Some games can get large enough jackpots to make a game +EV. Doesn't mean the house would lose. The advantage players would fight for the machine(s, if a pooled jackpot) and play until the jackpot was hit, at which point it would become -EV again and they would stop. These machines are relatively uncommon, and getting more uncommon. You can read about these players, I think they can squeak by making about minimum wage or thereabouts.
