Some casinos have moved this down to 6:5 or 7:5, however, this means you’ll get considerably less money over the long haul. That means you win $300 for every $200 bet at 3:2, or $200 for every $100 bet at 2:1. If you get 21 points exactly on the deal, that is called a “blackjack.” When you’re dealt a blackjack 21, it’s customary to pay out 3:2 or 2:1. The most important blackjack rule is simple: beat the dealer’s hand without going over 21.
