Strategy Explained for NZ
Since the 18th century, roulette has cemented itself as one of the world’s favourite casino games. The game was first invented in France by a local mathematician, but it wasn’t long before it would spread across Europe, America, and practically every other part of the world. While all casino games are largely based on luck, there are a few (like roulette) that allow you to use intelligent strategies to minimise the house’s edge and increase your chances of landing a big win in online roulette.

None of them will ever guarantee your winning chances, but strategies like the Martingale betting system have been tried and tested by many roulette professionals, and are known to boost your odds in the short-term. If you love playing real money roulette and you’re keen to learn how to use strategy to your advantage, read on to find out more about popular roulette strategies and how they can benefit you.
Using Progressive Betting Strategies
If you play money roulette online, progressive roulette strategy will no doubt become your best friend! Probably the most-well known progressive betting system in roulette is the famed Martingale betting system, which has helped many players to win in the best online roulette games.
Basically, the Martingale system instructs you to double the amount of your bet every time you lose on a spin. Say, for instance, you bet $10 on a spin, and your bet wins. For your next spin, you would bet another $10 according to the Martingale system. However, if you wager $10 and lose that spin, your next spin will need to be $20 instead.
The Reverse Martingale System
There is another progressive strategy that tells you to do the exact opposite of the Martingale system - the Reverse Martingale system. This system tells you to decrease your bets when you lose, and up them when you win. Say that you wager $10 in a spin and you win. For your next spin, you’d up your bet proportionately to $20. However, if you lose a $10 spin, the Reverse Martingale strategy tells you to lower your next spin to $5 to help preserve your bankroll.
Both the Martingale and Reverse Martingale strategies seem to be beneficial when you play real money roulette online. At the end of the day, each of them has merit, so it’s up to you to experiment and find out what suits you best!
The D’Alembert Roulette Strategy
Yet another popular strategy in online roulette games is the D’alembert strategy. This is widely considered to be one of the safest systems you can use, because it relies on small bet increases and decreases. This system is an even-chance strategy, meaning that you can only use it in win or lose bets like Red/Black, Odd/Even, and 1-18/19-36.
All you need to do is pick a wager to start with – like $10 – and increase it by $1 after a losing spin. If you win a spin on a $10 wager, you would instead increase it by $1 to $11 for the next spin. The theory behind this is that, once you’ve lost as many times as you’ve won, you will technically still gain a profit.
Independent Trials in Roulette
If you have read up on roulette strategy, you may have heard the term “independent trials”. This may sound intimidating, but it’s very easy to understand! Independent trials mean that each spin in a game of roulette is independent from the last. In terms of probability, this means that none of your spins have any bearing on the probability of the same outcome occurring again.
For example: if your ball lands on a certain number on the wheel in a spin, your next spin is just as likely to land on that exact number as the last. This is important to understand, as many players have lost good money by thinking that the outcome of a spin means that the same outcome will not happen again!
Placing High Probability Bets
Last but not least are high probability bets. At the roulette tables or when you play roulette online for real money, bets will always be divided into two groups: inside and outside. Inside bets offer a low probability of success but much higher payouts, while outside bets are modest in value but far more likely to occur.
The rule of thumb here is to focus on making outside bets. The reasoning behind this roulette strategy is that these bets offer much better winning odds in the long run. As tempting as the prospect of a big, volatile win is, you should approach inside bets with caution as they can drain your bankroll very rapidly. A payout of 35 to 1 may seem very alluring, but with such slight chances of winning, bets like these can be risky!
