Clever Puzzle Game A decent graph-theoretical challenge. However, purchases for access to the hard challenges won't work for me :-/
Nice, but not worth $ I've solved all the free levels. It's a good brain twister, but not worth $ for extra levels.
Best puzzle It makes you think without getting too hard to fast. Awesome. Favourite puzzle game yet
Awesome I liked it ; it can be moved just need is move to SD apps download it from apps market
Excellent puzzle I haven't found a puzzle this good in a while. The app is also ad free and does not require any permissions it doesn't need to do its job. It definitely deserves to be among the top free games.
