Roulette Pro is an app on the statistical game of roulette. Great to play on roulette online. Clicking on the numbers drawn app warns when a combination (for the lite version only red and black, odd and even manque and passe while the paid version there are also columns, dozens, sextuplets, orphans, near zero, etc. ) reaches a considerable delay. The app can handle 3 levels of risk: low, medium and high. It is for the player to determine when to enter into play.
