A space or place for receiving something, as a coin or a letter. (plural: slots) Also: the position of a coin or other item in a slot on a machine. (American Heritage Dictionary of the English Language, Third Edition)

A space in a computer for installing an expansion card such as an ISA, PCI, or AGP slot. Slot is also a generic term for the individual compartments in a motherboard where such cards are installed.

The most important thing to remember when playing slots is that winning is entirely random. The reason is that all modern slots have a random number generator, or RNG, that selects the sequence of symbols stopped on each reel. These computer chips retain no memory, so a spin’s result is determined by the numbers generated within a massive spectrum and not by any events that have occurred in previous or subsequent games. That means that trying to predict the results of a spin is futile and only serves to waste your time and money. The most effective slots strategy is to decide ahead of time how much you can afford to spend and then stick to that limit no matter what happens. This way you won’t get caught up in the excitement of the game and lose more money than you can afford to spend.
