Terminator, this is what I do.

place 1 unit on #1, .

after 3 spins no hit, do not remove.

add 1 unit on double street.(1/6)

after 2 spins no hit, do not remove any bets, add;

1 unit on the street (1/3).

after 1 spin if no hit anywhere still, add'

1 unit on quad 1/4.

after 2 spins if no hit,add

1 unit on split 1/2.

after 4 spins if no hit anywhere add

1 unit on #1 for 4 spins . (at this point you have now 2 units on #1.

total investment = 17 units.

keep playing til you hit your main number.

if no hit, switch to another hot number. you can also play at a 2 unit base bet if you wish and it wont be bery risky since the investement is 17 units.

lots of upside potential for the agressive player.

let me know what you think,

best
