Secret Code 13+4

Secret Code 13+4 is a mental math board game in which players solve number puzzles to sneak past traps and recover a confiscated comic. After arriving just five minutes late to class, the players have lost their beloved comic to the math teacher, so a secret nighttime rescue mission begins. The teacher's house is full of traps, and each one can only be switched off by solving a math problem with addition, subtraction, multiplication or division. Players roll the dice and combine the numbers to crack each code. The first player to reach the safe and reclaim the comic wins. Available now at Boarding School Games - crack the code with mental math.
