As we already know,
Apart from zero green,
There will...

Three different dz in 3spins
Only 2dz in 3spins,
3same dz in 3spins,
And 3zero in 3spins...

3different dz in 3spin=33% minus green, and 66% for other formations.


Single vs Series.
3different dz in 3spins, will repeat once, twice, thrice to infinite, but the most seen , rarely, up to six repeat.


Thus..
×××,
123,
×××.... (a single , of 3different dz in 3spins)
123,
321...twice...(a series of 2)
Xxx.

321,
123
231,..series 3.

321,
123,
213,
231....series 4, and so on to infinite...

Thus the simplest is SINGLE VERSUS SERIES (regardless of how many repeat)

The probability of single/series=66/33% minus green.

The probability of series of 2,  become series3=33% minus green.

"only 1dz or only 2dz/3spin ", also can single and series.

123,
121,...a single.
231...

231,
121,
323...series of two....
321....

123,
323,
311,
212,...series of 3,
132...

The probabilty of "non 3dz/3spins   "...single=33%    , series= 66%....minus green.

So how to bet?
When you see 3dz/3spins, you may bet...

123  that 3dz/3spins matrix.


Bet next matrix, may 3dz/3spins, or "non 3dz/3spins"

One of the advantage, they are stable, meaning they highly LIKELY, to hit
Within Math Expectation.

So when you intend to bet Single dz only,
You wait for   " only 3dz/3spins.."

Say
123...now bet matrix also 3dz/3spins matrix.bet the last, third spin.
321...win...

123,
323...lose 1u.

123
111...no bet
132...win

123
222 no bet
121  ..lose 1u.

123
333
132..win
123..no bet
321 ..no bet  ...wait for virtual break, start anew....

There no edge, whatsoever,  but, the highly stable, (perceived), is helpful...

Seems that even matrix strategy will revert to  edge, and can't win in long term, thus we need to depend on luck
