Move chess pieces to match at least 3 of the same pieces in a row or column. Click on the piece you want to move; you'll see where you can move the piece indicated by the green tiles. The pieces can only move to spots they can legally move to on the chess board. Click on the green tile to move the piece.

Pieces need to be the same color and type to make a match. You can mouse over a piece before clicking to see which spots it can move to. If you move a piece to a spot where another piece is, your piece will switch places with that piece. If you place a piece in a spot where there is an empty spot underneath it, it will automatically fall until it collides with another piece.

Every time you make a move, new pieces will fall onto the board from the top. At the top of the board, you can see which pieces will fall after your next move.

If a column fills to the very top, it's checkmate - your game is over!
