Title: Double Dozen Parlay
Post by: GLC on Sep 24, 05:08 PM 2011
It's been way too long since I posted a really fun system that leaves the roulette dealers scratching their heads wondering what hit them as you head up to the cashier window with a bucket of chips.


I've actually been having a lot of luck playing my flat bet parlay bet progression on even chances, so I thought I would see how it worked on a double dozen bet.  After all, we have a really good chance to hit 4 in a row betting 2 dozens or columns.


Just so you'll keep reading, it works GREAT!! :xd:


I play it betting either the last 2 dozens to hit or the last dozen and the farthest back dozen to hit.


So, If I get 1-3-2-2-3-1  playing last 2 dozens, I would bet on 1st and 3rd dozens.
If I get 1-3-2-2-3-1  playing last and farthest, I would bet on the 1st and 2nd dozens.


You can, of course, use any double dozen bet selection method that you like.


This is a parlay system.  If I win, I divide all the units on the table in half and bet my dozens again.


Example:  using 2-2.  I bet 2-2 on my dozens.  If I win I have 6 units on the table.  My original 4 plus the 2 units I just won.  My next bet will be 6 / 2 = 3, so 3 units on each dozen.  If I win this bet, I will have 9 units on the table.  I take 1 back leaving 8 / 2 = 4, so bet 4 units on each dozen.  If I win this bet I will have 12 units on the table and I make my last parlay.  12 / 2 = 6 on each dozen.  If I win, I will be up 14 units.  18 minus my original 4 units leaves me with +14 units.


My progression is:


Level      If lose       Bets                                         If Win
1)             -2            1-1                                           +1
2)             -5*          1-1; 2-2                                    +1
3)             -8            1-1; 2-2; 3-3                             +1
4)             -11          1-1; 2-2; 3-3; 3-3                     +1
5)             -15          2-2; 3-3; 3-3; 4-4                     +1
6)             -19          2-2; 3-3; 4-4; 6-6                       0
7)             -23          2-2; 3-3; 4-4; 6-6                      -4
8 )             -29          3-3; 4-4; 6-6; 9-9                      -1
9)             -35          3-3; 4-4; 6-6; 9-9                      -7
10)           -41          3-3; 4-4; 6-6; 9-9                      -13
11)           -49          4-4; 6-6; 9-9; 13-13                  -9
12)           -57          4-4; 6-6; 9-9; 13-13                  -17
13)           -65          4-4; 6-6; 9-9; 13-13                  -25
14)           -77          6-6; 9-9; 13-13; 19-19              -18
15)           -89          6-6; 9-9; 13-13; 19-19              -30
16)           -101        6-6; 9-9; 13-13; 19-19              -42
17)           -117        8-8; 12-12; 18-18; 27-27          -36
18)           -133        8-8; 12-12; 18-18; 27-27          -52
19)           -149        8-8; 12-12; 18-18; 27-27          -68
20)           -169        10-10; 15-15; 22-22; 33-33      -69
21)           -189        10-10; 15-15; 22-22; 33-33      -89
22)           -209        10-10; 15-15; 22-22; 33-33      -109

* The reason level 2,3 and 5 increase by 3 instead of 2 is because when we bet 1-1 and win, we only have 3 units so we have to add another unit making it 4 / 2 = 2 on each dozen.  Thus when we lose, we will also lose the 3rd unit we contributed.

We're playing this progression until we win all 4 bets on a level or reach a new high bank.


When we win 4 bets on a level, we drop back to the level that if we win we will be fully recovered.  We can determine that by subtracting the units we've just won from the units we were down and we find the appropriate level our new units down falls in and we drop back to that level.  If we win at that level, we will be fully recovered.


You'll notice in the beginning, we don't have to win 4 in a row to reach a new high.  You have the option of playing the way I have presented it in my chart or you can always play for 4 in a row wins on every level, even the 1st level.  It's a little riskier, but the rewards may be worth it.


One last comment.  If you want to play it flat betting, I would suggest that you flat bet at the 2-2 level instead of the 1-1 level.  Refer to my * note for the explanation.


Enjoy,

Just in case you like a martingale type progression:


This is based on only winning 3 times in a row.  Very easy to do on double dozens.


1-1
1-1
2-2
3-3
4-4
6-6
8-8
12-12
18-18
24-24
36-36


If you lose all levels, you will lose 232 units.


This, like all systems, can lose.  Expect it to and don't be disappointed when you have to give back a chunk of your winnings every now and then.

