# System 1

The first system is based on betting on changing Dozens and increasing your bet by one betting unit every time you win, until you lose once, then you start your betting scheme all over again with one minimum unit bet on each Dozen. Let's suppose your betting unit consists of $50. You bet $50 on each Dozen different than the one that just came up, totaling your bet to $100 for that sequence. If you win, you increase your total bet on the two Dozens by one unit or $50 by betting $25 more on each Dozen different than the one that just came up. Therefore, your betting sequence will be $100 (the total on the two Dozens with $50 on each Dozen), then $150 ($75 on each Dozen), then $200 ($100 on each Dozen), etc. on every winning bet, until the Dozen repeats and you lose your last bet. Then you start over a new round with $50 on each Dozen.

The round ends when you lose a bet at the end of the sequence. If you win on your first bet, you win 1 unit. If you lose on your first bet you lose 2 units.

If you win on your first bet and lose on your second bet, you lose overall 2 units. If you win the first two bets and lose the third one, you lose overall 1.5 units.

If you win the first three bets and lose the fourth one, you lose half a unit overall.

Now it's going to get more interesting:

- If you win the first four bets and lose the fifth, you win 1 unit overall.
- If you win the first five bets and lose the sixth, you win 3 units overall.
- If you win the first six bets and lose the seventh, you win 5.5 units overall.
- If you win the first seven bets and lose the eighth, you win 8.5 units overall.
- If you win the first eight bets and lose the ninth, you win 12 units overall, etc.

Table 1 below illustrates (in units) what happens in this betting scheme over a round of 30 bets:

*Table 1*

As you can see if you lose up front, your losses are not more than 2 units maximum. When you catch a winning streak (you definitely will), your winnings will escalate to high amounts. Quite a few rounds will conclude within 4-5 bets, where you will lose a couple of units every time. However, when you conclude the round within 11-15 bets, you will be earning 20 to 40 units, making your losses negligible.

Statistically every 100 to 200 spins, you should catch 4-5 winning streaks. Let's take a look at the following simulation of 200 spins in Table 2 and see how that happens. Studying the table will also give you a better understanding of the way the system works.

In the column Change Dozen, the "X" is the winning bet, as the Dozen in column Dozen is different than the previous one, and the numbers are counters until the winning bet occurs.

The column Winning streak counts the number of winning bets until a loss occurs. The loss is designated with a 0.

The column Bet contains the total amount bet on the two Dozens. $100 means that two $50 chips are placed on each two Dozens, the ones that are different than the one that just came up.

The column Cash shows your profit for that bet. Net Profit shows your cumulative profit for all the bets placed so far. If a zero or double zero shows up, that bet is obviously lost. The bet following the zero is based on the number that showed up before the zero. See Sequence 18: the Dozen in Sequence 16 repeats, therefore the bet is lost.

*Table 2*

Now, let's analyze the above simulation in Table 2: you lose your very first bet in Sequence 2 with a loss of 2 units or $100 (our unit is $50). Your next loss occurs in Sequence 5 after having won in Sequences 3 and 4. Losing the third time results in -1.5 units or $75 according to Table 1 reducing your overall net to -$175.

Sequence 6 loses, meaning a two-unit loss of $100, reducing your net to -$275.

Then you catch a relatively small winning streak (Sequences 7 to 12), until you lose in Sequence 13. You have increased your total bet by 1 unit ($50 - or $25 on each two Dozen) every time during this progression. The winning streak counter shows that you have completed the round in the 7th bet. According to Table 1, this means a gain of 5.5 units ($50 X 5.5 = $275) from the net in Sequence 6 (-$275), breaking even.

Then you have some losses with small units (always with small units values) up until Sequence 21, where your net becomes -$500.

Sequences 22 to 29 give you another winning streak of 7 bets until you lose the 8th bet. This gives you +8.5 units (or $50 X 8.5 = $425) according to Table 1, bringing your overall net from -$500 to -$75.

Between Sequences 30 to 76 the results fluctuate up and down a few units, until the moment you have been waiting for in Sequence 77: a winning streak of 10 bets, until it loses at the 11th. A gain of 20.5 units (or $50 X 20.5 = $1025) according to Table 1, increasing your overall net from $100 in Sequence 75 to $1125 in Sequence 86.

You get similar winning streaks in Sequences 141-148 and 150-159. You reach a peak of $3000 in Sequence 164, where it's an excellent time to quit. The remaining sequences maintain your profit level with slight fluctuations, should you decide to quit a bit later. But, it is strongly recommended to quit when you are ahead. You never know when the table will turn against you. Over a long period, it definitely will. With this Roulette System a 200 spin period is a reasonable time to stay as the simulation shows.
