On a very smaller scale, Casino Royale on the strip has a 20% rebate for machine play.

They have a $20 100% rebate for new players, that most people know about, but they also have a 20% loss rebate for returning players.

So you can go in on Monday lose $100 and get $20 back for a net loss of $80. Then go in on Tuesday and win $100 and keep the $100. In theory big player advantage. Unfortunately after collecting the rebate twice, they usually put an end to it, even though there is no written rule limiting usage.

Silver Seven had a similar rebate back when they were still Terrible's for table games. It was also 20%. Go in one day and play blackjack and lose $500 and you get $100 back for a net loss of $400, The next day if you win, $500, you keep the entire amount. Again, big advantage player. But just like Casino Rpyale, the stopped paying out the rebate after the second time, even though there was no written rule limiting the number of times. They just point to small print that says something about "at the casino's discretion".

Now I believe Silver Severs rebate is only 5% and is good on your monthly losses, although I don't bother with it, so am not sure.
