Blocks collapse, bubble shooter and tetris combined! Clear the board by combining at least 3 adjacent pieces of the same color. Throw pairs of clocks from opposite sides. Try to make them land in the best position so that groups of at least 3 blocks of the same color are formed. You can see the prospective positions where the blocks will land by moving the mouse over the board. Release the blocks by mouse click; the goal is to clear the board.
