Dan sent in a link to a new free game from CrucialSoft called RHex. The best way I can describe this game is kind of like a mix between Tetris and Dr Mario. If you have a better description let me know in the comments. The game is available for the Storm, Bold, & 8900 Curve but sadly only has a desktop install right now. Older devices will supposedly work with the Bold/Curve build but may not look right.
UPDATE: You can install it OTA at http://berryreview.com/ota/RHex/
I emailed the developer asking for an OTA install so hopefully we will have that shortly. The developer is also asking for donations if you like the game. Let me know what you think or check out the video below for some gameplay:
