How Does the Casino House Edge Compare to Sportsbooks and Lotteries?

Casinos deliver the most predictable odds among common gambling choices, with an average house edge of about 5 % on slot machines and roughly 2 % on blackjack when basic strategy is used. Sportsbooks typically charge a 4 % vigorish, while lottery tickets lose more than 50 % of the stake on average. In plain terms, you keep about 95 cents for every dollar spent at a slot, versus just 45 cents on a lottery ticket. So if your goal is to stretch every bet, the casino beats the lottery and matches or beats most sportsbooks, though it still guarantees a loss over time.
