There are various game modes, where the difficulty increases depending on age. The simplest method: 2 cards are placed and the children have to quickly find the animal and call, which can be seen on both cards. The animals are printed in different sizes, which does not make it any easier. It brings a lot of fun and the kids are highly concentrated, because everyone wants to be the first! We have bought the game for a child's birthday and there was a hit. From us there is something deduction, because the cards are too thin. We would also like 2-3 EUR spent more if we had for getting stable maps.
