The Black and Red Doubling System

This system is the most simple and with every win it provides 1 unit (£1 or $1) profit. However, the losses increase exponentially so if your float (balance) is not big enough it can clean you out very quickly! So this system worked, and it worked as predicted, but the casino's have realised that this system is being used and have employed methods to stop it, which means it used to work but doesn't anymore.

Feel free to try this on the play table of a casino.
Click here to see a list of casino's, their features, and in theory which systems they would work with. (Good for using with play money and testing my claims).

 The System Itself

You start by placing a bet on the colour of your choice (lets say Black first).

Your first bet is 1 unit, from now on I will use £ as an example, so you bet £1.

 You can assume a unit is more than one of a currency, so it can be £1, or £2 or £10, but when I mention betting you must multiply the amount I say to bet with intial bet. E.g. If I say bet 1 you bet $2 to start of with and I then say bet 2, you bet $4. IF this system worked well, doing so would maximise profits - but it doesn't!

Now, if you win, you have got £2, so you spent £1 and got £2 thus making a profit of £1 - that's a good start.

If you didn't win, you bet again on the same colour, doubling you previous bet.

You keep repeating this until you finally win.

After you win, switch colour and start again.

On some play tables this will make you lots of money.

I have noticed (as detailed on the casinos page), some casino's let you win using this method with play money, but not with real money!


The 'Profits'

Lets assume you lost a few times:
You bet  £1   (you have so far bet £1    and if you win you get £2    and make a profit of £1).
Then bet £2   (you have so far bet £3    and if you win you get £4    and make a profit of £1).
Then bet £4   (you have so far bet £7    and if you win you get £8    and make a profit of £1).
Then bet £8   (you have so far bet £15   and if you win you get £16   and make a profit of £1).
Then bet £16  (you have so far bet £31   and if you win you get £32   and make a profit of £1).
Then bet £32  (you have so far bet £63   and if you win you get £64   and make a profit of £1).
Then bet £64  (you have so far bet £127  and if you win you get £128  and make a profit of £1).
Then bet £128 (you have so far bet £255  and if you win you get £256  and make a profit of £1).
Then bet £256 (you have so far bet £511  and if you win you get £512  and make a profit of £1).
Then bet £512 (you have so far bet £1023 and if you win you get £1024 and make a profit of £1).


As I'm sure you will have noticed by now, if you follow this bidding system, when you bid n overall you have bid 2n - 1 , and I'm sure you can see that the amount you spend really adds up if you don't win. By bid number 10 you have spent £1023 and won nothing! One more bid and you will have spent £2047 if you haven't won! OUCH!

The losses!

As you can see, every time you don't win your losses practically double. Now you first loss is £1, second is £2, and so on.

This means that if you get a streak of one colour coming up, the colour you are not betting on then you will  built up a big loss, quickly.

In my example above I show that on the 10th run in your 'bad' streak you have lost £1023. Now you might be thinking this isn't very likely because of the law of averages etc. etc. (See my Law of Averages section). Using my statistical analysis and prediction software, on more than one occasion I got a streak of up to 16 numbers where the colour I wanted did not turn up. Sometimes they were not a streak of just 1 colour, sometimes it was a green that interrupted the streak before it continued, still yielding no profits as the desired colour did not come up.

The money lost on a streak of 16 would be (2^16) - 1 which is  £65,535!

If you can afford to lose this (and potentially more - as I only ran the test for about 5 hours) then go ahead and join a casino! But otherwise please ignore this betting system.

The real life result

I started using 888 as it was recommended for using this system.

This was the first system I tried, and I wrote an application to check the last colour and bet as appropriate. On the 'play money' tables this worked like a charm, the longest streak it got was 7 which requires a float of £127, and on this casino it was in dollars so thats only about £70, and on top of that I got about a $40 bonus, so I had nearly $170.

Well, I ran my application on 'Real Money' with $170 and it cleaned me out in less than 10 minutes. It got a streak of 9 which would've required $511. In many hours of testing on the same casino's play table this never came up!

The 16 colour streak

After finding another system  I had to find a casino that would allow me to spin the wheel without bidding, which 888 wouldn't allow me to do. So I found Golden Palace which allowed this, and I wrote another application that looked at the numbers that came out (and calculated their values, for use in other systems) and after running this on a real table, with no bids, logging the numbers (and colours) that came out, it got a streak of 16 of one colour within the first hour. This also happened when looking for all other pairs - the odd/even and the high/low (1-18/19-36). More detail is on the 'Other Systems' page.

The variations

This is system primarily described using black/red but it would in theory work on any pairs system. However it does not.

Conclusion

In real money and some play tables this system does not work. I get to a loss of at least £253, potentially more!
At the end of the day - unless you have a nearly unlimited float (probably over £100,000 to be safe) there is no point in using this system - and even then it's risky.

More Information

To find out why this should work but doesn't read the 'Law of Averages' Page. Also see the 'Other Systems' page because it describes how less risky variations of this system still, eventually fail or don't yield profits in the long-run.
