The house advantage in blackjack typically ranges between 0.5% and 2%, depending on the rules of the specific game and the player's skill level. This advantage comes from factors like the dealer acting after players (causing players to lose even if the dealer busts later) and rules on blackjack payouts, splitting, doubling down, or whether the dealer hits on soft 17. Proper strategy by players can minimize the house edge, but it always ensures a slight long-term advantage for the casino.
 
That's a very accurate analysis of the factors contributing to the house advantage in blackjack. The house edge can vary based on the specific rules in place, as you mentioned. For example, games where the dealer stands on soft 17 or allows players to double down after splitting tend to have a lower house edge compared to games with less favorable rules for players.

Additionally, the key to reducing the house edge as much as possible for players lies in using basic strategy. This strategy, derived from computer simulations, dictates the statistically best decisions to make based on the player's hand and the dealer's upcard. By following basic strategy, players can make more optimal decisions in the long run, thereby minimizing the casino's advantage.

While the house always has a slight advantage in the long term, practicing solid basic strategy and being aware of the rules of the game can help players maximize their chances of winning and enjoy the game of blackjack to the fullest.
 
Players only see one of the dealer's cards when making their decisions. This asymmetry of information means that players must make strategic choices without knowing the full picture, while the dealer plays with complete knowledge of their own hand and the player's actions.
