How do online slot machines work? Random number generators explained

Online slot machines have become incredibly popular over the past few decades, providing entertainment and the chance to win big from the comfort of your home. A random number generator is a computational program or device that generates a sequence of numbers that cannot be reasonably predicted. The sequence of numbers exhibits no discernible pattern, so they appear random. These randomly generated numbers are then used to determine the outcome of the online slot spin.

Physical slot machines use the natural randomness of physics to generate unpredictable outcomes. The force used to spin physical reels combined with their starting positions when a player hits spin results in sufficiently random outcomes. Online slots have no physical reels to spin. So, they rely on RNGs to mimic the randomness of physical reels digitally. RNGs generate long strings of numbers that are then translated into slot outcomes when the player hits spin.

How do online slot RNGs work?

There are several methods RNGs use to generate their random number sequences. But the most common is the mathematical algorithm approach. RNG algorithms start by seeding an initial number called a seed value. This seed value initializes the algorithm sequence. To ensure randomness, the seed value comes from an unpredictable source like the microsecond time from the player’s computer when they hit spin.

From the seed value, the RNG algorithm generates the next number in the sequence using mathematical formulas. Subsequent numbers are determined mathematically from the previous number. Even tiny variations in the initial seed value cause significant differences in the sequence. The RNG algorithm runs through trillions of number combinations per second, outpacing a player’s ability to predict the values. The result is a sufficiently random sequence for all intents and purposes.

Mapping random numbers to slot outcomes

The raw random number sequence from the RNG isn’t usable yet for slots. The numbers first need to be mapped to correspond with the possible outcomes of the game. For physical reel slots, this mapping is straightforward. Each symbol has several stops on the reel it occupies. If there are 200 stops on a reel and a Wild symbol takes up 20 of them, the RNG simply needs to generate a number between 1 and 200 to determine which stop lands on the pay line.

Why RNGs are essential to online slots?

RNGs are a critical component enabling online slots to match the experience of physical slot machines. Without RNGs producing unpredictable outcomes, online slots would be predictable and unplayable.

  • Fairness – RNGs ensure all outcomes are truly random and unbiased. Players have the same odds to win on every spin.
  • Unpredictability – The RNG sequences have no patterns and are impervious to prediction. Players cannot foresee the next outcome.
  • Variety – Billions of RNG permutations allow for tremendous game variety compared to limited physical reels.
  • Speed – RNGs allow instantaneous outcome generation to accommodate faster game speeds.
  • Security – Encrypted RNGs and seeds prevent tampering with game outcomes on the backend.

While you can’t physically see or hear the reels spinning, RNGs enable online slots to provide the same enticing experience and rush as their physical counterparts. You spin, win, and have fun knowing the games are fair and randomized just as if you pulled a lever or pushed a button in a real casino.
