing, but undeniably powerful.
Ingredient Legend
(Futilis riempitivus)

Unicorn Tears
Unicorn tears are the purest fluid known in the world of magic. Just use a few drops to catalyze very powerful magical effects.
Collecting unicorn tears is very easy! They are always depressed. Find one, make fun of his horn, and prepare for the shower. Bring a huge barrel.

Dragon Smoke
The toxic fumes exhaled by these dreadful reptiles are often used for their high magical reactivity. Beware, never, ever inhale them!
To obtain a dragon’s smoke, poke its nose until it gets really, really angry. Collect the smoke with a flask. Run before he incinerates you.

Ogre Mucus
This extremely viscous substance is used to thicken compounds otherwise too volatile. Always use a mask when you handle it.
Swamp ogres often take a cold. Go to a marsh. Bring a big box of paper tissue. Follow the sneezing. Not recommended for the faint of stomach.

Fairy Dandruff
A very powerful ingredient. Also used by naughty children who refuse to grow up, to kidnap other kids and lead them astray.
Catch a fairy and gently brush its hair with a small comb. Avoid happy thoughts, or you may find yourself smashing through the ceiling in no time.

The Game in a Nutshell
(De horribilis gamesibus, quickitur)
- To brew your Potions, take one Ingredient marble from the Dispenser each turn, and make Ingredients of the same color collide to make them explode (and take them too)! The bigger the explosions, the faster you’ll brew your potions!
- Each Potion recipe may need between 4 and 7 Ingredients. They are represented by the holes on the Potion tiles themselves.

- The player with the most points is the winner.
Game Setup
Game Setup
(Preparatio gameus)

- Each player receives a Desk board and places it in front of himself, leaving some space both above and below it.
- The player that most recently prepared a drink is the first player and takes the First Player token. This is just a reminder: it won’t change during the game. Players play in turns, in clockwise order.
- Take all the Potion tiles and remove 2 of the 8 different kinds of Potions, either randomly or by choice, and put them back into the box (they won’t be used during the game).
For your first few games, I suggest you to leave out the Balm of Uttermost Stickiness and Filter of Lavamancing potions. Only the most talented potion brewers possess the necessary expertise to handle them! - From the 6 remaining kinds of Potion tiles, take 2 random starter Potion tiles (marked with the symbol
) per player, and lay them out in the middle of the table, with the Recipe side (the one with the grey ribbon) facing up. Starting from the First Player and proceeding clockwise, each player takes one Starter Potion tile. Once all players have taken 1 Potion tile, each player takes a second Starter Potion tile, starting with the last player and proceeding counterclockwise. - Each player places their 2 starter Potion tiles, with their Recipe side up, on the two Bunsen burners of their Desk. This will be their Brewing area.
- Once all the players have chosen their Starter Potion tiles, shuffle the remaining tiles together and divide them into 5 stacks, with the Recipe side facing up.
- Put all the Ingredient marbles in the “tank” of the Dispenser, and make sure they roll down to completely fill the 5 tracks of the slide (see Refilling the Dispenser, page 7).
- Place all the Little Help tokens and the Skill tokens near the Dispenser. Put some of the Skill tokens in a “countdown” stack (see End of Game, page 9). The number of Skill tokens to be put in this stack depends on the number of players:
- 2 players: 4 Skill tokens
- 3 players: 5 Skill tokens
- 4 players: 6 Skill tokens
You’re ready to go!
How to Play
Game Turn Overview
(Turnis explanatio)
A game of Potion Explosion™ is played in turns. Players take turns in clockwise order. During your turn:
- You MUST choose and take 1 Ingredient marble from the Dispenser. This may trigger one or more Explosions.
- In addition, at any point during your turn, you MAY drink one or more of your completed Potions AND/OR ask for a Little Help from the Professor.
Taking Ingredients
(Ingredientorum pick)
As described above, to take an Ingredient from the Dispenser, you simply have to choose and take one. You can freely choose any marble that is visible on the Dispenser, except for the 9th marble on each slide track (see diagram). This is your regular pick for the turn.

