So many mazes and puzzles out there that you get board of so quickly and are soon condemned to a life on a shelf gathering dust.

Not this one. "Just one more go, just one more go, I'll be there in a minute, just this next part and we can go" some of the things your friends and family will get sick of hearing you say in between your tears of frustration.

They come in 2 seizes; small (travel size) - retails at 7,99 featuring 100 stages and the large - retails at 15,99 with a 138.

The small may have less stages but is equally as hard because every little hand movement is greatly magnified with everything being on such a small scale and intricate.

The large will also drive you insane (please note if signs of insanity start to show i.e chewing pillows or referring to the Addictaball as My Precious, please see a doctor immediately) with the parts of the maze you can't even see chances are you will never be able to finish either of these in one go.
