Colored blocks are the main characters of the Slide, Stop game. They have a small flaw - a hole in the very middle, which worries them very much. This problem can be solved by finding a small square of the same color and size that will fill the void. Help the blocks get everyone to their small brothers. At the initial levels, you will operate on one element, and at subsequent locations, their number will increase and at the same time they will move at the same time. There is one more very essential condition - the blocks do not know how to slow down, that is, stop where you want. If the square element starts to move, it will stop only when it reaches the end of the path, keep this in mind.
