What would happen?

What would happen if during a game of bingo I lost internet connection? Would I be able to claim games back or would it be a case of tough luck? I think some sites halso have an auto dabber if I lost connection for days would it still compete in the games or shut down after a set amount of time?

If for some reason, you get disconnected from the Internet while you are in a middle of a game (bingo, poker, slots), don't panic. you will automatically be returned to the exact point where the game was interrupted, so you can continue exactly from the same point you left off, just like in any game round.

(The computer database records every bet / deal / roll / spin you make)

What happens if you are offline for days and playing against true players? I just wondered whether a person could say switch off as they know they are going to loose a hand?

You would not get the game back I guess.
I have not yet faced such problems yet.

I think you should not panic in an online game , you can always start from where you leave because every step is reocrded
