Every roll uses your browser’s secure random generator, so each face has an equal chance, just like a fair die.

D20 dice roller and D&D dice notation

Tabletop games write dice rolls as NdS+M: N dice with S sides, plus a modifier M. This dice roller understands that notation:

d20 or 1d20: one twenty-sided die, used for attack rolls, ability checks and saving throws.
1d20+5: a D20 roll plus a +5 bonus.
2d6+3: two six-sided dice added together, plus 3, a typical weapon damage roll.
4d6: four six-sided dice, often used for rolling character ability scores.
d100 or d%: a percentile roll from 1 to 100.

For a roll with advantage or disadvantage, roll 2d20 and use the higher or lower die, which the tool shows separately.

Dice odds: which totals come up most?

With one fair die, each face has a 1 in 6 chance. With two dice, totals in the middle are far more common than the ends, because more combinations add up to them:

7 is the most likely total, with 6 of the 36 combinations (about 16.7%).
6 and 8 each come up 5 times in 36 (about 13.9%).
2 and 12 are the rarest, only 1 time in 36 (about 2.8%) each.

That is why 6 and 8 are the best numbers in games like Catan, and why rolling doubles in Monopoly feels lucky: it happens 1 time in 6.

FAQ

Is this online dice roller fair?

Yes. Each roll uses your browser’s cryptographic random number generator, and the tool removes rounding bias, so every face of every die is equally likely. Earlier rolls never affect the next one.

Can I roll more than one type of die at once?

Roll each type separately, for example 1d8 and then 2d6, and add the totals. The roll history keeps both results on screen.

Does Google have a dice roller?

Yes. Searching “roll a die” on Google shows a simple roller, one of its many built-in tricks like do a barrel roll. This tool adds up to 50 dice, modifiers, D&D notation and a roll history.
