Is it possible to beat the game of roulette using these betting systems? Read on to find out several strategic ways on how to play roulette !

The most successful roulette strategies in a nutshell

Within this guide to the best roulette strategies, we’ll show you the five most common systems, each of which has its own rules to abide by. If you’re a Kiwi that’s still getting to grips with how to play casino games , within this article, you’ll discover how to put the following roulette strategies into practice:

  • Martingale System
  • Reverse Martingale System
  • Fibonacci System
  • D’Alembert System
  • Labouchère System

Martingale – the most famous roulette strategy to beat casinos

The Martingale system is the most popular strategy for roulette betting at any online casino . One of the reasons it has resonated so well with roulette players is the strategy’s simplicity. After every losing spin, you simply double your next wager. The theory is that when you eventually win, you retrieve the money you’ve lost from previous bets and a single unit of profit.

The Martingale system should only be used on Outside Bets with even-money payouts. This covers 1-18/19-36, Even/Odd and Red/Black. That’s because Martingale is ideal for use when the probability of winning is as close to 50% as possible. In European Roulette, the odds of winning an Outside Bet is 48.65%. It’s just 47.37% in American Roulette, which means European Roulette is a better option for this system.

The theory is that these even-money wagers are less likely to result in brutal losing streaks as they are effectively coinflip scenarios every spin. However, there is nothing to say brutal losing streaks cannot happen, which is the significant risk of Martingale, eating into your bank with every losing bet.

In fact, after eight losing spins in succession – starting from $1 – you would have to wager $256 for the ninth spin. Before this, you would have already lost $255, so you’d need a bank of $511 to absorb eight consecutive losses.

Note: Some roulette games will also have maximum bet limits that could prevent you from betting big enough to reclaim your previous losses.

And what is a Reverse Martingale roulette strategy?

The Reverse Martingale strategy also proves popular among Kiwi roulette players. It’s another ‘progressive’ betting system. But you double your stake after every win instead of doubling it after every loss. This effectively gives you a ‘free hit’ at maximising your bankroll with back-to-back winning spins. That’s because by doubling your stake after a win, you’re effectively betting with the money paid out from the previous win.

Fibonacci – does the golden rule apply to casino games?

Another popular roulette strategy is inspired by the now-iconic number sequence coined by Fibonacci. It’s considered a safer betting strategy than Martingale for casino games with even-money payouts like roulette.

That’s because the increase of the bet stake is aligned to the Fibonacci sequence that doesn’t increase anywhere near as steeply as the Martingale strategy. Like Martingale, the Fibonacci system is best suited to even-money Outside Bets.

The Fibonacci sequence looks like this:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987

If you win your first bet with one unit, you’ll restart the sequence again from one unit. If you lose, you’ll advance to the next number in the sequence. If you’ve advanced halfway through the sequence by the time you land a winner, move back two numbers in the sequence and start betting with that amount.


If you want a roulette strategy less aggressive than the Martingale and Fibonacci systems, you may wish to consider the D’Alembert strategy. This is known as a ‘flat progression’ system.

Rather than the doubling down of stakes after losing bets, flat progression systems aim to keep the size of wagers more in line with the pattern of play. In D’Alembert, you gradually increase the size of your bet by one unit after losing spins and gradually reduce it by one unit following a winning spin. The thinking is that this type of system takes losing runs into account and the likelihood that long winning runs are by no means a certainty.


The Labouchère system operates in a similar vein to the D’Alembert strategy. It’s also designed to work best with even-money bets. How sequence of bets ultimately depends on your target amount to win from a roulette session.

Let’s say you wanted to win NZ$20. You would create a bet sequence that adds up to 20:


You must then place your first wager using the furthest left and furthest right numbers. In which case, this would add up to $2. If the bet wins, you’ll cross these numbers off the sequence, so it would then look like:


Your next wager would then be 1+2 = $3. If your bet loses, add the furthest right number in the sequence to the stake you just placed e.g. $3 + 2 = $5, but do not cross any numbers off.

Why roulette strategies like these don’t work

The reality is that although these roulette strategies may help to provide some organisation to your betting, they cannot work long term. That’s because table games like roulette have an inherent house edge – also known as a casino RTP . This means that they are programmed to take a small cut out of your wagers over the long term.

Betting strategies like Martingale are best suited to games with a 50% probability. At 48.65%, European Roulette is close to that, but it still means you’ll statistically lose money over the hundreds or thousands of spins.

Are there some ways I can at least improve my odds in roulette?

Avoid double-zero roulette tables. They carry the poorest house edge (5.26%). Playing single-zero roulette games can almost cut the house edge in half from 5.26% to 2.70%. Both the European Roulette variant and French Roulette will have a higher RTP than the American ones.
