Object: Capture all your opponent's Kings.
 
All pieces (apart from the Pawns) turn into other pieces depending on which square they land on. E.g. if a square shows a 'R', the piece turns into a rook.
Pawns promote at the eighth rank to the piece given by the letter on the target square.
 
There is no castling. The King(s) can move into check.
Note that you always have to have a King! You lose when you don't own a king anymore.
 
Apart from this, the standard chess rules apply.
 
There are four variants with different boards.
