Generate random numbers in any range — instantly
This tool uses JavaScript's Math.random() function, which returns a value between 0 and 1. That value is scaled to your chosen range so every whole number between your minimum and maximum has an equal chance of being picked. Each generation is independent of the last.
Random numbers are handy for raffles and giveaways, picking lottery-style numbers, assigning turns or teams, choosing a winner from a numbered list, games, statistical sampling, and any time you need a fair, unbiased pick.
Set "How many" above 1 to draw several numbers at once. Tick "No duplicates" to make every number unique — useful for draws where the same number shouldn't repeat. Note that when duplicates are off, you can't request more numbers than the range contains.
Like most browser tools, this generator is pseudo-random: the results are unpredictable and evenly distributed for everyday use, but they're produced by a mathematical algorithm rather than a physical source of randomness. For casual decisions, games, and draws it's effectively random.
