Decision wheel
Add your options, spin in 3D, and share the proof that the result was fair.

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.

Your quick guide to the wheel
- Enter choices one per line, or enable comma splitting. Review total and unique counts; repeated entries keep separate slots.
- Choose Spin fairly for a cryptographic result. For movement-driven fun instead, switch to Gesture Playground.
- Use the audit panel to verify or download a fair draw. Choose Host room in fair mode to invite a read-only audience.
Evidence, not promises
How to prove this random generator is unbiased
Randomize Fun uses rejection sampling over the browser's cryptographic random source, commits the complete draw configuration to a versioned SHA-256 proof, and reports distribution statistics without treating small samples as conclusive. Anyone with the audit payload can recompute its hash and detect whether the saved entries, result, or metadata changed.
