There are three different categories of betting systems:
An explanation of the most commonly used betting systems follows. Although many will find this information useful, it is important to bear in mind that none of the techniques described below are perfectly reliable. One of the reasons for that is that all betting systems are constrained by mathematics and probabilities, meaning that there is no sure-fire technique that should be used at all times.
The Gambling Fallacy technique wrongly assumes that because a certain card or number has not shown up recently, it will definitely occur in a near future, hence the self-explanatory name of this particular betting system. The problem with this technique is that it incorrectly takes for granted that mathematical probabilities will give reason to whoever attempts to predict a 'future' situation. This is why relying on the Gambling Fallacy is highly risky, simply because the factual grounds of such a technique are largely inaccurate. Though it might be tempting on certain occasions to rely on the likelihood of an event to occur by basing one's judgment on past events, it would be advisable to avoid using this technique.
Often labeled as a proof-tested system due to its old origins, the Martingale system takes for granted the fact that you will lose an infinite amount of times in a session, and applies largely to 'even money' bets. The principles of the system are as follows: if you win, you should alter your bet, but if you lose, you should aim at doubling the bet you just lost. The Martingale system is therefore a negative progression system. As described above, it is consequently a highly risky technique that relies on a considerable bankroll. The main idea behind the system is that despite the fact that you will lose on a regular basis, there is a moment when you will win, allowing you to recover all of your losses plus an extra. However, a number of casinos have house limits, which means that if you should reach that limit, the technique loses its credibility and legitimacy.
Similar in principle to the Martingale system but much safer, anyone using the D`Alembert system will raise his bet after each time he loses, and similarly will decrease his bet every time he wins. Using this technique will allow you to compensate your losses by gradually betting higher after losing, whilst letting you keep most of your winnings by betting slightly less each time you win.
Commonly used in horse racing, the Parlay system aims at taking the winnings from one bet, and investing those on the following bet. Being a positive progression system, this system can be regarded as being reasonably safe. Players using this technique generally aim for a winning situation that will occur in a quite distant future, as in theory it should protect the accumulated winnings.
The Paroli system is exactly the opposite of the Martingale system: if you win, you increase your bet. As opposed to the Martingale system, the Paroli system substantially enhances your winning if you are enjoying a winning streak situation. Most importantly, this system does not involve an important bankroll.
The 1-3-2-6 system is a positive progression system that takes for granted that you should be able to win four times in a row. If bets are categorized on a scale of one to six units(six being the highest bet), your first bet should be 1 unit, the second 3 units, the third 2 units, and the fourth 6 units. Despite the mathematics involved in this system, it is fairly straightforward. All in all, the system offers insurance by altering the bets each time, and taking money away when you win at particular moments. If you end up winning four times in a succession, it is a very good opportunity to substantially increase your bankroll. However mathematics have the final word: it is equally as likely that you will lose four times in a row.
