What is a random number between 1 and 50?

Each of the 50 integers from 1 to 50 has a 2% chance of being selected on every generate. The 1–50 range hits the sweet spot between small group tools and full 1–100 generators: it covers class rosters of 30–50, half-century raffles, and percentage-style games where you need a finer range than 1–20 but don't need the full 1–100 spread.

Pool mode for mid-size raffles

Pool mode uses the Fisher-Yates shuffle to draw each of the 50 numbers exactly once before any repeat occurs. This makes it ideal for assigning unique raffle ticket numbers, calling on students in a class of up to 50, or running ordered draws where every participant must be reached before cycling again.

Distribution: buckets of 5

After 10 generates the distribution chart appears, grouping results into 10 buckets of 5 numbers each (1–5, 6–10, … 46–50). Over many generates, each bucket should fill at roughly the same rate, confirming uniform randomness across the full 1–50 range.

Frequently asked questions

Is this random number generator truly random?
Yes — it uses Math.random(), seeded from hardware entropy in your browser. The output passes standard statistical randomness tests, making it suitable for games, raffles, and classroom sampling.
What is pool mode?
Pool mode picks each number from 1 to 50 exactly once before any repeat. It uses the Fisher-Yates shuffle for fairness. Once all 50 have been drawn, the pool resets automatically.
Can I exclude specific numbers?
Yes. Click "Exclude numbers" and enter a comma-separated list. Excluded numbers are skipped in both normal and pool modes.
How is this different from the 1–100 generator?
This page is optimized for the 1–50 range. Pool mode tracks 50 numbers, distribution groups into buckets of 5, and all range references match 1–50. For a larger range, see the 1–100 generator.
