Play losing chess against the AI, solve one of the 100 puzzles, or play against a friend on the same device.

Losing chess is one of the most popular chess variants. The overall goal of each player is to lose all of their pieces or be stalemated.

The rules are the same as those for standard chess, except for the following special rules:

- capturing is compulsory.

- The king has no royal power and it may be captured as any other piece.

- There is no check or checkmate and no castling.

- A pawn can be promoted to a king.

A player wins by being unable to make a move. This can be because he has no pieces left or his pieces are stalemated.
