Innovative game and difficult This game is really innovative and creative. First 9 levels are pretty easy, Level 10 though, it gets really hard.
Nice First 12 levels are very easy. 13 onwards it gets interesting. Nice way to pass some time and exercise those rusting grey cells.
New Idea Gets very difficult from level 3 onwards. Still trying. But this is a great new idea for a puzzle. Very enjoyable.
Not easy This is a good game if you want a challenge. It's easy to understand but hard to beat. Worth a try.
Fun Puzzle I enjoy IQ games and this new one is taking up all my time. One of the most challenging out there. Try it.
Clever and challenging Lots of good problems to solve and well graduated
