A few months ago, we tried playing algorithms and math charades, which actually worked out pretty well (although the PCP theorem is pretty hard to act out). Yesterday we invented a new variant (maybe this already exists)?
Everyone chooses a secret word and writes it down.
We take turns, and on your turn, you write down another word on a slip of paper and pass it to a player of your choice. They have to act out the word on the paper while the remaining players guess it.
Your goal is for the guessers to say your secret word.
Once the guessers successfully guess the word on the paper, all other players get to guess once what your secret word is. If their guess is correct, then you lose a point.
If they don’t guess correctly and one of the guessers said your secret word, then you win a point.
The incentives are to make the word you give to the other player very similar to your secret word, but if it’s too obvious, then the other players will guess your secret word. The game seemed to work OK when we tried it, but it might be breakable.
