Intro to Online Blackjack

Here's the core concept: The aim of Blackjack is to reach a total of 21 with your cards. The classic version 21 Online Blackjack is played with a standard 52-card deck. Number cards retain their face value, face cards count as 10, and aces can be 1 or 11. Without exceeding 21, the player whose cards sum highest wins. If there's a tie, the player with fewer cards wins.

In money-based Blackjack games, players place bets first, then receive two cards along with the dealer. After reviewing their hand, a player can “hit” (get a card), “double” (increase the bet, get one card, end turn), “stand” (end turn), or “split” (divide two matching cards into separate hands and double the bet). When you play Blackjack online, you’re facing both the dealer and fellow players.
