Trailmarks is a travel trivia game built on the real world. You answer true-or-false questions about the city you're in, then spend the rewards on a ticket out, limited by what the departure board offers and what you can afford. Your score is the kilometers behind you. The routes are real: flights that exist, trains where there are tracks, boats across oceans. 1000+ cities. iPhone only, $4.99 once, no ads, no account, plays fully offline.
