Summary: I'm not going to go into a lot of detail in this review as that has already been covered by others. This game is extremely addictive and is such a great value. There are a ton of puzzles that will keep you busy for quite some time, and for much of the game they aren't too difficult, but as you get near the end they do get quite challenging! If you're looking for a relaxing puzzle game, this is for you. I love doing a few puzzles after work to de-stress.
