How do you play blackjack?

Blackjack is a card game, among players and a dealer. Each player is initially given two cards and the dealer shows one card. Each player takes a turn deciding to request one new card, "double down" by taking one extra card and doubling their bet amount, or "splitting" if the player's two cards are identical by doubling their bet and subsequently splitting the two cards into two new games. Cards with kings, queens, or jacks count are considered to have.a value of 10. Cards with an ace can be considered to be either a 1 or 11, whichever benefits the player. The player has the choice to take one additional card at a time to increase their value, until their choose to stop and "stay", or lose the game if their cards total more than 21. Once the player chooses to "stay", the dealer goes through a similar process by taking new cards until they either go over 21 and lose, or reach 17, 18, 19, 20, or 21. The player wins if the sum of the value of their cards  is greater than the sum of the value of the dealer's card. The the players sum of the value equals the dealers sum their value, then the game is a "draw" and a tie. A "blackjack" is when a player's first two cards total 21, and the player typically receives 150% the value of their bet. If both the player and the dealer have a blackjack on their first two cards, then it is considered a tie.
