Two dice, both faces and the total
Each roll throws two six-sided dice by default and shows you the face on each die and their total between 2 and 12. When a game needs something else, switch to d4, d8, d10, d12, d20 or d100, roll up to ten dice and add a modifier.
Two d6 is the pair almost every board game in a cupboard asks for — Monopoly, backgammon, Catan, Snakes and Ladders. When the dice have gone missing under the sofa, this replaces them without changing the odds of the game.
Each die is rolled independently from the browser's cryptographic random source, with biased values discarded. The faces are not derived from the total, so the pair you see is the pair that was rolled.
Roll and read the result
Two six-sided dice are ready by default. Change the die, the number of dice or the modifier in the side panel when your game asks for it.
Press roll to throw both dice at once.
Read the two faces if your game moves pieces per die, or the total if it moves per sum.
Roll again for the next turn; each roll is independent of the last one.
What the roller shows you
The display is built around the two numbers games actually use.
- Both individual faces, each from 1 to 6
- The combined total, from 2 to 12
- Independent rolls, with no carry-over from the previous throw
- A shared link so a remote opponent sees the same roll you do
- No setup, no sign-in and nothing to install before the first roll
- d4, d6, d8, d10, d12, d20 and d100, up to ten dice and a modifier
Board games, backgammon and probability lessons
Two dice cover more table situations than any other combination.
A family plays Monopoly with the dice missing and moves by the displayed total.
Two players run a backgammon game using the two faces separately rather than the sum.
A maths teacher records thirty totals and the class compares how often 7 appears against 2.
A pub quiz host uses the first die to pick one of six categories, ignoring the second die.
A role-playing group makes a 2d6 check for a rules-light system.
A remote pair shares a roll link so neither side has to trust the other's dice.
Why 7 comes up most often
Two dice produce 36 equally likely face combinations, but only 11 possible totals, so the totals are not equally likely. Seven has six combinations behind it (1+6, 2+5, 3+4 and their mirrors), which is why it lands roughly once every six rolls. Two and twelve have one combination each, so each appears about once in 36 rolls.
The full distribution is worth knowing if you are teaching it or arguing about it: 2 and 12 at 1 in 36 each, 3 and 11 at 2 in 36, 4 and 10 at 3 in 36, 5 and 9 at 4 in 36, 6 and 8 at 5 in 36, and 7 at 6 in 36. A small sample of rolls will not necessarily match these proportions.
An individual die is different: each of its six faces is equally likely on every roll, and a run of sixes does not make the next six less likely.
What this roller does not do
Shared rooms by link always roll two six-sided dice. Other dice, more dice and modifiers work on this page only.
There are no advantage, exploding-dice or reroll rules: the roller adds up the dice and the modifier and leaves the rules to you.
It is not a gambling device and keeps no certified record of rolls.
Using the roller at a real table
- Agree before you start whether your game uses the two faces or the total — it changes doubles handling in games like backgammon.
- For a maths exercise, have pupils predict the distribution before rolling thirty times, then compare against the probabilities above.
- Share a link for a remote game so both players read the same roll instead of reporting it to each other.
- For a role-playing check, set the roll once, for example 1d20+5; the total shown already includes the modifier.
Dice questions
Are all totals equally likely?
No. Seven is the most likely total, at 6 chances in 36, because six different face pairs add up to it. Two and twelve are the least likely at 1 in 36 each, since only double-one and double-six produce them.
What is the chance of rolling a 7?
Six of the 36 possible combinations total seven, so roughly 16.7% — about one roll in six. Six and eight are next at 5 in 36, or about 13.9% each.
Can I roll a d20 or a single die?
Yes. Choose d4, d6, d8, d10, d12, d20 or d100 in the side panel, set from one to ten dice and add a modifier if your rules call for one, for example 1d20+5.
How many dice does it roll?
Two six-sided dice by default, so the total falls between 2 and 12. In the side panel you can roll from one to ten dice of any supported type.
Is the roller genuinely random?
Yes. Each die draws from the browser's cryptographic random source, and values that would bias the faces are discarded rather than reused. Each die is rolled independently of the other.
Does a run of sixes make the next six less likely?
No. Every roll is independent, so a streak changes nothing about what comes next. That expectation is the gambler's fallacy, and dice do not work that way.
Can my opponent see the same roll?
Yes, through a shared link. Both sides then read one roll instead of each rolling separately and reporting the result.
Should I use dice or a random number generator?
Use the dice when you want real 2d6 odds, where 7 is common and 12 is rare. Use the number generator when every value in your range should be equally likely.
