Il circo dei contrari has 50 tiles of varying difficulty, to be shuffled, placed face down and matched in pairs according to the opposing quality of the situation that characterises the character illustrated on the tile (tiger, lion, trapeze artist, clown, giraffe, elephant, mouse). If in doubt about the pairing, bring the sides of the tiles together at the point where the white symbol is located. If the symbol is completed by matching the two tiles, the pair is correct and the player continues the game. Whoever wins the most pairs wins. The pairs are divided into two levels of increasing difficulty; you start with a limited number of pairs to learn the game mechanism, then increase the number of tiles and 'turn on' the challenge. The game proposal, organised by quantity and quality of images, allows the stimulus to be customised according to the players' skills. —description from the publisher (translated)
