Last time I was in Vegas (October 2014), I had a few hours to kill and was staying at SLS, so I walked down to Riviera and played $1 blackjack. This was the first time I played $1 blackjack and I got really bored really quickly. I found that I ended up playing $5 hands which is what I usually do. I noticed that they collect the cards and feed them back into the machine and they, presumably, get reshuffled in there straight away. I'm curious to know how this affects odds vs. other tables where they play multi-deck but the cards played aren't added back into the mix. I did horrible at the Riviera. Could have just been me: I was taking lots of crazy (but fun) risks because the stakes were low. But somebody mentioned in passing that I should never play at those tables. The odds are greatly reduced when the cards are put back in the pot and reshuffled. Any insights here?
