My first time watching someone play Blackjack, I observed this person for about 1 hour just trying to learn their strategies and watch how other people play. I had only $80 on me for my trip at the time and I wound up turning that $80 into $300 in less than 30 mins!
I hit the biggest Jackpot of my life playing Mammoth Power at the Venetian High Limit Room. The minimum bet was $30.00 hit for over $10,000. Check out the video here https://www.youtube.com/watch?v=6J-iBlKHiIc
