Test your betting strategy.
Discover proven ones.
Test your strategy against millions of simulations, understand what drives its performance, and play with real data behind you.
Start for freeFrom idea to data in minutes
Submit a strategy, run the simulation, and get a full report on how it performs. No setup required.
Submit your strategy
Build your betting strategy using our flexible visual editor — no coding required. Need more control? A code extension lets you implement arbitrarily complex strategies.
Simulate at scale
Your system is automatically run through millions of simulations. The engine is repeatable, fair, and identical for all submissions.
Explore your results
Dive into your full simulation report, compare variants, and see how your system ranks against others.
Table games, rigorously simulated
Roll Buddy currently supports roulette in all major formats. More table games are on the roadmap — sign up to be notified when they launch.
See how yours compares
Every submitted system is ranked by simulation performance. Browse the leaderboard to benchmark your strategy against the best.
Stop guessing. Start knowing.
Most players rely on intuition. Roll Buddy gives you the data to understand your strategy before money is on the table.
Fair & repeatable engine
Every submission runs against the same simulation process. Results reflect the true behavior of your strategy — not luck of the draw.
Deep simulation reports
Drill into ROI curves, drawdown analysis, session stats, and round-level breakdowns for every variant of your system.
Code extension
Go beyond the visual editor with a Python scripting interface. Implement arbitrarily complex progression logic, conditional rules, and multi-stage strategies.
Variant comparison
Every system on the leaderboard exposes all its variants. Once you've identified a system, compare its variants side by side to understand exactly what drives performance differences.
Compete on the leaderboard
Your strategy doesn't exist in a vacuum. See exactly where it stands against every other submission and climb the ranks as you refine it.
Notifications
Stay informed on what matters — submission results, ranking changes, and platform updates — without having to check manually.
Start free. Scale when you're ready.
All plans include simulation reports and leaderboard access.
