Some video poker machines with jackpots can actually end up becoming +EV, or in other words you win money (in the longrun) with each play. The immediate payout rate for many of these machines is already quite high with a house edge < 1% given optimal play, so in other words on a $100/play game you'd really be losing less than a dollar per play on average even without any additional incentives. Factor in hotel comps, and it can be +EV even without jackpots. Wagering $100k would only be a house edge of ~$800.
