There’s a bit more nuance to playing blackjack, as you might have guessed, so we’ll cover it as simply as possible below.
If you get a lower score than the dealer does, you will lose. If you go over 21, you will automatically bust. The aim is to get as close to 21 as possible without going over. Blackjack, also known as 21, is a game played against the dealer (rather than other players).
