Yoko Chess is out now on the iOS App Store as a free download, and it's pretty damn weird.
Not that we'd expect anything less from the famed artist and singer.
A premium Doggie chess board, available for $2.99, designates different breeds for each piece.
Dachshunds are pawns, Labradors are rooks, Pinschers are bishops and Bulldogs are knights.
The Queen is a Dalmatian, while the King is an Alsatian.
Best of all, 20% of the net purchase price for Doggie Chess will be donated animal rescue organizations "where possible, within the territory of the player."
