King Clone 77 is played by two players on a 7x7 chess board. The object is to capture all of the opponent's Kings.
 
In principle the pieces move like in normal chess.
En passant moves by the pawns are allowed, and happen quite often because of the 7x7 board size.
Pawns promote to Kings or to Rooks only.
There is no stalemate. Castling is not possible.
 
 
The game is not overly nice. It is meant to show problems with human cloning. The zrf-file intentionally does not have sound nor music.
