Sugoku for Android
This is a very challenging game that triggers your brain. Perfect to proof your Maths abilities :).
Really entertaining game, great interface, different from the others of its kind and absolutely brain-crushing. The thing I like the most is that the puzzles can be as complicated as you want: from a simple time-passing game for traveling to a real mind-challenging task, worth every second of tension to complete the levels in time.
