You are wrong about at least one of these

You probably think	Actually
🃏 You can stack a +2 on a +2 in Uno	No. Never could. Mattel said so out loud in 2019 and the internet refused to accept it
🎩 Free Parking pays out the tax pile	No. It has never done anything, in any edition, ever
🃏 You draw until you get a playable card	No. You draw exactly one and move on
🌾 You can trade whenever you like in Catan	No. Only on the active player's turn, and only with them
🎩 Landing exactly on Go pays double	No. It never has

Everybody plays these. Nobody checked.

That gap is the whole project. Rules are easy to find — every box has them. Rulings are not: what to do at 9pm when your uncle is certain, you are certain, and the box is in the loft.

Try it in ten seconds

$ npx @mohitagw15856/rulebook uno "can I stack a draw 2"

Can you stack a Draw Two on a Draw Two, or a Draw Four on a Draw Four?
● NOT AN OFFICIAL RULE   played by almost everyone, almost everywhere

  No. Under the published rules there is no stacking. A player hit with a Draw
  Two draws two cards and loses their turn — they cannot pass the penalty
  along. Mattel stated this publicly in May 2019 and a large part of the
  internet refused to believe it.

  The house version

  The near-universal house version lets you answer a Draw Two with your own
  Draw Two, passing an accumulating penalty around the table until someone
  cannot respond and draws the entire pile.

Nothing to install, nothing to sign up for, no network calls.

🤖  Give it to your AI

Ask any assistant whether you can stack a +2 in Uno and it will usually say yes, confidently, because that is what most of the internet says. This hands it the sourced answer instead.

{ "mcpServers": {
    "rulebook": { "command": "npx", "args": ["-y", "@mohitagw15856/rulebook", "mcp"] }
} }

Four tools, no dependencies, ~200 lines of MCP over stdio: settle_rules_dispute · get_game_facts · plan_game_night · list_contested_rules

The dispute tool is explicitly told not to invent an answer when the registry has nothing — it returns a "file it" link instead. That is the whole point of pointing a model at a registry rather than at its own memory.

🌐  The JSON API

Static files on a CDN. No key, no rate limit, nothing to go down on its own.

$ curl https://mohitagw15856.github.io/rulebook/api/games/uno.json
$ curl https://mohitagw15856.github.io/rulebook/api/hottest.json

/api/index.json	Counts, endpoints, the game list
/api/games.json	Everything, one array
/api/games/{slug}.json	One game, rulings included
/api/rulings.json	All 196 rulings, flat
/api/hottest.json	The 40 most contested

There is also a Slack and Discord bot — one file, no dependencies, signature verification via node:crypto — and an iOS Shortcut recipe that reads the same API.

🖨️  Print it and put it in the box

Three things print straight from a browser. No PDF library, no dependency — just HTML and SVG with @page rules.

The booklet	The entire registry as a printable book. Every game, every ruling, every tiebreak.
The card deck	196 poker-sized ruling cards. Print double-sided — the backs are laid out mirrored so each answer lands behind its own question. Hold one up, everyone guesses official or made up, turn it over.
rulebook card catan	One A4 sheet per game. Fold twice, leave it in the lid.

The per-game card carries setup by player count, the turn, the four rules your table gets wrong, and a QR code to every ruling.

The QR encoder is written from scratch, and it didn't work at first

No dependencies means no QR library, so it's ~250 lines implementing byte mode, error correction level M, Reed–Solomon over GF(256), and mask selection.

The first version produced something that looked exactly like a QR code and was completely unscannable — the format-information bits were in the wrong cells. I found out by decoding it with a real barcode scanner rather than trusting my eyes. rulebook qr <game> prints one straight to your terminal.

---

🎨  What does it even look like?

Every game has an illustration, and every one is drawn rather than collected:

The obvious way to show somebody a game is a photo of the box. Every one of those is copyrighted — and a project that refuses to paste a publisher's words would be drawing a strange line by pasting their photographs.

So they're built from primitives: a fanned hand, a chequered board, a hex field, a rack of tiles. Stylised on purpose, labelled "illustration, not a photograph", and generated by lib/art.mjs so a new game gets one for free.

▶️  Play them online, free

Nineteen games link to somewhere you can actually play, right now, at no cost:

Lichess	Chess. Free, open source, funded by donations, no advertising
PlayOK	Xiangqi, backgammon, cribbage, ludo — no account needed
cardgames.io	Hearts, spades, gin rummy, Go Fish, Yahtzee, crazy eights
Board Game Arena	Jaipur, 7 Wonders Duel, Azul, Hive, Patchwork
codenames.game	Codenames, no account, share one link
Woogles	The crossword game, free and open source

Every link was checked before being added, and the monthly rot job checks them alongside the sources — a dead play link wastes somebody's evening.

No gambling sites. Poker and blackjack have no link here on purpose.

📋  The facts no box prints

rulebook about <game> is where the unglamorous, genuinely useful stuff lives.

Setup and pack-away time	A 20-minute setup quietly ruins a 30-minute game, and no box mentions it
Downtime between your turns	The honest measure of whether a game is bearable to sit through. It is why Monopoly is hated and Codenames is not
The tiebreak	Every game has one — including "it cannot happen" — and almost nobody knows it. All 36 recorded
Handicaps	How to make it fair between an expert and a beginner, or an adult and a seven-year-old
How people cheat	And how to spot it. Recorded so it can be caught, not so it can be done
When to give up	Every game has a fair moment to stop. None of them print it
How it changed	Edition timelines, so you know which rule arrived in 2015

Rulings can also link to rulings they compound with. Play both Uno house rules — stacking and draw-until-playable — and hands reach sizes neither rule alone predicts. Those links are cross-checked at build time.

