This is 4 numbers bet, FLATBET.
Procedure: Bets are placed within the current dozen hit; -All numbers of the same color within the dozen hit except That particular street hit containing 2 number of the same color are NOT bet. (4 numbers bet, for 9 spins then STOP) The color bet is determined by the current street hit containing 2 numbers of the same color.
For an example:
Dozen 1 is hit (number 12 RED) now that street consist of 2 BLACKs: 10 & 11. (These are NOT bet) but all other blacks are bet within doz 1; numbers 2, 4, 6, 8.
Dozen 3 is hit (number 36 RED) now that street consist of 2 REDs: 34 & 36. (These are NOT bet) but all other reds are bet within doz 3; numbers 25, 27, 30, 32.
First test was played with 5u bets, (wingoal +500u, stoploss -500u)
Again, interesting approach!
