Switch the pieces on the left to the right and vice-versa.
The objective of the game is to move the cards so that the hearts occupy the three leftmost locations and the spades the rightmost. You may move a card into an empty neighbouring location or you may jump a card of the other type into a empty location beside it. Hearts can only be moved to the left and spades only to the right.
You can also select to use coins instead of cards.
