The vertical matrix system utilises a unique method of recording results.

For this sytem we will only be considering the dozens.

There are three dozens on the roulette table:

• Dozen 1 – (1 -12)
• Dozen 2 – (13 – 24)
• Dozen 3 – (25 – 36)

We will record results in respect to which dozen they are in, i.e 1, 2 or 3.

Results will be recorded in a 7 wide matrix, for example if we take these spins:

14, 32, 21, 24, 8, 13, 16, 2, 27, 6, 0, 19, 2, 30, 34, 28…

They would be recorded in respect to the dozen they are in and would be in a 7 wide matrix format as shown below:

Notice a zero is recorded as ‘0’, it is important to record the zeros.

The system

We continue recording results as above until we see a vetical ‘Quad’, this is a vertical line of four of the same number as shown below:

This is our trigger, we will now wait for the next vertical line of 3 to form and we will be betting that it WON’T become another ‘Quad’.

For example if the game continued as shown below:

At this point we would now be betting that the vertical triplet (shown in green) will NOT become another quad.

We are therefore betting against dozen 3, so we put one chip on dozen1 and one chip on dozen 2 as shown below:

If this bet wins, we are +1 and now wait for another trigger (quad) before we repeat the process on the next triplet.

If this bet loses, we wait for the next triplet to form and bet again that it WON’T become a quad. For example if we lost and the game continued like this:

We would now be betting against the triplet becoming a quad however this time, as we lost before, we would now be betting 3 units on each dozen.

We would be betting against dozen 2 so the bet would be 3 units on dozen 1 and 3 units on dozen 3 as shown below:

If this bet loses, we wait for the next triplet and repeat the process but we would now be betting 9 units on each dozen.

If that bet also lost, we would wait for the next triplet and repeat the process but would now be betting 27 units on each dozen.

If that bet loses, stop and start all over again, i.e wait for a trigger and go back to betting one unit on each dozen.

If at any stage you win, you are +1 and start all over again.

It is important to wait for the first quad as a trigger before you begin betting on the next triplet. This is because a vertical quad is a rare occurrence and we are essentially betting against five of them forming in a row.

If five quads do form in a row then, following the progression of 1 – 3 – 9 – 27, you will have lost a total of 80 units.

This is a very rare event however and it is likely that you will have won much more than 80 units before you ever see five quads in a row.

Another important note is the zero. If a zero comes at any time, it voids any triplet or quad that may be forming. Any number above a zero is void so in this situation:

3

3

0

3

You would NOT bet.
