9/6 refers to the paytable payoffs for a full house (9) or flush (6). A 9/6 Jacks or Better game is considered to be "full pay" in that the house advantage is very small.
Most video poker games use the full house / flush payback to adjust the house edge so that two number reference is often used as shorthand to describe the games.
You will have a very difficult time finding any 9/6 video poker games at any Harrahs
casino in Vegas - or anything close to it for that matter. I saw one 9/6 machine in the high limit room at Paris
- if you are willing to play at a $5 machine ($25 per hand max credits). 7/5 Jacks seems to be the norm in Vegas with alot of quarter machines set at 6/5.
Recent reports have indicated that Planet Hollywood
has 8/5 bonus poker - which is the full pay version of bonus poker.
