The Guetting Progression


How the Guetting Progression works

The Guetting Progression was developed by the French gambler Charles Guetting, who won a fortune during his many years in Monte Carlo. He used this progression for his game at Trente-et-Quarante, a game distantly related to Baccarat. However his progression can be applied to any even money bet and so at roulette.

The Guetting Progression is a four levels positive progression. You may find descriptions where the levels are called gears or stages, which does not change anything. But some websites wrongfully describe the way of using the progression, so watch out where you get your information from.

The Levels of the Guetting Progression

1. Level: 1
2. Level: 1,5 / 2 / 3
3. Level: 4 / 6 / 8
4. Level: 10 / 15 / 20

If your table chips don't enable 1,5 units for your game just double the figure to get integers.

1. Level: 2
2. Level: 3 / 4 / 6
3. Level: 8 / 12 / 16
4. Level: 20 / 30 / 40

Each and every bet amount has to win twice in a row to permit a move to the next higher bet amount. After two consecutive won bets of one bet amount the progression moves on to the next higher bet in that level or to the first bet at the next higher level. So if you are on a winning streak of 20 consecutive wins you win 141 units and your bet series looks like:

1 / 1 / 1,5 / 1,5 / 2 / 2 / 3 / 3 / 4 / 4 / 6 / 6 / 8 / 8 / 10 / 10 / 15 / 15 / 20 / 20

The Rules of the Guetting Progression

After a lost new bet, the Guetting Progression steps down to the first bet size at the next lower level, therefore down to 4, 1.5 or 1, depending on, at which level the bet was lost. So you always have to drop a level if immediately after two consecutive won bets the next higher bet is lost or if 2 consecutive losses appear. Whereas if the lost bet is the second bet of the same bet amount you have to bet the same amount again.

The following guide should make the procedure clear. Follow the blue arrows after a win and follow the red arrows after a loss.

Below you can find a game example to get an idea how it is played. For demonstration purpose we bet on the last High / Low chance that has appeared.

731X1+102nd bet won. Step up a level.
928X1,5+1,5+32nd bet won. Step up a bet.
119X2-2+32nd bet lost. Bet same.
1323X2-2+32nd bet lost. Bet same.
1531X2+2+72nd bet won. Step up a bet.
1726X3+3+132nd bet won. Step up a level.
1810X4-4+91st bet lost. Step down a level.
1925X1,5-1,5+7,51st bet lost. Step down a level.

This is a nice example of how the progression makes its way up through the levels on extended streaks. The strategy's attempt is to lose low during losing streaks and to gain a substantial win by betting higher and higher during the winning streaks. The progression unfolds its full strength during phases of long winning and losing streaks. At the end of the session when the results get choppy the bet amounts drop quickly down in order to lock in some of the gained profits. Ending the session with spin No 22 leaves you a net profit of +6,5 units.

Advantages and Disadvantages to the Guetting Progression

The strength of the Guetting Progression is to take advantage of winning streaks and to keep the bets low during choppy and losing streaks. What realy hurts this betting strategy are series of two wins followed by a loss like WWLWWLWWL.

RNG and Live Dealer Tests of the Guetting Progression for 32000 bets

For demonstration purpose we have tested a simple roulette system. The rules are just to bet on the previous appearance of the High and Low chance using the Guetting strategy. The first test run shows the results of the progression on a No Zero RNG roulette wheel to demonstrate how it work for real 50:50 chance games. The almost equal distribution of Won/Lost bets with 16017/15983 produces a profit of 26,5 units seeing a maximum drowdown to -82,5 units. The highest bet amount is 15 units. The progression never reached its highest possible bet amount of 20 units.

The results for single zero roulette wheels are shown in the other two tests. As you can see in the charts the presents of zero at roulette takes away any possibility of making profits over a larger number of bets. The longest observed losing streaks are 13 spins long and 15 spins long in the RNG and Live Dealer tests respectively. Due to zero the RNG test showed 15515 won and 16495 lost bets. The live wheel showed 15585 won and 16415 lost bets.
