Games for a long flight

The long-haul flight is the last honest test of a mobile game: no connection, no notifications, nothing but you and the thing you actually bought. Free-to-play games fail this test at the first energy meter. These six don’t — every one runs fully offline, and together they cover the whole flight: a puzzle box for the climb, transit maps over the ocean, and a border checkpoint for that final delirious hour before descent.
