RD, you have just about covered it. Very occasionally a progressive slot machine will have a high enough jackpot such that it will have a positive expectation if played correctly.
Forget about the baccarat advice. The odds will always favor the casino no matter what.
In Baccarat the dealer deals 2 hands “Player” and Banker" the banker has a slight advantage, but one must pay "commission to the house when betting on “Banker” and Banker wins. There is also a system to craps. Always bet the maximum allowable odds, thereby reducing the house’s advantage. It will never reach 1 to 1, but close. In blackjack, the larger number of decks in the shoe the more effective it is to count cards. When the deck is “10 heavy” the odds are in favor of the player vs: the house, so it’s time to increase your bet. When the shoe is re-shuffled, one must start counting all over and wait for the 10 heavy deck. A good book is “Winning Casino Gambling” (forgot the author)
