I N S I D E 3 is quite simple. Just a 3D maze played in the dark! Just free the ball and watch it fall in the dark. Then try to steer it to the other side. All you have to do is follow the map engraved on the surface. There are 12 different models, from a very simple suitable for children starting 8 up to a terrible one, all black and with no map. Enjoy... For Ages: 14+ Choking Hazard-Small Parts. Not for Children under 3 yrs.
