SumoChess - Chess Variant

SumoChess is a free app offering a Chess variant created by avid Chess players, looking for a twist in the rules that would add fun and novelty to the traditional Chess game.
In SumoChess you can only take pieces by pushing them off the board. Only the king can still take. That makes it more complex and intense than chess, as most of your pieces stay active, and you can have fun playing tricky moves by a well-placed push.
