Do betting systems actually work in Vegas?

Betting systems exist to mitigate risk and let gamblers engage with games of chance by pacing themselves through budgeting, managing odds, and patience. Yet, the question remains: do betting systems really work in Las Vegas?

In this article, Casino Guru takes a look at some of the most popular betting systems and whether they can help you win more when in Sin City.

What is a Vegas betting strategy?

A betting strategy is designed to help players mitigate risk. This usually happens by following specific betting patterns, for example, the size of the bet you place, or the incremental increase or decrease over time.

Some systems are "flat," meaning that they do not increase the stake size, but others are progressive. There are still systems that may be based on specific sequences. To best understand some of the popular Vegas systems, we have picked three of the main ones.

Looking for a simple Vegas strategy? Try Martingale

Martingale is the best example of a progressive strategy, and specifically a negative progressive strategy. The strategy is based on a base stake size, which you play around. Usually, this is $1. You must only bet on even-money outcomes, i.e., red/black, odd/even.

The strategy works like this: if you lose your $1, you double down, and you bet $2 on your next hand, spin, or round. If you lose that, you double down again and bet $4.

As soon as you win, you default back to your original stake size, and the system carries on until you have recovered after a loss and decided to stop.

There is no obligation to play indefinitely here. The strategy’s goal is to ensure that every loss is recovered while you also recover your losses.

Does Martingale work?

Just like any other betting strategy in Vegas, it’s hardly foolproof. In theory, doubling down after every loss is a great idea, but there is an actual chance that you will hit the table limit.

The table limit is the maximum amount of money you may bet per single bet, and eventually you will lose enough times to not be able to try and recover your loss. You will also need to carry a very large bankroll just in case. Here is what your wager would look like after ten losses:

Your eleventh play would have to be $1024, but the table limit may have a much lower threshold - and $1000 may be the cutoff. Now, most Vegas tables have high limits, but the base bet size may also be larger, and anything larger than $1 makes it a little riskier to play Martingale.

Fibonacci - Just trust the numbers

Fibonacci is a different beast entirely. It is predicated on a universally recognized mathematical pattern in nature, the Fibonacci sequence. When applied to betting strategies, this is a negative progression. The sequence is as follows:

1 - 1 - 2 - 3 - 5 - 8 - 13- 21 - 34 - 55 - 89

But how does it work exactly? Well, it’s not all that complicated. If you win, you move two steps back into the sequence. If you lose, you move one step forward in the sequence.

You may end the sequence as soon as you default to your very first bet in the sequence - $1. This system only works on even-money bets, such as red/black, odd/even.

If you have been paying attention, you will notice that each number in the sequence is the total of its previous two numbers. Losing repeatedly while using Fibonacci carries a much lower overall financial toll, though, as exemplified by the table below:

The only drawback is that this is a very slow system, and that you would need to return to the original $1 bet in the sequence before you can stop.

Does Fibonacci work long-term?

Fibonacci is a system that will spare your bankroll and shield it against sudden financial spikes that can have potentially devastating consequences. However, it is still a progressive system, and the possibility of stacking too many losses is real. This being said, gains from Fibonacci are incremental; you need to arm yourself with patience, and just like in the case of Martingale, have a decent chunk of bankroll with you.

The cancellation system: Labouchère

Up next, there is the so-called cancellation system: Labouchère. This is an interesting system that will have you determine how much you want to win. Let’s say you would like to win $20, just for the sake of keeping things simple. Then your sequence would look like this:

1 - 2 - 3 - 4 - 5 - 5

To clarify here, you are breaking down the $20 into smaller bets that cumulatively add up to $20. Next, you start betting the first number in the sequence and the last number in the sequence, as their total, or in this case, $1 + $5 = $6. If you win, you cross out both 1 and 5 from the sequence, like so:

2 - 3 - 4 - 5

You now bet $2 + $5 = $7 and lose. You add the $7 at the end of the sequence, and now it looks like this:

2 -3 - 4 -5 - 7

Now, you need to bet $2 + $7, and that is $9. If you win, you cross out the numbers, so it looks like this: 3 - 4 - 5 -7. This system is quite flexible, and you can actually choose what it should look like. Please note that there is no need to split the numbers in a progressive sequence; you can just as easily have 1 - 1 - 2 - 2 - 2 - 3 - 3 - 3 - 4 as your starting numbers.

You determine this yourself, and play as you see fit. You can stop at any time, but it’s best that you play through all the numbers in the sequence until you have scratched them all off.

The Vegas betting systems that "actually work"

While betting systems can be fun and give you a sense of control, they are still fallible and will drive you into a corner sooner or later. This is why Casino Guru recommends sticking to time-tested practices instead.

• Manage your bankroll: Make sure to pace yourself and never bet amounts that would break your bankroll too quickly. This may tempt you into spending more than you originally wanted to.
• Pick good games: Slots are usually the worst games you can pick at a casino in terms of potential return-to-player rate. Remember that betting systems mostly work for even-money outcomes, such as the ones found on table games like roulette.
• Take breaks: Taking regular breaks from gambling will help you be more rational about the decisions you make. Remember not to play for too long without some time off.
• Play for fun: No matter the outcome, remember to keep your good mood up and only play if you feel like you are having fun. Gambling is not meant to help you gain financial independence. Avoid practices such as chasing your losses.
• Remember that all betting systems fail: Sooner or later, a betting system will fail. Do not trust the gambler’s fallacy nor any system, for that matter.

Conclusion: Play the odds but mind the facts

Betting systems are very easy to get into, as shown by the examples listed in this article by Casino Guru. Overall, the systems are simple enough to replicate almost intuitively, and you run a good chance of sustaining yourself over the short term.

However, a loss - defined as a sequence of losses that results in a net loss to your bankroll - may occur at virtually any time, so you need to be mindful of this. Playing with fixed betting systems won’t help you beat the house in Vegas, but it may give you a sense of control and boost your confidence.

Ultimately, gambling is best enjoyed when explored as entertainment. Betting systems can help you stay on track, but they are no way to account for the randomness of the games, and the fact that the house will always win.
