Dice Roller
Roll any number of dice with any number of sides, see each roll and totals instantly, and use it for tabletop games, classrooms, or random picks quickly.
How to use this tool
- Enter a dice expression such as 3d8+2 and set repeat count.
- Optionally enable deterministic mode with a seed for reproducible runs.
- Review per-roll totals and export CSV or JSON logs for records.
Expression support
- Supported formats include NdM, dM, NdM+X, and NdM-X.
- Dice count and side values are bounded for stability and performance.
- Batch repeats help simulate distributions and expected outcomes.
Practical use
- Track campaign rolls with history rows and exported reports.
- Run repeat batches when evaluating probability behavior.
- Use seeded mode for demo scenarios that must replay identically.
FAQ
- Is randomness cryptographically secure?
- No. This generator is intended for game simulation, not security-sensitive use.
- Can I export every roll in a batch?
- Yes. CSV export includes row-level roll values and totals for each batch run.
- How does deterministic seed mode work?
- The same seed, expression, and repeat count reproduce the same roll sequence.
