My local casino offers Jacks or Better but it's all 6/5 unless you play $5 per credit, and even then it's only 8/6.
They also offer 10 Double Double Bonus machines that are linked with a royal flush jackpot. The jackpot starts at the standard 4,000 credits and increases based on amounts bet until it's hit. Obviously the higher the jackpot amount, the higher the EV of these machines, but I wanted to run the numbers to find out how much the jackpot affects the payout.
The standard return is terrible without the jackpot since they lower the full house payout to 7 and flush to 5, so it's only 95.7120%. However, the jackpot often increases to 6,000+ credits and have seen it high as ~8,000 which is double the standard payout.

So if the jackpot reaches 8,000 credits, the EV increases by 2.2771%, and brings the EV at these machines to 97.9891% - still not great, but much improved.
If I were better at math I'd try to determine if there is a standard rate the EV increases per credit, but as a general rule of thumb it looks like every 1,000 credits increases the EV about .55%. The higher the jackpot, the higher the increase.
I've also heard of other casinos offering similar jackpots for Jacks or Better, so decided to run the numbers on 9/6:

So the increase was even slightly better. Now if only my casino offered a 9/6 jackpot!
