Blackjack is not just the name of the game.
Blackjack is also a hand consisting of an Ace and any 10-point value card.
The point total of these two cards is 21.
Blackjacks are usually paid out as 3 to 2. This means that if you have
placed a $10 bet, you will get paid $15 and retain your original $10 bet.
Beware of some casinos paying out only 6 to 5
in a so-called "Single-deck game".
Casinos occasionally run special promotions where Blackjack pays 2 to 1.
It is worth keeping an eye out for these events, as a 2 to 1 pay-out
dramatically improves your odds of winning money in the long run.
If the dealer also gets a blackjack it is called a push and you will just
get your own bet back.
If it takes you three or more cards to get 21 or if you split cards and
get 21, it is not referred to as blackjack or paid out as a blackjack.
Only if you are dealt 21 points in 2 cards in the original hand do you
have a blackjack.
Blackjack or 21 is the strongest hand and the highest point total.
