Dice Roller (d6, d20, d100)

Roll virtual dice fairly with cryptographic randomness. d6, d20, and d100 supported. Free, no signup, perfect for D&D, board games, and stats homework.

A dice roller picks a uniformly random integer from 1 to N (where N is the dice's number of sides). NamesOnWheel handles d6, d20, and d100 with crypto.getRandomValues + rejection sampling — provably fair, with each face exactly 1/N probable. Use the Quick Presets dropdown to swap dice types in one tap. Verifiable on /fairness.

Preset: d6

Auto-spin

Pick winner(s)

Tip: click a name to rename it · drag to reorder · tap N× to cycle chances · right-click the color dot to reset it.

How to use this picker

1

Pick your dice type

Open Quick Presets and choose Dice (d6) or Dice (d20). For d100, paste 1-100 manually.
2

Tap Spin

The wheel renders the faces and the spin lands on a uniformly random one.
3

Roll multiple dice at once

Set 'Pick N winner(s)' to e.g. 4 to roll 4d6 in a single spin sequence. Sum the results yourself or copy the list.

Frequently asked questions

How is this different from rolling physical dice?

Statistically, no difference if both are fair. Practically: virtual dice are auditable (you can verify our randomness on /fairness), faster, and impossible to lose under the couch. Physical dice can be subtly biased (manufacturing tolerance, table-tilt) — virtual cryptographic dice are not.

Can I do advantage / disadvantage rolls (D&D)?

Yes. For advantage: spin twice with d20 entries, take the higher. For disadvantage: take the lower. We don't auto-compute advantage because rule variants differ across systems.

How do I roll 3d6+5?

Set 'Pick N winner(s)' to 3, copy the three results, sum them, add 5. We chose not to bake math operators into the wheel because the visual spin loses meaning when there's a hidden formula.

Is the d100 wheel really fair?

Yes — same algorithm as every other wheel. 100 segments, 1% per face, rejection sampling means no modulo bias.

Can I add custom dice (e.g. d12 of monster types)?

Yes. Replace the entries with whatever 12 strings you want. The wheel doesn't care that they're not numbers.

Will my dice setup save?

Yes — last wheel persists in your browser via localStorage.
