This is a really great toy and not just for children!
The toy is a clear plastic sphere, inside is a 3-D maze, around which you have to guide a small ball bearing until you get it into the cup right at the centre. There are 138 moves, each one requiring a steady hand and an ability to think round corners as you try to work out how to tilt the sphere.
The maze is ingenious, with lots of clever obstacles for you to get around. The toy is quite well constructed and durable, and I can see it lasting a long time. It is also highly addictive and very frustrating! Once you have a go you will not be able to stop, and if you do complete it I guarantee you will be starting all over again straight away. It is hours and hours of fun.
As well as being fun, the game is a good educator/trainer - it promotes had eye co-ordination and problem solving abilities. All in all a great buy!
