How many gambling sites are you playing and do you use the same strategy? I'm playing on at least 4 sites now and uses a different variation on the martingale and some guessing method and I found out that I have good success implementing a method on one gambling site that is not effective on other gambling sites, how about you?
I only play at one gambling site and I do use some strategies to increase my chance of winning. This site I've been playing to is somehow fair unlike other sites where I used to play. I use strategies in playing poker and other game and it does somehow work. With regards to strategies you must update it for time to time because eventually it wouln't work.
