Quantum Chess is a game, where you can make “Quantum moves”.

A Quantum move is two moves with the same piece, except it only has a 50% of working. (That is 50/50 either double move or zero moves this turn)

A Quantum moved piece is then marked as 50% chance of being on both squares. Both the original, and the two-moves-away location.

BUT… you can’t see if it worked. Once something happens that requires that piece to be there (usually, when you use it to take another piece) the uncertainty gets resolved and you get to see where it really was all along.

You can Quantum move, Quantum moved pieces, resulting in a 50/25/25 split, and pieces can be killed without you knowing if it was ever really there, or if the piece is still back at the starting point.

Fun concept, nice implementation. Requires _some_ interest in chess. Not a lot, but a bit
