Blackjack is the most popular casino card game in which you play against the house. It is simple, yet exciting and combines skill and luck which makes it a favorite all over the world. In this section on Blackjack Geeks, we explain the rules, main scope and the flow of the game. Usually, there are some variations of the way blackjack is played, but the core remains the same and that’s what we’ll introduce here.
When you are playing in a live casino, there are specific hand signals you could use to show what your next action is. When blackjack is played with one or two decks, the cards are dealt face down and you can hold them in your hands. When the decks are more, the cards are dealt face up. Depending on that, the hand signals are as follows:
if the cards are face up, just tap on the table with a finger. Otherwise, you have to lightly scrape your cards to the felt;
if you’re playing face up, just wave your hand horizontally. If the cards are face down and in your hand, put them on the table and under your bet to indicate that you don’t want more cards;
if you playing face down, leave your cards on the table face up and then put an additional bet behind your initial wager. The second step applies to face up games as well. There is an exception here: if you have a pair, hold up your index finger to show that you don’t want a split, but a double;
in case you want to surrender in a face-down game, put your cards on the table, face up. After that, no matter the game, slide your index finger horizontally behind your wager. The slide should be longer than the one for hit, about 15 cm/ 6 inches or so. It is ok to also just say “surrender”, especially since some dealers might be unfamiliar with the signal.
the signals here are similar to the double. If you are playing a hand-held game, place your cards face up on the table. Then put your second bet next to your first one (and not behind as when you double). If you have a pair of fours or fives, it is appropriate to show a V sign with your fingers to confirm that you are not doubling, but splitting;
As most popular card games, blackjack has lots of possible rule variations. It is important to examine the rules of the online or offline casino you play at, as it will influence your payout ratio. You need to adapt your strategy to the rules. Before we get that far, we want to introduce you to the most common rules variations in online casinos:
