My ’system’ idea, I call “Zero Tolerance”.

For single zero roulette.

Stake:

Stake 1 unit on 1st Dozen (1-12)
Stake 1 unit on 2nd Dozen (13-24)
Stake 0.5 unit on numbers 25-30
Stake 0.5 unit on ZERO

You are covering 30 numbers + the zero on the roulette table for a 3 unit total stake. You only win when the 0 comes up.

Play same stake every spin until you win or losses are -18 (end of session).

Most spins you will get your 3 units returned.

If the number spun is 31 to 36 you of course show a loss of 3 units.

If 0 comes up with no losses you win 15 units
if 0 comes up and you have had 1 loss then you win 12 units
if 0 comes up and you have had 2 losses then you win 9 units
if 0 comes up and you have had 3 losses then you win 6 units
if 0 comes up and you have had 4 losses then you win 3 units
if 0 comes up and you have had 5 losses then you will be LEVEL
The 6th loss results in a net loss of 18 units. End of session.

It can be played with low value or high value chips. You only play 3 units per spin. Your max profit per session is 15 units. (Zero came up with no losses.)

Single-zero roulette tables are getting harder and harder to find in the casino. However, you should be able to find one near you by searching the internet.

Well, there it is, a simple staking plan without using many chips.

You need patience and tolerance though whilst you wait for the zero to show up.
