Frequently Asked Questions

Is this dice roller truly random?→

Yes. The roller uses the Web Crypto API (window.crypto.getRandomValues), which provides cryptographically secure pseudo-random numbers. Unlike Math.random(), this draws from your operating system's hardware entropy sources, producing genuinely unpredictable results suitable for fair gaming.

What dice types are supported?→

All standard polyhedral dice: d4 (tetrahedron), d6 (cube), d8 (octahedron), d10 (pentagonal trapezohedron), d12 (dodecahedron), d20 (icosahedron), and d100 (percentile). You can roll 1 to 20 dice simultaneously.

Can I use this for Dungeons & Dragons?→

Absolutely. Roll d20 for attack rolls and saving throws, d6/d8/d10/d12 for damage, and d100 for percentile checks. The history feature helps track rolls during combat encounters.

Is the roll history saved between sessions?→

No, the roll history is stored in memory and clears when you close the page. This ensures privacy - no dice roll data is stored permanently or sent to any server.
