Roll a chosen number of virtual dice and inspect both individual faces and the total. The output is useful for trying game rules or observing a distribution across repeated classroom experiments.

How to use this tool
Choose at least two sides and between one and one hundred dice. Two six-sided dice and one twelve-sided die share a maximum but have different possible totals and very different probabilities.
Results and examples
If two six-sided dice show 3 and 5, their total is 8. Another roll samples again; a repeated result is possible and does not by itself indicate that the generator has stopped working.
Limitations
- Math.random is not a cryptographic random generator or an auditable drawing system.
- A short run is not guaranteed to contain every face equally often.

Frequently asked questions
How is a total calculated?
If two six-sided dice show 3 and 5, their total is 8. Another roll samples again; a repeated result is possible and does not by itself indicate that the generator has stopped working.
Can this run an official drawing?
Math.random is not a cryptographic random generator or an auditable drawing system. A short run is not guaranteed to contain every face equally often.
