It's rush hour on a packed subway car, and every seat is taken. Your job: read the little tells, figure out who's getting off at the next stop, and be standing right in front of them when the doors open. Putting a phone away, setting a bag on the lap and gripping the handles, glancing up at the station sign... The tells get clearer as the train pulls in, but wait too long and a rival rider beats you to it.
You have four stops to land a seat. The earlier you sit, the higher your score, and you earn a bonus for every second you were already waiting in front of that seat before the train arrived. Watch out for riders who aren't going anywhere, like the one who pulls out a book or the one who's fast asleep and about to miss their stop. See How to play for the full rules.
On Today's Line, everyone gets the same riders and the same tells for the day, so you can share your result on X or any app and compare. No sign-up, no download: it runs right in your phone's browser.
