Slots are better to play physically than slots online, all games actaully even the dice are better played off line.
What makes offline slots better than online?
I have never play offline slot, but I used to watch video in youtube about some people play offline slot but I do not think it is better since they need to move from one machine to other machine to play different slot.
On the other side, online slot gives you easier way to access so many different slots and you can stay in your chair without moving.
