DD,
I posted a strategy on how to use the columns,
(2/1) I deleted it cos it did not make much sense to many. Made sense to me though.
Anyway;

Bet on centre/right and this "formula" I had tried seemed to make me $100.0 per hour.

here we go again,

observe the table and take score for 15-30 mins. Tick L-C-R
Observe the spinner.
Observe the change of the score when the spinners rotate.

We assume $5 chips (have plenty)
1 chip on cntr
1 chip on right ( or left, up to you or the score)

Bet 2 chips: cost $10.00
if win, collect, bet 2 chips again.
Stick to the same chosen columns, dont's cahnge.

If loss, and this is where I had problems explaining the strategy,
But you double up, PLUS one extra chip on each column as if it's still your first bet.
It will eventualy win.
Once you win, it's back to 2 chips.
That is why one needs to observe for 15-30 mins and get to understand the spinner.
When the spinners rotate tables, it messes your cycle.
The new spinner has a different style of spinning to what one has become used to.

I hope this makes sense.
