Frequently asked questions
Is this random number generator truly random?⌄
Uses crypto.getRandomValues() for cryptographically secure random numbers — far better than Math.random().
How does the dice roller work?⌄
Select RPG dice (D4–D100) and count. Each die gets independent random roll. D6 shows ⚀–⚅ Unicode dice faces.
Can I pick multiple winners without duplicates?⌄
Yes — list picker and lottery modes use Fisher-Yates shuffle, no duplicates. Every participant has equal chance at each position.
Is my data saved anywhere?⌄
No — all generation happens in your browser. Recent history is in sessionStorage and disappears when you close the tab. Nothing is sent to any server.
