Rules and probabilities
Chance of at least one first prize in 1,000 automatic games
0.0123%Each draw is independent. Earlier results do not change the odds of the next draw.
Each draw selects six distinct winning numbers and a separate bonus number from 1 to 45. Automatic mode selects six fresh numbers for each game. Fixed mode uses your chosen numbers for all games. Automatic games can share the same combination.
Prizes follow the real Lotto 6/45 rules. The first-prize chance is 1 ÷ C(45, 6). For N automatic games, the chance of at least one first prize is 1 − (1 − 1/8,145,060)N. Fixed mode uses the same numbers for every game in a draw, so N is the number of draws.
The browser creates a random seed. The same version, settings and seed reproduce the same result. Number selection uses unbiased random sampling and a partial shuffle. There is no number prediction or real purchase feature. Draws run in your browser. Shared links include settings, the replay seed and any manually selected numbers.

My luck:
Why this probability?
This is a theoretical probability, not a ranking of real visitors. It uses this result alone, separately from cumulative challenge spending. The odds of the next draw stay the same.
Cumulative records include only experiments continued on this page. Refreshing or leaving and returning resets them. The next challenge after the first jackpot starts a new record. No real money is spent.
