Frequently Asked Questions
What is the house edge in blackjack?
With perfect basic strategy, blackjack's house edge is typically between 0.3% and 0.7% depending on table rules, meaning the casino expects to keep that percentage of total wagers over time.
How does strategy accuracy affect the edge?
Every deviation from basic strategy tends to add to the house edge. Players who play imperfectly often face an effective edge 1-4% higher than optimal play.
What does standard deviation mean here?
It reflects the natural swing in outcomes due to variance. Even with a small house edge, a single session's result can vary widely above or below the expected value.
