Here is the list of casinos for which the method works
I have linked the 2 online casinos I won with.I suggest 2 other ones for US players (also valid for non US residents).
Park Lane Casino
Use the European Roulette (Zero Spin) or the "easy roulette". The bets start at 1 Dollar which allows using my method.Be careful not to try other lovely games as they look very cute. You are not here for that!
Unfortunately, UK players are not accepted.
