at least initially. It is made up of interest and invites you to play. One can always try again and you have to, because there is not an instruction manual for this. But that's the attraction. Sometimes you have to make an effort to get ahead of his brain. However ... and therefore only 2 stars .... when you get to a point where you really can not go any further, the game is also quite fast uninteresting. No possibility of help and I find that very unfortunate. If one then a step finally has progressed and has made a mistake, the whole level you have to again and again from the beginning to play might get ahead a step. However, I just gave up after about 10 times (50th-felt) out of frustration :( Too bad
Conclusion: Even recommended, perhaps create another just as I did.
