Description by Gerard Grundy Written by the developer, not by AppBrain. Click to read.
Track the dozens and columns with just a tap!

To run the system all you need is a bankroll of $200. Though there are a lot of online casinos that will match your deposit amount. So you can just deposit $100 and they will give you $100 for free!

The Roulette Dozens Calculator tracks the numbers that are hit on each spin and logs how many times a dozen has not appeared. If a dozen has not appeared after five spins, chips will be displayed on the screen and you’ll be informed how much money to place on the next dozen. It’s a really easy system to use, has great winning odds and is a really fun way to play roulette!

Disclaimer: By buying this app you agree the developer is not responsible for any circumstances or any losses incurred.

Tested and works on IOS 8.0 and up
Click on app support to see how it works with the new undo and restart button. :)
