The 7 Best Roulette Systems to Try (And Why)

Before I list the 7 best roulette systems to try, I need to explain that roulette is  a game where the house as a mathematical edge that can’t be beat in the long run. I explain in a little bit of detail in my previous post, 7 Ways to Win at Roulette, how the math behind the game works.

For the purposes of this post, let me reiterate that the house edge for roulette, in most United States casinos, is 5.26%. This is a mathematical estimate of how much money you’ll lose on average per bet over time. None of the 7 best roulette systems described on this page will enable you to overcome that edge.

But you and I don’t gamble in the long run. Casino gamblers who play roulette care about short term results. And while betting systems don’t work in the long run, they often work surprisingly well in the short run.

Also, some roulette systems are just plain fun to try–even if they won’t help you win in the long run.

Below I list the best roulette systems to try along with the pros and cons for each of them.

1- The Martingale System

The Martingale System is the most famous and popular roulette betting system. It’s used in some other casino games, too. But it’s most famous as a roulette system.

One of the biggest pros of the Martingale System is that it’s easy to implement. You start by placing a bet on one of the even-money bets on the roulette table. These include betting on red or black, or on odd or even, or on high or low.

If you win, great! The system worked. Now you can start over and bet on the next spin of the wheel.

If you lose, you move on to the next step of the system. You place another even money bet. This time, you bet twice as much as you did last time. For example, if you bet $5 on black on the first spin and lost, you now bet $10 on red or black. (It doesn’t really matter.)

If you win, you’re up $5. If you lose,though…

You double the size of your bet again, this time to $20.

If you win, you’re up $5. And if you lose…

The Martingale System is what you call a “progressive betting system”. You bet progressively higher every time you lose. Eventually, when you win, you win back your previous losses and show a one-unit profit.

I’ve already mentioned that the biggest pro to this system is its simplicity. Anyone can figure out how to use the Martingale System. It also works pretty well a lot of the time.

The biggest con with the system is the same as with all these systems:

It doesn’t work in the long run.

Here’s why:

Eventually you’ll have a losing streak that’s long enough that you’ll be unable to place the next bet in the sequence. You’ll either run out of money or you’ll bump into the casino’s betting limits.

It seems horribly unlikely that you’ll lose X number of times in a row, but it always happens eventually. When it does, you’ll lose enough money to make up for all the small wins you’ve had.

Here’s an example of the progression starting with a $10 bet:

  1. $10
  2. $20
  3. $40
  4. $80
  5. $160
  6. $320
  7. $640
  8. $1280

That’s what happens when you have a losing streak that lasts for 7 or 8 spins in a row.

Most casinos have betting limits on their roulette games. If they accept low wagers, like $5 or $10 per spin, they usually cap the betting at $500. You might run into a maximum bet of $1000, too.

Think about this, too:

Suppose you don’t have betting limits. By spin #8, you’re risking another $1280 (on top of the $1275 you’ve already lost), to get a net win of $5.

Sure, in the short run, you’ll often see some small profits using this system. I think it’s fun to do, too.

But the casinos aren’t worried that you’ll put them out of business using the Martingale System. They understand the math better than that.

2- The Labouchere System

Since the Martingale System was so simple, I thought it might be appropriate to follow that up with an explanation of a more complicated system–the Labouchere System.

Like the Martingale System, the premise behind the Labouchere System is that you’ll recoup your losses on previous bets with wins on subsequent bets.

But instead of recouping those losses with a single large bet, you’ll recoup those losses with multiple bets.

The first step in the Labouchere System is to choose a series of numbers. It doesn’t matter what they are, but the potential profit for the betting sequence is the sum of the numbers in that sequence.

Here’s an example sequence to start with:

5, 10, 15

Your potential profit is $30.

When you place your bet, you size it by adding the first number in the sequence to the last number in the sequence.

With the example given above, you’ll bet $20. ($5 + $15).

If you win that bet, you cross the first and last number of the sequence off the list.

You’re left with 10.

But if you lose, you add another number to the end of the sequence–the amount you just bet. (In this case, $20).

You’re left with 5, 10, 15, 20.

