‘Blackjack’ is when you get 21 with only 2 cards, meaning you’re dealt an ace and a 10, J, Q, or K. If you get 21 with more than two cards, it’s not a ‘Blackjack’, but simply a hand valued at 21. Only a true ‘Blackjack’ hand will give you the extra payout for this combination of cards, which is normally a 3:2 payout.
