There are two main types of betting systems for blackjack or any casino game—positive progressions and negative progressions. With a positive progression, the general theory is that you raise your bets after wins, which means that your bigger bets are primarily funded by money won. The only way to increase your expectation is to use a 1-10 unit bet spread, which is sure to get you kicked out of any casino eventually. Still, as long as you can get away with a 1-10 unit spread, you can play with an edge of about 0.57%, or about three and a half times greater than with a 1-5 unit spread. Any time the count is a minus number or zero, make a bet of one unit. When the count is positive, bet more than one unit. By betting more when you have the edge, and less when you don't, you can actually beat the casino at blackjack. Of course, you have to practice the count before you ever play for real money. So if you want to increase your bet, you'd be wise to watch the cards as they are played and bet more only after you've seen a fair number of small vs. High cards played in previous rounds. Better yet, learn a simple card counting system, like Speed Count, which will tell you when it's the right time to increase your bet. Never using a casino host.

Blackjack Betting Strategies are quite popular, especially since the game has been featured in hit movies likeRain Man, 21 and The Hangover.
No matter what the game, there is one universal rule; if the casino spreads the game, someone has developed the 'perfect' betting strategy.
Roulette strategies are perhaps the most prominent as roulette strategies and systems have been offered for sale for centuries.
As a dealer and a player, I have been able to see and try many of the most famous Blackjack Betting Strategies.
Blackjack strategies don't change around the world but it is interesting to see different perspectives. A good blackjack resource for Canadians is CanadianCasinos.ca.

The Two Best Systems
There are two strategies that every player should use every time they take a seat at or swim up to a blackjack table.
Play to Have Fun
Napoleon was a fan of Vingt-un (blackjack) near the start of the 19th century. For more than two centuries, blackjack has grown in popularity to become the most popular casino table game.Mathematicians have analyzed the game, hundreds of books have been written about it, and a number of myths and legends have been created.
Earning a place in the Blackjack Hall of Fame at the Barona Casino in California is the only honorary award for players of any casino table game. There is a reason that blackjack has remained popular for a couple of centuries; it's fun! There are many varieties of blackjack. Mr. Green offers a great selection of 15 blackjack games by 6 software providers, including Double Exposure Blackjack Professional Series by Net Entertainment, VIP Blackjack by Extreme Live Gaming, and 6-in-1 Blackjack by Felt.
Spin Palace offers a remarkable amount of blackjack games. There are over 40 blackjack games in total on offer. They also offer practice play which is perfect for sharpening your blackjack skills before you start playing for real money. Most of their games are developed by Microgaming which are very popular in English speaking countries like Australia, New Zealand, UK and Canada.
Yes, the game has a really low house edge, which makes it appealing, but it is a very social game, so in many cases, the table wins or loses as a group. This builds comradery and makes it fairly common for players to talk with one another. The social aspect of the game is a very important one to most players.
Bet the Right Amount

Set up a bankroll before you go to the table. This is your total stake.
As has been mentioned numerous times, blackjack is supposed to be fun. Playing with money you can't afford to lose (what dealers and players call 'scared money') practically guarantees you won't enjoy the game.
It is fairly easy to find table limits to fit most bankrolls.
The Martingale – Blackjack Betting Strategies
Image Source: pokerbankrollblog.com
The Martingale system originated in 18th century France and is one of the oldest systems around. The original theory was used to prove that someone with infinite wealth could always avoid a loss in even money bets by doubling the best after each loss. Most likely the first casino game where the Martingale system was touted was roulette, but it can also be used in other areas, such as in stock market trading.
You will often see players use the Martingale system at the blackjack table, doubling their wager after each loss. In theory, this strategy sounds solid. However, blackjack is not an even money game. And additionally, players will occasionally run into a bad streak of cards. At a $5 table using the Martingale system if you lose 8 hands in a row, you will be wagering $1280 on your next hand, so unless you are a legendary high-roller, you are probably better off taking the $5 loss.
2-1-2 (Manhattan) Strategy – Blackjack Betting Strategies
One of the common laments one hears from players is the one where they were 'way ahead' but gave it all back. These players are the same ones that usually talk about 'playing with ‘house' money.'
Here is a fact: Once the chips are in your stack, they are your chips, not the house's.
The second most common lament you will hear is a player talking about missing out on a hot streak. The 2-1-2 strategy helps address both.
