There is a funny chess variant on F-Droid called Open Chaos Chess <https://github.com/CorruptedArk/open-chaos-chess https://github.com/CorruptedArk/open-chaos-chess> where the players choose what piece should be played but the move is chosen randomly. The first player to lose all pieces loses the game (there are no checks and mates).
