A Fair Roll, Every Time
Physical dice are wonderful, but they get lost, they fall off the table, and not everyone carries a full set of polyhedrals. A virtual dice roller solves all of that: it is always to hand on your phone or laptop, rolls any dice you need, and adds up the total instantly. Because each die uses your browser's random number generator, every face has an equal chance and the results are genuinely fair — arguably fairer than a real die, which can be subtly weighted or biased by wear.
Understanding Dice Notation
Tabletop games use a shorthand for dice you will see everywhere: a number, the letter “d”, and the number of sides. So 2d6 means “roll two six-sided dice and add them”, and 1d20 means “roll a single twenty-sided die”. Damage in a role-playing game might be listed as 3d8, an ability check as 1d20, and a simple board game move as 2d6. This roller lets you set the count and the die type to match any such notation and totals the result for you.
Which Dice for Which Game?
Most classic board games use one or two D6 dice — the familiar cube with pips. Role-playing games use the whole polyhedral set: the D20 is the star, used for attack rolls and skill checks, while the D4, D8, D10, and D12 typically handle weapon and spell damage. The D10 is also used in pairs to generate percentages. Whatever your game calls for, you can set it up here in a couple of taps.
Dice Roller Tips
Match the notation
For "3d6", set 3 dice and D6. The tool rolls all three and adds them for you.
D20 for checks
Role-playing checks and attacks usually use a single D20. Set 1 die and D20.
Percentile with two D10
Roll two D10 to simulate a percentage roll (00–99) common in many RPG systems.
Board games love D6
Most family board games use one or two six-sided dice — the classic pip faces are shown for D6.

Frequently Asked Questions
How does the online dice roller work?
Choose how many dice you want to roll (from one to six) and how many sides each die has (D4, D6, D8, D10, D12, or D20), then press Roll. The dice tumble briefly and settle on a random result, and the tool adds up the total for you. Each die is rolled independently using your browser’s random number generator, so every result is fair.
Are the dice rolls truly random?
Yes. Each die uses your browser’s built-in random number generator, giving every face an equal chance on every roll. The rolls are independent, so previous results have no effect on the next one — exactly like fair physical dice. The tumbling animation is purely for effect and does not influence the outcome.
What dice types are supported?
The roller supports the full set of standard polyhedral dice used in tabletop games: D4 (four-sided), D6 (the classic cube), D8, D10, D12, and D20. The six-sided dice show traditional pip faces, while the others show their numeric value. You can roll up to six dice of the same type at once and see the combined total.
Can I roll multiple dice at once?
Yes. Select from one to six dice and they all roll together, with each result shown separately and the total calculated automatically — so "3d6" rolls three six-sided dice and sums them. This is ideal for board games and role-playing games where you often roll several dice and add them up.
Is this good for D&D and tabletop RPGs?
Absolutely. Role-playing games like Dungeons & Dragons rely on polyhedral dice — the D20 for checks and attacks, and combinations like 2d6 or 3d8 for damage. This roller covers all the standard dice, rolls several at once, and totals them instantly, so it is a handy replacement when you do not have your physical set to hand.
Is it free and does it work on mobile?
Yes. The dice roller is completely free with no signup and no ads, and it runs entirely in your browser, so it works offline once loaded. The buttons are large and touch-friendly, making it easy to roll on a phone or tablet at the game table.
