I found a way how to win in roulette every time, I only bet on reds or on blacks.

If you bet $1 on reds and it goes red you win $2.
So I bet $1 on reds, if it goes black I bet $3 on reds, if it goes black bet $8 on reds (I always multiple my previous lost bet around 2.5).
If it AGAIN goes black bet $20 on reds, if this time it goes red I win $40.
So I bet $1 + $3 + $8 + $20 = $32 and I win $40 so I just made $8 and it took me around 2 minutes.

Did someone ever paid you $8 for 2 minutes work?
If I play for 4 hours I make $300-$500, EVERY TIME.
Now all you have to do is find a casino that allows progressive betting in roulette.
