hidden11

Daily football lineup puzzle built with Next.js, React, TypeScript and Tailwind CSS.

Player data provenance and clue rules are documented in docs/data-sources.md.

Growth features

• Localized home pages: / (en) plus /es, /fr, /de, /it, /pt — server-rendered intro, how-to-play and FAQ (FAQPage JSON-LD) with hreflang alternates on every home.
• Archive, in six languages: /archive and /<locale>/archive list past puzzles; /puzzle/<n> and /<locale>/puzzle/<n> publish answers for past days only (today and future 404). Answer pages carry a sentence of real context per player — club, league, nationality, former clubs and honours — plus Article and BreadcrumbList JSON-LD, and are prerendered (generateStaticParams + hourly ISR) rather than rendered per request. /play/<n> replays a past puzzle without touching stats or streak.
• Challenge loop: shared result links (/r/<code>) offer "Accept the challenge" → /?challenge=<code>. If the challenge matches today's puzzle, the game shows the rival's score and a head-to-head verdict on the result screen.
• Compact share text: one line per difficulty with the final attempt grid — built in lib/share.ts.
• PWA: app/manifest.ts + icons in public/ (regenerate with node scripts/generate-icons.mjs).
• Named challenges: the share sheet takes an optional display name that travels inside the share code, so /r/<code> reads " challenges you" in the page, the OG image and the head-to-head verdict. The name is sanitised on the way out and on the way in.
• Daily reminder: an opt-in Web Push subscription plus a PWA install prompt, offered once the day is finished. The push is sent without a payload (VAPID header only, no content encryption); the notification copy lives in the service worker's Cache Storage (public/sw.js).
• First-party funnel: every game event is mirrored to POST /api/events alongside GA4, so the funnel survives ad blockers. Schema and the funnel/retention/share-channel views are in deploy/sql/hidden11-events.sql.
• Daily teaser: GET /api/teaser returns a spoiler-free localized teaser for today's puzzle (first Easy clue). deploy/n8n-daily-teaser.json is an importable n8n workflow that posts it daily through the Postiz public API (set POSTIZ_API_KEY in n8n and fill in the integration ids inside the Code node).
• IndexNow: node scripts/submit-indexnow.mjs [--today] submits the sitemap URLs to Bing, Yandex and Seznam. The key file lives in public/<key>.txt; the key is in pass show hidden11/indexnow-key. Google has no ping endpoint any more — its sitemap is submitted once from Search Console.

Local development

npm install
npm run dev

Open http://localhost:3000.

Optional analytics env vars:

• NEXT_PUBLIC_GA_MEASUREMENT_ID: GA4 measurement ID, e.g. G-XXXXXXXXXX
• NEXT_PUBLIC_CLARITY_PROJECT_ID: Microsoft Clarity project ID

Optional feedback env vars:

• N8N_FEEDBACK_WEBHOOK_URL: n8n webhook URL used to receive feedback submissions

Optional funnel-analytics env vars:

• N8N_EVENTS_WEBHOOK_URL: n8n webhook backing POST /api/events (workflow: deploy/n8n-events.json, schema: deploy/sql/hidden11-events.sql). When unset the endpoint accepts and discards, so the game is unaffected.

Optional daily-reminder env vars:

• VAPID_PUBLIC_KEY: application server key served by GET /api/push (pass show hidden11/vapid-public-key)
• N8N_PUSH_WEBHOOK_URL: n8n webhook that stores push subscriptions (workflow: deploy/n8n-push-subscriptions.json). Sending is deploy/n8n-daily-push.json; the VAPID private key never leaves n8n (pass show hidden11/vapid-private-key).

Optional search-verification env vars:

• GOOGLE_SITE_VERIFICATION: token for the google-site-verification meta tag. hidden11.app is already verified by DNS TXT, so this is only needed for a second property.
• BING_SITE_VERIFICATION: token for the msvalidate.01 meta tag

Optional social-proof counter env vars:

• N8N_PLAYS_WEBHOOK_URL: n8n webhook URL backing the daily play counter shown on the result screen ("N people played today"). The webhook receives { action: "get" | "increment", date: "YYYY-MM-DD" } and must respond with { count: number }. When unset, the counter line is simply hidden — no number is ever fabricated.

Optional sponsor env vars:

• NEXT_PUBLIC_SPONSOR_ENABLED: set to false to hide the sponsor slot
• NEXT_PUBLIC_SPONSOR_NAME: sponsor name shown in the slot
• NEXT_PUBLIC_SPONSOR_TAGLINE: short sponsor copy
• NEXT_PUBLIC_SPONSOR_CTA: sponsor button text
• NEXT_PUBLIC_SPONSOR_URL: outbound sponsor URL
• NEXT_PUBLIC_SPONSOR_LABEL: small label above the sponsor name
