The objective of the game is to move the largest block off the bottom of the screen to the bottom middle position. The block in blue must be the largest and can be moved in any direction.

The game starts with a random layout of the pieces on the board. It is your job to move the blocks in the best way possible, creating open space on the board. The app will save all of your moves and allow you to undo them if you get stuck.

It is possible to use the app's solver to help you solve the puzzle if you get stuck.
