Two kinds of random, one screen
- Lotto numbers: picks 6 unique numbers from 1–45, shown as colored balls by number range like the real draw. Choose 1, 3, 5, or 10 sets at once and copy one row or all of them.
- Fixed & excluded numbers: tap the 45-number board to lock in numbers you want (up to 5) and rule out ones you don’t; the rest is filled at random.
- Random picker: paste names, candidates, or prizes (one per line or comma-separated), set how many to pick, and it shuffles fairly and selects at random. Great for giveaways, ordering, or team assignments.
What are the odds?
Choosing 6 of 45 without order gives 8,145,060 combinations, so the jackpot odds of a single game are 1 in 8,145,060. (The bonus number is drawn separately on draw day for the 2nd-prize check; you never pick it.) However you pick — auto, manual, a generator, or fixed numbers — the odds are identical. A generator saves effort; it does not improve your chances.
What the colors mean
They follow the official Korean lottery convention: 1–10 yellow, 11–20 blue, 21–30 red, 31–40 gray, 41–45 green — the same colors as the televised draw.
An honest note on randomness
Numbers and draws use the browser's cryptographic random generator (crypto.getRandomValues), so no number is favored. It's still a tool for fun and convenience, not a substitute for an official prize draw. Your input is never uploaded — everything runs in your browser.
