This is Game #25 in the Games on Half a Checkerboard Series This game is a fusion of Lines of Action, Focus and Extinction Chess. In it, in order to keep pieces moving, a player must control at least one stack each containing 1 piece, 2 pieces, and 3 pieces. In order to move a stack on top of another stack, a player must have all their pieces on the board. If a player is unable to perform a legal move at the start of their turn, that player loses the game. Paul Beykirch also was part of the design process and is listed as a co-designer of the game.
