Dice Roller (Free) — Multi-Dice & D20

Set sides → count → optional modifier → Roll. See a large total, per-die chips when you roll several, and a copy-ready line for chat or notes. No upload, no signup, no watermark.

Dice roller controls and results

Board night, classroom demo, or quick D&D check — tune sides (D6, D20, D100…), how many dice, and an optional +/− modifier on the sum.

1 Sides & count · 2 Optional modifier · 3 Roll dice · 4 Copy result

Roll result

Recommended: 6 sides × 1 die for a cube; 20 × 1 for a D20; 6 × 2 for backgammon opening. Modifier adds to the sum of all dice (e.g. +5 proficiency). Each click is a new independent roll.

Runs in this tab only—no server upload, no signup, no watermark.

Press Roll dice — the big number is your face (single die) or total after modifier (multi-dice). Chips show each die. Nothing is uploaded.

What this is for

Dice Roller (Free) — Multi-Dice & D20 builds values you can copy: free and instant, works in your browser, no account needed. Passwords, UUIDs, QR codes, barcodes—regenerate when rules or batch size change.

  • New batch when policy or environment shifts
  • Pin the tab during QA and fixture refreshes
  • Local generation
  • Staging seeds, mocks, and load-test data

Fit: Test inputs and assets without installing another app.

Bookmark this tab — game nights always need one more roll. Faster than digging through app stores.

When you need a fair number now

You are teaching probability, playing a board game without a box of dice, or running a quick tabletop check. This page keeps the loop obvious: set up → roll → read the big total → copy if you are posting results in Discord or a worksheet.

How it works

  1. Enter Sides per die (e.g. 6, 20, 100) and How many dice (1–50).
  2. Optionally set Modifier — it adds to the sum of all dice (not each die).
  3. Click Roll dice — each die is floor(Math.random() * sides) + 1 in your tab.
  4. Use Copy roll for a single line you can paste into chat or notes.

Privacy: Dice rolls run locally in your browser. We do not receive your sides, count, modifier, or results.

FAQ

  • Does modifier apply to each die? No — only to the sum of all dice.
  • Is anything uploaded? No — all math stays in your tab.
  • Fair for tournaments? Casual and classroom use only — not certified for regulated play.
  • Mobile? Yes — fields stack; the green panel stays readable when you scroll.
  • Need crypto-grade random? Use tools built for secrets — this uses Math.random.
