Casinos do not intentionally let players win at first or manipulate the outcomes of games in order to entice players to continue playing. All casino games are designed to give the house a long-term advantage, and this advantage is built into the rules and payouts of the game.
If you're willing to put in a little work, blackjack offers the best odds. I'm talking about a . 5 percent casino edge, depending on which table you're sitting at. (Meaning for every dollar you gamble, you'll lose only half a penny on average.)
