This is a jigsaw puzzle, somewhat similar to Rubiks Cube, but it is 2D.
Slide the square grid with your finger. The whole row or the whole column will be moved when you move a square gird. The square grid moving out of the box will appear on the other side.
The goal of the game is to put the disordered square grid in order. When all the grid s are moved to the correct position, the puzzle will be successful!
