It is Hungarian. I saw this in July, it sold for about $2 USD in an auction I didn't have access to.
It seems interesting, but it might not be a puzzle. It says "tutorial" on it, maybe a multiplication table tutorial?EDIT: the subjects on the booklet cover (and on the side of the box) make me wonder if there are questions inside the booklet and the right answers will "unlock" the "puzzle". Just a guess.
See two more pictures below.
