Half the wheel:

bet the *last hit* of these four groups

9 High red numbers

9 Low red numbers

9 High black numbers

9 Low Black numbers

these numbers correspond on the numbers on the wheel ; half the wheel has only black low numbers, half the wheel has only black high numbers etc.

this strategy works very well so far, from me playing this live ...anyway

progression, nine numbers negative progression

1 1 1 2 2 3 4 5 7 9

since tablelimit is 10 on db, and most other livecasinos i know?

or else a 9 numbers cyclic progression could be used, it will look like this

111222333444555666..... and so on, -1 step when hit (if you're betting 4u and get a hit you go down to 3u)
