It is the second time I buy it, because my first one broke. It is nice and entertaining, it has "save" in two intermediate points, so you can continue.

I found it on sale for €14 and bought it for my children (3 girls). They are thrilled and even though they managed to complete it once, they keep trying constantly. I tried it myself and reached 1/3 of the course, at some points it requires technique to prevent the ball from falling and continue. However, at the starting point of the course, it has 3 "entrances" so you can continue from 2 additional points in the middle. This is convenient if you want to skip the difficult parts without redoing the entire course. It's not very big but not microscopic either, a primary school child can comfortably hold it in their hands and rotate it. If you want them to take a break from screens when you're at a restaurant or somewhere they get bored, it's ideal. But know that while they play, they won't "listen" to you when you talk to them because it requires concentration. :-D. Level 2 is playing it in the car!

Very nice. Worth the money. Makes you want to finish it without losing. Crazy addiction.
