Object: Checkmate or capture the opponent's King.
 
You can eat your own species (capture your own pieces). For such a big sacrifice you are compensated:
 
Main Variant (Cannibal's Foodstore):
In the main game, you are compensated by the fact that you can re-insert such a piece at any later time.
 
Variant 2 (Kill variant):
Here you are compensated by one more move with the same piece. You may pass that second move by double clicking the piece. After the second move, your turn invariably stops.
 
Apart from this, all standard chess rules apply.
