This is a great little mind-bender of a game. Each board has the same objective - find the star. How you do that changes each time with no directions, you just have to figure it out.
Over the course of the last 2 days - I was able to get them all. Give it a try! You'll hate yourself until you figure it out - then you'll think you are the smartest person you know. Which, in my case, is actually true.
