How could it have been the full jackpot?
Rule 1 said you can't quit the game at anytime until rule 3 if the majority agreed but the penalty was that the survivors get nothing and that the living relatives of the dead would get 100 million won each. Since most died on the first day and they quit right after, that jackpot should've been less than half the earnings. Unless they were paying extra for just quitting which sounds dumb in itself but I guess if you're filthy rich it dun matter either way.
Update:
Forget this silly post. Figured it out.
