The odds of winning in online Blackjack are primarily influenced by the game’s rules, the number of decks used, and the player's strategy. In a typical game with favorable rules, such as a 3:2 payout for Blackjack and the dealer standing on a soft 17, the house edge is relatively low, around 0.5%, meaning the player has a decent chance of winning in the long run. However, the house edge can increase with rule variations, such as a 6:5 payout for Blackjack, more decks in use, or restrictions on doubling down or splitting. A player's skill in using basic Blackjack strategy can further lower the house edge and improve the odds of winning. On the other hand, poor decisions or lack of strategy can tilt the odds in favor of the house. Card counting, which can sometimes offer an advantage in live casinos, is less effective online due to frequent shuffling or the use of continuous shuffling machines.
