Winning at roulette

I think I've come up with something and need feedback. It's about betting 2 dozens in roulette, doesn't matter which. It goes like this and this is european roulette not the US kind. Every bet is 3 spins and 2 dozens are bet on. For ease i will use $2 as a unit. The first, second and third spin is $2 on each of the 2 dozens. If at the end of the 3 spins you are even then repeat the 3 spins at $2.(but with a caveat, see caveat later) If you are at a loss then multiply that loss by 2.1 and divide by 3 to get the next 3 spin outlays. If you are in profit repeat the 3 spins at $2. Example using 1st and 2nd dozen throughout.
#1 35 loss -$4
#2 24 win -$2
#3 21 win even
Repeat the $2 per spin
#1 18 win +$2
#2 3 win +$4
#3 20 win +$6
Repeat the $2 spin
#1 32 loss -$4
#2 26 loss -$8
#3 28 loss -$12
12 x 2.1 = 25.2. Divide by 3 is 8.4. Next 3 spins are at $8.4 or whatever is rounded.

As far as I've tested if you get 3 of your 2 dozens in a row you will be in profit and you can start again at $2. I have tested to 9 spins of neither of my 2 dozens turning up which means in this case 9 3rd dozens which obviously is highly unlikely but even if it went to 12 which does raise the stakes somewhat, when you do strike 3 in a row you (WHICH YOU WILL) will be in profit. Below is the result
#1 loss -$4
#2 loss -$8
#3 loss -$12

#4 loss -$17 (stake is now $8.5 rounded on each dozen. We don't need to carry forward the $12 loss at #3 as we have accounted for that in the higher stake)
#5 loss -$34
#6 loss -$51

#7 loss -$71 (51 x 2.1 = $107. Divided by 3 is $35.5)
#8 loss -$142
#9 loss -$213
Nine losses in a row. Now we get a 12, 20 and 24 for 3 wins. Stake is now $149. 213 x 2.1 div by 3
#10 win +$149
#11 win +$149
# 12 win +$149

Total stakes on the 12 spins is $1170. Total return is $1341. You can test this on 12 losses and it will still be in profit on the 15th spin if you have 3 winners. Now this is extreme but proves it can work. The caveat is that if you are even at the end of 3 spins you continue with the stake on the last 3 spins. For example in the example above if you were even after #6 you would continue your next 3 spins at $51. ONCE YOU ARE IN PROFIT YOU REVERT BACK TO ORIGINAL STAKE. EG. $2. Comments??

I can see two problems.

First, if one bet wins, and the other two lose, you end up losing half of your base bet (your "base bet" is what you are betting on each dozen). It doesn't look like you are taking those into account. Ignoring situations where you win two and lose the third, breaking even for that set of three, the "win one, lose two" situation occurs 60% of the time.
Probabilities on a single-zero wheel:
Three wins: about 11.5%
Two wins, one loss: about 36.5%
One win, two losses: about 38.5%
Three losses: about 13.5%

Second, which is the fundamental flaw in systems like this, are the three words "WHICH YOU WILL." There is no guarantee of this. True, the probability of a massive number of losses in a row is small, but the amount you end up losing as opposed to what you would win is proportionally larger.

How about an example where you include cases where you win one and lose two? What happens to your money then?

It very much does matter which dozens or columns that you bet on. A column or a dozen has a tendency to sleep sometimes and they can sleep for over 20 spins. That means say, the second doesn't show up for 20 spins or more. If you insist on playing that way never bet the same two columns or dozens twice in a row. That way you're never going to get stuck just betting the first and second dozen when the first dozen goes to sleep for 14 spins. Because you lose twice as much as you win betting this way your losses can add up in a hurry.

Also the best time to play the dozens is in the mornings when they wake up cranky.

They are also prone to afternoon naps.

If a dozens column does fall asleep you can usually wake it up by blasting a horn. Just let the dealer know in advance you are go to be making loud noises to wake up the columns

Darkoz’es air horn idea is very good, but it might get you banned from the casino.

Another tactic you can do is bring some coffee to the table and pour it over (discreetly of course) any columns that fall asleep.

If the coffee doesn’t work then (very discreetly) sprinkle some crystal meth over the sleeping column.

Better yet, dip the chips in the meth and then place the laced chips in the sleeping columns.

They may get high doing this but then you just bet the high numbers ;)

#1 12 win +$2

#3 28 loss -$6

#21 31 loss -$1008

#22 2 win +$706
#23 10 win +$1412
#24 15 win +$2118

I even threw a 3 loss in there. I get total out $6147. Total in $6805. 11% pot.

First of all, I am assuming that whenever you win 1 and lose 2 in a set of 3, you multiply your bet by 2.1 just as if all three lost.

I did some simulating:
If you start out with a bet of 2 on each dozen, and you are allowed to increase your bets 10 times (as I calculate it, after 10 losses, the bet would be 3232 on each dozen, although this probably exceeds most table limits), then:
The probability of reaching the betting limit before a win is 1 in 1663
However, the average loss per session, from when you start until you either win or reach the limit, is 8.8.
Our old friend, "the small wins don't make up for the incredibly large loss."
You don't notice this because, if you ignore the cases where you win 2 and lose 1, you will win 3 about 2/3 of the time, so most of your wins will be really small.

I don't see where you come up with "total in 6805, total out 6147." You lost a total of 1459 in the first 21 spins combined, and made 2118 in the last three.

What you will get in playing this way is a series of losses that you will never recover from. You'll see.

I did make a blue so I did it in a spreadsheet. Above is the correct totals. I do admit that the numbers get big but with this example we only got 9 hits when the odds indicate it should be more like 15 or 16.

This is a really great point. When the second dozen does not hit for 20 spins in a row, the first or third dozen are great bets. At Las Vegas limits, it's worth about $175,000 every time this happens. This is why roulette is such a great game to earn millions on.

Proper psychic preparation is key to the ability to accurately read the dynamic emanations of the roulette wheel horoscope.

Firstly, get sixteen cats. Become deeply immersed in their collective spiritual & olfactory aura, so it becomes an inseparable part of you. Not fifteen. Not seventeen. Sixteen.

Everybody knows this.

That didn't post correctly. Can I insert a pic does anyone know?
