The Ravensburger Super Mario puzzle set contains four colourful children's designs in one box. With increasing difficulty levels of 12, 16, 20 and 24 pieces, children aged three and over can gradually improve their skills. The four puzzles show well-known characters such as Mario and Luigi, the colourful Toads, Princess Peach with her friends, as well as Bowser and his followers. The large, sturdy puzzle pieces are specially designed for small children's hands. Assembling the pieces encourages concentration and fine motor skills.