To be honest my friend I don't think one method is necessarily better than another.  I have tried bet the last 2 dozens to hit.  bet the last and farthest dozens to hit.  Bet the 2 farthest dozens to hit.  I have also played R E latest phenomenon.  I think it's a little better than the other 3 methods.  I wait until a dozen has hit 2 or 3 times in the last 3 spins and I bet the 2 other dozens.  This isn't as fast paced, but it does seem to catch 3 in a row a little more steadily.


Granted, I've only tried each of the 4 bet selection methods 2 times each to +50 units.  Hardly enough bets to be making generalizations about which is the better method.


I've never had to bet beyond the 12-12 level with any of them.  That day's coming, believe me.

Oh I believe U George.

I had a few days like that lately!  :'(

Have recovered some now tho.

I have been looking into "Alternative" bets, and arrangements.

Here's a few "Jewels" I have been examining, one of which gives the same cover, as two dozens.


The 4 Lines bet, covers exactly 24 numbers on the table/wheel (66.666%)
Same as 2 x Dozens.

I just played to +50 two more times using R E's idea with a little twist on it for double dozens.


I wait until a dozen has hit 2 or 3 times in the last 3 spins and then I bet on the other 2 dozens. 


If all 3 dozens hit in the last 3 spins, in other words no repeats, I don't bet.


I know, I could play 4 or the 6 lines and I could play 8 of the 12 streets.  I have a feeling it would give me a little more control over zeroing in on the lines or streets that are due.  (Oh no.  Sounds like full blown gambler's fallacy).


I've change the progression by eliminating the 2nd 1-1 and going straight to the 2-2.  That way if I lose at 1-1 and win at 2-2, it's a break even point and I can start over with 1-1.


I know, the most obvious way to lose the progression is to have the same dozen hit 10 times in a row.  An rare event but one that can certainly happen.  I'm considering switching to last 2 dozens to hit if I get a dozen to hit 4 times in a row.


Betting dozens isn't as strong as betting lines or streets, but it takes a smaller bankroll.


I will look into the other options! ;) :thumbsup:

Title: Re: Double Dozen Parlay
Post by: GLC on Sep 25, 12:32 AM 2011
If you have 500 units to invest, I think this is worth looking at.


We track until we have a dozen that has hit 2 or 3 times in the last 3 spins.  Then we bet on the other 2 dozens.  If we have a dozen that hits 4 times in a row, we switch our bet to that dozen and the other most recent hit dozen.  We continue to bet on these same 2 dozens until we lose.  If we have no repeats in the last 3 spins, no bet.  If a zero hits, just take the loss and act like the zero never showed.


Those are the bet selection rules.


We will use a 2 step parlay.  That means we make our bet and if it wins, we divide the chips between the next 2 dozens our selection process says to bet on.  If we win 2 in a row, we will be at a new high and can start over with 1-1.


We play our progression until we are even or +1 or more and then we start over at 1-1.


Our progression is:
1-1
2-2
3-3; 4-4
6-6; 7-7
10-10; 15-15
18-18; 27-27
33-33; 49-49
60-60; 90-90
110-110; 165-165


If we lose all 9 attempts, we will be down 486 units.


This is acting like the strongest march I've tested so far.  I'm up 600 units so far.  Granted  400 were earned playing the above 3 step parlay, but I would have won quicker on every session had I been playing this 2 in a row method.

Hello

This is the type of a system that will work for you if u are patient enough, have a sufficient BR and nerves of steel. ;D

Prepare for some big drawdowns too.

Thanks for posting

Another alternative could be playing on the last 24 numbers that hit. Getting long sequences of winners is also easy that way.

Actually, I think it woud be interesting to test with real spins betting on the last 24 against 24 picked randomly and against the 24 sleepers, see what comes out after 100,000 spins.

I have a couple observations.  The achilles heel is a long series of repeats by a single dozen.  We could incorporate a new rule.  Instead of waiting for a dozen to show 4 times in a row and then betting for the last 2 dozens to show hoping to catch that repeating dozen continuing to repeat, we could just stop betting when we have a single dozen showing in the last 3 spins.  That would give us a "no bet" situation when we have all 3 dozens showing in the last 3 spins and also only 1 dozen showing in the last 3 spins.  Meaning that we only bet when we have 1 dozen showing twice and another dozen showing once.


I have also been thinking about using  LLL's and WWW's for triggers.  Something like stop betting after an L until the next W and continue to bet until the next L.  Said another way, never bet after a Loss and always bet after a Win.


