Is this truly random?

Yes. All randomness uses crypto.getRandomValues() from the WebCrypto API, which provides cryptographically secure random numbers — the same quality used in security-sensitive applications.

What dice types are supported?

d4 (4-sided), d6 (6-sided, standard), d8, d10, d12, d20 (twenty-sided), and d100 (percentile). You can roll up to 100 dice at once.

How does the card deck work?

A standard 52-card deck is shuffled cryptographically. Draw as many cards as you like — drawn cards are removed from the deck until you reset.

Can I roll multiple different dice?

Yes. Use the 'Custom Roll' notation like 2d6+1d8 for a mixed roll.
