What this calculator is for

This calculator is for tabletop games, classroom probability demos, and quick random-number needs when physical dice are not available.

Tips

Use the modifier field for rule-based bonuses or penalties instead of adding them mentally after the roll.
If you are testing probabilities, repeat the same setup several times rather than judging fairness from a single roll.
