Gambling is a curious mix of luck, skill and patience, knowing and playing the odds, knowing when and how to lose and much more besides.  The idea that gambling can be boiled down into an easy formula is bordering on the absurd.  A person could go into a casino or log-on to an online casino on successive days, gambling exactly the same way and return with wildly different results.  Sometimes one of the harshest lessons to learn about gambling is that at times you are up and others you are down.

Try not to be lured by the fallacy that short-term outcomes have the same frequency as long term ones.  You are not playing against a thinking creature that will use its previous experience to try and outwit you.  A ball bouncing in a roulette wheel has no memory of what it did previously.  If you are at a roulette table and the ball lands on black a number of times successively, it does not routinely imply that the next time the wheel is spun that the ball will again land in black.  The odds of it landing in black again are somewhere around the 50% mark (a little less because of the zero) on the wheel.

Gambling is difficult enough, without falling into a trap such as this, trying to second guess (based on faulty logic) the bounce of the roulette ball or whatever is appropriate to the game that you are playing.
