Subway Idle 3D

Across the map of Subway Idle 3D, empty land fills with stations, rails, and packed platforms as your transit network spreads to new cities. Money rolls in on its own once lines connect properly, while passenger traffic grows with every added route. Experience builds over time and unlocks fresh locations around the world. Mission rewards hand out diamonds for temporary boosts. Gold wagons on the network raise your earnings when they roll in. Daily login rewards add extra cash, and offline income waits for you when you return.

How to play?

At the first stretch of track, press the rail area to speed up the trains and get the network moving. With cash in hand, upgrade subway lines and lay new links between stations to push more riders through the system. After enough expansion, complete missions for diamonds, trigger support bonuses, and level up to reach new maps.
