Solve one of the most entertaining mathematical problems ever. Your goal is to move a stack of size-sorted discs from one bar to another. Two rules: Only one disc at once - and bigger discs may never be on smaller ones. The game can theoratically be played with an infinite amount of discs, we offer you ten; if you play on high speed, it takes something like 20 minutes and a lot of pain in the hand to solve it. That's why you get an achievement for that!
