About this board game

Time Bomb is a secret-identity game for 4–8 players that plays in approximately 30 minutes. Agents must reveal all the success cards to defuse the bomb, while Terrorists aim to reveal the explosion card.

At the beginning of the game, each player is secretly assigned the identity of Agent or Terrorist. Players receive wire cards, look at them, and then shuffle them, creating uncertainty about which cards may help defuse the bomb and which may bring the game to an explosive end.

The game unfolds over a maximum of four rounds. Starting with the first player, participants select a secret card and play it. Every card has an action, and players continue taking actions in this way as they try to advance their hidden team’s goal while keeping their own identity concealed.

  • Agents win when all the success cards are revealed.
  • Terrorists win if the explosion card is revealed.
  • Terrorists also win if the fourth round ends without the bomb being defused.

With limited time, hidden loyalties, and secret cards constantly entering play, every choice can influence the bomb’s outcome. Players must interpret the available information, follow each action carefully, and determine whether the group is moving toward safety or disaster.

Released in 2016, Time Bomb offers a focused contest between two secret teams, with the result decided by card reveals and the pace of the four-round game.

London, 1890. Big Ben sits proudly atop Elizabeth Tower, the sound of its first toll echoing through the streets of the grand Victorian city. Passers-by are quietly enjoying the sunshine while strolling casually. There, amidst the background of laughter, stand Sherlock and his companions, still and silent.

Between two tolls, a ringing emerges from a pay phone box around the corner of the street. Sherlock picks up the receiver with a heavy heart. His face tenses and then he makes a mad dash toward the immense London clock.

At the first stroke of noon, Moriarty and his henchmen will trigger a bomb to destroy Big Ben.

Object of the Game

Moriarty has planted a bomb that he plans to detonate in the heart of Big Ben, while Sherlock rushes to defuse it. At the start of the game, you will secretly discover which team, Moriarty’s or Sherlock’s, you belong to and will try to identify your teammates without being unmasked by your adversaries. Each turn, you will choose a wire – displayed in front of another player – to cut, attempting to detonate or defuse the bomb according to which team you belong.

Sherlock’s team wins the game if they defuse the bomb, while Moriarty’s team wins if they detonate the bomb and destroy Big Ben.

The game is played over a maximum of 4 rounds during which you use the wire cutters to snip wires among other players hoping to complete your goal.

Overview of a round

Starting with the first player, take the Wire Cutters and place it in front of the Wire card you want to cut belonging to another player. Do not hesitate to discuss and listen to the arguments of each player before choosing which wire to cut. You cannot cut one of your own Wires. Then, reveal the cut Wire and place it in center of the table.

safe_wire_card_example
safe_wire_card_example

If it is a Safe Wire card, nothing happens.

defusing_wire_card_example
defusing_wire_card_example

If it is a Defusing Wire card, separate it from the other revealed cards to keep track of how many Defusing cards have already been found. If this is the final remaining Defusing Wire, the Sherlock Team wins the game immediately. Otherwise, the game continues.

bomb_wire_card_example
bomb_wire_card_example

In the case of the Bomb card, the Moriarty team immediately wins the game.

Then the player who was forced to reveal his Wire card takes the Wire Cutters and proceeds in the same way.

End of the round

The round ends when the number of Wire cards revealed during the round is equal to the number of players.

Example: With 5 players, the round ends after the fifth Wire card is revealed.

Gather all the uncut Wire cards (i.e. face down) among all players and shuffle them without looking. Deal new Wire cards, face down, so that all the players have the same number. Then repeat step 5 of the setup.

With each new round, each player has one card less than at the beginning of the previous round.

A new round begins, and the last player to have received the Wire Cutters during the previous round becomes the first player.


The game ends immediately if one of the following three conditions is met:

  1. All Defusing Wires are revealed. The members of the Sherlock team immediately win the game.
  2. The Bomb card is revealed. Members of the Moriarty team immediately win the game.
  3. At the end of four rounds, neither of the two above conditions have been reached. The members of the Moriarty team win the game.
