❄️ brrrdle

A polished Wordle + Hurdle hybrid — daily puzzles, chained sessions, and an icy brrr aesthetic.

Guess the word. Then guess five more. Stay frosty. 🧊

✨ What is brrrdle?

brrrdle is a mobile-first, accessible, production-minded word game that blends two beloved formats:

• og mode — classic single-puzzle, Wordle-style play.
• go mode — chained five-puzzle, Hurdle-style play where solved answers pre-fill carry-over rows into the next puzzle.

It ships with guest progress, optional cloud accounts, post-game definitions, emoji sharing, an in-app economy, and Progressive Web App foundations — all wrapped in a dark-first UI with icy brrr accents.

Project status: v1 launch scope plus approved addenda through Phase 18 (answer-difficulty tiers, Word Explorer / Go / Settings polish, and the daily-overlap fix) are implemented; Phase 19 (enhanced statistics visualizations, a configurable Go puzzle count, full resume-most-recent-game activation, advanced polish, and a light theming foundation) is planned and awaiting approval. Production deployment requires explicit release approval after PR review — do not trigger a production deploy without it.

🎮 Features

Core gameplay

• 🟩 Exact Wordle tile coloring, including correct duplicate-letter accounting, from a single canonical source of truth.
• 🔗 go chained sessions of five puzzles with carry-over pre-fills between rounds.
• 🧠 Hard Mode for og and go, in both daily and practice contexts.
• 📅 Daily puzzles fixed at 5 letters; Practice supports word lengths 2 through 35.
• ⌨️ Physical keyboard + on-screen keyboard input with clear loading, empty, error, and invalid-guess states.

Progression, economy & stats

• ⭐ XP, levels, and coins earned through play.
• 🛒 Consumables — Reveal One Letter and Remove Incorrect Letters.
• 💸 Pay-to-Continue in daily and practice, scaled by word length and completion.
• 📊 Per-mode statistics (og vs go) tracked from day one.

Words, definitions & discovery

• 📚 Local curated word lists for every length 2–35 (hundreds of thousands of real English words).
• 🎚️ Answer-difficulty tiers (Casual / Standard / Expert) that subset the answer pool only — valid guesses stay identical across tiers.
• 🔍 Post-game definitions with a graceful lookup chain: bundled data → Dictionary API → Wiktionary → an always-available Search Google button.
• 🧭 Word Explorer tab for browsing and inspecting the dictionary.

Accounts, sharing & platform

• 👤 Guest play with full local progress, coins, levels, stats, settings, and history.
• ☁️ Optional Supabase accounts with email verification, cloud sync, and a guest-to-account transfer prompt.
• 🟦🟨⬜ Classic emoji sharing generated from canonical tile states.
• 🏁 Ranked Practice Multiplayer with a transparent Elo model documented in docs/ranked-multiplayer.md.
• 📱 PWA shell with offline caching where reasonable.
• 🔊 Toggleable sound effects and a Feedback tab.
• 🛡️ Protected admin route (/api/admin-refresh) for word-list refresh, gated by Supabase auth + an admin role.

🧊 Why brrrdle?

• Faithful, not fragile. Tile coloring, Hard Mode, and sharing all consume one canonical engine — never re-implemented per surface.
• Accessible by default. Targets WCAG AA: semantic controls, visible focus, keyboard-only navigation, reduced-motion support, and readable contrast.
• Offline-friendly data. Word lists are bundled locally, so daily play stays fast and resilient.
• Governed & auditable. Every change follows a written constitution, a phased plan, and per-phase progress reports.

🚀 Quick start

# 1. Install dependencies from the lockfile (reproducible)
npm ci

# 2. Start the dev server
npm run dev

Then open the printed local URL (Vite defaults to http://localhost:5173).

Use npm install only when you intentionally change dependencies; otherwise prefer npm ci.

Optional: configure Supabase (for accounts/sync)

cp .env.example .env.local
# then fill in your public Supabase project URL + anon key (see "Environment variables" below)

Guest mode is fully playable without any Supabase configuration.

