Standard Dice Types
| Die | Faces | Common Use |

Cryptographic Randomness
All rolls use crypto.getRandomValues() — the same secure random number generator used for cryptographic applications. Results are statistically uniform with no bias toward any particular face.

Beyond D&D — Other Uses for Dice
Dice rollers are useful well beyond tabletop RPGs. Board games like Monopoly and Catan use multiple D6s. Wargames like Warhammer use D6 and D10 for hit and wound rolls. Yahtzee requires rolling five D6s simultaneously. Teachers use dice for maths exercises and probability demonstrations. Game designers prototype mechanics before physical dice are manufactured. This online roller works for all of these — no physical dice required.
