This fascinating and tricky puzzle posesses logic-defying special effects! It features a lenticular image of interlocking cogs that turn as you twist the puzzle in your hand. Remove the 16 puzzle squares and muddle them up, then try to put the picture back together again!
Magnetic pieces are light and stick easily to the base which can also be used to store the pieces inside when not in use.
Great as a brain-teaser for an older child or adult and ideal for on the go fun.
