Transparency

Randomness Audit

We believe fair randomness should be transparent. Here is exactly how Wheel Spiner selects a winner.

Our method

• Selection first, animation second. The winner is chosen before the wheel spins.
• Server-side: PHP random_int(), a cryptographically secure generator.
• Client-side fallback: the browser Web Crypto API (crypto.getRandomValues).
• Weighted mode: each entry's weight proportionally increases its chance.
• Algorithm version: spinpick-rng-1.0.0

Wheel Spiner does not claim third-party randomness certification.
