<p>Losing Chess is a game played by two people on a chessboard, with sixteen pieces (of six types) for each player. Each type of piece moves in a distinct way.
|
||||
The goal of the game is be unable to make a move, either by not having any piece left on the board, or
|
||||
by having all remaining pieces blocked.</p>
|
||||
|
||||
