This game contains two sets of 20 cards: one with images of the numbers from 1 to 20 and the spelling, and the other just with the pictures.

Rules:

The game starts with all the cards face down and players take turns to turn over two cards. If the two cards have the same number, then they keep the cards, otherwise they turn the cards face down again. The winner is the person with the most pairs when all the cards have been taken.
