Welcome to multi-hand Single Deck Blackjack.
This variant is played with a single deck of cards, unlike standard Blackjack, which is played with 6 decks. Each player plays only against the dealer (i.e. the bank), independently of other players. Your goal as the player is to draw cards (i.e. hit) until your hand adds up to 21, or comes as close as possible without exceeding 21.
If your first two cards total 21, you have Blackjack!
