As these prizes grow, so too does speculation about when the next winner will emerge. Many people believe that the larger the accumulated amount, the closer the prize is to being awarded. However, this is just one of the myths that surround the world of casinos.
Much like NZ pokies at Christchurch Casino, the way these machines operate is governed by a series of mathematical principles that ensure previous results have no bearing on future ones.
The difference between fixed and progressive jackpots
Jackpots tend to be among the biggest draws at casinos, whether land-based or online. This is, of course, due to the substantial prizes they tend to offer.
While online progressive jackpots tend to accumulate more and more as players place bets, fixed jackpots tend to provide the same prize every time, regardless of the number of players or the volume of bets placed.
The ways in which a jackpot can be activated, regardless of its type, vary from slot to slot. Even so, there are three common methods. The most popular is through a combination of symbols, though jackpots can also be awarded through bonus features or even random triggers.
Symbol combination activation
In many slots, the jackpot is triggered when a specific combination of symbols appears on the paylines or in positions predetermined by the game. These combinations usually involve the machine's rarest and most valuable symbols.
Bonus feature activation
Jackpot activation through bonus features is generally found in more modern slot games. In these cases, the result of the main spin alone is not enough. To win the jackpot, the player must successfully complete a special bonus round, depending on the additional mechanics built into the game.
Random trigger activation
No specific symbol combinations and no bonus round challenges. Many slots allow jackpots to be awarded through random triggers instead. However, these features must still follow the rules and probabilities programmed into the game.
Why the odds stay the same
There are several mechanisms that keep the odds the same, whether for a fixed or a progressive jackpot. Let us look into them in more detail below.
The game’s mathematical structure
A slot's mathematical structure is defined long before it is released. During the game's development, the provider determines the distribution of symbols, the probabilities associated with each possible outcome, and the conditions required to award prizes.
Common, lower-value symbols generally appear more frequently, while rarer symbols with higher rewards occupy a much smaller portion of the game's overall structure. This distribution is one of the reasons why high-value combinations, including jackpots, are exceptionally rare.
Settings such as these also influence characteristics like RTP and volatility, which many players consider when assessing how frequently a game is likely to pay over time. However, they do not change the probability of a specific jackpot being triggered on any individual spin.
The Random Number Generator as a Fundamental Tool
The RNG is the software responsible for determining the result of each spin on a slot. As the name suggests, this system continuously generates random numbers.
When these values are matched to the positions of the symbols, they determine the combination shown to the player. This ensures that every outcome occurs in a completely unpredictable way.
An example of how it works within the game’s structure
Imagine a prize draw carried out using a container filled with balls. Inside it are different balls, each representing different values and probabilities of being selected.
The entire structure has already been created by the organiser of the draw, who, in this analogy, represents the slot provider.
The hand that picks a ball from the container can be compared to the RNG. It does not select a specific combination or follow a predictable sequence. It simply makes a random selection within the conditions that have already been established.
Why previous results have no influence
Unlike a football match, where several factors can influence performance and consequently the final result, the logic here is completely different. If a coin is tossed five times and lands on the same side each time, this does not mean the sixth toss is any more likely to produce the same result or the opposite one.
There is no influence whatsoever, despite the apparent coincidence. The same principle applies to the RNG in slots, since the result of every new spin is determined by an independent random event.
