Dice Roller

How to use the dice roller

Use standard dice notation: NdM (e.g. 3d6 = roll three six-sided dice) with optional +X / −X modifier.

Formula & explanation

Each die uses uniform random 1..M from crypto. Total adds them up plus any modifier.

Examples

3d6 → e.g. 4 + 2 + 5 = 11. 1d20+3 → e.g. 14 + 3 = 17. 2d10 → e.g. 7 + 9 = 16.

Frequently asked questions

What does '3d6' mean?

It means roll 3 six-sided dice and sum the results. The format is NdM where N is the number of dice and M is the number of sides on each die.

How do I add a modifier to my roll?

Append +X or -X to your notation, e.g. '1d20+5' rolls one 20-sided die and adds 5 to the result. This is standard in tabletop RPGs like D&D.

What dice types are supported?

Any die with 2 to 1000 sides is supported (e.g. d4, d6, d8, d10, d12, d20, d100). You can roll up to 1000 dice at once.

Can I use this for Dungeons & Dragons?

Yes. Common D&D rolls like 1d20 (attack), 2d6 (damage), 4d6 (ability score generation), and 1d100 (percentile) are all supported.
