The first thing to understand about slot machines is how they determine the winners. These games use a computer program called a random number generator (RNG) to continuously generate numbers. It is these numbers that determine how a particular reel will stop after you press the spin button.

An important fact to remember is that this process is completely random, and there is no way to predict what will happen during this or that spin. Another important fact that must not be forgotten is that each spin of the reels is a completely independent event. This means that the results of the previous spins have NO effect on the results of the next spins.

The latter fact says that the random number generator is programmed in such a way that the casino has an irresistible mathematical advantage over the player. If you play long enough, the casino will certainly be in the black just because the game is set up that way. This is not to say that you cannot win in the short run, but it has nothing to do with choosing a hot or cold machine.
