Dice Roller
Roll d4, d6, d8, d10, d12, d20 and d100 — single dice or any combination, with each result shown.
Quick answer
What is the Dice Roller?
Roll any dice you need without digging through a dice bag. Tap the plus button on each die to build your roll, then roll them all at once and see every individual result along with the total. The current result stays visible until you roll again, so everyone at the table can check it.
How to Use the Dice Roller
- Tap + on any die type to add it to your roll, and − to remove one.
- Combine different dice freely, for example one d20 plus two d6.
- Press the Roll button to roll everything you have selected.
- Read each die's result on its own tile; the combined total appears underneath.
- If you already know dice notation, open Advanced and type an expression like 2d6+1d4.
What You Can Use It For
- Tabletop RPGs including Dungeons & Dragons, Pathfinder and Call of Cthulhu
- Board games where dice have been lost from the box
- Warhammer and other miniature wargames needing many dice at once
- Random number generation for teaching probability
- Yahtzee, Farkle and other dice games
Tips for Using the Dice Roller
- Build the full roll before tapping Roll so every die uses the same throw.
- Read the individual die results as well as the total when the whole table needs to verify a roll.
- For a physical-feeling decision, roll several dice and use the individual results rather than only the total.
What does d20 or 2d6 mean?
The letter d stands for die, and the number after it is how many sides that die has. So d20 is a twenty-sided die producing a number from 1 to 20. A number in front means how many of that die to roll, so 2d6 means roll two six-sided dice and add them together. You never have to type this notation here, but it is shown so you can learn it.
Are the results genuinely random?
Each die is rolled independently with the site's random-number helper. Browsers with Web Crypto support use a secure random source with rejection sampling; older environments use a compatibility fallback. Maximum rolls are highlighted in green and natural ones in red so critical results are easy to spot at a glance in role-playing games.
Rolling large handfuls of dice
You can add up to twenty of a single die type and thirty dice in total, which covers wargame volleys and other bulk rolls. Every die is displayed separately rather than only as a sum, so you can count successes against a target number instead of just reading the total.
Frequently Asked Questions
What dice types are supported?
d4, d6, d8, d10, d12, d20 and d100. You can add several of each and roll different types together in a single throw.
Do I need to know dice notation like 2d6?
No. Tap the plus button on each die to build your roll visually. Dice notation is still available under the Advanced panel if you prefer typing it.
What does d20 or 2d6 actually mean?
The d stands for die and the number after it is how many sides it has, so a d20 gives a result from 1 to 20. A number in front is how many to roll, so 2d6 means roll two six-sided dice and add them together.
Are the dice rolls truly random?
Yes. Each die is rolled independently with the site's random-number helper. Browsers with Web Crypto support use a secure random source with a compatibility fallback for older environments.
What do the coloured dice results mean?
Green marks a maximum roll on that die and red marks a natural 1, which makes critical successes and failures easy to spot in role-playing games.
Does Dice Roller save a roll history?
No. The current roll and its individual results stay visible until you roll again, but roll history is not saved after a page reload.