📜 Available scripts

Script	Description
npm run dev	Start the Vite dev server with HMR.
npm run build	Type-check (tsc -b) and produce the production bundle in dist/.
npm run preview	Serve the built dist/ locally to smoke-check production output.
npm run test	Run the Vitest unit-test suite once.
npm run lint	Lint the project with ESLint.

Recommended verification before a PR

npm run lint
npm run test
npm run build
npx tsc -p tsconfig.api.json --noEmit   # type-check the serverless API project

🔐 Environment variables

Copy .env.example to .env.local and provide public Supabase values only:

VITE_SUPABASE_URL=https://your-project-ref.supabase.co
VITE_SUPABASE_ANON_KEY=your-public-anon-key
SUPABASE_URL=https://your-project-ref.supabase.co
SUPABASE_ANON_KEY=your-public-anon-key

• VITE_* values are public and shipped in the browser bundle — use only the public project URL and anon key.
• SUPABASE_URL / SUPABASE_ANON_KEY are server-side aliases used by /api/admin-refresh; they should point to the same public URL and anon key.
• Never commit secrets, service-role keys, JWT signing secrets, database passwords, or any privileged credentials.

---

🧩 Supabase & admin setup

See docs/supabase.md for schema, Row-Level Security, account sync, and admin-role guidance. The browser client uses only the public project URL and anon key; admin roles must be assigned through a secure Supabase dashboard or server-side process — never from browser code.

The protected refresh endpoint is POST /api/admin-refresh. It requires a Supabase bearer token for a user whose app_metadata.role is admin (or whose app_metadata.roles contains admin):

Caller	Response
Unauthenticated	401
Authenticated, non-admin	403
Authenticated admin	Refresh acknowledgement

---

🚢 Deployment targets

• Game: Vercel, using npm run build and the dist/ output configured in vercel.json.
• Blog / docs: GitHub Pages + Jekyll from docs/.

See docs/deployment.md for deployment and verification checklists (environment-variable warnings, PWA asset checks, and production smoke checks).

---

📱 Progressive Web App

brrrdle registers a service worker and ships a web manifest so it can be installed and remain usable offline where reasonable. Word-list handling is optimized so daily mode loads quickly and gameplay stays smooth.

🧭 Governance & authoritative sources

brrrdle is built under a strict, written governance model. When in doubt, these documents win — in this order:

1. CONSTITUTION.md — binding rules for scope, review gates, verification, security, and conduct.
2. BRRRDLE-SPEC.md — the product specification.
3. BRRRDLE-OVERVIEW.md — the approved project plan.
4. AGENT-IMPLEMENTATION-PLAN.md — root shim for the active lightweight plan and the archived full historical plan.
5. CHANGELOG.md — root shim for historical and Phase 24 changelog locations.
6. planning/ — current planning hub, specs, history, and testing strategy.
7. progress/ — per-phase progress reports and PROGRESS.csv.

The agent workflow is model-agnostic — any sufficiently capable coding model (e.g., Claude Opus 4.8) can drive it.

---

🤝 Contributing

This project follows a phase-gated, verification-first workflow:

1. Read the governance docs first — CONSTITUTION.md, then BRRRDLE-SPEC.md, then AGENT-IMPLEMENTATION-PLAN.md and the relevant planning files it links to.
2. Make small, cohesive, reviewable changes tied to the current phase. Avoid speculative refactors and out-of-scope features.
3. Preserve canonical logic — never duplicate tile-coloring or Hard Mode rules; consume the shared engine.
4. Verify before you finish — run npm run lint, npm run test, npm run build, and npx tsc -p tsconfig.api.json --noEmit.
5. Never weaken or remove tests to make a phase pass, and never commit secrets.
6. Update the changelog and progress artifacts when a phase requires it, then halt for review at the relevant gate.

♿ Accessibility & 🔒 security at a glance

• Accessibility: WCAG AA targets — semantic controls, visible focus, keyboard-only navigation, dialog accessibility, status announcements, readable contrast, and reduced-motion support.
• Security: no committed secrets; no service-role privileges in browser code; Row-Level Security for user data; server-side admin authorization; imported word/definition data treated as untrusted; safe external-link behavior for new tabs.

Built with ❄️ and care. Stay frosty.
