An old favorite gallops back into the winners' circle, finishing ahead of the Rio by a nose. A longtime single-deck mecca, the Horseshoe has added more shoes at its blackjack tables, but there's still plenty of one-shuffle-at-a-time action for the traditionalists in the gambling crowd -- and the number- crunchers who know that fewer decks equal better odds in the endless quest for a perfect 21.
Our Pick: SLOTS A FUN
2880 Las Vegas Blvd. South
Go ahead, laugh. We're hardly wizards of odds around here, but we are reporters -- which means we know who to ask for answers. The response we received is the humble Slots A Fun, which at last check had three low-stakes tables featuring the old Strip game: single-deck, dealer stands on soft 17, with doubling down allowed after a split. On a purely mathematical basis, that adds up to an advantage of .13 percent -- for the player, not the house. And what other casino can make that claim? The only one that comes close, the Westward Ho, eliminates the double-down option for a break-even percentage.
