Randomness Audit

Test a weighted wheel against its expected probabilities, inspect browser random source status, and copy a plain-language audit report. You can configure entries and weights on our custom random picker wheel to run giveaways, classroom picks, team drawings, and other public decisions.

🔒 Random source

SpinWheelify uses crypto.getRandomValues through a small secureRandom utility. Browser vendors seed this generator from platform entropy sources.

⚖ Weighted probability

For weighted choices, the random float is scaled to the total sum of all weights, and we iteratively find the target.
