Use the full-screen button in the subway typing game when you want to focus on the route map and the next station. It reduces browser distractions and gives the current route, progress, and answer box more room.
How to open the subway game in full screen
Choose a city and line, then select the full-screen button at the top of the game. The current station, next station, progress bar, and typing field have more space, which can make a long route easier to follow.
Use the same button again or your device’s usual full-screen exit action to return. Availability and behavior can vary slightly by browser and device.
A simple way to focus on subway typing
Aim for an accurate completion before chasing time. With fewer tabs and alerts in view, it is easier to spot the sections where station order interrupts your rhythm.
Try the same line again after a completion and compare typos and time. If you stop at a transfer or a long station name, check the stations on either side on the map before another run.
A subway game does not replace live travel information
The game is for practising station names and route order. Before travelling, check official operator notices and station signs for destination, express stops, and service changes.
Once a Seoul line feels familiar, choose another city for a new challenge. Full screen is simply a viewing mode that helps you focus on any selected city and line.
