Did you know, Casinos have metal balls and magnetic spin tables which are programmed by the staff mathematicians to allow them to make a profit depending on their profit and loss statements, when they need money, these magnets are turned on. (First watch to see if everyone is losing or winning, if they are losing hard. Bet on the split 0 & 00, or simply bet opposite to them)
When you see a table when the dealer has quite a lot of money, I suggest playing. First observe to see if the dealer is not busting to much, if the dealer is busting go for it. If the dealer is constantly getting 21's, leave. I'm talking 3 sets of 21's in a space of 6 rounds. Depending on the table the electronic card system could be rigged to also obtain a profit when needed by the casino. (First watch to see if blackjack is being dealt on the dealer, if it is. Wait till the players are on a winning streak)
Poker Machines are connected to the internet nationally. Depending if your winning, someone on the other side of the country is losing on the same type of machine. If your losing, that other person on the other side of the nation is winning. So pretty much it should be a 50% chance to win, but it isn't. This is were the profits from casinos come in to take your decent chance away for their profit. (Don't even bother)
Play this at casinos if you plan on making money out of it. Since you are not versing the casino, you are versing other people; Not a program, You can't beat a system even if you were Bill Gates. (Practice at this, never reveal your emotions during game-play even if they are fake, a profitable gamble)
