How are the dice results calculated?

Each die is rolled using JavaScript's Math.random() to generate a random integer from 1 to the number of sides. The modifier is then added to the sum of all individual rolls.

What dice types are supported?

The roller supports all standard tabletop polyhedral dice: d4, d6, d8, d10, d12, d20, and d100 (percentile).

Can I roll more than one die at once?

Yes. Set the count input to any value from 1 to 100. All dice are rolled simultaneously and individual results are shown alongside the total.

How do I use the modifier?

Enter a positive number (e.g., 5) to add to your total, or a negative number (e.g., -2) to subtract. This is useful for ability modifiers and bonuses in D&D.

What does 2d6+3 mean?

It is dice notation: the first number is how many dice, the number after "d" is the sides on each die and the last number is added to the total. 2d6+3 means roll two six-sided dice and add 3, so the result runs from 5 to 15. Set Number of Dice to 2, pick d6 and enter 3 as the modifier.

Can I roll different dice together, like 1d20 and 2d6?

Not in a single roll. Each roll uses one die type, so roll the d20 first, then switch to d6 and roll two. Both results stay in the roll history so you can add them up.

Quick answer

Pick a die, set how many to roll and add a modifier. The roller shows each die and the total. Every face is equally likely, so one die averages (sides + 1) ÷ 2 and a roll of several dice averages that times the number of dice.

Examples

Roll	Range	Average
1d6	1–6	3.5
2d6	2–12	7
1d20	1–20	10.5
4d6	4–24	14
2d6 + 3	5–15	10
1d100	1–100	50.5
