How it works
- Choose the number of dice (1 to 10) and the die: d4, d6, d8, d10, d12, d20 or d100.
- Press Roll. Every die is rolled independently with your browser's cryptographic random generator.
- Read each die and the total; Recent results keeps your last rolls, like “3d6: 4 + 2 + 6 = 12”.

Questions
- Are the dice fair?
- Yes. Each die gives every face exactly the same probability, using unbiased sampling on the Web Crypto API.
- Can I roll a d20 or a d100?
- Yes. Choose the sides in the menu: 4, 6, 8, 10, 12, 20 or 100.
- Why do the numbers flicker before stopping?
- That is only an animation. The final values are drawn before it starts and are never changed by it.
