This game is not only a challenge but also a real fun game. It's simple to play but hard to master. Don't worry, you will get plenty of hints to help you along the way. If you still have trouble, try playing the medium level. This is where you will find the hardest puzzles. However, if you are a good player, you can get through them without any hints.

As you progress, you will find the level of difficulty increases. In the hard level, you will have to solve puzzles without any hints. The only way to get through the hard level is to use your own logic to solve the puzzles.
