Dice OutcomesDice Outcomes is a small set of dice tools for tabletop games, classrooms and anyone who needs a fair roll. It aims to work the moment the page opens, and to remember your setup when you come back.
The tools
- Dice Roller — any mix of d4 to d100 with a modifier, presets and history.
- D20 Roller — normal, advantage and disadvantage rolls.
- Dice Probability — exact odds and distributions.
- Custom Dice Tables — your own outcome tables, rolled with the same engine.
How it works
All tools share one dice engine. Rolls use the browser's cryptographic random number generator with rejection sampling, so every face is equally likely. Probabilities are counted exactly rather than estimated. Everything runs in your browser — there's no account, and your data stays on your device (see Privacy & data).
