I was a dealer at a casino before going to graduate school. I dealt craps, roulette, and blackjack. I was a first-rate dealer. I’m not at all saying this to brag, but only to indicate that I know what I’m talking about. Quite frankly, I’m far more often embarrassed about my tenure as a dealer than I am proud of it.
You can win money playing poker, but that’s only because you’re playing other humans, and not the laws of mathematics.
On every table-game, however, there is a built-in mathematical advantage for the house. For example, in roulette, the odds of your number coming up are 1-in-38. However, the payout is only 1-in-36. In other words, the actual odds include the “0” and “00,” while the payout-odds do not. That’s a 5.26% advantage for the house on every spin. Another way of thinking about it is to think of what would happen if you covered every number with a chip: you would lose two chips on every spin, since you would win 35 chips but you would lose 37. You are playing the laws of mathematics, and you will not winÑnot in the long run, anyway. There is no way to beat the odds; there is no “method” for winning. The only winning move is not to play. Anybody who tells you anything different is a fool.
Concerning blackjack: Most casinos now employ six decks in blackjack. Not only are you not able to count cards if six decks are used, but you will be escorted from the casino even if they think you’re trying to count cards. Give it up.
The games with the biggest house-advantages are the money wheel and slot-machines. These games also tend to attract the least intelligent gamblers. That’s not surprising.
Casino-gambling is like the lottery: it’s a tax on greedy people who are bad at math. The only other human inventions I can think of that are as stupid as casinos are religion and astrology, and all three have quite a few things in common, most notably, suspension of reality.
However, casinos are completely trustworthy. They have no reason to be dishonest, and every reason to be honest: they have the laws of mathematics and human greed working for them, and dishonesty can only hurt them. That casinos exist in the first place should tell you everything you need to know about them.
My advice: get a real job.
