Colorful blocks: square and rectangular will fill the fields on each of the sixty levels of the Only 1 Move game. Your task is to remove them, while according to the rules you can move only one block, that is, make the only correct move. As soon as you do it, the blocks will start moving down and, combined with the weight of gravity, will be removed, forming solid lines the width of the field. But it will be only in case of the correct decision. If you moved the wrong element, start the level again, but first think carefully in Only 1 Move.
