# Columns to Dozens Switcher

Here's a little secret for you- this is one of our favourite roulette systems. We normally play it with a Triple Martingale progression so be warned, it's pretty aggressive. So you are going to need to start off with small bets, or you'll need deep pockets and a table with a decent sized betting limit on the outside bets

We sometimes even play this with the Even Money Switcher system, switching between the two systems when we feel the need.

Let's get one thing straight before we start. This roulette strategy will not improve your odds at the roulette table. No system will do that. We play it because it gives us a good system to pick our next bets- it take the emotion out of the game and it has worked for us in some sessions. You cannot get rid of the house edge. The answer to the question: How to Win at Roulette? is the following: choose your table wisely (don´t play on a wheel with 2 zeros, always play European Roulette), extend your winning streaks and cut short your losses.

OK, with that out of the way, let´s look at the Columns to Dozens Switcher.

How to Play the Columns to Dozens Switcher.
This is a hedging strategy that aims to cover a decent amount of the table. The flip side of that is that a losing bet is expensive. You pays your money and you takes your chance in other words (to coin a phrase).

Start off by setting a profit target for your session (the amount of money that you want to win, and the point at which you will leave the table). You also need to set a stop loss- that level at which, again, you walk away. This is a useful exercise for any system by the way.

You are going to be covering just under 2 thirds of the table on the Outside Bets, specifically the Dozens Bet and the Columns Bet. Start off how you like and cover 2 of the 3 available, so 2 dozens or 2 columns. Another variant which is similar to this is the Six Line Quattro system.

If you Win the Bet
On your next bet, you are going to flip your bet (from columns to dozens or from dozens to columns). All you are doing here is mixing your play up a bit. Theoretically it makes no difference as each spin is a mutually exclusive event, but we prefer to try and randomise our play, at least a little bit. Call us superstitious! Follow a flat betting profile, continue to bet the same amount as your initial bet.

Bet on the 2 columns or dozens that didn´t come in, and continue like that, switching between the columns and dozens each time. You can also bet on the dozen or column that came in, plus one other- it´s up to you, just stick to some simple rules so that you do not have to make any decisions on what to bet during the session- you just follow your system- all the decisions are made before the first spin of the wheel.

If You Lose the Bet
You will lose a bet at some point. It´s extremely unlikely that you don´t unless you play a very short session. When you lose a bet, this is where the aggressive part of the system comes into play, the Triple Martingale.

After a loss, repeat your bet on the previous spin (so stick with the same column or dozen), but triple the bet on each outside bet. So, if you were betting £10 en each column (£20 in total), you are now betting £30 on each column or dozen, so a total of £60. We told you losing was expensive! What you are trying to do here, is to claw back your loss from the previous spin. But because you are paying to cover just under two thirds of the table, you need to triple your bet rather than double your bet as you would do playing the standard Martingale on say the even money bets.

Careful!
If you are tripling your bet after a loss on 2 bets, you can imagine that your bets ramp up very quickly! We don´t recommend that you progress more than 3 steps along this Triple Martingale, or at least keep your initial bets low. This is why it is so important to set a stop loss on this system- don´t just blindly triple your bets until you hit the table limits unless this was your plan all along and you are happy to risk this amount.

You are hoping that you win the very first bet after a loss, or at least the one after that. Once you have won, reduce your bet back down to your starting bet level.

Examples
Let´s have a look at some examples.

1. Roger starts betting with £10 units.
He places £10 on the first and third columns. He wins.
Amount bet £20.
The number 13 comes in (lucky for some!) in the first column.
Payout £20, plus he gets one £10 bet back = £30.
Profit: £10.
Roger switches to £10 on the first and last dozens, as the middle dozens hit last.

2. Anna is betting £10 on the 2nd and last dozens.
Red 5 comes in and she loses the first bet, so she triples her bets on the same dozens (£30 on each).
32 hits- a win!
So here´s her cash flow:
1st bet: £10 + £10 = £20. She´s Twenty quid down.
2nd bet: £30 + £30 = £60. She´s £80 pounds down.
One bet wins. The payout is £60 plus she gets the winning bet back of £30, giving her £90.
Her overall profit is £10.
Now she reverts back to her original bet of £10, and switches to the 1st and third columns which didn´t hit last time.

3. Juan loses 2 bets and wins the third one.
Initial bet £20.
2nd bet £60
3rd bet: £180. Total bet is now £260
Juan wins this one, so makes £180 plus he gets one £90 bet back = £270
He is now £10 up.

You can see, just like the Martingale, that if you lose twice, you will end up betting £260 to win £10. Your payout at this point is only 3.8%. The longer you progress up the Triple Martingale, the worse this ratio becomes. You do not want to be spending much time on this escalator.
Having said that, you are covering just under 2/3 of the table each time. That´s the trade off. The important thing is to understand how this roulette strategy works and you can then make an informed decision based on your budget and appetite for risk. Always play within your means.

You can also "Randomise"
Normally we would switch between columns and dozens after every bet. You can also throw in some additional "randomisation" and choose whichever 2:1 outside bet takes your fancy.

Columns to Dozens versus Even Money Switcher
I guess you could say that this system is a variant of the Even Money Switcher system that we have also shared in this strategy section. So how do they compare?

Well, the main difference is the table coverage and the betting profile after a loss. In this system, you are covering a third more numbers, but it is more expensive trying to claw back your profits after a loss.

Also, in the Even Money Switcher, if you can find a French Roulette table that plays La Partage, you can get the house edge down to 1.3% because the casino will give you half your money back if the ball drops into zero. That rule doesn´t apply to the columns or dozens bet. Sign up at UK Casino Club and play the French roulette with their 700 bonus and you will benefit from La Partage.

Which one do we prefer? Guess what? We switch between both of them ;)
