All modern machines are designed using pseudorandom number generators ("PNRGs"), which are constantly generating random numbers, at a rate of hundreds or perhaps thousands per second. As soon as the "Play" button is pressed, the most recent random number is used to determine the result. This means that the result varies depending on exactly when the game is played. A fraction of a second earlier or later, and the result would be different.

It is important that the machine contains a high-quality RNG implementation, because all PRNGs must eventually repeat their number sequence, and if the period is short, or the PRNG is otherwise flawed, an advantage player may be able to 'predict' the next result. Having access to the PRNG code and seed values Ronald Dale Harris, a former slot machine programmer, discovered equations for specific gambling games like Keno that allowed him to predict what the next set of selected numbers would be based on the previous games played.

Most machines are designed to defeat this by generating numbers even when the machine is not being played, so the player cannot tell where in the sequence they are, even if he knows how the machine was programmed.

Slot machines are typically programmed to pay out as winnings 82% to 98% of the money that is wagered by players. This is known as the "theoretical payout percentage" or RTP, "return to player". The minimum theoretical payout percentage varies among jurisdictions and is typically established by law or regulation. For example, the minimum payout in Nevada is 75%, and in New Jersey, 83%. The winning patterns on slot machines - the amounts they pay and the frequencies of those payouts - are carefully selected to yield a certain fraction of the money played to the "house" (the operator of the slot machine), while returning the rest to the players during play. Suppose that a certain slot machine costs $1 per spin. It can be calculated that over a sufficiently long period, such as 1,000,000 spins, that the machine will return an average of $950,000 to its players, who have inserted $1,000,000 during that time. In this (simplified) example, the slot machine is said to pay out 95%. The operator keeps the remaining $50,000. Within some EGM development organizations this concept is referred to simply as "par". "Par" also manifests itself to gamblers as promotional techniques: "Our 'Loose Slots' have a 93% payback! Play now!" It is worth noting that the "Loose Slots" actually may describe a very few anonymous machines in a particular bank of EGMs.

A progressive jackpot is a jackpot (highest payoff) for a gaming machine (usually a slot machine or video poker machine) where the value of the jackpot increases a small amount for every game played. Normally multiple machines are “linked” together to form one large progressive jackpot that grows more quickly because multiple players are contributing to the jackpot at the same time.

Many American casinos offer free memberships in "slot clubs," which return a fraction of the amount of money that is bet in the form of comps (complimentary food, drinks, hotel rooms, or merchandise), or sometimes as cash or a promise to pay cash at a later date. These clubs require that players use cards that are inserted into the slot machines, to allow the casinos to track the players' "action" (how much each player bets and for how long), which is often used to establish levels of play that may make players eligible for additional comps. Comps or "cash back" from these clubs can make significant differences in the maximum theoretical returns when playing over long periods.
