The Double Martingale System has been around forever, just known as different names. I actually used it and came out a winner. I moved to Vegas before computers were big (1988) and used this system. It worked for me and I'm going back (left Vegas for a women - nuff said).
I had a fully furnished apartment that was $235.00 a month (utilities, swimming pool, all included). I had to make $8.00 a day to pay my rent.
My goal was $20.00 and I had a $1,000.00 bank roll. I would make 20 bucks before I started to lose. I did this for 18 months, till I went back to the midwest to get married. I LOST THAT BET!
Don't get greedy and have fun with it. I enjoyed people watching and meeting peeps from all over the world. I don't like working so I always kept my greedyness in check by keeping this in my mind. Stay cool or get a job!
I have made money from online casinos in the past. Goldkey Casino was a good one to play. They always paid me off plus sent me tons of bonus items. Clocks, suitcases, calculators ect. Made good Christmas Gifts (smile).
Best book that I ever read was 'The Weekend Gambler' by Major Riddle, who used to own the Dunes. I told a buddy about this book. He read it and it was the first time that he ever came home from Vegas with any money.
This book talks about more than just the games. It tells why the games are placed where they are and the mindset of the carpet's color. I highly recommend this book, if you can find it......
Take care and see ya in Vegas......
