I have no idea. What I do know is this is the only casino I've ever played at where I had multiple bad beats in a night, and it happened on two separate nights at the same casino. Gave them a quick 1 hour 2nd chance, and when it happened again I took off and never went back.
I also have never been dealt so many great hands in one night anywhere--ever. Yet, still falling short to slightly better hands. At the same time, watching other players at same tables go heads up with huge bets and winning with Jack high.
Also, they have posted a sign about prop players (which they use to keep at least 2 tables rolling for 24/7), and when I requested for them to point them out, well, only me and 2 others were visiting that Tuesday at 1am. I'll give you 2 guesses on which players were winning the pots over and over--not us visitors.
What I found even more interesting was what these people were calling with on the flop, which in most occasions was nothing (calling and making huge bets on runner-runner draws), then almost every time catching just enough on the river to pull off a win. Over and over.
Another thing that I didn't like was I hit a high hand in the off hours (AAAQQ), and then after waiting 1 hour, the 30 seconds before they were to give me my high hand win, they announced it was beat by AAAKK. However, we were only 2 tables, and it didn't happen at our table. I asked other table, and everyone played dumb. No one was awarded the high hand money. I watched carefully, and when I asked the poker room attendee what happened, he just said, "bad luck, I guess."
Now, I've lost many high hands in the final minutes--that doesn't bother me. But, no one was paid for that one, and they basically robbed it openly far as I could tell.
I went to another casino after those beats and did fine as normal and thankfully did well enough to cut even for the night's losses.
I am not one to accuse any game room of having poker room cheating, but if they are good, there's likely no way we'd catch them. I have always been skeptical and heard stories--which I always defended the poker rooms and said they don't need to cheat--they make plenty.
Maybe I am wrong. Chances are, I just coincidentally had really bad luck only at that location; on the other hand, it doesn't mess with me mentally as much if I can imagine I simply got punked. I think I'd prefer that more, lol.
