D&D Dice Roller

What is the D&D Dice Roller?

The D&D Dice Roller is a dice tray for Dungeons & Dragons and other tabletop RPGs, with real 3D dice. Type a roll the way it is written in the rules, like 1d20+5 for an attack or 8d6 for a fireball, and the dice tumble onto the table and land. It understands the full dice notation players use, rolls with advantage or disadvantage, lights up a natural 20, keeps your character’s regular rolls one tap away, rolls a whole set of ability scores, and shows the odds of every roll.

The D&D Dice Roller: obsidian dice on crimson felt, the dice notation box, advantage buttons and saved attacks

Dice notation it understands

• 2d6+3: two six-sided dice plus 3. Mix dice freely: 1d8+1d6+4, 2d6-1d4.
• 4d6kh3: roll 4, keep the highest 3 (also kl, dh, dl to keep the lowest or drop dice).
• 2d20kh1 and 2d20kl1: advantage and disadvantage. The buttons do it for you.
• 3d6!: exploding dice. Each die that shows its top number is rolled again and added.
• 2d6r1: reroll ones until they are not ones; 2d6ro1 rerolls them once; 2d6ro<2 rerolls ones and twos once.
• d% or d100 for percentiles, 4dF for Fudge / FATE dice, and any size like d3.

Made for the table

• Saved rolls: keep your attacks, damage and spells as named buttons, like “Longsword 1d8+3”.
• Ability scores: one tap rolls 4d6 drop the lowest, six times, with each score’s modifier.
• Natural 20 and natural 1 glow gold or red on the table, with a sound.
• The odds of every roll: the chance of each total, your roll marked and how rare it was.
• A party table: open a room and send the link; everyone sees each throw land the same way, with who rolled it.
• Dice sets in obsidian, ivory, ruby, sapphire, emerald, gold and wood, or your own colours.

Frequently asked questions

How does advantage change a d20 roll?

You roll two d20s and keep the higher. The average goes from 10.5 to 13.8, the chance of a natural 20 from 5% to 9.75%, and the chance of 15 or more from 30% to 51%. Disadvantage keeps the lower die: the average drops to 7.2 and 15 or more comes up only 9% of the time.

What is 4d6 drop the lowest?

The classic way to roll ability scores: roll four d6, ignore the lowest and add the other three. It averages 12.24, a little above the 10.5 of plain 3d6, and gives an 18 about 1.6% of the time. Press “Roll ability scores” to roll all six at once.

Can my party see my rolls?

Yes. Under “Roll together”, type your name and open a table, then share the invite link or the five-letter code. Each roll, by anyone at the table, plays out on every screen and goes into everyone’s history with the roller’s name. No accounts; the browsers connect to each other.
