This is a very addictive and simple sliding block puzzle game in which you have to move a red block to the exit in order to get the stars and earn the crown. You will need to use your brains and logic, and the puzzles will get more difficult as you go further.

In each round, you will need to slide the blocks around and make a path for the special red one toward the exit. You will need to be patient and try to move the red block as far as you can and without any hints or help. But, should you get stuck, always remember that you can rely on hints to give you a gentle nudge to the correct direction.
