Good Idea. The house always wins in the end if you play the machines or table games..
The only place a casino doesn't have a mathematical advantage is with sports betting.
Myself? I just put $2 down on the favorite to "show" in a horse race in a race and sports book.
I might only win a couple of bucks but that is just used as a tip for the cocktail waitress bringing me free drinks all day.
Do that on every horse race an you got to drink for free, keep tipped the waitress so she keeps coming around and maybe even made a few few $$$.
Just kickin down some more Vegas knowledge.
