Love the disc color options, the ability to play absurdly high # of disc games, etc... wish there was more than 1 undo, though, because the swipe movements aren't always super accurate, esp not when I'm trying to be fast. And it's disheartening to lose a perfect game bc my phone didn't agree that the swiping I did was far enough, which I only noticed two turns later, while already 3/4 of the way through a 13 disc game... orz

This is the only good Tower of Hanoi app out there, in fact it's perfect. Tapping disks instead of dragging makes for better gameplay. No flashy graphics or animations, just the bare puzzle.
