This roulette strategy called **Tiers et Tout** (a Third and All) is ascribed to Thomas Garcia.

Therefore, it is called Garcia Strategy or Garcia System sometimes.

The bets are always against the winning easy chance.

At first a third of the capital is placed.

On loss, the rest of the capital.

On win, again a third of the capital.

After two consecutive losses the offense is lost and the strategy restarts.

This strategy wins on every spin, as long as no series gets longer than two.

## a little tolerance

If a little tolerance is kept on stakes / capital,

some steps and therefore whole strings can be saved.

Example:

31. B 17/52

32. B 17/53 - if this single piece difference is ignored, the whole string could be saved.

As this strategy is a demonstration, I did not make those simplifications!

The dot-mode flowchart illustrates the step tree quite nice: Tiers et Tout

Possibly it would be possible to model this classic of the roulette strategies further

and more extensively in the simulator by means of factored inserts.

Who would like to accept the topic gladly! ;-)

This step tree is amazing and very nice illustrated with the strategy flowchart.

Are there other roulette strategies built with the usage of trees?

What is the limit in depth?

Gerald:What is the limit in depth?

How much do you think, you will need?

You won't beat roulette alone with a huge strategy!

Gerald:Are there other roulette strategies built with the usage of trees?

I remember these:

last SC win-4 loss+6

Inaudi Wechselmarsch

color slide back

simple chances bet increase and decrease

Gerald:What is the limit in depth?

Simple answer: there is no limit.

I am curious about how deep you will go!