Triggering an Explosion
(Causatio boom boom)
As you can easily imagine, when an Ingredient marble is removed from the slide, all the marbles above it will roll down to fill the gap. This is when an Explosion can occur!
- If two Ingredient marbles of the same color collide, they explode. When two Ingredients explode, all of the Ingredients of that color connected to them also explode. You take all of the exploding Ingredients, just like the one you directly picked from the Dispenser.
- If, after removing all of the exploding Ingredients, there is another collision between marbles of the same color, this new collision will trigger another Explosion, and you also take all of those exploding Ingredients. If, after that, another collision between marbles of the same color occurs, a third Explosion will happen, etc. (see example).
Not all students notice this at once: when there are three or more connected marbles of the same color, if you pick one of those from the middle, you still trigger an Explosion by making the others collide! That’s a pretty neat move, don’t you think?
Note that those two blue Ingredient marbles in the last step of the example—even though involved in a collision—do not explode. An Explosion occurs only when two or more marbles of the same color collide with each other. Moreover, if you trigger a particularly big chain of Explosions, one or more slide tracks can end up being partially empty. This is not a problem.
With a Little Help from the Professor
(Professorum helpus capiendum est)
At any point during your turn (and only once per turn), before or after your regular pick, you MAY ask for a Little Help from the Professor—i.e. take a Little Help token and 1 Ingredient marble of your choice from the Dispenser.

When you take an Ingredient marble using the Little Help from the professor, you cannot trigger an Explosion, even if you make 2 marbles of the same color collide.
For each Little Help token you lose 2 points at the end of the game.
It’s better to ask for my Little Help before you take your regular pick for the turn. If you do it wisely, you can create the perfect conditions to trigger huge chain reactions!!!
Using the Ingredients
(Usando marbles ad victoriam)
After taking Ingredients, either with your regular pick, a Little Help from the professor, or by drinking a Potion (see Drinking Potions, page 7), you will have a number of marbles in hand. To use them, you have the following options:
- First, you must place any Ingredients in your hand on the matching empty holes of the same color on any Potion tiles brewing on your Desk, if possible (a yellow marble goes on a yellow hole, etc.). Once an Ingredient has been placed on a Potion tile, it cannot be moved until the Potion is complete.
- If you have Ingredient marbles in hand that you cannot place on any Potion tile in your Brewing area, you must place those Ingredients in the small retort flask on your Desk. This is called your Ingredient Pool. During your turn, you may freely move Ingredients between your Pool and your hand.
The Ingredient Pool can only hold up to 3 Ingredients at a time. You can only hold Ingredients in your hand until the end of your turn (see End of Turn, page 7).
It goes without saying that, after you end your turn, you won’t be able to move Ingredients out of your Pool until your next turn starts.

Example: Heiko has 7 marbles in his hand: 4 red and 3 black. He has 2 blue marbles in his Pool left from his last turn. He places the 4 red marbles and 1 blue marble taken from his Pool on the Potions on his Desk. He wants to keep all the black marbles, so he takes the other blue marble from his Pool back into his hand and places the 3 black marbles into his Pool. Then he ends his turn, and discards the blue marble back into the Dispenser.
Completing a Potion
(Completius potionibus)
When all of the holes of a Potion tile have been filled with Ingredients, that Potion has been completed.
- Put all of the marbles from the Potion back into the Dispenser (see Refilling the Dispenser, page 7).
- Flip the Potion tile from its front (the Recipe side) to its back (the Completed side).
- Move it into the area below your Desk. This is your Potion area.
Potions are worth a certain number of points at the end of the game (as shown on the tile itself), and they can also be drunk to activate special one-time magical effects (see Drinking Potions, page 7).

Drinking Potions
(Gulpere potionibus)
At any time during your turn, you may drink one or more of the Potions you have completed to activate their magical effects. Each Potion is a one-use special power: once a Potion has been drunk, it can’t be drunk again.

