How to use the online dice roller

This guide walks through everything the dice roller can do, from a single click for a board game to longer rolls for role-playing games. You do not need an account and nothing has to be installed: the roller runs in any modern browser on a phone, tablet or computer.

1. Roll a single six-sided die

Open the home page and press the orange Roll the Dice! button. The box above the button already says 1d6, which means “one six-sided die”, so you get a number from 1 to 6. The die picture shakes briefly and then shows the face you rolled. The total is also printed in large numbers underneath, so you can read it from across the table.

Press the button again for the next roll. There is no waiting time and no limit on how many times you can roll.

2. Use the quick dice buttons

Below the input box is a row of buttons for the most common rolls:

1d6, 2d6 and 5d6 – one, two or five ordinary dice, for family games such as Monopoly, backgammon or Yatzy.
d4, d8, d10, d12 and d20 – the polyhedral dice used in role-playing games.
d100 – a percentile roll from 1 to 100.
d20 advantage – rolls two twenty-sided dice and keeps the higher one.

Pressing a quick button copies its notation into the box and rolls immediately. After that, the big Roll the Dice! button repeats the same kind of roll, which is handy when you need the same dice over and over.

3. Type your own roll with dice notation

You can type any roll into the box and press Roll the Dice! or the Enter key. The roller understands standard dice notation:

Supported dice notation
You type	Meaning
`d20` or `1d20`	One twenty-sided die. If you leave out the number of dice, the roller assumes one.
`3d6`	Three six-sided dice, added together.
`2d6+3`	Two six-sided dice plus a modifier of 3.
`1d20-2`	One d20 minus 2. Results can go below 1 when the modifier is negative.
`1d8+2d6+4`	Different dice in one roll: a d8, two d6 and a bonus of 4, all added together.
`d%` or `1d100`	A percentile roll from 1 to 100.
`4d6kh3`	Roll four d6 and keep the highest three. `4d6k3` means the same.
`2d20kl1`	Roll two d20 and keep the lowest one (disadvantage in D&D 5e).
`1d3`, `1d7`, `1d30`	Unusual dice work too: any number of sides from 2 to 1000.

Capital letters and spaces around + and - are ignored, so 2D6 + 3 works as well. Spaces anywhere else are not allowed: 1d20 5 is rejected instead of being read as a d205, so put a + or - between the parts. If the roller cannot understand what you typed, it shows a short message in red explaining what to change, and nothing is rolled.

4. Read the result

After each roll you see three things:

The dice themselves. Six-sided dice are drawn as dice pictures. Other dice are shown as tiles with the number on top and the die type (for example “d20”) underneath. Dice that were dropped by a “keep” rule are shown faded.
The total, in large type.
The breakdown, for example 2d6+3: [4, 6] + 3. Every die value is listed inside square brackets. Dropped dice are shown in round brackets, so 4d6kh3: [5, (2), 6, 4] means the 2 was dropped and the total is 5 + 6 + 4 = 15.

When more than 30 dice are rolled at once, only the first 30 are drawn to keep the page tidy, but every die is still counted in the total and listed in the breakdown.

5. Roll history, roll counter and sound

Your last eight rolls are listed under the result, newest first, so you can look back if someone missed a roll. Press Clear history to empty the list. The history disappears when you close or reload the page.

The roller also shows how many times you have rolled in total on this device. This number, and whether the rolling sound is switched on, are saved in your browser’s local storage. They are never sent to us. You can reset them by clearing the site data for onlinediceroller.com in your browser settings. Read more in the privacy policy.

Untick Sound if you want to roll quietly, for example in a classroom or late at night.

Tips for games and classrooms

Playing at the table? Put a phone or tablet in the middle so everyone can see the dice and the history. Nobody can argue about a roll that is listed on screen.
Need the same roll many times? Type it once, then just press Enter or the button for each new roll.
On a computer, press Tab to move between the box, the button and the quick buttons, and Enter to roll.
Teaching probability? Ask the class to predict which total of 2d6 will come up most often, then roll it 30 or 50 times and compare the tally with the table in the dice probability guide.
Choosing at random? Number your options and roll a die with that many sides, such as 1d5 for five choices.

Troubleshooting

I don’t hear the rolling sound.: Check that the Sound box is ticked and that your device is not muted. On some phones the silent switch also mutes web pages.
Nothing happens when I press the button.: The roller needs JavaScript. Make sure it is enabled in your browser. If you typed your own roll, look for a red message under the dice explaining what needs to change.
Why can’t I roll more than 100 dice?: The limit keeps the page fast on every device. If you need more, roll several times and add the totals.
