Online Dice Roller

Roll any dice — d4 to d100, multiples at once, fair rolls.

# dice

🎲 Rolls come from crypto-grade randomness with rejection sampling — no modulo bias, no predictable sequences. Up to 20 dice per roll.

Which dice for which game

D6 covers mainstream board games; D20 drives Dungeons & Dragons attack and save rolls; percentile D100 resolves percentage tables in Call of Cthulhu and Warhammer. The roller supports all of them plus d4/d8/d10/d12.

Reading multiple dice

Rolling 2d6 produces two independent results summed — crucial because 2d6 (bell-curved toward 7) plays very differently from 1d12 even though both max at 12. Each die is shown individually above the total.

Fairness you can trust

Physical dice wear unevenly and casino-grade balanced dice cost real money. This roller draws from crypto.getRandomValues with rejection sampling, so every face is equally likely likely by construction.

Frequently Asked Questions

Are the dice rolls actually random?

Yes — the tool uses the browser's crypto.getRandomValues(), the same cryptographic randomness used for secure keys, not the older Math.random(). Each die is rolled independently, so a d20 has an exactly even 5% chance per face.

Can I roll multiple dice at once, like 3d6+2?

Yes. Pick the die type (d4, d6, d8, d10, d12, d20, or d100), set how many dice to roll, and add a flat modifier if your game uses one. You see each individual die result plus the total, so a DM or player can verify every roll.

Does it work for tabletop RPGs like D&D?

That's the main use case: d20 attack and saving throws, 4d6 drop-low ability score rolling, percentile d100 checks, and everything in between. Nothing is stored or sent anywhere — it is a pure in-browser roller, so it also works offline.

Why do I get the same numbers often — is it rigged?

Randomness is clumpy: in 20 rolls of a d6, seeing a 4 three times is statistically normal. Over hundreds of rolls the counts converge toward even. The tally mode lets you verify this yourself across a session.
