It's like chess, but randomized. First select the board dimensions, then press start. Click a piece to move it. Once you select a piece, you can not deselect it. A piece has a randomly selected move set each game you play. Take an opponent's piece by moving onto that square. You can even take your own pieces(although that's not usually recommended). A royal(the different colored pieces) cost 4 lives. Take all of your opponents lives to win. If you move a piece 4 times in a row, it will be destroyed after it's 4th move.
All coded by me, but the idea for the game is based off of a mobile game of the same name.
