Cube Stacker
As random blocks fall, can you stack them so there are no gaps? In 3D space, you may need to rotate them in two directions!
The objective of the game is to pack the pieces perfectly with no gaps. The possibilities are the seven Soma cube pieces. Any solidly-packed layers of cubes will be removed, making room for new pieces. The game ends if the space fills up with partial layers and there is no room for another piece. If you want more time to place the piece, swipe up on the blue arrow. Swipe down to place it immediately.
