Which dice can I roll?

The selector includes standard tabletop dice with different side counts. Every die in one roll uses the selected type.

Is the modifier added to every die?

No. Individual face values are summed first, and the modifier is applied once to that combined dice sum.

Are results based on an animation or secure randomness?

They come from cryptographically secure browser random values with rejection sampling. The displayed faces report those results directly.

Can I mix different die types in the same roll?

Not in one operation. Roll each die type separately and combine the totals if a game requires a mixed dice pool.

Frequently asked questions

About Dice Roller

Dice notation is compact, but a useful digital roller should still expose the arithmetic. This workspace lists every die result, separates their raw sum from the chosen modifier and then presents the final total. Large pools can be rolled without manually adding up to 100 faces.

Each allowed side has an even chance because out-of-range random samples are discarded rather than compressed unevenly. The roller is suited to tabletop checks, classroom probability exercises and quick decisions, but it does not store campaigns or automate game-specific rules.
