About this tool
Pick random whole or decimal numbers in any range — one or thousands, with or without repeats, sorted or not — for draws, games, sampling and tests.
Whole numbers use rejection sampling on 32-bit random values, so every number in the range is exactly equally likely; “no repeats” draws until each value is new.
Example: 6 numbers from 1 to 49 without repeats, sorted.
Values come from the browser’s cryptographic random generator (unbiased, not predictable). With a seed the sequence is repeatable and must not be used for anything secret.
