Having bought the large addictaball as a Christmas gift, we were eager to try the small one too. Although at first sight it looks very similar to the larger version, as some of the obstacles are in fact the same, there are also plenty of stages which are completely different, so both versions offer different challenges. Like the larger ball, the small addictaball is very frustrating and very addictive! Having played with both balls extensively, I would actually say that the smaller ball is the more difficult of the two. Don't be deceived by the the bright colours and chunky design, this is not just a toy for children - every adult I know who has tried it has had difficulty putting it down, and I still don't know anyone who's been able to complete it!
