When you start the game and enter the main interface. In an 8X10 checkerboard, 2-3 rows of squares are randomly raised from the bottom. You can only move one square in the horizontal direction at a time, and there is space next to the square to be moved.
When you accidentally move an error you can click the back button to go back to the previous step
