Really fun to play with, the puzzles get progressively harder. The colours of the vehicles don’t match the cards but that just adds to the difficulty of the puzzles and doesn’t really matter as a vehicle is either two or three blocks in length. There is a key to help you figure them out. Younger children just like to play with the cars. Cards store in the base - would have been good if had a transparent lid to hold cars in, but looks nice on a shelf.
