I changed my mind!

Now I think it's better to play like explained below.

4 unit bankroll with the aim of doubling it to 8 units playing red or black.

Try to win two out of three sessions

We start with 4 units and we use them to win 4 more units. It's a very clever positioning of the won units that makes this a strong method. Explanation follows.

Here's our chart. It has 4 patterns. Memorize it. It's easy to do.

1 1 1 1 = 4 units

1 2 1 1 = 5 units

1 1 2 2 = 6 units

1 1 2 3 = 7 units

Start with 4 units 1 1 1 1

Bet the 1st unit. If it wins, put it on the 2nd unit like this 1 2 1 1.

Bet the 1st unit. If it wins, put it on the 4th unit and move 1 unit from the 2nd position to the 3rd position like this 1 1 2 2.

Bet the 1st unit. If it wins, put it on the 4th position like this 1 1 2 3.

Bet the 1st unit. If it wins, we have won 4 units. Goal accomplished.

But what if we don't win 4 times in a row?

We always bet the leftmost position and we always try to re-create the above positions.

We bet the 1st unit and if we lose, we bet the 2nd unit.

If we win on the 2nd unit we replace the 1st lost unit and we have 1 1 1 1 again. Start over.

If we win the 1st bet we will have 1 2 1 1. If we lose the next bet we will have X 2 1 1.

The leftmost number is 2 which we bet. If we win, we will have 6 units. We look at our chart and see what pattern is made up of 6 units. It's 1 1 2 2. That's our new pattern and we now bet the leftmost position, the 1st position or 1 unit.

Note: We only recreate our chart after a win. Everything stays in place after a loss.

If we win 2 times and then lose 2 times we will have X X 2 2. Since we just lost we don't re-arrange the units so our next bet is 2. A win here and we are re-arrange our chart to 1 1 2 2.

If we lose 3 times we will havel X X X 2. We bet the 2 and if we win we will have 4 units and anytime we have 4 units after a win, we re-create the 4 units pattern, 1 1 1 1.

If we have the 1 1 2 3 pattern and we lose 3 times in a row we will have X X X 3 so we bet 3. If we win we will have 6 units so we re-create the 6 units pattern, 1 1 2 2 and bet the 1st 1 next.

As you can see, the way we move the units around maximizes our chances of staying alive until we can win our 4 units.
