Each of the 90-plus rounds gives you a shrinking window — 12 seconds at the start, down to 2.5 by the end — to click a seat before the train car finishes scrolling past. Scoring runs -5 to +5 per pick: an empty window bay is the top prize, sitting near a “red” passenger costs a flat -4, an orange manspreader wedged in next door is -2, and a purple passenger blasting music docks the whole half of the car. A very specific, very German anxiety, gamified.
