slot

A position in a group, series, or sequence. Also, the movable position on an ice hockey rink in front of the goal between the face-off circles (usually X or Z) that quicker guys and shifters like to play to avoid getting grabbed by the opposing team’s defenders.

Until the 1980s, slot machines were mechanical, and they had a limited number of symbols that could appear on a reel. However, once the first electronic slot machines were built, manufacturers were able to use computer programs to weight specific symbols. As a result, the odds of those symbols appearing on a payline grew far beyond their actual frequency on the physical reels.

The random-number generator is the brains behind any slot machine, and it constantly runs dozens of numbers every second. Each time the machine receives a signal, which can be anything from the button being pressed to the handle being pulled, the RNG sets one of these numbers. Then, the computer finds the corresponding location on the reels and stops them at that point. In this way, the computer determines what combination of symbols will appear on the reels and how much a player will win if he or she hits the winning combination. This process is why you can see a slot machine jackpot hit right after someone else leaves the same machine. In order to hit the jackpot, it takes split-second timing that would be impossible for anyone else to match.
