good game 4 1

Finally, a game without batteries, or there is nothing to climb.
My 10 year old son to this game known to school and asked me. I thought it was the most difficult perplexus to conclude but apparently there are more complicated.
Indeed, he quickly realized these puzzles then and had no desire to do it again without arrêt.donc nice game for reflection, to learn patience and to deceive and again.
negative: very large so it is not that game that we take on holiday! and a bit expensive given the limited duration of the attention that my son brought him
