It's identical to 6-5 Bonus, except you get 10,000 coins per credit bet for a dealt royal. This adds 1.54% to the return, which makes it a 98.41% game -- still good for the casino, and lower than the dreaded (by the casino) "full pay".
So someone playing 5 credits at $1 will win $50,000 for a dealt royal, which you would think would be very enticing. Even quarter players would win $12,500 for a dealt royal.
At the same time, there's still the excitement of hitting quad aces or quad 2-4, which retains all of the interesting elements of bonus poker.
The same game could be built upon 8/5 DDB, with a 98.32% return.
Or if they really want to water down the paytable, they could do this with 7/5 DDB at a 97.25% return.
I think this game would be a hit because of the allure of big money without having to play high limits.
