Frequently asked questions
Are the rolls fair?
Each die uses your browser's cryptographically secure random source with rejection sampling, so every face has exactly the same probability.
Does it support custom dice like d30?
Yes. Use the custom dN field — any number of sides from 2 up to 1000.
Can I add modifiers like +5 or -2?
Yes. The modifier is added to the total of all dice rolled in that round.
Is anything sent to a server?
No. Rolls happen entirely in your browser.
