Random Number Generator

Numbers are generated with your browser's cryptographic RNG and never sent anywhere.
자주 묻는 질문
How are the numbers generated?
Every number comes from your browser's cryptographic random source (crypto.getRandomValues) with rejection sampling to remove modulo bias, so each value in the range is equally likely. That is stronger than the ordinary Math.random(), which is fast but not built to be unpredictable or perfectly uniform. This random number generator never falls back to Math.random().
Do quick picks improve my odds of winning?
No. Every combination has exactly the same chance, whether you choose it yourself or use a quick pick — the draw has no idea how the numbers were picked. For scale, the odds of matching all six Powerball numbers are about 1 in 292,201,338. A lottery number generator only saves you time; it cannot beat the odds.
Are my numbers stored or sent anywhere?
No. Everything runs inside your browser and nothing is uploaded — no server ever sees your numbers. Only your last settings (range, count, options and chosen lottery) are kept in this browser's localStorage so the tool remembers them; the generated numbers themselves are never stored.
Which lottery rules are used, and are they current?
The four presets are accurate as of July 2026: Powerball draws 5 numbers from 1–69 plus 1 Powerball from 1–26; Mega Millions draws 5 from 1–70 plus 1 Mega Ball from 1–24 (the April 2025 revision); EuroMillions draws 5 from 1–50 plus 2 Lucky Stars from 1–12; and Korea's Lotto 6/45 draws 6 from 1–45. Bonus balls are drawn from their own separate pool, exactly like the official machines.
When should I turn duplicates off?
Turn duplicates off whenever each result must be unique — drawing raffle or giveaway winners, assigning seats or turn order, or splitting people into teams — so no number can repeat. Leave duplicates on for things like dice rolls or independent picks, where the same number can legitimately come up again.