- To show that a Potion was used, just rotate it upside-down. Then, you can apply its effects.
- When you use a Potion to take marbles from the Dispenser, you never trigger Explosions—Explosions can only be triggered when you use your regular pick for the turn. In the same way, you don’t trigger Explosions when you use a Little Help from the professor.
- Using a Potion does not make you lose the Potion tile: it still counts as a complete Potion, and it’s still worth the same number of points at the end of the game.
You can also drink Potions as soon as you complete them, if you wish. This exam aims to prove your worth as witches and wizards, not to merely test your theoretical knowledge of potions. Being able to make good use of the fruit of your labor and turn it to your advantage is a critical skill!
Refilling the Dispenser
(Dispenserium refillatus)
When you have to put Ingredient marbles into the Dispenser, you have to follow a couple little rules:
- Randomly roll the marbles onto the lid: Do not try to direct them to the entrance hole of any specific slide track.
- Fill all the slide tracks whenever possible: If one or more of the marbles end up laying on top of another marble (i.e. the track they ended up going into is already full, and they stick out from the lid), move them into the entrance hole of the nearest slide track with empty space.

End of Turn
(Endius turnum)
After you have taken your regular pick for the turn, you asked for the Little Help from the professor if you wanted to, and you have drunk all the Potions you intended to, your turn ends; follow these steps, in order:
- If you still have marbles in your hand and your Ingredient Pool is already full, you must discard them back into the tank of the Dispenser.
- If you have less than 2 Potion tiles in your Brewing area, you must choose and draw new Potions from the top of any of the five stacks available and place them on your Bunsen burners. Note: you may not move Ingredients from your pool to the Potion tiles you just drew, because you already finished your turn.
- Check to see if you earned one or more Skill tokens (see Skill tokens, page 8).
- Check to see if the game end has been triggered (see End of Game, page 9).
You will always have 2 Potion tiles in the Brewing area of your Desk at the beginning of each turn, and you won’t be able to complete more than 2 Potions in a single turn. Hah!
Skill Tokens
Skill Tokens
(Achievius rewardius)
Skill tokens are special rewards for students who prove themselves particularly talented… either by mastering one specific Potion, or for being able to brew a lot of different ones!
- For each kind of Potion, when you complete your 3rd Potion of that kind (i.e., with the same power), you automatically receive a Skill token (but you don’t gain another token if you complete 6 Potions of the same kind).
- Also, when you complete your 5th different kind of Potion (i.e., completing Potions with 5 different powers), you automatically receive a Skill token (but you don’t gain another Skill token if you complete a second set of 5 different Potions).
Skill tokens are received from the “countdown” stack (or from the general pool if the “countdown” stack is empty). Each Skill token is worth 4 points at the end of the game.

Example: By completing the potions depicted above, José obtained 3 Skill tokens at the end of the game. The first was obtained when completing the 3rd Filter of Lavamancing (A). The second was obtained when completing the 3rd Elixir of Blind Love (B). Note that even if José ended up completing 6 Filters of Lavamancing, he didn’t obtain a second Skill token (since the token is awarded when you complete your 3rd Potion of one same kind, not for each set of 3). Finally, the third was obtained when completing a 5th different kind of Potion (C). Again, even if he completed 6 kinds of Potions in total, no additional Skill token was awarded because the goal of “at least 5 different kinds of Potions” was already achieved.

