This is a 3D rendition of a classic logic puzzle. Usually it’s two dimensional consisting of black and white squares that change colour based on your selection. In this version, the display is 3D blocks that move up and down.
You do this by pushing a block down, or pulling a block up by clicking it. This will also alter the state of each ajoining block. If a block was up, it will move down. If the block was down, it will move up.
Your score is the number of moves you made. Try to get all blocks in the down position, in as few moves as possible. Good luck!
