How to Understand the Probabilities in Online Slots

It is estimated that more than 70% of the iGaming industry revenue comes from online slots. These titles also tend to top the ratings of the most popular games both at fresh casinos added in New Jersey and established platforms. Today’s publication looks into the factors that determine the winning chances of each game, and explains how players can assess these probabilities.


What is Slot probability?

Slots probability is the chance of winning a spin, which calculated mathematically based on the number of symbols on the reels. Let’s look at the most common three-reel slot with 20 symbols per reel. Such a game has a 1/8000 chance of landing any particular outcome. Knowing the number of winning combinations, users can look at the mathematical odds and calculate the chance of landing any of them. However, the result would not be very informative, as each outcome may have a different payout.

How to find odds of casino software?

Players must consider the house edge to calculate the gamer’s return-to-player (RTP) value. Each title at recently-legalized Michigan gaming platforms and other online casinos has an RPT. This percentage indicated how much of wagered amount the player can get back (usually around 94–98%), while the remaining 2-6% is the house edge.

Because a random number generator is used to determine the outcome of each spin, the real returns do not always correspond to the stated value in the short term. Each reel spin has the same odds of winning or losing regardless of the previous rounds, and third-party agencies assign certificates validating the correctness of RNG. Part of the appeal comes from the unpredictable nature of slot games and the possibility of lucky streaks.

How does probability affect the gameplay?

Players must take into account all game mechanics and, armed with this information, make insightful decisions on how to play. All metrics should be looked at on a large scale to understand them fully. That goes for RTP, volatility, and statistical return percentage.

Quality games have reliable RNG that delivers random outcomes for each spin. Simultaneously, each title comes with an RTP percentage, which will be accurate over the span of millions of spins. However, and individual session can go orders of magnitude below or above the theoretical returns, depending on luck.

Volatility measures how often the slot pays out and whether those amounts are bigger or smaller. High volatility means the software will pay out less frequently, but the prizes will be more substantial. Low-variance titles pay out frequently but in lower amounts.

SRP statistics show how much a game paid out in a certain period. When gamers know all these metrics, they can better understand how online gambling software functions, and assess the odds of landing a win.

Can players devise a strategy based on chances to win in slot games?

Unlike skill games like blackjack, online slots are a true game of chance, where RNG ensures each outcome is entirely unpredictable. This means that a new gamers and a professional will have the same chances of winning. Thus, strategies should be seen as more of a way to diversify the experience, rather than a way to earn money. Still, there are some strategic considerations one can make to steer their experience in the desired direction. For instance, it usually a good idea to take advantage of the bonuses on offer.

If gambling website visitors like more frequent payouts, low-volatility titles are probably the best choice. Casual users and those with lower balances can enjoy these more. High-rollers and players chasing big wins can opt for high-volatility software. 

Mathematically, more paylines, reels, and symbols can increase the likelihood of a win. Simultaneously, users should look at the RTP and choose games with higher returns to further boost the chances of getting their wager back.


Why is probability somewhat irrelevant in online slots?

The software determines the outcome of every single spin with a random number generator, making each round entirely random.

Why is RTP important for players?

Return to player is a statistical percentage of money the game will pay out from the wagered amount, and it shows what to expect on a large scale from an online slot.
