In aviation, a slot is an opening in the wing of an airplane that carries a flap or ailerons. A slot also refers to a position within a group, series or sequence.

Unlike the old-fashioned mechanical reels, modern slots have no physical reels. Instead, they use computer technology to produce random results every millisecond. The numbers are then cross-referenced with a table of symbols and payouts to determine the probability of each symbol appearing on a particular reel. The odds of each possible combination are calculated using a simple formula.

Many people are curious about how slot machines work, so here’s a quick overview of how it all works. The first step is for the RNG to generate a random number for each symbol on each reel. This number is then recorded in a memory chip in the machine, and it is cross-referenced with a table to record where that symbol should appear on the reels.

The UNLV Oral History Research Center has an extensive interview with Redd that details how he foresaw ways to incorporate emerging technology into slot machines and overcome the weaknesses that Hirsch had identified.
