How to roll dice online
- Pick your dice. Click a die (d4, d6, d8, d10, d12, d20 or d100) or its + to add one, and − to take one away. Hold + or − to change the count quickly, and use Clear all to start from an empty table. You can put up to 30 dice on the table and mix any types.
- Roll. Press Roll, the Space bar, or click the table. The dice fly in, bounce off each other and the edges, and settle. Every bounce makes its own sound at the exact moment you see it: harder hits are louder and brighter, small dice click higher, and each sound comes from where the die hit. Click again to skip straight to the result.
- Read the result. The total is shown on the table and below it, together with every die’s value, the sum, and any modifier. Each roll is saved in History.
The quick picks cover the common cases: a single die, 2d6 for Monopoly, Catan and backgammon, a d20, rolls with advantage or disadvantage, 4d6 drop lowest for ability scores, five dice for Yahtzee, a d100 and a full set of RPG dice.
Dice notation
Type what you want to roll in the notation box. It uses the standard tabletop format, NdX: N dice with X sides.
3d6: three six-sided dice, added up.d20is the same as1d20.2d8+3or1d20-1: add or subtract a fixed modifier.1d8+2d6: mix different dice in one roll.4d6kh3: roll four, keep the highest three (the same as4d6dl1, drop the lowest one).2d20kh1is advantage and2d20kl1is disadvantage: roll two d20s and keep the higher or the lower one.d%ord100: a percentile roll with two ten-sided dice, one for the tens (00 to 90) and one for the units (0 to 9). 00 and 0 together read as 100.
Which die is which
- d4 (a pyramid) has no top face: read the number that stands upright at the top point. It is the same on all three visible sides.
- d6 is the classic cube, with pips or numbers (switch under Look & sound). Opposite faces add up to 7, as on real dice.
- d8, d12 and d20 show the result on the face that points up. The 6 and 9 are underlined so you can tell them apart.
- d10 here is numbered 1 to 10. The two percentile dice of a d100 are the only ones that use 00–90 and 0–9.
With the default By die type colors every kind of die has its own color, which makes a mixed handful easy to read. You can also pick one color for all dice, choose a wood, felt or stone table, and set the volume.
Are the rolls fair?
Yes. Each die’s result is drawn with your browser’s cryptographic random number generator (the Web Crypto API), so every face of every die has exactly the same chance, and no roll depends on the one before. The 3D physics then throws the dice for real, and each die is numbered so that the drawn value lands face up. That way the animation can never bias the outcome, even though a simulated table, like a real one, is never perfectly even.
Nothing leaves your device: the dice, the physics and the sounds all run in your browser, and your settings and history are stored only in this browser.
Odds and probabilities
The Odds tab shows the exact chance of every total for the dice you picked, the average and the most likely result, and how likely your last roll was. Two dice make a bell shape: with 2d6 a 7 comes up one time in six (16.7%), while 2 and 12 each come up only one time in 36 (2.8%). Advantage raises the average d20 roll from 10.5 to about 13.8, and 4d6 drop lowest averages about 12.2 instead of 10.5 for 3d6.

Troubleshooting
- No sound: check that Sound on is showing and your device isn’t muted. On iPhone and iPad, the silent switch mutes web pages too. Browsers only play sound after you click or press a key on the page.
- No 3D table: the dice need WebGL. If it is turned off (some privacy settings and old graphics drivers do this), you can still roll: the results appear as numbers.
- Animation feels too much? If your device is set to reduce motion, the dice skip the throw and land straight away.
- Rolling for a group: use Full screen on a TV or projector and roll with the Space bar or the Next button of a presentation clicker.