You continue this system until you only have a single number left in the sequence. When that happens, you bet that amount. Win or lose, the sequence is over, and you start a new sequence.

Let’s look at a longer example:

Start with a sequence of 5, 10, 15.

You bet $20, and you lose. You now have a sequence of 5, 10, 15, 20.

Your next bet is $25. You lose again.

Now your sequence looks like this: 5, 10, 15, 20, 25.

This time you bet $30 and win. You cross the 5 and 25 off your list, and you’re left with 10, 15, 20.

Your next bet is $30. You lose.

Now your sequence looks like this: 10, 15, 20, 30.

Your next bet is $40.

This continues until you’ve crossed off all the numbers on the list but one. That’s the amount of your final bet in the progression.

The Labouchere System runs into the same problem as the Martingale, eventually. You’ll sometimes hit a losing streak that’s long enough that you’re placing huge bets. You might not be able to afford those bets. Or you might run into the table limits.

In the short run, sure, the Labouchere System can win you some money. It’s a more fun system than the Martingale if you’re looking for a more robust system to keep track of.

But in the long run, it can’t beat the math behind the game.

3- The Paroli System

The Paroli System resembles the Martingale System.

But instead of doubling your bet after a loss, you double your bet after each win.

Your goal is to win 3 bets in a row, doubling each of them. When you succeed, you start over with a single unit bet.

If you lose a bet, you continue to bet the flat amount.

Here’s an example:

Bet $5 on the first spin. You win. Now you bet $10 on the next spin, and you win again. Finally, bet $20 on the third spin. You win again. Your total winnings are $5 + $10 + $20, or $35.

That’s a 7 unit win.

Here’s another example where you don’t win on the first spin:

You bet $5 on the first spin, and you lose. So now you bet $5 again on the next spin, and you win. Now you raise your bet to $10 and lose. You return to your $5 bet.

Every time you lose, you return to the single-unit bet. You also return to the single-unit bet once you’ve succeeded in winning 3 times in a row.

The ultimate goal is to book a 7 unit win.

The theory behind this system is that winning and losing comes in streaks. When you get hot, you want to take advantage of it.

I think this is a fun way to play roulette, too.

But you should be aware that it doesn’t change the math behind the game. You’ll eventually lose with the Paroli System just because of the math behind the game.

4- The D’Alambert System

The D’Alambert System, like the Martingale System, requires you to raise the size of your bets after losing bets.

Unlike the Martingale System, you don’t have to double your bets, though. The progression is gentler. You might consider the D’Alambert System to be a “lite” version of the Martingale.

Here’s how it works:

You start by placing a single-unit bet. For example, you might decide that a unit is $10.

You bet$10 on black.

If you win, great–the system worked.

If you lose, you increase the size of your next bet by a single unit. In this case, you’d bet $20 on the next spin.

Every time you lose, you increase the size of your next bet a single betting unit. In the example above, if you lost again, you’d bet $30 on the next bet (not $40, as in the Martingale).

There’s one more catch:

Every time you win, you reduce the size of your next bet by a single betting unit. This is a major difference from the Martingale System.

Here’s how that works in the example above:

You bet $10, lost, then bet $20, lost again, and finally bet $30 and won.

Your next bet drops to $20, not $10.

As long as the number of winning bets and losing bets are roughly the same, this is a winning system.

But as you already know, over the long run, you won’t have the same number of winning and losing bets. On an American roulette wheel, over 100 spins, you’ll see about 47 winning spins and about 53 losing spins.

This won’t hold true in the short run–100 spins is still the short run.

But over the course of 1000s of spins, you will get into the long run. And the D’Alambert System will eventually become a net loser.

Still, it’s a fun system, and a little less likely to result in the eventual huge losses you’ll see using the Martingale System.

5- The Fibonacci System

The Fibonacci System is based on the Fibonacci Sequence, or the Fibonacci Series, which is a series of numbers in which the subsequent numbers are calculated by adding the previous numbers together:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89…

The Fibonacci sequence turns up in nature and in math more often than you’d expect. Computer programs use the sequence for search techniques, data structures, and graphs of systems. In nature, the branching of trees, the leaves of plants, and fruit sprouts often follow this sequence.

