Question 1

Which dice are supported?

Accepted Answer

All the standard RPG dice: d4, d6, d8, d10, d12, d20 and d100. You can combine them in any way, e.g. 1d20+5, 3d6+2 or 4d10.

Question 2

Which dice notation works?

Accepted Answer

Standard pen-&-paper notation: NdM (e.g. 3d6) with an optional modifier (+2, -1) and multiple terms (3d6+1d4+5). Keep-highest (4d6kh3) and keep-lowest (2d20kl1, i.e. disadvantage) are supported too.

Question 3

Does the site store my rolls or data?

Accepted Answer

No. History, saved formulas and settings stay only in your browser (localStorage). Nothing is sent to a server. We don’t use our own tracking cookies; only Google AdSense serves ads — with a consent banner for EU users.

Question 4

Does dice-roll.online work for DSA (Das Schwarze Auge)?

Accepted Answer

Yes. For DSA skill checks you can roll 1d20 three times, or use 3d20 as a single roll. Damage rolls like 1d6+4 or 2d6+2 work the same as in D&D.

Question 5

What do the crit and fumble highlights mean?

Accepted Answer

On a 1d20, a 20 is highlighted as a critical hit (green) and a 1 as a fumble (red). In the settings you can flip which side counts as the crit — useful for systems where lower is better.

Question 6

Is dice-roll.online truly random?

Accepted Answer

Yes. We use crypto.getRandomValues — the browser’s cryptographically secure RNG — instead of the weaker Math.random(). The distribution is noticeably more uniform than most physical dice.

Question 7

Do I need an account?

Accepted Answer

No. dice-roll.online works without sign-up, without email and without an app install — just open the page and roll.
