Got stuck at the airport for almost three hours because of a delay. Saw someone nearby killing time playing slots on their phone, looked pretty straightforward. Didn’t ask them, but it got me curious. Which slots are actually worth trying in a situation like that?

In those situations, I wouldn't choose something complicated with a bunch of bonuses and rules. When you are sitting with a suitcase and constantly checking the scoreboard, something as simple and understandable as possible is better. I once opened https://indian.1xbet.com/en/slots/game/39109/lucky-7 in a similar situation precisely because the format is basic and does not take a long time to understand. A couple of revolutions and everything is clear. For waiting for the flight, this is more than enough, without excessive concentration and stress.
