✦ The prize booth · every name gets a fair shot
Fair picker
Paste names, import CSV data or a public Google Sheet, keep repeated entries, and assign transparent weights. Every row stays in the draw, including repeats. Randomize Fun selects with cryptographic rejection sampling and creates a downloadable audit certificate containing the exact committed entries, weights, result, and proof digest.

One per line. Add an optional weight after “|”, for example: Avery | 3
6 total entries · 6 unique entries (case-insensitive) · Repeats included
✦ Proof booth
Fairness & entropy audit
Each proof commits the entries, weights, random bytes, result, timestamp, nonce, and previous proof digest. Recomputing SHA-256 detects later changes; it does not prove that a dishonest host committed the inputs before drawing.
