What dice types are supported?

d4, d6, d8, d10, d12, d20, and d100 (percentile). You can mix any combination in one expression.

How does advantage/disadvantage work?

When enabled, the tool rolls the first die type in your expression twice and keeps the higher (advantage) or lower (disadvantage) result before adding modifiers.

Is the randomness truly random?

Yes. Dice rolls use the Web Cryptography API (crypto.getRandomValues) which provides cryptographically strong random numbers.

How many rolls are stored in history?

The last 10 rolls are shown. Older entries are automatically removed when you roll again.
