Problem is with the strategies that casinos do not seem to like them... most of them I visited, you are not allowed to do so
Nothing much strategy might work in roulette as you can close your eyes and bet either on red/black or greater or less than 18 etc. Nothing much of brain needs to be used in such games as if you have a good luck you will win it or else if lost just stay away from the gambling unless you have lots of money to lose.
