Rainbow Islands Revolution is a game on the Nintendo DS. It is an update of the original game, Rainbow Islands. Unlike in the original, the main character, Bub, rides in a bubble, and the player has to guide him with the stylus, and draw rainbows with it as well. Therefore, the game uses mainly the DS's touch screen.
The player has to drag Bub around using the stylus. Contact with enemies or dangerous objects such as spikes causes the player to lose a heart. When all hearts have been lost, the player loses a life and must begin the level anew.
When the player drags the stylus anywhere on the screen that isn't Bub, the player can create a rainbow. The rainbow serves as a barrier through which enemies can't cross. If the rainbow is drawn over an enemy, the enemy is killed. Additionally, when the player taps a rainbow, it falls down removing any enemies that lie below.
The player can also draw some special shapes which create rainbows with special effects.
In Story Mode, collect all 7 jewels in a world. When you defeat the boss of that world, a large jewel appears. Collect the large jewel from each regular world to find the 3 hidden worlds. This is how you get the true ending and unlock additional characters.
- Mike - beat world 10 with every large jewel (play with Bubby or Bobby)
- Violet - Using Mike, beat world 10 with every large jewel
- The game was due to be shipped free to purchasers of Bubble Bobble Revolution, which contained a major bug in the North American version of the game, though this did not occur.
