Combine your precision touch and timing skills with your problem solving skills to get Rainbow Ball to the flag in the fastest possible time while collecting as many stars as you can along the way.Rainbow Ball will need to overcome obstacles like moving or rotating platforms and to trigger special switches along its journey. But don't worry, Rainbow Ball is not alone in its mission as it gets help from its friends like the dual personality Green/Rock Ball, the turbo charged Orange Ball and the powerful yet gentle Puffy the Cloud.There are 72 base levels, a further 30 unlock-able bonus levels and 11 preview levels.That's a total of 113 levels with more coming.
