If you're so inclined you can buy a slot machine program and save yourself a ton of money. As WOPR said in War Games: "The only winning move is not to play." But if you'd still like to gamble just to gamble there's a hilariously dated set of books by John Scarne you may want to read. Try Scarne on Dice or Scarne's Complete Guide to Gambling. He does a decent job of explaining the rules to then common casino games including a layman's introduction to probability and payouts. The most entertaining part of the books is his language: he writes in the same dialogue used by gangsters in 40s movies. The books can be found on the cheap in garage sales or at Half Price Books.
