How is this different from a basic dice roller?

A basic dice roller rolls one die type at a time. This tool lets you combine multiple die types — for example 2d6 + 1d8 + 1d4 + modifier — and roll them all at once, showing individual results and a grand total.

How many dice can I add to the set?

You can add up to 20 of each die type, and up to 7 different die types, giving you up to 140 dice in a single roll.

Are the rolls truly random?

Yes. Each die result is generated with Math.random(), which uses the browser's built-in pseudo-random number generator — the same quality used by browser-based games.

What modifier values are allowed?

The modifier can be any integer from -99 to +99. Enter a negative number to subtract from the total.

Does this save my dice set between sessions?

No. The current dice set and roll history reset when you reload or leave the page.

Summary

This dice set roller lets you build any combination of polyhedral dice — d4, d6, d8, d10, d12, d20, and d100 — into a single roll. Add dice one type at a time, apply a positive or negative modifier, then roll the entire set at once. Each die shows its individual result alongside the running total. A roll history tracks your last ten sets so you can compare results across multiple rolls.

How it works

Click any die button (d4, d6, d8, d10, d12, d20, d100) to add one die of that type to your set.
Use the number input next to each die type to quickly set an exact count.
Enter a positive or negative modifier in the Modifier field (e.g. +3 or -2).
Click Roll to generate a random result for every die in your set.
View individual die results and the grand total, then check the history for past rolls.
Click Reset to clear the dice set and start fresh.
