Random Winner Picker

How the random winner picker works

Picking a winner fairly means giving every entry exactly the same chance — and doing it in a way nobody can dispute. This tool assigns each entry a position in a list, then draws using a cryptographically secure random number generator in your browser, seeded with entropy from your operating system. Because the draw happens locally and uses an unbiased source, each entry's probability is identical: with 250 entries, every single one has a 1÷250 = 0.4% chance on a single-winner draw.

The method, step by step

1. Enter the contestants — paste names, ticket numbers, or comment handles, one per line. 2. Set the number of winners. 3. Draw without replacement. The tool shuffles the full entry list with the Fisher–Yates method and takes the first N names. “Without replacement” means each drawn entry is removed from the pool, so the same person cannot win twice — the correct behaviour for prize draws.

Worked example: 3 winners from 250 entries

After shuffling, the first three entries might be #148, #22, and #207. Each entry had a 3÷250 = 1.2% chance of being among the winners, and every possible trio was equally likely. Notice what the tool does not do: it never re-rolls a result because someone dislikes it. Re-drawing until a preferred outcome appears is selection bias — it quietly converts a fair draw into a rigged one.

Practical tips and limits

For a defensible public draw: announce the entry list and the number of winners before drawing, draw exactly once, and keep a screenshot or recording showing the entries, the settings, and the result with a timestamp. One honest limitation: the tool cannot verify that your entry list is complete or free of duplicates — clean the list first (one line per real entry), because the draw is only as fair as the list it draws from.
