I have created a card game in which one of the mechanics relies a lot on trust, and would be very easily cheated.
The game is played in 5 rounds, and has a total of 15 tokens to spread as you wish through these rounds. The amount of tokens selected needs to be private until both players reveal them at the same time.
Knowing how many tokens your opponent uses would allow you to either let them waste their tokens, or make you win the round.
What would be the best method to prevent cheating?
