This is 2-4 streets bet. (FEEL free to test and share your result!),
Trigger: First spin--> place 2 streets, (on each side of the current hit street). Now keep that bet and spin until a *new* trigger appear, (a bet possible on both sides of the current hit street), when the new trigger appear, bet 2 more streets on each side of the current hit street. Now 4 streets are bet--> Begin Progression. (Stop and restart at any hit)
Progression: After the first trigger is bet -> you have 2 spins on the "bank", now if the New trigger hits directly after the first one, place bets an do 2 spins, after that double bets then double bets after each 2 losses in a row, (until hit). IF the new trigger hits after 2 spins--> only do 1 spin, then start progression (double, then double for each 2 losses in a row) IF the new trigger hits after 3 spins or more--> double directly after the new trigger is bet. (and start progression...)
