There are 5 types of balls each with different properties and gameplay characteristics. These include rubber, glass, steel, stone and paper. Levels include obstacles such as spikes and acid that destroy the balls on contact. Tilting your iPhone will allow you to build up momentum to jump obstacles and avoid danger. Part of the challenge, however, is also avoiding shattering your ball, so proper control becomes a major issue and you can't just speed through each level.
The game offers 3 play modes including Conquest, Challenge and Random Level challenge.
