## How do you calculate d100?

**A d100 goes 1–100**, a d10 goes 0-9. Neither allows you to roll a 0, because of the way you count a percentile dice. (00 on the percentile and a 6 on the other dice forms 6, 00 on one and 0 on the other is 100, no option will result in 0.)

## How do you read d10 die?

The die is a d10, and when such a die is rolled, the 0 is **usually read as a 10**. Some RPGs use it as a 0-9, but that’s more of the exception rather than the rule. The only time a 0 on a d10 is read as a 0 is when it’s rolled as a pair of d10s to get a d100, or percentile dice, where a “00” is 100.

## How do D10 dice work?

Much like the D12, the D10 is **primarily used to determine damage from specific weapons or spells**. Additionally, your two D10s can be used when your Dungeon Master determines that something has a percentage chance of succeeding. Usually in a set, the two D10s will be different colors.

## How do you read percentiles?

If a child’s weight is at the **50th** percentile line, that means that out of 100 normal children her age, 50 will be bigger than she is and 50 smaller. Similarly, if she is in the 75th percentile, that means that she is bigger than 75 children and smaller than only 25, compared with 100 children her age.

## What is 00 on a D10?

The one with two digits is just telling you the tens digit, and the one with one digit is the ones digit. If you’re rolling only that die with 0, 10, 20, etc., then a 10 = a 1 and the 00 = a 10. 0 or 00 on a d10 just means **the highest number**.

## How do dice in DND work?

You generate a number between 1 and 100 by **rolling two different ten-sided dice numbered** from 0 to 9. One die (designated before you roll) gives the tens digit, and the other gives the ones digit. If you roll a 7 and a 1, for example, the number rolled is 71.

## How do you read dice rolls?

The first die represents the tens digit, and the second die the ones digit. For example, a roll of 1 followed by a roll of 5 will give a total of 15, while a roll of 3 followed by a roll of 6 will give a total of 36. The average result of the D66 is 38.5, and the standard deviation about 17.16.

## What does 00 mean on a d100?

Also, the “00” is read as a “0” in every other roll of the d100. But specifically for “00” and “0”, **it results in a “100”**. This means that the possible results of a “00” roll with any roll of the d10 is 1, 2, 3, 4, 5, 6, 7, 8, 9, and 100.

## How many dice should I have for D&D?

To start playing, you only need one of each: the D4, D6, D8, D10, D12, and D20, but standard **7-dice sets** also include a second D10 which is used for percentile rolls.

## How do you play dice?

Each player **rolls two dice** and writes the highest value number that you can make with the two numbers on the dice. For instance, if a player rolls a 6 and a 1, they would write “61”. The next player rolls the dice and tries to beat that number. The player with the highest number on a round, scores a point.
