Two colours for two different levels of difficulty
Heavy Level - The blue maze ball that has more channels, narrower channels and small steel balls to increase the level of difficulty.
Medium level - We have reduced the difficulty of customs clearance, the passage is wider and the steel balls are larger, so even younger children can easily pass customs. Most difficult level - The green maze ball is the most difficult.
Easy level - The red ball is easier than others.
The best 3D maze puzzle toy for desk to stimulate inspiration and relieve stress. Also good for parent-child games.
