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.