First, there is no mathematical foundation for 'hot' or 'cold' streaks at the blackjack table. Mathematicians will tell you (truthfully) that there is no such phenomenon. Blackjack players know they exist.
As a player you want to capitalize on a good run of cards and this strategy has some merits. Start with a 2 unit bet. If you win you reduce the bet to one unit. If you win that bet you increase to 3 units. Once the dealer wins you go back to your original 2 unit bet.
A run of 10 hands could look like this:
Wager Result +/-
- 2 W +2
- 1 W +3
- 2 W +5
- 3 W +8
- 4 L +4
- 2 W +6
- 1 L +5
- 2 W +7
- 3 W +10
- 4 L +6
With the 2-1-2 strategy, players will win a bit more with a hot run yet not sacrifice all of their winnings.
Oscar's System – Blackjack Betting Strategies
Oscar's System was proposed in the 1960's in a book by mathematician Dr. Allan Wilson. It is a fairly decent system. The goal of the strategy is to win exactly one unit per series.
The player starts a series by betting one unit. After a win, the player adds a unit; after a loss, the next bet is exactly the same as the previous one. That's it.
Here are two examples:
Wager Result +/-
- 1 L -1
- 1 L -2
- 1 W -1
- 2 W +1
Series complete
Wager Result +/-
- 1 L -1
- 1 L -2
- 1 L -3
- 1 W -2
- 2 L -4
- 2 W -2
- 3 W +1
With the 2-1-2 strategy, players will win a bit more with a hot run yet not sacrifice all of their winnings.

Playing Multiple Spots
Many players feel that playing multiple hands increases their odds of winning. Playing multiple spots can be exciting, but it does absolutely nothing to increase your win rate.
Most of these systems fall under the heading of progressive bets. While these are among the most common, they are by no means the only strategies out there. It is perfectly fine to sit at the table and make the exact same wager every hand. While this strategy is a bit boring for me, if it works for you that is what counts. There is absolutely nothing wrong with taking out a deck of cards and developing your own strategy as well.
Blackjack Betting Systems in the Long Run
Ok so we've covered the popular blackjack betting systems here and highlighted how they are used but are any of them really useful in the long run? The answer is a resounding NO (this article goes into great depth as to why).
While you might make great short term wins, any betting system will not be a formula for success in the long term. To truly gain an advantage against the casino you must start with learning basic strategy and then moving to card counting.
There are plenty of resources to get started. We recommend:
- BlackjackInfo's Blackjack School – A comprehensive free resource that covers both basic strategy and card counting principles.
- Blackjack Apprenticeship – Run by Colin Jones, a professional counter who featured in the blackjack documentary Holy Rollers, this site provides a paid course offering video training material, private coaching and more.
- WizardofOdds – The wizard has some great strategy charts but only for 4-8 decks. If you need more customized charts then BlackjackInfo has a good strategy chart builder.
- HolyMolyCasinos.com – Offers a how to guide on the rules and how to play blackjack as well as other popular casino games.
Members Feedback
I recently read an article where someone asked for advice on changing your bet size while playing slots. The idea was, when you get ahead, you raise your bets to try to hit a bigger win.
Over the years, I've also seen questions about betting more when you're losing to try to make up for past losses when you hit a win.
These look like two different questions, but they're actually the same question. And the answer should be the same to both questions.
In the article I just read, the answer was decent, but it didn't cover the real reasons in enough depth. Anyone asking either of these questions doesn't understand how slot machines work. They also don't really understand how expected value and long term expectation works.
Slots and Expected Value
When Should You Increase Your Bet In Blackjack
Every slot machine in existence, whether located in a casino or online, has a built in house edge. The house edge is how the casinos make money, and it's impossible to legally overcome the house edge on a slot machine in total. What I mean by 'in total' is that slot machines make money collectively.
A few players win more than they lose in the short term, and a few lucky players win a big enough progressive jackpot to come out ahead. But overall, the slot machine industry is wildly profitable.
Expected value is a term often used in gambling that is a way to express the value of a betting decision. It's used most often in poker to determine the best way to play a hand in a certain situation. You can also use it in games like blackjack to determine the best way to play a hand.
In games like poker and blackjack, you can make strategy decisions based on expected value. Bets on slot machines also have an expected value, but they're all negative. A negative expected value means that, on average, you're going to lose money.