I should not have to point this out, but… better safe than sorry: you don’t have to “create sets of Potion tiles” and “spend” them to receive Skill tokens. Think of each Skill token as an “achievement”: once you have obtained it once, you can’t obtain it a second time for the same reason. Also, a single Potion tile can be used to obtain more than one “achievement”.
End of Game & Scoring
End of Game
(Calculatio finalis pointibus)
During the game setup, you placed a certain number of Skill tokens into a “countdown” stack:
- 2 Players: 4 Skill tokens
- 3 Players: 5 Skill tokens
- 4 Players: 6 Skill tokens
If, at the end of any player’s turn, the last of the Skill tokens from the “countdown” stack has been taken, the end of the game is triggered. The end of the game is also triggered if, at the end of any player’s round, there are no more Potion tiles available.
The game continues, in clockwise order, until the player to the right of the First Player completes their next turn (so that all players will have played the same number of turns during the game). Even if the required number of Skill tokens have already been awarded, players can still earn more from the general pool, if they are able to do so.
We suggest these numbers of Skill tokens so that your games last a reasonable amount of time (not too short, not too long). But, if you have particularly slow or overthinking players at the table, or if you feel confident enough with the basics of the game, feel free to agree on a different number at the beginning of play, if you‘d like to have shorter or longer games!
Scoring
After this, all players calculate their final score:
- Add up the points obtained from all the completed Potion tiles.
- Add the points from all collected Skill tokens (4 points each).
- Subtract 2 points for each Little Help token held.
The player with the most points is the winner!
In case of a tie, all the tied players (starting from the First Player, in turn order) each take one marble from the Dispenser to try to trigger an Explosion. The player who takes the most marbles in this way is the winner.
Example: It’s a 4-player game. Heiko was the first player at the beginning of the game, and just finished his turn after taking the 5th Skill token from the “countdown” stack—his second—leaving one Skill token in the stack. Now it’s David’s turn. He manages to earn the last Skill token from the “countdown” stack, which triggers the end of the game. Jose and Anna will both have one final turn to play, then the game will end. José plays next, but does not earn any Skill token on his turn. During her turn, Anna manages to get 1 Skill token for “The 3rd Potion of one same kind”, and another for “The 5th different kind of Potion”. Since the “countdown” stack is empty, she takes them from the general pool. At the end of Anna’s turn, the game is over. The players can finally calculate their final scores.

Potion of Wisdom
Take one Ingredient of your choice from the Dispenser. No Explosions are triggered.
Nothing’s out of reach if you think it through.

Elixir of Blind Love
Steal all the Ingredients from 1 opponent’s Pool.
Why bother with theft, when all you need to do is unleash your dazzling charm?

Potion of Magnetical Attraction
Take 2 adjacent Ingredients of different colors from the same slide track of the Dispenser. No Explosions are triggered.
I don’t think this is what they mean when they say “magnetic personality”.

Potion of Prismatic Joy
You can place all Ingredients in your Pool on any holes of your incomplete Potions, regardless of their color.
Marbles? Colors? Who cares… let’s party!

Abyssal Draft
Take up to 1 Ingredient of each color from the bottom row of the Dispenser slide tracks. You can only take 1 Ingredient from each slide track.
This is what is called “scraping the bottom of the barrel”. A huge barrel.

We can always learn from our past mistakes… but we can gain even more from our past good moves!

Balm of Uttermost Stickiness

This stuff is stickier than molasses! The thing is… how do you unstick this mess?

Not exactly a surgical strike type of thing, but undeniably powerful.

Unicorn Tears
Unicorn tears are the purest fluid known in the world of magic. Just use a few drops to catalyze very powerful magical effects.
Collecting unicorn tears is very easy! They are always depressed. Find one, make fun of his horn, and prepare for the shower. Bring a huge barrel.

Dragon Smoke
The toxic fumes exhaled by these dreadful reptiles are often used for their high magical reactivity. Beware, never, ever inhale them!
To obtain a dragon’s smoke, poke its nose until it gets really, really angry. Collect the smoke with a flask. Run before he incinerates you.

Ogre Mucus
This extremely viscous substance is used to thicken compounds otherwise too volatile. Always use a mask when you handle it.
Swamp ogres often take a cold. Go to a marsh. Bring a big box of paper tissue. Follow the sneezing. Not recommended for the faint of stomach.

Fairy Dandruff
A very powerful ingredient. Also used by naughty children who refuse to grow up, to kidnap other kids and lead them astray.
Catch a fairy and gently brush its hair with a small comb. Avoid happy thoughts, or you may find yourself smashing through the ceiling in no time.
