How to Use the Dice Roller — Free Online Tool
How to use a free online dice roller to roll any dice — d4 to d20 and more — for board games, RPGs, and decisions when you have no dice.
Lost dice are the universal tabletop emergency. An online dice roller means you can always roll — any number of dice, any number of sides — straight from your phone or laptop, with results as fair as physical dice.
What is the Dice Roller?
An online dice roller simulates rolling dice of any type — the classic six-sided die, or RPG dice like d4, d8, d12, and d20 — and shows the result instantly. You can roll one die or several at once and read the total. It is completely free, runs entirely in your browser, and needs no signup — every result appears instantly and nothing you enter is sent to a server.
Because each roll uses your device's randomness, the results are unbiased — no weighted die, no favourite number creeping in. That fairness, plus the ability to roll any combination of dice on demand, makes a digital roller handy not just for games but for any moment you need an impartial result and have no dice in reach.
How to use the Dice Roller
Getting a result takes only a few seconds:
- Choose the type of die — d6 for board games, d20 for RPGs, and so on.
- Set how many dice to roll if you need more than one.
- Click Roll to get your result.
- Read the individual dice and the total.
- Roll again for the next turn.
Open the Dice Roller and try it now — generate as many times as you like until something fits.
Common use cases
A dice roller covers every roll you need:
- Tabletop RPGs like D&D that use d4 through d20
- Board games when the dice have gone missing
- Classroom probability and maths activities
- Quick, fair decisions when you cannot choose
- Drinking and party games
- Game design and playtesting
Tips for better results
- For RPGs, roll all the dice of one type together to save time on big rolls.
- Use the total for damage and checks; read individual dice when the game needs them.
- Bookmark the roller so it is one tap away at game night.

Can I roll several dice at once?
Set the count and roll a handful together, then read the total — exactly what you need for damage rolls, stat generation, and multi-die checks.
