Questions
How do I roll with advantage?
Choose Advantage in the Roll box. Two d20s are rolled and the higher one is kept.
Can I roll a d100?
Yes. Choose d100 in the Sides box.
How do I roll damage like 2d6+3?
Choose 2 dice, d6 and a modifier of 3.
Are the dice fair?
Yes. Each side has the same chance on every roll, and the result is chosen before the dice tumble, using your browser's secure random generator.
Do the dice remember earlier rolls?
No. Every roll is independent, so a streak of the same number does not make it less likely next time.
Is it really random?
Yes. It uses your browser's secure random number generator, the same kind used for security. Each outcome is equally likely, and earlier results do not affect the next one.
Is anything saved or sent?
No. Names and results stay in your browser and are gone when you close the page.
Is it free?
Yes. No sign-up, no limit.
