Click and drag a tile from the bottom of the screen to put on top of the red cubes to make the square blue. There are three different modes: Easy, Medium, and Hard. Medium includes white blocks that act as barriers. Hard includes the option to rotate the puzzle pieces by clicking on the button in the bottom right corner.

Can you make all the squares blue?
