I just found out that there are still a few -- and just a few -- 9/6 Double Double Bonus machines at Rincon up to the $5 level, and at $1 on the low end.

This came as a surprise to me, because I thought all of the 9/6 and 9/5 DDB machines were replaced by an 8/5 paytable.

To find the few remaining 9/6 DDB look for the old round-top, upright VP machines in the video poker room.

9/6 DDB is considered "full pay" and has a payback of 98.98% and it actually beats what is available at Caesars in LV where you will find 9/5 DDB.
