Dice Roller
Roll up to six dice — d4, d6, d8, d10, d12 or d20 — and see the total.
How to use the dice roller
Choose how many dice and how many sides.
Press Roll (or the Space bar).
See each die and the total. Recent rolls are listed below.
How the dice roller works
Choose how many dice (1 to 6) and how many sides each die has, then press Roll. You'll see each die and the total. Every face has the same chance: 1 in 6 on a d6, 1 in 20 on a d20.
Wheelova uses your browser's crypto.getRandomValues(). According to MDN, browsers implement it as a cryptographically secure pseudo-random generator seeded with system entropy — the same kind of source used for security features. It is unpredictable in practice, but it is not a physical "true random" device such as atmospheric-noise generators.
Which dice can I roll?
| Die | Sides | Chance of each face | Common uses |
|---|---|---|---|
| d4 | 4 | 25% | Tabletop RPG damage |
| d6 | 6 | 16.7% | Board games, Yahtzee, Monopoly |
| d8 | 8 | 12.5% | RPG damage rolls |
| d10 | 10 | 10% | Percentile rolls, RPGs |
| d12 | 12 | 8.3% | RPG damage, maths games |
| d20 | 20 | 5% | Dungeons & Dragons checks and attacks |
Two dice: why 7 comes up most
With one die, every number is equally likely. With two dice added together, they aren't — there are more ways to make 7 than any other total:
| Total | Ways to roll it | Chance |
|---|---|---|
| 2 or 12 | 1 | 2.8% |
| 3 or 11 | 2 | 5.6% |
| 4 or 10 | 3 | 8.3% |
| 5 or 9 | 4 | 11.1% |
| 6 or 8 | 5 | 13.9% |
| 7 | 6 | 16.7% |
That's why 7 matters so much in games like Catan and craps. The dice roller adds the total for you, so it works for any game that uses sums.
Ideas
Board games: replace lost dice, or roll for a game that needs more dice than you have.
Tabletop RPGs: quick d20 checks or damage rolls when you're away from your dice bag.
Maths lessons: roll two dice 50 times, record the totals and compare with the table above.
Decisions: number your options 1–6 and roll. For more than six options, use the Online Spinner.
Questions
How many dice can I roll at once?
Up to six dice of the same type per roll.
Can I roll a d20?
Yes. Choose 20 sides. Each face has a 1 in 20 (5%) chance.
Is the virtual dice roller fair?
Yes. Every face has the same chance, chosen by your browser's cryptographically secure random generator, and each roll is independent.
What's the most likely total with two dice?
7, with a 1 in 6 (16.7%) chance. 2 and 12 are least likely, at 1 in 36 each.
Can I use it for Dungeons & Dragons?
Yes for single-type rolls like 1d20 or 3d6. For mixed rolls such as 1d8+1d6, roll each type separately.
