I just came back from an Indian Casino where I suspected something was up with the Video Poker for a while now, for my experience there playing VP is very different than playing in Las Vegas (and it is nothing to do with the pay tables). What is going on is that that Indian Casino is that they are simply returning the discarded card back to the deck rather than removing them. I noticed this when I got 4 to a straight flush (all hearts) on a JOB 9/5 machine with a King of of spades sitting in the center of the deal. Since I was down quiet a bit I took notice particular of this hand, so I selected my four hold cards (all the hearts) and then pressed the draw button. The Kink of Spades flashed but did not go away, and I lost the hand. I sat there stunned and realized that I had seen this before, where a discarded card comes back, but my mind at those did not really register that was in fact what was happening. Returning the discarded cards back to the deck to be drawn from can indeed give the illusion that there is more than one deck at play, as players may claim. The Wizard of Odds publishes the rules for VP here http://wizardofodds.com/games/video-poker/basics/#toc-Rules However, in Oregon the Indian Casinos are 'self-regulated' and they can do whatever they want with the games with impunity. If they chose to return the discarded cards back to the deck, this does obviously increases house edge by: You will get more 2 of a kinds and slightly more full houses, but the odds then for the 4-kinds, straight flushes and royals goes way up. If you need an excuse to NOT PLAY video poker at a tribal casino, this is it then.
