Every machine in a casino pays off according to a random number generator. This generator provides that a winning combination will likely hit a certain amount of times, but not necessarily. The times when a player is hitting everything in sight makes a person perceive that they can't lose and that they will continue to win forever if they play that one machine, but that just isn't the case. A player will eventually start to lose if he or she continues to play long enough. Players can maximize their chances at playing at a certain machine, however, even though they can't find a lucky machine.
Many machines offer differing paytables for gamblers.
By playing at machines that offer the best paytables, players give themselves a better chance of staying ahead of the casino by winning more money when they likely will hit at least once. Also, if players use correct strategy at games, they will increase the odds that they will win. Finally, if players join a casino's slot club, they can win extra money while playing their favorite machines. This extra money will provide a gambler more money if winning or help players lessen their losses if they are on a losing streak. Still all of these things can't guarantee that a player will win everytime they play a casino game.
