Built for players who think statistically.
Most roulette apps are either basic scorecards or make wild claims about "guaranteed predictions." Neither is useful to someone who actually understands probability.
We built Roulette Ace for a different kind of player — one who tracks their own data, applies statistical methodology, and makes informed decisions rather than relying on gut instinct or superstition.
The app is built by CodeCraft Solutions LLC, a small software company focused on data-driven mobile tools. Roulette Ace is our flagship product.
Depth of analysis
Statistical engine rankings and two native on-device bias estimators summarize each recorded session. Diagnostics remain separate from evidence-backed scoring.
On-device analysis, secure sync
Statistical calculations and Bias Estimators A and B run locally on your phone. Your encrypted tracking records synchronize to your mandatory Firebase account, and an optional profile photo is cached locally with an owner-only copy in Firebase Storage, so both can be restored on another signed-in phone.
Honest about what it is
We do not claim Roulette Ace can predict an independent roulette spin. Roulette is a game of chance. The app summarizes recorded data and can help identify anomalies or possible mechanical bias when sufficient wheel-specific evidence exists.
Built for serious use
The UI is designed for quick spin entry at a real table — large number input, haptic feedback, session management that doesn't get in your way.
Every physical roulette wheel is a mechanical device with manufacturing tolerances and wear characteristics. Mechanical bias is possible, but it must be supported by sufficient wheel-specific evidence rather than a short run of outcomes.
Statistical analysis has been applied to roulette since at least the 19th century. The mathematician Karl Pearson famously analysed Monte Carlo results in 1894. Legendary players like Joseph Jagger ("the man who broke the bank at Monte Carlo") and the Pelayo family in the 1990s used systematic observation to exploit biased wheels.
Roulette Ace brings statistical methods and two native distribution estimators to your phone. It is a tool for tracking, statistical analysis, and entertainment. What you do with the analysis is your responsibility.
