A bright blue cube will become the hero of the Cube Slide game. He wants to escape from the gray boring world, but it is not so easy. There are a lot of gray blocks and, although they are unhappy with the appearance of a brightly colored block among them, they cannot allow it to break out of the gray mass. Once outside their world, the block will talk about grayness and no one will want to visit it. However, the blue block is determined to break out and you will help him with this. The process consists of quickly sliding the block in which you have to control it with the AD keys to dodge the gray obstacles encountered in Cube Slide.
