Dice Roller
Pick a die, set how many to roll, then press Roll for an instant, fair result. Add a modifier, or roll with advantage or disadvantage on a d20. Every face has exactly the same chance.
How to use the dice roller
- Choose a die. Tap d4 through d100, or type a custom number of sides for anything else.
- Set how many dice. Roll up to 20 at once. Each die is shown separately, plus the total.
- Add a modifier if needed. A tabletop roll like 1d20+5 becomes: 1 die, d20, modifier 5.
- Roll. Press the button or the Space bar. Advantage and disadvantage apply only when you're rolling a single d20.
Every total for two six-sided dice
Two d6 give 36 equally likely combinations. Some totals, like 7, come up in more ways than others, which is why 7 is the most common result.
| Total | Ways to make it | Chance |
|---|---|---|
| 2 or 12 | 1 | 2.78% |
| 3 or 11 | 2 | 5.56% |
| 4 or 10 | 3 | 8.33% |
| 5 or 9 | 4 | 11.11% |
| 6 or 8 | 5 | 13.89% |
| 7 | 6 | 16.67% |
This table is for 2d6 specifically. A custom die or a different number of dice changes the odds.

Tips for rolling dice online
Advantage and disadvantage only affect a single d20. They model the tabletop rule of rolling twice and keeping one result, so they're switched off automatically for any other die or dice count.
A modifier applies once, to the total. For 3d6+2, the generator adds 3 dice together, then adds 2 to that sum, the same way it works at the table.
Keep your roll log open during a session. It lists your last 20 rolls, which is handy if a player at the table asks what you just rolled.
Why these rolls are fair
Every roll starts from crypto.getRandomValues, the random source browsers use for encryption, then goes through rejection sampling so each face of the die has an exactly equal chance. There's no weighting toward high or low numbers, and no way to influence a roll by clicking faster or slower.
Rolls happen on your device and are never sent anywhere.

Dice roller questions
What dice can I roll?
d4, d6, d8, d10, d12, d20 and d100. You can also set a custom die with any number of sides.
How do I roll 2d6?
Set the count to 2 and the die to d6, then press Roll. You'll see each die and the total.
Can I add a modifier like +3?
Yes. Enter a modifier and it's added to the total, so 1d20+3 works just like it does at the table.
Does it support advantage and disadvantage?
Yes. Roll with advantage or disadvantage and the tool rolls two d20s, shows both, and highlights the one that counts.
Are the dice fair?
Yes. Every face has an exactly equal chance on every roll. Digital dice have no weighting, chipped edges or lucky throwing style.
What's the most common total with two dice?
Seven. There are six ways to make 7 with two six-sided dice, out of 36 combinations, which gives a 1 in 6 chance.
Can I roll dice for board games like Monopoly or Catan?
Yes. Select 2d6 and keep the page open next to the board. The Space bar rolls again quickly.
Can I see my previous rolls?
Yes. The roll log lists your last 20 rolls with their totals, so everyone at the table can check.