🏠  Your table's constitution

Every group plays differently. Say so once, in a .rulebookrc, and every ruling answers with your version first and the published rule second:

table: The Thursday Lot
house_rules:
  uno/stacking-draw-cards: yes        # we stack, and we know it isn't real
  monopoly/free-parking-jackpot: no   # we play it properly
  ludo/blocking-two-tokens: yes

Commit it. Send it to anyone joining game night. It settles more arguments before they start than any amount of looking things up afterwards.

💻  The website

mohitagw15856.github.io/rulebook

Same data, same code — the scoring engines and the search are the same modules, imported as plain ESM. No bundler, no second implementation that can quietly disagree with the terminal.

It also does things the terminal can't:

• 🔎 Search every game's rulings at once
• 🌍 See which rules are played differently in different countries
• 📊 A bar chart of how much every box lies about playtime (Monopoly: +120 min)
• 🧾 A round-by-round scorepad that saves to your device
• 📴 Installs as an app and works with no signal

Every ruling has its own link that unfurls with the verdict — paste one into the group chat and let it do the arguing:

https://mohitagw15856.github.io/rulebook/r/uno/stacking-draw-cards/

---

✍️  Add an argument

This is the valuable bit, and it takes two minutes. One entry in one YAML file. No code, no build step, and a form if you'd rather not touch YAML at all.

- id: free-parking-jackpot
  question: Does landing on Free Parking pay you the money in the middle?
  asked_as:
    - free parking money           # ← how people actually type it
    - do you get the tax money on free parking
  kind: house-rule
  official: false
  prevalence: near-universal       # ← how many people play it anyway
  verdict: >
    No, and it never has been — not in any edition of the rules...

asked_as matters most. It's how search finds your ruling when somebody types what they'd genuinely shout across a table.

Run npm run ci before opening a PR — it validates, checks your prose is your own, runs 97 tests, verifies nothing changed shape, and rebuilds this file.

CONTRIBUTING.md has the rest, and MAINTAINERS.md explains adopting a game — about an hour a year, and the single most useful thing anybody can do here. 4 of 36 games are currently verified.

Not sure where to start? node scripts/starter-issues.mjs lists twenty games worth adding, each with an argument it is already known for.

Adding a whole game, or a scorer

One game is one folder: game.yml, rules.md, rulings.yml, teach.md, and optionally score.mjs and odds.mjs. Copy the closest existing game — npm run validate names every missing field, so there's no schema to memorise.

The fields people skip and shouldn't: downtime (how long between your turns — the honest measure of whether a game is bearable, and nobody publishes it), min_age (the age it genuinely works at, not the age on the box), and concession (when it's fair to stop).

---

🔍  How much of this should you believe?

A registry that says "everyone plays it this way" had better be able to show its working. Three mechanisms, all visible:

Verification. Every game records who checked its facts, when, and against what. rulebook verify lists them. Right now 4 of 36 are verified and the other 32 say so plainly — unverified is not the same as wrong, and inventing 36 dates would be exactly the dishonesty this project argues against.

Sources that disagree. A ruling can carry several sources, each recording what it claims and whether it supports the verdict. The Ludo blockade is the first real case: Wikipedia presents it as standard, British sets omit it, and the entry now says so rather than quietly picking a winner.

Votes. prevalence is currently somebody's judgement. rulebook vote lets you report how your table actually plays, and every ruling shows n= beside its claim. With no votes it says "a judgement, not a survey" rather than showing a confident zero. It records where you learned a rule — family, friends, club, online — because rules travel through families far more than through countries, and data/votes.yml ships deliberately empty.

Tests that do not rely on my imagination. The scorers carry property tests over ~1,400 generated deals, checking rules rather than examples: poker comparison is a total order, seven cards never score below the best five inside them, and melding can only ever reduce deadwood.

$ npm run coverage     # what is missing, and how old the facts are
$ rulebook verify      # which games have been checked, and when
$ npm test             # every test, including the property tests

⚖️  About the rules themselves

How a game is played isn't copyrightable. That's the idea/expression split — settled since Baker v. Selden (1879) and stated flatly in 37 CFR 202.1(b), which excludes "the idea for a game" from copyright.

A publisher's wording is. So every word of rules here was written from scratch by someone who understood the game, and npm run check enforces it: no copyright notices, no ® or ™, no long quotations, no sentence appearing in two games.

It has caught me twice. That's the point of having it.

Game names and trademarks belong to their owners. Nothing here is affiliated with or endorsed by any publisher.

Code is MIT. The game data is CC BY 4.0 — take it, build something.

The wall of shame

Every one of these is a house rule. None of them is official. Most people have played them their whole lives without ever knowing that.

Game	"Rule"	The actual rule
Crazy Eights	Do Twos make the next player draw, and do Queens skip?	Not part of the base game.
Monopoly	Do you collect money from Free Parking?	No. Free Parking does nothing at all in the published rules. It is a resting space and pays nothing. This is probably the most widely played rule that…
Pablo	Which cards have powers?	There is no single authority, so no set is official. The most widely used set is below, and it is worth stating out loud before dealing.
Pablo	What happens if you call Pablo and are not lowest?	Universally penalised, but the size varies.
Uno	Can you stack a Draw Two on a Draw Two, or a Draw Four on a Draw Four?	No. Under the published rules there is no stacking. A player hit with a Draw Two draws two cards and loses their turn — they cannot pass the penalty a…
Uno	Do you keep drawing until you get a card you can play?	No. Officially you draw exactly one card. If it can be played you may play it immediately; if not, your turn ends.
