If anyone wants to use it feel free :)

- A poker game but everyone can choose an item to cheat (mirror to see one opponents cards, extra ace up the sleeve) 

- Another one also building on the same would be a simplified version "guess my number" where you have to roll 3x dies, and everyone has to say a number, the one with the highest number wins, if you challenge and are right, you win, if you challenge and are wrong you loose, if you are the last person and no one has challenged beforehand, the last person wins.

- Shop keeper game where half of the items are cursed, you need to determine which one are "good deals" and which ones are "too good to be true"
