On the most basic level, all casino games rely on luck. Players will never know for sure what comes next, but this doesn’t mean the outcomes aren’t governed by rules.
This is because, at their core, all casino titles rely on code. Code is bound by strict sets of outcomes within a certain range, it’s just that this range can vary highly and generate many different outcomes. Such variation is owed to what is called RNG, or random number generation. When applied properly, RNG returns an unpredictable value, and it’s this value that is translated into a game’s results.
If this sounds complicated then don’t worry, it’s much easier to understand in the context of something like a slot game. In a slot game, there are many different symbols, bonuses, and jackpots that a player can win. Each of these has a different value assigned to them, and each has a different chance of landing on the reels. Since the low-paying symbols are more common, the chances of matching them are high. High-paying symbols are rarer, so the odds of collecting at least three are lower. In both cases, these landing situations are referred to as hit frequency.
Consider the following table as an example of how hit frequency works.
|Five treasure chests||2500||0.001%|
|Five golden fishes||1000||0.015%|
|Five purple fishes||400||0.05%|
|Five yellow fishes||50||0.5%|
|Five red fishes||5||7%|
With these levels of hit frequency, the total odds of achieving a winning spin are 5.356%. Since aces are the most common symbols by far, there’s a 5% chance of collecting five of them on a payline. Because diamonds are very rare, they only offer a low hit frequency of 0.001%.
Since RNG requires software, it usually operates directly in online casino games like slots. Live casino titles are usually different since most of them rely on physical systems without RNG input. Consider a live casino game such as blackjack as an example. In these games, the odds of cards appearing are derived from the combinations of the 52 cards in a deck, and how many decks are used. Essentially, the randomized outcome is the same, even if the process between software and hardware is different.
With this knowledge in mind, players are much better equipped to understand how the outcomes for games like slots are determined. Too often we believe there might be some sort of lady luck guiding us, but at its core, these titles rely on math and the hand of RNG.
