Secret Code 13+4

About this board game

Secret Code 13+4 is a 15-minute game for 2–4 players about cracking numerical security codes during a secret museum mission.

The mission, named “Amun Re,” begins when a team of four cunning secret agents breaks into the museum. To get closer to the precious Amun Re mask, the agents must overcome the installation’s tricky light barriers.

Each code demands precise calculation. Players combine the numbers on the dice so their results match the displayed code numbers, using the arithmetic operation that gets the job done.

• Addition and subtraction
• Multiplication and division
• Matching calculated results to security code numbers
• Overcoming light barriers on the way to the mask

The challenge is to work with the available dice numbers and find the correct result. Every successful calculation helps advance the secret mission and brings the agents closer to their target.

In Secret Code 13+4, the first player to overcome all the light barriers reaches the precious Amun Re mask. With its focus on arithmetic combinations, code matching, and a race through the museum, the game turns simple number operations into a tense secret-agent challenge.
