From the Aquarius site, explaining how to play Blackjack:
"Played for generations, our casino proudly offers three varieties of
Blackjack to increase your gaming options Single Deck 21, Double
Deck 21 (dealt by hand), and Multiple Deck 21 (dealt from a box
called "the shoe")."
"Should your count total 21 on your first two cards, you have a
blackjack and the dealer will pay you one and a half times your wager.
If the dealer also has a blackjack, it's a push."
