  description

  A 3D dice roller for tabletop RPGs — D&D, Pathfinder, and any system that uses polyhedral dice.
  
  FEATURES
  • Seven polyhedral dice: d4, d6, d8, d10, d12, d20, d100
  • Click any die button to roll one, or type standard notation (1d20+5, 2d6+3, 4d8-2)
  • Real-time 3D physics — the dice tumble and settle naturally; the result is read from the face that lands up
  • Persistent roll history (last 50 rolls) saved across browser sessions
  • Two visual themes: classic Default and procedural Marble (Chessex-style swirling veining)
  • Five tabletop mat colors — green, black, purple, red, orange
  • Adjustable die size from 12 to 24
  • Light or dark toolbar icon — match your browser theme
  
  PRIVACY
  This extension does not collect, transmit, or share any data. Settings and roll history are saved locally on your device via chrome.storage.local. No analytics. No telemetry. No external network requests at runtime.
  
  PERMISSIONS
  • storage — to save your roll history and preferences locally on your computer.
  
  CREDITS
  3D rendering and physics use @3d-dice/dice-box (Babylon.js + Ammo.js WebAssembly).

  A 3D dice roller for tabletop RPGs — D&D 5e, Pathfinder 2e, and any system that uses polyhedral dice. The dice tumble through a real physics simulation and the value is whatever face actually lands up.
  
  WHAT'S NEW IN 0.3
  • Named rolls / macros — save a roll under a name ("Phase Bolt" = 1d20+7) and click it like a die button. A macro can have several steps that run in order (attack, then damage). Group related macros and they collapse behind one dropdown.
  • A full-tab macro editor — create, edit, delete, organise. Every step is validated when you save, so a saved macro can never break when you click it.
  • Cross-device sync — your settings and macros follow you across every Chrome you're signed into.
  • Copy result — one button puts the last roll on your clipboard as text, ready to paste into a Discord or VTT chat.
  • Keyboard shortcut — Alt+Shift+D opens the roller (rebindable in Chrome's shortcut settings).
  • d100 reads as its two dice — a 23 shows as 20 + 3 in the breakdown, so you can see how the percentile result is formed.
  
  NOTATION (Roll20-compatible)
  • Basic: 1d20, 2d6+3, 1d20-2
  • Compound: 1d20+1d4+5, 2d6+3-1d4
  • Advantage / disadvantage: 2d20kh1, 2d20kl1
  • Drop lowest (ability scores): 4d6dl1
  • Reroll: 1d8r1 (recursive), 1d8ro1 (once), 1d8r<=2, 1d8r>=7
  • Exploding: 1d6!, 1d6!!, 1d6!>=5, 1d20!=20
  • Checks: 1d20+9 vs DC22 (also "vs 22" and "1d20+9>=22")
  
  The seven supported dice are d4, d6, d8, d10, d12, d20, and d100, with up to 100 dice per group.
  
  CHECKS & DEGREES OF SUCCESS
  Add "vs DC<n>" to any roll for a success/failure tag next to the total. Two modes in settings:
  • D&D — nat 20 / nat 1 cinematic crits, otherwise a straight pass/fail.
  • Pathfinder 2e Remastered — the four-degree ±10 scale with the nat-20 / nat-1 one-step shift.
  
  ALSO INCLUDED
  • Persistent roll history; export the whole thing to CSV or JSON. Configurable cap (50 default, up to 1000 for a campaign log).
  • Reroll the last roll by typing just "r", or click a ↻ on any history entry — and a ↻ on a macro run re-runs the whole macro.
  • In-extension help page explaining every notation form for players, not parsers.
  • Two visual themes (classic Default, procedural Marble), five tabletop mat colors, adjustable die size, light/dark toolbar icon.
  
  FAIRNESS
  The face value comes from the physical simulation: whatever side lands up after the dice settle. The underlying randomness uses crypto.getRandomValues end-to-end (Web Crypto API) for every roll decision — no Math.random, no PRNG seeding tricks, just fresh kernel entropy each throw.
  
  PRIVACY
  This extension has no servers, no analytics, no telemetry, and makes no network requests at runtime. Roll history is stored locally on your device. Settings and macros use Chrome's own sync storage, so they follow your Chrome profile across devices — that data is tied to your Google account and managed by Chrome, not by us; we never see it. The CSV / JSON exports are file downloads to your own computer.
  
  PERMISSIONS
  • storage — to save your roll history, preferences, and macros. (This single permission covers both local storage and Chrome's built-in cross-device sync.)
