Decrypto pits two teams against each other. The general idea of the game is to transmit information to your own team without the other team understanding. To win you have to walk a fine line: The instructions you give need to be clear enough for your teammates to understand, while at the same time obscure enough to baffle your adversaries!
Each round, both teams appoint one of their members to be the Encryptor, whose job is to transmit a secret 3-digit code to their teammates without the opposing team intercepting the code. If you succeed in guessing the opposing team's code, you win an Interception Token. If you manage to get 2 Interception Tokens, your team wins!
