Free to download, with a new Daily Journey every day. The full game is a single purchase, no subscription.
Trailmarks is a travel trivia game built on the real world. You answer true-or-false questions about the city you're in, collect the rewards, and put them toward a ticket out. Where you can go depends on what you can afford, what the departure board offers, and how much risk you want to take.
Your score is the kilometers behind you when you run out of nerve or mood. A run usually fits one sitting, though a good one keeps going, and you can put it down and come back whenever.
THE DAILY JOURNEY
Every day, everyone gets the same run: the same start city, the same cards, one attempt. Some days begin where something is happening, like Syttende mai in Oslo or Diwali in Jaipur, and some change the rules. Compare your distance on the daily leaderboard.
1,000+ CITIES, REAL ROUTES
São Paulo, Berlin, Nuuk, Kismaayo. Flights on the departure board are routes that actually exist, and trains run where there are tracks. Crossing an ocean means finding a port and a boat, or saving up for the airfare.
99,000 LOCAL QUESTIONS
Every city has its own true/false deck covering local history, food and culture. The questions are about the place you're standing in, so you end up learning niche local facts whether you intended to or not.
WHEN TO MOVE ON
Each departure is its own decision. A bus is cheap but always depletes your mood. Flights vary with distance. Trains and boats mostly leave you better off than when you boarded, but come at a price. Weigh that against the fare, against how much a city is still worth to you, and against whether you'll ever get this particular route offered again. Staying is usually fine while the trivia is going your way, but a difficult run of topics is a good reason to take the first bus out. Turning down a departure isn't free either, since every declined ticket costs you a little mood.
STREAKS
Consecutive correct answers raise your payouts and lower your ticket prices. Get one wrong and prices climb back up.
UNLOCKABLE STARTING CITIES
Singapore gives you a hub with departures in every direction. Master it and harder openings unlock. Nuuk has one flight out and a handful of sea routes, which is a very different problem to solve.
