Odds are, these tips may help you steer the course. Getty Images By Ryan Ermey, Associate Editor From Kiplinger's Personal Finance, August 2017 In the field of personal finance, gambling is considered a bad idea. Each game in the casino comes with a “house edge” — a greater probability that the casino will win and you will lose. If, despite the tilted odds, gambling appeals to you as entertainment (come on, it’s Vegas!), at least vow to play only with money that you’re fully prepared to part with.See Also: 31 Best Travel Sites to Save You Money “Think of it like going to a show or a sporting event,” says Steve Bourie, author of the American Casino Guide (Casino Vacations Press). “At the end of the night, you probably won’t have anything to show for it other than the experience.” Before you approach a table or a slot machine, sign up for the casino’s rewards program either at the on-site rewards desk or online. You’ll receive offers for free or discounted stays and presale tickets for shows. You’ll also receive a player’s card, which you present to your dealer or insert into your slot machine before you begin play. The more you bet, the more points you’ll accrue, which can be used for shopping, dining and hotel stays, among other perks. To maximize rewards, concentrate your gambling at one casino per trip. If you’re bringing a spouse, you should both gamble under one card to maximize rewards as well. Advertisement Boost the odds. Stick to bets that offer you the best chance of winning. For blackjack, make sure your table pays 3-to-2 when you’re dealt a 21 (some single-deck games pay 6-to-5, which quadruples the house edge). You’ll maximize your odds if you play “by the book” — always making the mathematically optimal choice. Most casinos sell blackjack strategy charts at the gift shop (and will let you consult them at the table as long as you don’t hold up play). You can find free printable versions online as well, including at Bourie’s website. The site also offers tutorials on table games. Craps and baccarat, whose basic-bet odds are among the best in the casino, are worth learning. Slots are generally a lousy bet, but at least avoid cheap machines and fancy casinos. On the Strip, penny slots pay an average of 88 cents for every dollar gamblers put in; quarter slots, by comparison, pay 91 cents. Avoid the Strip and your odds improve: Quarter slots pay an average of 97 cents on the dollar at local casinos, such as the Fiesta Rancho in North Las Vegas.

If you win more than $1,200 at a slot machine or $1,500 at keno, you’ll be issued IRS Form W-2G, and the casino will likely take 25% of your winnings to give to the IRS before paying you. Otherwise, you’ll report your winnings as “other income” at tax time. If you itemize, you can deduct your losses — but only to the extent that they offset your winnings.
