Optional. Commas between values, dashes for ranges.
About random numbers from 1 to 50
This generator picks a random whole number between 1 and 50, inclusive, with every value equally likely at 1 in 50 (2%). It is a handy size for medium groups and lists: drawing a winner from 50 raffle tickets, choosing one of the 50 US states for a geography quiz, selecting a random page from a 50-page workbook, or assigning seats in a room of fifty.
If you need several numbers, switch to Multiple numbers. With “No duplicates” on you can, for example, pick 5 unique winners from 50 entries, or generate a lottery-style line of 6 different numbers. Leave duplicates allowed when each draw should be fully independent, such as simulating repeated trials.
Duplicates are more common than intuition suggests: by the 9th independent draw there is already about a 54% chance that one number has repeated. When fairness matters — prize draws, rotating chores, or calling on participants — use Draw mode. It works like pulling numbered tickets from a hat: every number from 1 to 50 comes out exactly once, the remaining count updates after each draw, and Reset puts all fifty tickets back.
Frequently Asked Questions
What are the odds of picking a specific number between 1 and 50?↓
2% (1 in 50) on each independent draw. In Draw mode the odds improve as numbers are removed — with 10 numbers left, each remaining one has a 10% chance.
Can I pick multiple unique numbers from 1 to 50?↓
Yes. Choose Multiple numbers, set Min 1, Max 50 and your Count, then switch on “No duplicates” to get a list with no repeated values.
Is this fair enough for a raffle?↓
Yes. Numbers are produced with crypto.getRandomValues() using rejection sampling, so every value is equally likely. Draw mode ensures no ticket is drawn twice.
