This is a logical task in which the child should choose the figure that differs from the specified figure by exactly one attribute (either shape or pattern). As the level of complexity grows, the introduction of an additional centre inside the figure makes the task more challenging. The centres can differ between themselves in shape and color.

Level "Novice": 2 features (shape and pattern)
Level "Pilot": 3 features (shape of figure, shape of centre, color of centre)
Level "Racer": 4 features (shape of figure, pattern of figure, shape of centre, color of centre)
