very good game for both young children (my 6 year old son already plays there) than for adults. levels rise quickly in dificult but the 4 levels of 10 puzzles each leave the margin! this game is used by some psychologists in the suspicion of a precocious child. this game is very easy to store because the cards are inserted into a small drawer on the front and cars start in a small cloth bag provided. In short very well