Observations regarding 2 in a row progression vs 3 or 4 or 5 in a row progressions.  I notice that if we build our progression based on a full recovery with a win at any level, the more times we have to win in a row, we don't get that many more levels in the progression.  That's why I went to 2 in a row.  I think it gives us a better ratio on wins in a row vs levels in progression.


One last thought.  The progression I posted in the initial post does not recover fully after any win.  This type progression can give us more opportunity for a full recovery eventually.  But it may also just be a slower death because it too will eventually lose.  The pure martingale type progression wins a lot quickly, but we are limited by a relatively small number of losses in a row before losing our progression.  With a multiple win for full recovery progression we can have an almost unlimited number of levels, but this curtails units won per spin in direct proportion to the reduction in risk of a total progression loss.


I know the above is obvious to some of us but I wanted to post it so we can start testing different scenarios.  In the end, we will each have to decide which way suits our style.


I think Jeromin's suggestion about comparing different methods of bet selection would be interesting.  My fear is that there wouldn't be any difference in accuracy between the three.

I'm assumig there will be no difference. But what if there is? Wouldn't that be a shocker? Even if they all end up losing the same amount, the behaviour of the system might offer betting opportunities, who knows.

I have been playing using my suggestion regarding L's and W's.  It slows progress down quite a bit, but it has stabilized the system considerably.


I have played to +50 and didn't have to bet above the 10-10 level.  And that was only 1 time.


This can be played with any of the bet progressions I posted above.  I have been using the 2 in a row progression.


I wait until I have 2 of a dozen and 1 of a dozen in the last 3 spins.  I virtual bet on the 2 dozens other than the one that showed twice.  If my virtual bet wins then I am ready to bet for real unless the last spin caused me to have 1 of each dozen in the last 3 spins or 3 of a single dozen. I never bet for real unless I have 2 and 1 in the last 3 spins.


After a virtual win, I start betting for real.  As soon as I lose or have a dozen hit 3 times or not have a repeat dozen in the last 3 spins I stop betting.  If I quit because I lost, I don't start betting again until I have a bet situation that results in a virtual win and then I start betting for real.  If I stop betting because I had say 1-3-2 dozens in the last 3 spins or 3-3-3 dozen in the last 3 spins as soon as I have a valid trigger ( 2 & 1 ) I start betting.  I only have to wait for a virtual win to resume betting if I had a Loss or Losses that caused me to stop betting.


This new method has cut my betting opportunities by 2/3, but I feel that it has increased my win percentage quite a bit.  I know that one session to +50 is nothing and it could just be a fortunate sequence.


I'm not so naive as to think this will never lose, but I am naive enough to hope it can win enough to make it a playable system.

For those of you who want what I think is a very solid bet progression method, I will suggest the Hollandish method for double dozens.


The Hollandish method for double dozens is a little complicated to explain, but in fact it is very simple to play.


As soon as we lose a bet at 1-1, we write down 1 1 on our recovery line and we immediately start betting 2-2.  If we win, we cross off the two 1's and we are fully recovered and can re-set to 1-1.


If we lose the 2-2 bet, our line will be 1 1 2 2 and we bet 2-2 again.  As long as there are 1's to be recovered, we only bet 2-2.  As soon as all the 1's are recovered and we only have 2's in our recovery line, we bet 3-3.  If we have 1 1 2 2 and we win our next 2-2 bet our new recovery line will look like this: 1 1 2 2 and we will start betting 3-3 for recovery.  If we win our 3-3 bet, we will cross off one 2 like this: 1 1 2 2.  All odd units become profits.  Our next bet is again 3-3 because we have a 2 still to be recovered and we can't bet more than 3-3 as long as we have any 2's to be recovered.  Let's say we lose our next 3-3 bet, our recovery line will be: 1 1 2 2 3 3 and we will continue to bet 3-3.  If we win our next 3-3 bet, our recovery line will be: 1 1 2 2 3 3.  We will have 2 units in profits and start betting 4-4 to recover our 3's.


We continue to do this until we cross off all numbers in our recovery line or if our profits from this series becomes more than the number of units left in the recovery line, we can zero out that recovery line and reset our bet amount back to 1-1.  This latter method is the conservative method and should be used if our bet sizes start getting too large.

Hi George
for the Hollandish progression, do you recommend the above bet selection for double dozens?
thanks

Catalyst,

The Hollandish bet progression does work fine with this bet selection method.  So far, it is a steady winner. 

