This is played with 37-9= 28 Numbers (European Wheel).
Procedure: Wait for a hit in column 1 or 3. When that happens place 4 quads inline with the column hit, at the two other unhit dozens. Also put 1u on the opposite column (column 1 or 3; if column 1 hits, place 2u on column 3, if column 3 hits place 2u on column 1) etc.
For an example,
Number 1 hits (column 1) Now 2u are placed on column 3 (numbers 3-36) And 4 quads are placed inline with column 1; Quads 13/17, 19/23, 25/29, 31/35.
Progression: Double bets for each loss. Also, for the next bet go one step BACK in the progressionline, until reached 1u again;
1-2-4-8-16 etc....let's say you end up winning at step 4 (8u), the next bet would be step 3 (4u), if win again next bet would be step 2 (2u)....and so on.
Fist test was played with 1u bets, (wingoal +100u, stoploss -100u)
Test 2. As you can see in this chart drawdowns are kept at a minimum (even after 2-3 losses) thanks to this progressionmethod, recovery is fast.
Correction of procedure
Also put 1u on the opposite column -- it should be Also put 2u on the opposite column
Test 3.
Test 4.
