The game is made very kind and loving, there are many levels and a whole bunch of gimmicks that vary the basic principle and keep it interesting. A little reminds the Knobelei almost at chess.
The levels are rapidly demanding and to some I've almost been bitten my teeth, but I'm not quite clear on how to keep the game too difficult - with acquired credits can be at the levels at which you even after countless attempts is on the line, "buy" advice.
For the money, you really get a great value - says one who is not a chess fan.
