Backtesting · Real Historical Draws

Lottery backtesting — replay any strategy against every real draw.

Enter your picks, choose a game, and Lotto Oracle replays every historical draw to tell you exactly how your strategy would have performed: how many hits at each tier, what those hits would have paid, and your true ROI. No lucky-number magic — just deterministic math against real data.

Full history · every game
13,000+ real draws across 17 supported games — UK Lotto, EuroMillions, Powerball, Mega Millions, Oz Lotto, Irish Lotto, SuperEnalotto, German 6aus49 and more. Not simulated data. Real draws.
Deterministic math
Every backtest applies the exact prize-tier rules of the target game to your picks. Same math the operator uses — no rounding shortcuts, no bonus assumptions.
Honest ROI
See ticket-cost-out vs. prize-money-in as a real ROI percentage. Long-term ROI on random-draw games is negative — Lotto Oracle shows you that truth so you play informed.

Frequently asked

What does 'backtesting' actually mean for a lottery?

It means taking a strategy (a set of picks, a wheel system, a hot/cold approach) and replaying every historical draw as if you had played that strategy the whole time. You get an honest tally: hit count at each prize tier, total prize money, total ticket cost, and net ROI. It's what quantitative traders do for stock strategies — Lotto Oracle brings the same rigor to lottery play.

Can backtesting predict the next draw?

Absolutely not, and if a tool tells you it can, run. Historical draws are independent random events — past frequency provides ZERO information about the next outcome. What backtesting DOES do is show you what your strategy would have earned so far, which is useful for understanding: (a) how bad your ROI would actually have been, (b) whether a coverage wheel would have hit anything meaningful, and (c) whether the strategy is even self-consistent.

Which games can I backtest?

USA: Powerball, Mega Millions, Cash4Life, Lucky for Life. UK: Lotto, EuroMillions, Thunderball, Set For Life. Ireland: Irish Lotto. Italy: SuperEnalotto. Germany: 6aus49. Australia: Powerball, Oz Lotto, Saturday Lotto, Mon/Wed Lotto, Set For Life AU. That's 17 games total — the largest real-draw archive in one tool.

How far back does the historical data go?

Depends on the game: UK Lotto back to the 1994 launch, Powerball back to the 1992 launch, EuroMillions back to 2004, German 6aus49 back to 1991 (when the Superzahl was introduced). Free tier limits you to the last 12 months per game — Pro Researcher unlocks the full archive.

How is Lotto Oracle backtesting different from a spreadsheet?

A spreadsheet requires you to manually enter every draw, code every prize tier, and rebuild it for every game. Lotto Oracle already has 13,000+ verified draws and the exact prize-tier logic for 17 games. And every backtest is repeatable — you can share a saved strategy with a friend and they'll get the identical ROI report.
