What is the Random Number Generator?
This free random number generator (RNG) draws one or many integers between any minimum and maximum you choose — 1 to 10 for a quick pick, 1 to 100 for the classic draw, or any range up to a billion in either direction. Click Generate and the result appears instantly, big enough to read across a room.
Need more than one number? Ask for up to 1,000 at a time, switch on No repeats to make every number unique, and Sort results to get them in ascending order. Your last ten draws stay visible so you can compare rounds, and one click copies the results for pasting into a spreadsheet or chat.
Common Ways People Use Random Numbers
- Giveaways and raffles: number your entries, then draw winners with no repeats for a provably fair result.
- Classrooms: assign each student a number and let the generator decide who answers next — or generate arithmetic practice values.
- Games: dice beyond six sides, loot rolls, spawn points, or board game tie-breakers.
- Lottery-style picks: draw 6 unique numbers from 1–49 (or any format your local lottery uses) with the no-repeat mode.
- Sampling: pick random row numbers for spot checks, audits, or survey sampling.
How the Randomness Works
Every draw maps a fresh random value onto your range so that each integer — including both endpoints — has exactly the same chance of being selected. Draws are independent: a number that just appeared is exactly as likely (or unlikely) to appear again on the next draw, unless you enable no-repeat mode, which removes drawn numbers from the pool within a single draw.
For picking between named options rather than numbers, our decision wheel is the better fit; for a simple binary choice, the coin flip settles it fastest.
