Roll dice for a tabletop game

Roll standard and unusual dice — 2d6+3, d20 checks, d100 percentiles — on screen.

The job

Physical dice are missing, or the game calls for more dice or odder dice than you own — a d100, or a fistful of d6. The roller reads the three numbers every game uses: sides per die, how many dice, and the flat modifier.

How to do it

Pick the sides (d4 through d100), the count (up to 20), and type the modifier — positive, negative, or zero. Roll. The output shows every die face, their sum, and the total after the modifier, so nobody has to add under pressure.

Worked example

Your table notation is “2d6+3”. Set sides to d6, count to 2, modifier to 3. A roll of “4 + 2” shows a dice total of 6 and a final total of 9 — the number to compare against the check.

Limits

Rolls use the browser's cryptographic random source and are uniform — a streak of ones is luck, not a defect. There is no physics animation, and the cap is 20 dice with a modifier between −99 and +99.