When Do You Raise Your Bet In Blackjack Winnings
Here's an example of expected value on a slot machine.
If a slot machine has a house edge of 5% and you bet $1 on every spin, the expected value is -.05 per spin. On an individual spin, you might lose your entire $1 or win something, but the expected value is the amount you expect to lose on average over thousands of spins.
Expanding this example, if you make 500 bets in an hour, you're expected value is -$25. In other words, you can expect to lose $25 an hour playing this slot machine. Once again, this is an average, so in any single hour, you can lose more or win.
The house edge is the same whether you bet $1 or $100 per spin. It's also the same if you lost the last three spins or won the last three spins. The house edge doesn't change, so changing your bet sizes doesn't help you win more often.
Slots Long Term Expectation
This is going to sound similar to what you learned in the last section because it's closely related. The mistake many slots players make, like the ones asking the two questions in the opening section, is thinking past results in some way change future results.
But, if nothing you can do changes the house edge, how can you believe that you should raise your bets after a losing streak or after a winning streak?
The belief is that because the long term results must come very close to equaling the expected results that there must be a correction one way or another after a winning or losing streak. But the problem with this is that the house edge and expectation are based on a large number of outcomes.
Instead of it being based on 10 or 100 spins like many players act, it's based on hundreds of thousands or millions of spins. Even if you win 10 spins in a row, it doesn't change the odds of what's going to happen on the next spin because the machines are based on such a large number of spins.
I'm trying to show you why without getting into complicated mathematical principles, but you can run the math on the effect of short streaks in large pools of results to prove what I'm saying is true.
When Do You Raise Your Bet In Blackjack Real Money
The belief many players have about short term streaks is made worse when they guess correctly about the next result after a streak. This reinforces what they want to believe, even though the math shows it isn't true.
If you win 10 spins in a row, what do you think is most likely to happen on the next spin? Some players say a loss, because the machine is due for a loss. Other players say a win, because the machine is hot. How can both opinions be true?
When Do You Increase Your Bet In Blackjack
The fact is that neither opinion is true based on why they think they're correct. The true chance of a win or loss is 100% based on how often the machine is programmed to produce a winning spin.
Is It Ever Correct to Alter Your Slots' Bet Size?
When I play slots, I operate in what I call the 'jackpot or bust' mode. I set aside a bankroll to chase a jackpot and keep playing until I either hit a jackpot or run out of money. Most of the time, I run out of money, but every once in a while, I get lucky and hit a small jackpot.
I know that, in the long run, I'm going to lose unless I hit a big slots jackpot. I'm okay with this, just like I'm okay with buying a lottery ticket chasing a big prize. The odds of winning are low, but I'm willing to risk a set amount for the chase.
I always bet the minimum amount on my chosen slot machine that allows me to qualify for a jackpot. I tend to look for machines that have a low bet threshold to unlock the jackpot, because I want to take as many spins as possible.
If you buy a lottery ticket, do you ever spend more money than the ticket costs? Do you give the store clerk $5 for a $3 ticket and not expect to get your $2 in change?
This is how I feel about betting more than I need to while playing slots. This is why I never bet more than the minimum to qualify for a jackpot while playing slots.
The question of changing your bet size while playing slots has two answers. The first answer is if you're betting more than the minimum, then you should bet less. The second answer is that it doesn't matter if you change the size of your bet for any other reason. As long as you understand that the more you bet the more you lose, you can do whatever you want. It's your money, and you can play any way you like.
Conclusion
You're welcome to change the size of your bet while playing slots any time you like. It doesn't matter if you're winning or losing, changing the size of your bet isn't going to alter your chances to win. The only thing that matters is the house edge you're working against and the average bet size of your wagers.
When you bet more after a win, you're just going to lose more in the long run. When you bet more when you lose, you're just going to lose more in the long run. The only way to lose less money playing slots in the long run is to bet less.
The best way to lose less playing slots is to stop playing. But that's not much fun, and you're never going to hit a jackpot if you don't play. I don't recommend that you stop playing. But use smart money management so your bankroll lasts as long as possible and you have the best chance to hit a jackpot before you run out of money.
The only way you can possibly come out ahead in the long run playing slots is to win a jackpot big enough to cover all of your previous losses. This doesn't happen often. The best chance to do this is to make the minimum bet that unlocks the chance at the jackpot and hope for the best. Changing your bet size isn't going to help in the long run.