The Hollandish is less volatile than the parlays because it would take a really horrendous series of spins to cause an overall loss.  Unlike the parlays which have a definite series that if you lose at all the levels, you just take the loss, with the Hollandish progression, you could continue indefinitely.  With a bad enough losing streak, even with the Hollandish system you can get quite a bit in the hole and a stop-loss is a good idea to guard against the unusual.

In the limited testing I've done with this system, I've only gotten to the level of betting 7-7 to recover 6's.  The most I was down was about 35 units.

The 2 in a row progression is working well also.  But it is a martingale type progression and therefore comes with a pretty good bite every now and then.

The negative with the Hollandish system is if you reach a high bet level, say 10-10 and then you go into another high loss to win period.  This can drive you into the hole, but this is the problem with all progressive type betting systems.  If the loss to win ratio gets too high, you're going to lose no matter what bet system you use.  Even with  a flat bet.

This was the hardest session I've had.  I'm going to play it betting the Hollandish progression and see how it does.

I think the above playing method is very sound, but it doesn't suit my playing style at present.


Here's my new bet selection methodology.


Our main bet is to wait for a dozen to hit twice and a dozen to hit once in the last 3 spins and bet on the dozen that hit once and the dozen that didn't hit in the last 3 spins.


Previously is had a No Bet situation when I had either no repeats in the last 3 spins or all of the last 3 spins be the same dozen.  Now, if we have no repeats in the last 3 spins, in other words 1-2-3 or 2-1-3 or 3-2-1 or 3-1-2 etc... we bet on the last 2 dozens to hit.  In the above 4 examples we would have bet on the 1-2 on the 1st one, 2-1 on the 2nd one, 3-2 on the 3rd one and 3-1 on the 4th one.


If we get 3 of the same dozen, in other words 1-1-1 or 2-2-2 or 3-3-3 we bet on this dozen and also on the farthest back dozen to hit.  If we have the following spins 1-3-3-2-1-1-1  our next bet would be 1-3.  The 1 dozen is the repeating dozen and the 3 dozens is the farthest back to hit.


If you like the Stop betting after a loss and start betting after a win idea, it's still very strong and I recommend it.


The above change will give us a lot more betting opportunities and so far doesn't appear to water down our wins vs losses ratio.


A different bet progression is posted in Colbster's "Eggleston Betting Method 2" replay #8

hi George
i have gone through double dozens before extensively with Hermes leveller progression and martingale and and i had that time concluded that playing double dozens is not economical. but now i find it playable with your progression or hollandish. also i am thinking to employ Victor's famous LW strategy and virtual play.
thanks

Cat,

I hate to say it, but I can't see any difference in any bet on the table.  Since the math is the same, the only difference I can see is the time it takes for things to level out and the amount of money you need for betting more spots each spin.

If you have a winning method betting a single dozen, why can't you play the flip side and bet the other 2 dozens and win?

The Hollandish progression is a pretty safe, grinder bet method.  The bets can get pretty high at times, but with enough bank and patience, I've never tested a bet with it that I didn't eventually pull out of the hole.

As we know, anything can happen in roulette.  Case in point.  Recently I was returning from a business conference and my plane was delayed for 4 hours.  To pass the time, I thought I would do a test.  Since I had a quarter, I decided to see if I could win $1000 dollars betting a 10 step martingale.  That's a 50/50 bet.  I gave myself a 512 unit bank.  To give myself an advantage, I added a win for my side every 20 bets.  That gave me close to a 5% advantage.  I did well for about 400 bets and then I had 2 losses within 150 spins.  Wiped me out.  There are just no guarantees in this crazy game.

(Green Meanie, you posted the same thing twice. I removed it for you)

In the past, I found more luck playing the Double Dozens this way

look at the last 4 streets to hit, and play the other 8

So, (last) 2,7,7,1,4,5,2, Here the dozen (in streets) 1,2,4,7 has hit 5 times. This is high SD for a dozen (SD 3.2) so play 3,5,6,8,9,10,11,12

The quickest way to bet this is to look at the marque placing a chip on a number in the streets you see, as a marker. When you have 4 streets marked,  place a chip on the remaining streets. now remove the markers  to leave a 4 street gap.

I got very quick at that. You get some odd looks.

There is always a Dozen (in streets) that has hit 4 times at least (SD 2.9), or 6 ( SD 3.5)

Just a thought
