New favorite game

I love the concept. I wish there was a timer to give hints after so many hours of gameplay in addition to purchasing, similar to Doors and Rooms. The "skins" are more difficult to read than the default. Some levels can be beat with fewer moves than the "best" number.

Makes you think

It's not too hard, or maybe I haven't gotten to the hard levels yet. But it's definitely something fun to pass the time.


This game is awesome I got it because my dad got it and at first I didn't no whether or not I was going to like it at first but as the game went on I started to like it. If u like games that make u have to think this game will be good for u
