The Premise
Dropped in a strange city. Empty pockets. Just a quiz between you and home.
Your only way forward is what you know. Answer trivia to scrape together bus fare to the next city, then the next, then somehow cross the Pacific. Trade regional souvenirs to get ahead, keep your morale from bottoming out, and satisfy the odd mission for Martha back at HQ. A network of ten eccentric handlers, from Professor Okafor to Chef Isabella to the nature-obsessed AI DARWIN-7, hold the visas that unlock the rest of the world.

Same world. Different game.
Trailmarks for iPhone is not the desktop game on a smaller screen. It's built natively for the phone as a card game: swipe your way from city to city and call the facts true or false, one hand, no globe. The world, the characters and the art come straight from Trailmarks — the way you play it does not. Fully playable offline, so it works on the flight as well as the commute.

Questions
What kind of game is Trailmarks?
Trailmarks is a singleplayer trivia quiz game inspired by Carmen Sandiego and Backpacker I & II. You answer geography and culture trivia while finding an affordable route, by flight, ferry, train or bus, to circumnavigating a living 3D globe of 1,000 real cities.
Is Trailmarks a quiz game or a travel game?
Both. The trivia quiz mechanic funds your travel: correct answers earn the money you need to reach the next city, so quizzing and journeying are the same loop. If you're very ambitious, you can also fund your journey by trading in local souvenirs.
What platforms is Trailmarks available on?
Trailmarks is out now on Steam for Windows and macOS, and on the Mac App Store and Microsoft Store. A separate iPhone game is out now on the App Store.
Is the iPhone game the same as the PC and Mac game?
No. They're two different games sharing a world, characters and art. The PC and Mac game is built around an interactive 3D globe you spin and route across. The iPhone game is a swipe-based card game made for one-handed play, with no globe. Each is a separate purchase.
Is the iPhone game out?
Yes — it's on the App Store at $4.99. It reached #5 among paid trivia games on its launch day.
What languages does Trailmarks support?
Trailmarks is playable in nine languages: English, Norwegian, German, French, Spanish, Portuguese, Russian, Japanese, and Simplified Chinese.
Is there a demo?
Yes, a free demo is available on the Steam store page — try your way through France and Spain before you buy.
The globe is
your game board.
Out now on Steam for Windows & macOS. A separate card game for iPhone is out now. Grab your guidebook and start circumnavigating.
