This is a form of solitaire that my mother taught me, and she was taught by her mother. So I guess it was my grandma's solitaire! The rules are simple: stack cards according to suit and value until you only have one stack left. The catch: a card can only be stacked on the card right before it or three cards before it. That's it. The rules are simple, but it is deceptively difficult to win.
While the market may say this game is designed for phones, it works just as well on tablets. There is just a bit more free screen space, but as you play that should fill right up!