The Fibonnacci System in roulette uses a little bit of magical thinking. Since this sequence is so popular in nature, it stands to reason that arranging your bets according to that sequence will result in winning more often at roulette. It doesn’t work in the long run, but it can be a fun way to play. It can also win in the short run.

Here’s how the Fibonacci System in roulette works:

Every time you place a bet and lose, you bet the next number in the Fibonacci sequence. When you place a bet and win, you start over.

Here’s an example:

You bet $10, and lose. Your next bet is $10. ($10 plus the previous number, 0.) You lose again, so your next bet is $20. This time if you lose, you bet $30. ($10 plus the previous number of $20.) The next bet in the sequence is $50, and so on.

When you finally win a bet, you cross of the last 2 numbers in the sequence and set your bet at that number. In the above example, say you win the $50 bet. You’d cross the $50 off the list and the $30 off the list. Your next bet would be $20.

Here’s what it looks like, abbreviated:

$10, $10, $20, $30, $50

If you were to continue losing, it would eventually star tot look like this:

$10, $10, $20, $30, $50, $80, $130, $210, $340

Like the Martingale System, the Fibonacci System eventually presents you with a long losing streak and a large bet.

Really, the Fibonacci System isn’t much better or worse than any of the other systems on this list. It’s a little more complicated involved, but not much.

But there’s no magic to the numerical sequence that enables it to beat the house edge in the long run.

6- The Hollandish System

The Hollandish System is another system where you increase your bet size after losing bets.

But instead of re-sizing your bet after each spin, you place 3 bets at each betting increment.

Here’s how the Hollandish System works:

You start by betting $10 on one of the even-money options at the roulette table.

You don’t increase your bets until you’ve won, but once you’ve won, you’ll place 3 bets at the next level of the system. The goal is to recoup any of your previous losses.

You continue to increase your bet sizes until you’re profitable. At that point, you start betting $10 again.

The sequence looks like this:

$10, $30, $50, $70, $90, $110…

In other words, at each level, the bet size increases by 2 units. ($10 is a single unit.)

Here’s an example:

You bet $10 and lose. You bet $10 again, and you lose again. Now you’re down $20.

For your next bet of $10, you win. Now you’re only down $10, and since you just lost, it’s time to increase the size of your bet to $30.

You bet $30 and win. Now you’re up $20, and you can go back to betting a single unit.

But if you lose that $30, you bet $30 again. You don’t increase the size of your bet to $50 until you’ve lost $30 three times in a row.

The progression continues until you’re either in the black or you run out of money.

This isn’t my favorite roulette system. It seems needlessly complicated. I get a little bit of a headache just trying to explain it. I can’t imagine trying to use it.

7- Oscar’s Grind

Finally, I present Oscar’s Grind, which is an easy to understand system. The main thing to remember is that as soon as you’re up a single unit, you go back to the beginning.

Oscar’s Grind has you raising your bet by one unit until you eventually get to 4 units. You don’tt raise your bets when you lose. You just keep moving through the stages.

Using $10 as our unit, the stages would look like this: $10, $20, $30, and $40.

You raise your bets after a win.

So if you place a $10 bet on the first spin and win, you’d place a $20 bet on the next spin. If you win again, you go back to the $10 bet, because you’re now up one unit.

Then you bet $10 and lose. So you bet $10 again, and you lose again. Now you’re down $20, but you win the 3rd. You’re only down $20, and you raise your bet to $20.

If you win the next bet, you’re back to break-even. But since you won, you move on to bet $30.

This is a fun little system that makes the game more interesting. The main downside is that you don’t need a very long losing streak to fall behind.


The best roulette systems are labelled “best” because they’re fun and interesting. Some of them are more effective at winning in the short run than others.

But they all have one thing in common:

They won’t help you win in the long run.

Roulette is a negative expectation bet, no matter what kind of betting system you use. That doesn’t mean you can’t have fun and win in the short run with one of these systems.

My favorite 2 systems on the list are the Martingale and the D’Alambert. Your mileage may vary.
