Regressive strategies, as you might have guessed, involve doing the opposite: If you suffer a loss then you make a lesser bet the next time around, hoping to avoid excessive losses after a losing streak. Strategies you can use include the polar opposite of those already mentioned – the Reverse D'Alembert and Anti-Martingale.
These, though, are very basic ideas – it gets much more refined:
The
LaBouchere system is also used mainly for even bets and uses a line of custom-designed numbers, increasing in value that add up to the total amount you aim to win in any one session.
To get started, you'll need to devise a line of numbers, increasing in value that add up to the amount you aspire to win in any one session.
These numbers determine how much you need to bet (they have nothing to do with the numbers on the Roulette wheel). The amount you bet is the sum of the very first and last numbers. You cross these both off if you win, and insert their combined total at the end of the sequence if you lose.
The
Fibonacci System falls somewhere between other well-known systems. It uses the famous mathematical progression we all vaguely remember from school but which never seemed to serve any purpose – but you'll be pleased to hear there is a use for it. The sequence adds two consecutive numbers to make the next number in the sequence as follows:
1,1,2,3,5,8,13,21,34,55,89,144 etc
When you suffer a losing bet, you simply bet multiples based on the figures shown in turn. Once you're winning there's no need to worry about the sequence.
