This is a very simple system, you simply bet one unit on each of the last four numbers that have come out! (including the immediate last one).
However there are some rules that need to be followed which will be explained below.
We must first wait to ‘qualify‘ a dealer, this is done when the fifth spin matches one of the previous four spins. For example:
1st spin = 15
2nd spin = 17
3rd spin = 31
4th spin = 2
5th spin = 31
As the fifth spin was 31 and matched the third spin, the dealer is now ‘qualified‘ and we can begin to bet.
So for the next spin we would bet one chip on each of the last four numbers i.e 15, 17, 2, 31. (Notice how the first 31 is dropped and the latest 31 is added to the end).
Say the next spin is 5 and we lose, our next bet would be one chip on each of the last four numbers i.e 17, 2, 31, 5. (we always bet the most recent four numbers).
Say the next spins is 2, we win 32 chips! Our next bet is then one chip 17, 31, 5, 2. (Remember, we remove the first 2 and add the latest 2 to the end, always betting the most recent four numbers).
The next spin is 8 and we lose, our next bet is the one chip on 31, 5, 2, 8.
The next spin is 12 and we lose again. We have now lost twice in a row and this is our signal to stop betting. Either leave the table or wait for the dealer (or a new dealer) to qualify again.
All 4 spins MUST be by the same dealer, the key to this method is dealer bias, therefore you must be sure to qualify the dealer and not the table.
If there is a change of dealers while you are betting, you must immediately stop betting (or re-start your count) and qualify the new dealer, even if it is a dealer you have won with in a previous session.
The main problem with this strategy is being able to jump into the game and out of it at the time that the dealer qualifies. You may want to consider playing at two different levels.
You may wish to bet something like the black or red for the table minimum as a bet purely to remain at your place at the table, and then this method for $5 or more on each number when the dealer qualifies.
It could sometimes take an hour or more to qualify and then you may only make two bets if they both lose. You would then go back to waiting for a new qualification.
You should be able to do this with a $100 bankroll (using $5 units for this method of play). That
would allow $80 for this method, plus $20 to keep your place at the roulette table.
If you lose, then you have lost the $100, or most of it. If you win, then you will win 32 units on that bet (35 minus the 3 which you lose, and the one unit on the winning number will remain there for the next bet).
If these are $5 units, then you will pick up $145 (which is your $100 bankroll plus an additional $45) and still have $20 on the table for your next bet. If that also wins, then the same thing will happen again.
Remember to always start over every time there is a dealer change or two consecutive losses. This is essential when you are using this strategy.
