Pick a truly random number — or up to 1,000 of them — between any minimum and maximum. Raffles, dice rolls, classroom picks, giveaways, and settling arguments: set your range and draw.
Every integer in your range has an equal chance on each draw. Choose “no duplicates” for raffle-style draws where each number can only win once.
A fair draw means every number in the range has exactly the same chance on every pick: 1-in-(max−min+1). With duplicates allowed, each draw is independent — rolling a 7 twice in a row is just as likely as any other pair. With duplicates off, each drawn number is removed from the pool, so the odds of each remaining number rise as the draw goes on, exactly like dealing cards.
| Output | Formula | What it means |
|---|---|---|
| Drawn number | floor(random × range) + min | One fair pick — every integer in [min, max] equally likely. |
| No-duplicate draws | partial Fisher–Yates shuffle | Each number appears at most once, like names from a hat. |
| Draw spread | max(draws) − min(draws) | How wide your set of draws landed — small spread, tight cluster. |
A classroom raffle has 50 tickets, numbered 1–50. Set minimum 1, maximum 50, draw 1 number, no duplicates. Each ticket has exactly a 1-in-50 (2%) chance — the teacher's ticket 7 is no luckier than ticket 50. Drawing a second winner? Run it again with the same settings: each remaining ticket now has a 1-in-49 chance. For a lottery-style 6/49, set minimum 1, maximum 49, count 6, no duplicates, smallest-first — you get a sorted set of six unique numbers.
Draws use your browser's built-in random generator, which is statistically uniform but not cryptographically secure — fine for games, raffles, classrooms, and decisions, but never for passwords, tokens, or anything security-related. “Random” also means streaks happen: three 1s in a row from 1–10 is unlikely, not broken.
Drawing names instead of numbers? Pair this with a list, or use the countdown calculator to time your giveaway. For classroom math, the final grade calculator is the usual next stop.
Bright Side Kit. "Random Number Generator." https://brightoolbox.com/random-number-generator/ Accessed October 21, 2026.They are uniformly random: every integer between your min and max has exactly the same probability on each draw. They come from your browser's built-in random generator — statistically sound for games, raffles, and decisions, but not certified for cryptography or gambling.
Number your entries 1 to N, set the minimum to 1 and the maximum to N, draw 1 number with “no duplicates”. For multiple winners, raise the count — each number can only win once.
Because “allow duplicates” treats every draw as independent — like rolling a die, the last roll never influences the next. Switch to “no duplicates” if repeats should be impossible.
Up to 1,000 per draw. With “no duplicates”, the count cannot exceed how many integers exist in your range (e.g. at most 50 unique numbers from 1–50).

For casual giveaways, yes — the draw is uniform and transparent. For regulated contests or anything with significant prize value, use a certified third-party drawing service and keep records; this tool keeps no audit trail by design.
No. Browser random generators are predictable enough that they must never be used for passwords, tokens, or security codes. Use your password manager's generator for those.
