There are players like to cover a large area of the carpet.

It is not very good practice if the house advantages is high.

If there is a return on zero for EC bets they should be used so much as possible.

At a NOZ we can cover more without the cost to the house.

If we cover two dozen and at the same spin two columns, we have covered 32 numbers.

We win only on 16 numbers.

Lose small on 16 numbers.

Lose all on 4 numbers. (on NOZ otherwise 5 or 6)

Can this work?

I have done a number of play (several 100), and won them all.

It must be played on line with very low starting bets.

The progression is negative.

On a total loss we progress using hexagonal* series.

On a partial loss we progress using triangular* series.

This numbers are figurative series with some interesting properties.

We increase the bet after every loss, and stay on a win (exception see next line).

If we do not need the full bet to reach new high we may reduce it.

We start with one cent each bet, and should be ready for betting much more.

The winning rate is faster than I thought.

* A triangular series is adding the spin number to the last bet.

1 =0 + 1 = 1

2 = 1 + 2 = 3

3 = 3 + 3 = 6

4 = 6 + 4 = 10

0, 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91, 105, 120, 136, 153, 171, 190, 210, 231, 253, 276, 300, 325, 351, 378, 406 …

**

A hexagonal series is the same as triangular every second step.

1, 6, 15, 28, 45, 66, 91, 120, 153, 190, 231, 276, 325, 378, 435, 496, 561, 630, 703, 780, 861, 946...
