Cube Cube Cube is a unique 3D puzzle game. Break apart groups of blocks according to the numbers that are displayed on some of the blocks. Each number indicates the number of block faces in a group that you will need to separate. A group of faces will only contain blocks that are touching each other, and have one block with a number on it. When you successfully isolate a group, the blocks will turn green. If you try to remove a block that is part of a group, you will lose a pickaxe. You only have three pickaxes, so try to avoid making mistakes!
