Craps offers bets with a house edge as low as 1.41%, but it also offers bets with a house edge as high as 16.67%. You should know which bets offer reasonable or better odds and which bets offer outrageous odds.
Blackjack comes with multiple rules variations, but the biggest is the payout for a “natural”. The standard payout for a 2-card hand totaling 21 is 3 to 2. But some casinos offer a 6 to 5 payout on his hand.
And with their usual chutzpah, the casinos try to make this sound like a good deal. But if you place a $100 bet, the payout at a 3 to 2 game is $150, compared to a payout of $120 on the same bet at a 6 to 5 tables. This requires a little bit of study before visiting the casino, but feankly, id doesn’t require much.
