Game description from the publisher: Tonight is the night the secret mission "Amun Re" begins. The team, made up of four cunning secret agents, breaks into the museum and thanks to their precise calculations cracks the tricky codes of the security installation. Be it through addition or subtraction, multiplication or division, the numbers on the dice have to be combined so that the results coincide with the code numbers. Who in Secret Code 13+4 will be the first to overcome all the light barriers to get hold of the precious Amun Re mask?
Secret Code 13+4 supports 2–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Secret Code 13+4 is 15 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Secret Code 13+4 for ages 8 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Secret Code 13+4 has a complexity rating of 1.3 out of 5 from BoardGameGeek players, which makes it a light game.
