Knobel thinkers

I have this game only excerpts in
Seen Advertising and found the riddles quite interesting.
After much consideration, I decided this game
to buy.
I have played this game and puzzled. Some puzzles
were so simple that I said to myself, had to think well
I now not just. Other executed against were so "difficult"
I needed a lot of experiments and evidence to exceed this
to solve all. Other I do not know to this day what the
Solution is, or how to get it.
Those who like to solve such clouts and will keep fit his brain,
should invest the money and buy this game.
Also "Pandora's Box" is highly recommended.
