TIDELINE is not a fixed-route transit puzzle. It is a live network strategy game where the city keeps moving while you redesign it.
Extend either endpoint, drag the middle of a line to insert a new stop, undo an endpoint, or connect both ends to create a true loop line.
Drag a train to another segment or another unlocked line. Choose its position and direction while every onboard passenger stays with the train.
Stations generate shape-based destinations. Transfers form only where lines share a station, and congestion grows when a district is ignored. Split overloaded corridors, repair disconnected gaps, and use Express Waves at the right moment.
Grow from the first three stations into a 12-station coastal city with five lines, river crossings, tunnels, transfer pressure, and level-specific service goals.
Daily Cities do more than rearrange a map. Their seeded rules change train capacity, tunnel limits, demand surges, river-crossing speed, and Express timing for a focused three-minute run.
Every campaign level and Daily City is fully playable without ads or purchases. Optional rewarded ads and consumable gem packs unlock cosmetic line themes only; they never change train speed, capacity, demand, or scoring.
Switch between English and Korean in Settings. Your privacy choice never blocks gameplay.
