You could say that 3D Cubes Unlimited is a kind of Sokoban, but applied to the letters, that is, you have several cubes that contain a letter inside, and you will have to move them around the board until you get to form the word indicated in each level.
But it will not be easy to place each of the cubes correctly, because you have to reflect a lot about your movements. A bad step can block other cubes or make it inaccessible to pass through one of the labyrinth tunnels, thus making it impossible to form the whole word. In total, you have up to 180 different levels and all in a striking three-dimensional environment.
For the correct operation of 3D Cubes Unlimited it is necessary to have OpenGL.
You can free download 3D Cubes Unlimited 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
