The only time I ever walk into a casino is on a cruise. I consider it just another form of shipboard entertainment. The only game I play is blackjack, since the house edge on this game is very small, and the cost over the long run is low.
On my HAL cruises, BJ was dealt from an eight deck shoe, double down on any two cards, split pairs three times(except aces), double after splitting, and dealer stands on all 17's. With these rules, the house edge is minuscule 0.47% if you play correctly. Over the long run you get a lot of play time for low cost. Of course, bad play will significantly increase the house edge.
