This differs from online casinos, though, as they usually have a range of blackjack variants to suit different tastes, so it's easy to find titles that have this side bet. In a physical casino, you need to look out for a 21 + 3 box on the table where the game is taking place.
Not all blackjack sessions will allow the side bet. Your first step is to find a table that plays the game. Essentially, it involves playing blackjack and a three-card game of poker at once. Though it sounds confusing, for anyone with a grasp of poker it can be a very enjoyable additional wager. When playing games of Blackjack, either in brick-and-mortar casinos or online, you may come across the option to play Blackjack that involves a 21 + 3 side bet.
