As with all progressive systems you must be very careful when you use them, the d’Alembert is not as dangerous as the Martingale but it can still be the cause of very large losses.
Up and Down
Like the D'Alambert, only reversed. Every time you win, increase your bet by your initial amount. Every time you lose, lower it by the same amount.
Place your bets according to the following sequence: 5-5-7-7-10-10-15-15-25-25-35-35-50. Once you reach the top
of the sequence, continue to bet 50. If you should happen to lose at any point, restart the sequence. (quit and revert any time you are even or when ahead by a comfortable margin - personal choice)
2 in 5
Place your bets according to the following sequence: 5-7-12-15-25. As soon as you win two bets in the series, or if you should happen to lose at 25, restart the series.
Place your bets using the following sequence: 1-1-1-4-8-16. Progress to the next number in the series if you lose. If you should win, however, double (parlay) this amount and bet again. If you should win again, restart the series. If you should lose, move up to the next number in the progression. Once you lose at 16, start the sequence over.
Similar to the D'alembert, except instead of doubling or halving your bet each time, move up and down based on the following sequence: 1-1-2-3-5-8-13-21-34-55-89-144-... Like the D'alembert, should you lose, move to the next number in the series. Should win you, fall back one number (or stay at that number then revert to base bet).
EXAMPLE: a progression of 4 losses and two wins (LLLLWW) leaves us at -1 -1 -2 -3 +5 +3 = +1, where we have lost twice as many bets as we have won, but still pocketed 1 unit, simply because we have won two bets in a row.
In a similar series where we do not win two in a row, but only 2 of 3 (LLLLWLW) we again restart the series, but this time out profit picture will be -1 -1 -2 -3 +5 -3 +5 = 0, where our 2 of 3 wins has neutralized the progression, and we start again at 1 unit.
And suppose we decided to play a 12-step Fibonacci, with our top bet being 144 units. Our total risk, which is the complete
and utter loss of an entire series, is 376 units, or 1 +1 +2 +3 +5 +8 +13 +21 +34 +55 +89 +144 = 376. We can lose
eleven bets in a row, (LLLLLLLLLLLWLW), lose a total of 232 units in a row, then win 144, lose 89, win 144 for a total loss of 33 units, less than 10% of our session money.
The odds against losing 11 bets in a row are the same as winning 11 bets in a row, 2047 to 1. And the odds against losing our whole series of 12 bets are 4095 to 1. You could use this system 365 days a year and expect 11 losses in a row every 5 ½ years, and a loss of a total series once every 11 years The problem with the Fibonacci is not safety, therefore, but the fact that approximately half of your wins will come at the very first level of 1 unit, making it a boring albeit profitable grind. In order to counteract this situation, some gamblers will begin their progression at the 4th or 5th level, and alternately move up or down as they win or lose, depending on their temperament and goals.
EXAMPLE: We begin with 5 units and win. We then move up the progression and win 8 units. We have won a total of 13 units and completed our Fibonacci objective of two wins in a row. Now we reduce our bet to 3 units, locking in a profit of 10 units if we lose it. But if we win that 3 units bet, our next is 5 units. The variations are practically limitless, and the safety level is very high. The Fibonacci is a great system for the recreational gambler, the grind player who wants a few enjoyable hours gambling without jeopardizing his mortgage, and the pro who wants to ease into his game before he gets serious.
To use the Fibonacci properly, a player must first memorize the progression, and then practice at home flipping a coin, until
the bets are made automatically. It is a perfect system for all the even-chance games like Craps, Baccarat and Roulette, and can be easily modified into a money-management system for Blackjack and sports betting. It is also acknowledged as an excellent system for partners betting opposite each other. However you decide to employ this versatile progression, you will find fewer more powerful ways to win with as little risk.
