Put your dexterity skills to the ultimate test with the Impossiball 3D Puzzle Ball. The large see-through ball contains a complex maze and a metal ball bearing. Rock and roll the puzzle ball to move the ball bearing through the maze. It may sound simple, but with tricky stair cases, slides, shuttles, drops and chicanes to tackle, it’s addictively difficult. The puzzle ball features three starting gates to take three different routes around the maze. Once you’ve conquered it, why not challenge a pal to see who can complete it the fastest? It’s a great gift for puzzle fans! Impossiball 3D Puzzle Ball measures Ø19cm (approx.). Suitable for ages 6 years and over.
