Great game

It’s a very fun game to play. At first it’s very frustrating and it may become more boring for some it takes a while. As you get closer and closer to finding out the solution, you get the rush of excitement and in the end when you do figure it out, you feel good about yourself. This game is so fun and useful for people to train their brain
