How to Roll Dice Online for Free (2026 Guide)

The dice rolled under the sofa again. Or you're playing a game that needs a 20-sided die you don't own. An online dice roller solves both problems: it simulates any number of dice with any number of sides, instantly, on any device. This guide shows you how to roll dice online for free, step by step — from a basic board-game roll to the exotic dice of tabletop RPGs.

Step-by-step: roll dice with our free tool

Our Dice Roller runs entirely in your browser — no signup, no app install. Here's how to use it:

1. Open the Dice Roller. You'll see two settings: "Dice" (how many dice to roll) and "Sides" (how many sides each die has).
2. Set the number of dice — anything from 1 to 10. Playing a game that needs two dice? Enter 2.
3. Set the number of sides — anything from 2 to 100. Standard board games use 6; RPGs use 4, 8, 10, 12, 20 or even 100.
4. Click "🎲 Roll". The result shows each die's value and the total, e.g. "🎲 4 • 6 = 10".
5. Roll again as many times as you need — it's unlimited.

Dice notation: reading "2d6" and "1d20"

Gamers write dice rolls in a shorthand you'll see in rulebooks: NdS means "roll N dice with S sides each." So:

• 1d6 = one 6-sided die (set Dice: 1, Sides: 6)
• 2d6 = two 6-sided dice, added together (set Dice: 2, Sides: 6)
• 1d20 = one 20-sided die (set Dice: 1, Sides: 20)
• 1d100 = percentile roll, 1–100 (set Dice: 1, Sides: 100)

Our tool shows both the individual dice and their sum, which covers the vast majority of game rules.

Real use cases

• Board games with lost dice: The classic emergency. Set 1d6 (or 2d6 for games like Monopoly or Backgammon) and play on.
• Tabletop RPGs (D&D, Pathfinder): Roll 1d20 for attacks and skill checks, 1d8 or 1d12 for damage, 1d100 for percentile tables — no physical dice set required.
• Party and drinking games: Roll on a shared screen so everyone sees the result at once.
• Classroom probability: Roll 2d6 thirty times and chart the totals — students discover the bell curve themselves (7 is the most common total).
• Decision making: Choosing among up to 100 options? Number them, set Sides to the count, roll 1 die. More flexible than a coin flip when you have more than two choices.
• Remote / video-call games: Share your screen and roll for the whole group — everyone trusts what they can see.

Practical example: a board game night

You're playing a game that needs 2d6 for movement. Open the roller, set Dice: 2, Sides: 6, and click Roll. The display shows something like "🎲 3 • 5 = 8" — move 8 spaces. Next player's turn? Click Roll again. It takes about two seconds per roll, and there's no die to chase across the room.

Practical example: an RPG attack roll

Your character swings a sword: the rules say roll 1d20 to hit, then 1d8 for damage. First set Dice: 1, Sides: 20 and roll — say you get 17, a hit. Then change Sides to 8, roll again — 6 damage. Two clicks, no dice bag needed.

How fair are virtual dice?

An honest note: the tool uses your browser's standard pseudo-random generator, giving each face an equal probability — a fair die for games, parties and teaching. Physical dice can actually be less fair (worn edges, imperfect balance, sloppy throws). The one thing virtual dice aren't for: real-money gambling or anything requiring certified randomness — regulated games need audited random number generators, which a free web tool doesn't claim to be.

Tips for smooth play

• Set it once per game phase. If a game uses 2d6 all evening, leave the settings alone and just hit Roll each turn.
• Read the total, but check the dice. Some rules care about doubles (two matching dice) — the display shows individual values for exactly this reason.
• For percentile (1d100): set Sides to 100. A result of 1–100 maps directly to percentage tables in many RPGs.
• Combine with the Random Number Generator when you need many results at once (up to 1,000) or unique numbers with no repeats.

Frequently asked questions

Is the dice roller really free?

Yes — 100% free, unlimited rolls, no signup. It works on phones, tablets and computers, online in your browser.

Can I roll more than 10 dice?

The tool supports up to 10 dice per roll with up to 100 sides each. If you need hundreds of results at once, the Random Number Generator can produce up to 1,000 numbers in one click.

Why did I get the same number twice in a row?

That's normal randomness — each roll is independent, so repeats happen. (Rolling two sixes in a row has a 1-in-36 chance: uncommon, not impossible.)

Can I use it for D&D?

Absolutely — it covers every standard die: d4, d6, d8, d10, d12, d20 and d100. Set the sides to match and roll.
