This betting method is also called Tiers Et Tout A La Boule De Neige or short just Tiers Et Tout (tier et tout, French: a part and the whole). It is named after the legendary Spanish gambler Thomas Garcia who was a cardsharper and used marked cards and loaded dice to get consistent wins. By August 1860 he accumulated a sizable gambling bankroll and went to Homburg for the first time to try this progression with bets on Red and he was betting big. Sometimes he lost heavily, but he managed to break the Bank 5 times during his first two visits. He came back for the third time one year later in the autumn of 1861. This time he lost all of his bankroll plus the money he could borrow from others during his stay. The Garcia Progression is a mainly positive progression increasing the bet amounts by the money won. But you will notice that it actually is a mixed progression including a two step negative Martingale progression.
You take a certain amount, from which you use 1/3 for the first bet. If this first bet is lost, you bet the rest, therefore 2/3 of the available amount. If you win the first or the second bet, you increase the original amount by the profit gain and bet again; first 1/3 of the increased amount and if the first bet loses, you bet the rest of 2/3 of your bank. Example of Tiers et Tout:
You start with 9 units using 3 units for the first bet and when this bet loses, you bet the remaining 6 units. If one of the 2 bets wins, you have now 9 + 3 units available.
Now you bet 4 units and if this bet loses you bet 8 units. A win on either bet leads to 12 + 4 = 16 units.
Now you bet 5 units and in case of a loss 10 units. If one bet wins your bankroll is16 + 5 = 21 units.
The next bet is 7, if the first bet is lost 14 units. A win brings the balance to 21 + 7 = 28 units.
The next bet is 9, resp. 18 units, bringing the capital to 28 + 9 = 37 units.
Now you can bet 12 units and in case of a loss, you bet 24 units. New bank is now 37 + 12 = 49 units.
Next stage 15 / 30, balance: 49 + 15 = 64 units.
Next stage 20 / 40, balance: 64 + 20 = 84 units.
Next stage 25 / 50, balance: 84 + 25 = 109 units.
After stage 6, you take 4 units and after stage 7 you take another 5 units from the bankroll. Now you operate with your winnings only. From stage 9 onwards you stay with the bet amounts of 25 / 50 until you have 2 consecutive losses. For demonstration purpose the following example bets on the last spin result of the High / Low chance. A variation could be to split the bankroll in a way that enables you to bet three or even four times in order to outlast two and three consecutive losses. Winning streaks, even with intermediate consecutive losses of two bets can continue in the most favorable case over more than 70 bets, whereby it is possible to reach the table maximum. An example would be to split a 100 unit bankroll into 16 units, 28 units and 56 units. The profit could be 16 units, 12 units or 12 units depending on whether you win the first, second or third bet.
|10||22||X||12||+12||+31/+27||Take 4 units from balance|
|12||15||X||30||+30||+42/+37||Take 5 units from balance|
This is a nice example of a short session playing the Garcia Progression. Eight lost bets and 13 won bets bring your balance up to +107 units ending the session with spin No 22 after two consecutive losses. The lowest balance was just -10 units.
Obviously this form of progression is quite interesting because the gains can come very fast as long as you do not encounter 2 consecutive losses. You can use the Garcia Progression with any betting selection on the even money chances. The strength and attractiveness of that progression is that you won't lose more than 9 units per attack, but if you are lucky you can win a significant amount of money. A disadvantage to the progression is that it may take several attacks until you find a nice winning streak and it may become quite frustrating to lose everything after reaching a higher stage in the progression.
For demonstration purpose we have tested a simple roulette system. The rules are just to bet on the Low chance using the Oscar's Grind strategy. The first test run shows the results for the progression if there was no zero on the roulette wheel for the purpose of demonstration how it work for real 50:50 chance games. Hence you know what to expect if you use the strategy e.g for bets on Player at Baccarat. The almost equal distribution of High/Low results with 16043/15957 produces a profit of 4789 units seeing a maximum drowdown to -2509 units. The highest bet amount is 495 units. The results for single zero roulette wheels are shown in the other two tests. As you can see in the charts most of the time the bet amounts stay relatively moderate but at times they increase up to a maximum of 1087 units in the RNG and 9459 units in the Live Dealer test run. The longest observed losing streaks are 13 spins long in both tests. Due to zero the RNG test showed 15836 won and 16164 lost bets. The live wheel showed 15508 won and 16492 lost bets. If there are not enough or too short streaks the Oscar's Grind progression may dive so deep into the negative terain that it becomes impossible to recover. The different results of the RNG and the Live Dealer test demonstrates that fact.
