There is a big difference between blackjack and 21. Blackjack is a game of chance where players make choices regarding how many cards to draw and hold.
21 is a more strategic game where players bet on the number combination that will be drawn. .
There are also some key differences in the rules of play between the two games. Blackjack has a fixed number of decks, while 21 has an infinite number of decks. In blackjack, the dealer deals one card face down, then turns over another card. The player must choose whether to keep or replace the original card(s).
If the player replaces the card, that card becomes their new hand and they must new decide whether to take another card or hit. If the player hits, they receive two cards from the dealer and add them to their hand. If they keep the original card, they add it to their hand and draw another. The player’s goal is to either get a “blackjack” (a total of 21), or get closer to a blackjack by drawing additional cards until they get there.
In 21, players bet on any number between one and 21. The number that is chosen becomes the first number in a new sequence.
For every number after that, the player must subtract 1 from the previous number in that sequence (for example, if someone bets on 5, 6, 7, 8 and 9, the next number in that sequence would be 4). After all nine numbers have been played, the player would then win if any of those numbers was drawn (for example if someone bets on 5-9-1-6-8-4 and 4 was drawn as an outcome, they would win).
