These answers point to a useful pattern: good mobile strategy doesn’t have to be simple, but it does need to tolerate interruption. Unciv removes real-time pressure, Into the Breach preserves a run cleanly, Landrule compresses a full match, and Arknights keeps stages short. So the better test may be: how quickly can you return to one meaningful decision after unlocking your phone? That seems more useful than judging by genre alone.
