Dice Roller

Dice roller for d4, d6, d8, d10, d12, d20 and d100: roll up to 20 dice with a modifier and see each die, the total and your earlier rolls.

Your dice

A modifier, e.g. +2 for 2d6+2. Use a minus for a penalty.

Result

This dice roller throws up to 20 dice of any common size, d4 to d100, and adds them up for you. Two six-sided dice, the default, give totals from 2 to 12, averaging 7. Add a modifier and you get tabletop notation like 2d6+2. It’s free, quick on a phone, and keeps your last ten rolls on screen.

Dice roller: the settings

  • Number of dice: 1 to 20.
  • Sides: d4, d6, d8, d10, d12, d20 or d100. Six-sided dice show pips, the rest show the number.
  • Add to the total: a bonus or penalty, so 1d20+5 or 3d6−1.

Under the result you’ll see the possible range and the average. 3d6 runs from 3 to 18 and averages 10.5, the same average as a single d20, but the totals bunch up in the middle instead of spreading evenly. That’s why 3d6 feels steady and a d20 feels swingy.

What the totals mean

With two dice, 7 is the most common total: 6 of the 36 combinations make it, a 1 in 6 chance. 2 and 12 are the rarest at 1 in 36 each. Craps is built entirely on that shape, and the craps odds calculator shows how the payouts follow it.

For the chance of any total or result with any number of dice, use the dice probability calculator. It works out the exact odds instead of rolling.

Fair dice, every time

Each die is a separate draw from your browser’s secure random generator, with no rounding bias, so a 6 is exactly as likely as a 1. Physical dice aren’t always that good: cheap dice with drilled pips are slightly lighter on the six side. If you’re settling an argument or playing a game over video call, this is the fairer option. For other ways to pick at random, try the coin flip or the random number generator.
