SOSO roulette strategy

I tried this strategy once, in what casino I do not remember. I remember that the balance was approximately on a place. But sometimes and it's a good result too.

"SOSO" strategy - Same, other, same, other, etc. It's a very simple roulette strategy!
For example:
1.If red - you must bet on red (same).
2. If black - you must bet on red (other)
3. If black - you must bet on black (s)
4. etc.
