Extinction Chess is almost the same game as classic chess,except some points listed below:
-There is no check or checkmate.
-The player who captures all opponent's pieces of one kind, i.e. all eight pawns, both knights etc., wins the game.
-It is also possible to capture the opponent's king (and that finishes the game immediately since the king is the only piece of its kind). Because there is no check, a king can move to a square which is attacked by an opponent's piece or make a castling through such square.
-Pawns can be promoted to any piece including a king. However, if the player promotes his/her last pawn, loses the game because he/she loses all pieces of one kind - pawns.
