Roulette Strategy Guide

How Roulette Strategies Work

Most roulette strategies fall into one of two categories: progression systems and coverage systems.

Progression systems adjust your bet size based on whether you won or lost the previous spin. They come in two flavours. Negative progressions (like Martingale) increase your bet after a loss, trying to recover what you’ve lost. Positive progressions (like Paroli) increase after a win, trying to capitalise on hot streaks. Both eventually reset back to your starting bet.

Coverage systems don’t change your bet size at all. Instead, they spread bets across the table to cover more numbers per spin. The James Bond strategy is the classic example. You hit more often, but each win pays less.

Neither type changes the expected value of the game. What they do change is the distribution of outcomes. Some strategies are basically trading a few big losses for many small wins. Others do the opposite. Understanding this tradeoff is really what roulette strategy is about.

The Martingale Strategy

The Martingale is the most famous roulette strategy for a reason: it’s dead simple. You pick an even-money bet (red, black, odd, even, high, or low), start with a base bet, and double it every time you lose. When you eventually win, you recover everything plus one unit of profit. Then you go back to the base bet and start again.

Here’s what a typical Martingale sequence looks like on red/black:

Looks great on paper, right? The catch is what happens when you hit a longer losing streak. After 7 consecutive losses starting from a 10 unit bet, you’d need to wager 1,280 on the next spin just to win back 10. Most players either run out of bankroll or hit the table maximum before they can recover. It’s rare, but it happens, and when it does it wipes out dozens of previous small wins.

Best for: Players who want frequent small wins and don’t mind the occasional big loss. Works best with a large bankroll relative to your base bet and a table with a high maximum.

Reverse Martingale (Paroli)

The Paroli flips the Martingale on its head. Instead of doubling after losses, you double after wins. The idea is to ride winning streaks while keeping your losses small during cold spells.

Most players set a cap of three consecutive doubles. So you bet 10, win, bet 20, win, bet 40, win, then pocket the profit and reset to 10. If you lose at any point, you go straight back to the base bet. Your maximum risk on any single sequence is just one base bet, which makes the Paroli much less stressful than the Martingale.

Best for: Players who want to protect their bankroll while still having a shot at solid short-term gains. The risk is genuinely more contained than negative progression systems.

The D’Alembert Strategy

Named after the 18th-century French mathematician Jean le Rond d’Alembert, this one is often recommended for beginners because it’s gentle. After a loss, you increase your bet by one unit. After a win, you decrease it by one unit. That’s the whole system.

The theory behind it is called the "equilibrium of nature" — the idea that over time, wins and losses should roughly balance out. If you win and lose the same number of times, you end up in profit because your winning bets were (on average) slightly larger than your losing ones.

The progression is much slower than Martingale, which means your bankroll lasts longer. The flip side is that recovering from a deep losing run takes more wins. You won’t see the dramatic swings of a Martingale player, but you also won’t see the dramatic recoveries.

Best for: Conservative players who want to extend their playing time and prefer steady, predictable sessions over big swings.

The Fibonacci Strategy

You might remember the Fibonacci sequence from maths class: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55... Each number is the sum of the two before it (1+1=2, 1+2=3, 2+3=5, and so on). In roulette, you use these numbers as your bet multiplier.

Start at the beginning of the sequence. After a loss, move one step forward. After a win, move two steps back. The goal is to get back to the start of the sequence, at which point you’ll be in profit.

The Fibonacci escalates more slowly than the Martingale because each step isn’t a full doubling. After 7 losses, a Martingale player is betting 128 units. A Fibonacci player is betting just 21. That’s a meaningful difference when your bankroll is under pressure.

Best for: Players who like the idea of a progression system but find Martingale too aggressive. A good middle ground between D’Alembert and Martingale.

The Labouchere Strategy

Also called the "cancellation system," the Labouchere gives you more control over your target profit than other strategies. You start by writing down a sequence of numbers. Something like 1-2-3-4-5. The sum of all numbers (15 in this case) is your target profit.

Before you write the sequence, set a budget for the session. The total of all the numbers should equal the profit you want to walk away with, and the individual values should be sized so that no single bet would burn through your bankroll.

Each bet equals the first number plus the last number in your sequence. So your first bet would be 1 + 5 = 6 units. If you win, cross off both the first and last numbers (leaving 2-3-4). If you lose, add the amount you just lost to the end of the sequence (making it 1-2-3-4-5-6).

When you’ve crossed off all the numbers, you’ve hit your target profit. The beauty of this system is that you pick your own sequence, which lets you control how aggressively the bets escalate. A flat sequence like 3-3-3-3-3 is far less volatile than 1-2-3-4-5.

Here’s a compact example using the starting sequence 1-1-3-4-1 (target profit: 10 units):

Best for: More experienced players who want to set a specific profit target and enjoy the planning element. Requires pen and paper (or a good memory).

The James Bond Strategy

Supposedly Ian Fleming’s favourite way to play, the James Bond strategy covers over two-thirds of the table with every spin. Using a total stake of 200 units, you split it like this:

• 140 units on high numbers (19-36)
• 50 units on the six-line covering 13-18
• 10 units on zero as insurance

This covers 25 out of 37 numbers. If 19-36 hits, you profit 80 units. If 13-18 hits, you profit 100 units. If zero hits, you profit 160 units. You only lose when 1-12 comes up, which costs you the full 200.

Best for: Players who like hitting frequently and want a structured, fixed-bet system. The risk comes from the roughly one-in-three chance of hitting 1-12 and losing everything.

Which Strategy Should You Use?

There’s no single "best" roulette strategy. The right choice depends entirely on how you like to play:

• Want frequent wins? Go with Martingale or James Bond. You’ll win more often but the losses, when they come, will be larger.
• Want to protect your bankroll? D’Alembert or Paroli. Slower progression means longer sessions and less risk of a catastrophic loss.
• Want a balance? Fibonacci gives you moderate escalation without the extremes of Martingale.
• Want full control? Labouchere lets you set your own target and pace. It’s the most customisable system.

The honest advice? Try a few on the simulator and see which one feels right. Strategy is as much about your comfort level as it is about the maths.

Bankroll Management: More Important Than Any Strategy

Whatever system you pick, how you manage your coins matters more than the system itself. Every experienced roulette player will tell you the same thing: the biggest mistake isn’t choosing the wrong strategy, it’s not knowing when to stop.

Common Mistakes to Avoid

Even players who know the strategies well sometimes fall into these traps:

• The Gambler’s Fallacy. Believing that because red has hit 8 times in a row, black is "due." Every spin is independent. The wheel doesn’t have a memory. Red hitting 8 times doesn’t make black any more likely on spin 9.
• Betting more than you planned. Strategies give structure, but they only work if you actually follow them. The moment you deviate because of a gut feeling, you’re just gambling without a plan.
• Playing American roulette when European is available. That extra zero nearly doubles the house advantage. There’s no strategic reason to choose American over European.
• Ignoring table limits. If you’re using a progression system, make sure the table maximum gives you enough room for your sequence. A Martingale on a table that caps at 500 with a base bet of 10 only gives you 6 doublings before you hit the ceiling.
