EARN A POSTCARD FOR EVERY LEVEL YOU PASS

Eight tiers. One-of-a-kind each.

Pass a level, your postcard develops in front of you. Each city has eight — including a gold-foil Pathfinder's Cut and a holographic Legend's Cut you actually want to keep.

PLAY

Trivia written for wherever you're going.

Type a city — anywhere — and the AI writes eight tiers of questions tuned for that place. Start with the basics in noon light. Earn your way to a Legend's Cut under an aurora night. The deeper you go, the better the stories.

THE EIGHT HOURS

Each tier is its own atmosphere. Level 1 plays in noon light with the basics — Eiffel Tower, Seine, croissants. Level 8 plays under an aurora with questions only the locals catch. Tone, palette, depth — all tuned per tier, per city.

COLLECT

Postcards you actually want to keep.

AI-painted for wherever you're playing — Paris, Phuket, your hometown — with a real front and a journal-style back full of the deep facts you earned. Eight collectible tiers per destination, including a gold-foil Pathfinder's Cut at level 7 and a holographic Legend's Cut at level 8.

DEVELOPS LIKE A POLAROID

The earned moment is the moment. Pass the level and the postcard fades in front of you — image, then title, then fact. Levels 1–6 are warm-light reads. Level 7 ships with gold-foil chrome. Level 8 is a holographic Legend's Cut — the kind of thing you screenshot before you save.

  • Front + journal back
  • Gold foil + holo tiers
  • Saved forever in your passport

EARN

A real postage stamp for every city you crack.

Each city you pass earns a hand-painted postage stamp — scalloped edges, country slug, gradient palette pulled from the city itself. Your passport fills the way a real one does: one destination at a time, no two stamps alike.

THE SYSTEM

Same city, same stamp — every time. Your Lisbon stamp matches every other traveler's Lisbon stamp, so a passport is instantly readable. The postcards, though, are AI-painted fresh for each player. Two artifacts, two jobs: stamps prove where, postcards remember how.

  • One stamp per city
  • City-deterministic palette
  • Lives in your passport forever

SHARE

Scan a landmark. Send the postcard.

Out in the world, point at any landmark or notable building. Scan AI gives you the deep story most travelers walk past — then turns that "huh, neat" moment into a postcard or Story your friends actually open.

ADAPTS TO WHERE YOU'RE SENDING

One scan, two formats. Tap Postcard for iMessage, WhatsApp, the group chat — a square hero-card your friends will tap. Tap Story for Instagram or Snap, and pick which facts to feature. Same artifact, different shape, no awkward cropping.
