A random number generator is a vital component of a slot machine. It assigns a unique combination of numbers to each stop on the reels, and every time the slot receives a signal — anything from a button being pressed to a handle being pulled — it sets one of those numbers. Between signals, the random number generator continues to operate at a pace of dozens of combinations per second. The odds of hitting a particular combination are so overwhelming that even the most diligent slot player would be hard-pressed to hit multiple jackpots in a row.

Another important aspect of a slot machine is the pay table, which is the list of possible payouts based on the symbols that appear in the slots. In addition to listing the symbols, the pay table typically also shows how many coins can be won for each symbol and how much each combination pays. Some slots have different payouts based on the volatility of the game, which is an indication of how often the slot will produce winning combinations and how large the wins will be.
