Digital Chocolate has released Diamond Islands, a simple, but addictive tiki-themed puzzle game for iPhone. The object of the game is to push tiki end-over-end from point to point, either upright or sideways, picking up diamonds along the way. Triggered bridges, rafts, and platforms add to the challenge. A free trial version is available.
$2.99, for iPhone and iPhone touch with 2.2.1 update or better
