Why dice notation like '2d6+3' is worth knowing

Tabletop gaming's standard dice notation, [number of dice]d[number of sides]+[modifier], is a compact way to describe exactly what to roll and add: "2d6+3" means roll two six-sided dice and add 3 to the total. Learning this notation once means you can read any tabletop game's rulebook or damage chart directly and roll it here without translating it into plain English first. Most tabletop RPGs, including D&D, use this exact notation throughout their rules.

Frequently asked questions

What dice types are supported?

Standard tabletop sets: d4, d6, d8, d10, d12, d20, and d100, individually or combined in a single roll.

Can I roll multiple dice at once and get an automatic total?

Yes. Enter a combination like 3d6, and it rolls all three and totals them automatically rather than requiring you to add each result yourself.

Are the rolls genuinely random, or predictable?

Rolls use your browser's cryptographic random number generator (crypto.getRandomValues), which produces genuinely unpredictable results, more than sufficient for tabletop gaming and any casual use.
