As previously mentioned, I'll be releasing a very old version of my roulette computer soon. It is nowhere near as capable the current computers, and it will not be fully functional because it lacks the firmware. However, it will run on most java capable phones. The idea behind the release is for everyone to get a feel for how roulette computers work.
Ultimately, on most phones, even without the custom firmware, you should be able to beat very basic tilted wheels. Purchasers need not be concerned in the least, and you'll understand why when you see the free version.
In the coming week or so I'll provide more details, including how you can obtain it - keep an eye on www.roulettecomputers.com
