Dice notation for tabletop play

How NdS±M dice notation works in this online roller—examples for d20, 2d6, and 2d6+3 that match the live tool.

Tabletop groups often write rolls as NdS with an optional modifier. This guide covers only the notation this site actually parses and rolls.

Open the roller, type an expression in Advanced notation, or use the count/sides/modifier controls—the result is the same engine either way.
