Blackjack House Edge

Learn Blackjack Video Source & Info:

The house edge at blackjack is about one-half of 1%. In the long run, you can expect to lose about that percentage of the total amount bet, for example, $5 per session, where a session is 100 hands at $10 per hand. Note that you can win or lose much more than the average in any particular session.

2019 Update: The Current Blackjack News no longer reports information on games that pay less than 2:1 on blackjack (for example, 6:5 games). Only true 2:1 payoff games are listed. Therefore, you need to be extra careful to make sure you’re not sitting down to a 6:5 game in the casino.

The exact house edge depends on the playing rules in effect. To find out the house edge for a given set of playing rules, go to this website:

Click the buttons to specify the rules, and the “Optimal results” field is updated with the house edge for that set of rules. The house edge ranges from about 0.2% to 0.7% for games that have a 3:2 blackjack payoff. Avoid games that pay only 6:5 on blackjack, which have a house edge of about 2%.

If you don’t know the blackjack rules in the U.S. casino where you plan to play, go to this website:

Scroll down until you see “Current Blackjack News” and click the “Sample Issue” button. This opens the Current Blackjack News sample newsletter. Type Ctrl-F and enter the name of the casino to search for it in the newsletter. You can find out the number of tables, the house edge, number of decks, shuffle point, minimum and maximum allowed bet, and the specific playing rules: blackjack payoff, dealer hits soft 17, double after splitting allowed, and so on.

The blackjack basic strategy decisions vary slightly, depending on the playing rules. To find out the exact basic strategy for a given set of rules, go to this website:

Use the pull-down menus to specify the rules, and the color-coded strategy table is automatically updated with the perfect strategy for those rules.

You might find the perfect basic strategy too difficult to learn. In that case, you can try learning a simplified strategy, such as the Super-Easy, Simple, or Great strategy at

The simplified strategies are easier to learn, but they have some incorrect decisions that increase the effective house edge. The Super-Easy, Simple, or Great strategies are successively more accurate but harder to learn. For example, you can learn the Super-Easy strategy in one hour, but its incorrect decisions will cost you an extra $4 per hour, based on playing 100 hands per hour, $10 per hand.

  1. I understand of course you explained the pure theoretical house edge … I always say the real house edge depends on how stupid somebody plays … the house edge is 1) the theoretical house edge (a built-in protection for the casino so that players would not win automatically) , 2) house edge MINUS the player edge and 3) coldness … you have people who lost the total bankrol at roulette and zero didn't fall one single time in for instance 200 spins .. so it was not the house edge here that made them lose ..

  2. I still wish there was more info out there for short-term players. All of this only applies to long term players. I can’t tell you how many times I’m at a 6:5 table and never get a BJ the whole session. Therefore, to me at that moment, there is literally no casino advantage to the 6:5 rule. The statistics didn’t apply to me. Even if I do get a BJ, I may only have $10 out there so we are talking about the difference of pocket change. Literally the difference of if a gallon of milk is on sale or not. So if my goal was to win $50 that day, who cares if BJ is 6:5 or if the dealer hits a soft 17, or etc. etc. For my 1 trip for a few hours that month with a small bankroll and a small win goal, none of these apply to me. Like quite literally, very real world, they simply don’t apply. Even if I noticed a trend over the course of a lifetime of these trips, we’re still only talking about a few dollars.

  3. Wow this is some garbage for stupid people all right. Who the love would need to spend a day learning basic strategy? Time to learn should be 3 minutes. Time to learn card counting isn't a year. Try 30 minutes. And that's IF you memorize the table of what I call "advanced strategy" and what some call "deviations" to basic strategy. If you just do counting with basic strategy, it should take no preparation at all other than just memorizing basic strategy. It's about as hard as playing tic tac toe.

  4. No correct I was a dealer and most people lose more than 5 dollars an hour off 10 dollar bets also people are being mislead the house edge is closer to 7 or 8 percent which explains why so many people lose a few hundred dollars in just a few hours
