Roll a d10 online

One ten-sided die is ready to roll. Tap it, press Roll or hit the Space bar, and you get a number from 1 to 10, each with a 10% chance. The average roll is 5.5.

The odd shape of a d10

Ten faces cannot be arranged as a regular solid, so the d10 is a pentagonal trapezohedron: ten kite-shaped faces, five meeting at the top point and five at the bottom. Most real d10s are numbered 0 to 9, and the 0 is read as 10. The on-screen die shows 1 to 10 directly, so there is nothing to convert.

Games that roll d10s

Fifth edition fantasy. Fighters, paladins and rangers use a d10 as their hit die, and the heavy crossbow deals 1d10 damage.
Dice pool games. Several horror and science-fiction role-playing games have you roll a handful of d10s and count the dice that reach a target number. Tap “one die” to roll up to 10 at once, then count the hits.
Percentile rolls. Two d10s make a d100: one for the tens, one for the units. See the d100 roller to roll a percentage directly.
Ratings and choices. A score out of ten, one of ten options, a random digit if you read 10 as 0.

Counting successes

If your game asks for dice that show 8 or more, each d10 has a 30% chance of being a success. Roll five and you get one and a half successes on average; roll ten and you average three. Because each die is independent, rolling more dice raises the average, but a roll with no successes at all is still possible: with five dice, it happens about 17% of the time.

Questions

Why does a real d10 have a 0 on it?

Most d10s are numbered 0 to 9 so that two of them can be read as a percentage. When you roll a single d10, the 0 counts as 10.

What is the average roll of a d10?

5.5, the midpoint of 1 and 10.

How do I roll several d10s and count successes?

Tap “one die”, choose how many dice, keep 10 sides and press Roll. Count the dice that reach your target number; the total above them is the sum, which pools usually ignore.

Is this dice roller free?

Yes. It is free to use, funded by advertising, with no account and no app to install.
