I bought this game to pass the time in a queue or while traveling. This is a good puzzle with sheets "beginner" to "expert". I recommend trying to gradually get used to the idea of the concept and find the logic of the game. I even challenged my companion laughed to see play breeze and here he was taken to the game; Even my 5 year old son tried it from time to time to the first sheets with successes and failures. But it teaches perseverance and methodology. Yes, because there is some method to apply logic to not "waste" time and abut an impasse. I liked its compact packaging, solid (plastic storage box with hinged lid) and locations to store everything pawns, twists, and instructions easily portable and almost as big as a smartphone.
