Calculating online slot probabilities

Just like almost all other forms of gambling, probability has vast amounts of importance and could be the deciding factor on whether or not players will either losing their money or land a huge win whilst playing slots. Plus, aside from a couple of specific betting strategies, you will find that when it comes to slots at, there isn’t really much you can do to influence the probabilities of winning slots, therefore it’s very important that players can calculate online slot probabilities so they can choose their slot game wisely to give them the best chance of winning!  

RTP (Return To Player) 

Arguably the most important factors in calculating online slot probabilities is the RTP (return to player percentage) of the slot game. The RTP is extremely handy and is displayed on slot games to help players understand the game they are about to place their bets on. Don’t get too bogged down by the terminology – it’s quite simple! Essentially, the RTP is an indicative percentage of the average amount players should expect to get from their bets over a prolonged period of time. Therefore, the RTP is a very handy tool when it comes to figuring out online slot probabilities. 

Another brilliant thing about the RTP is that it offers transparency to players as gambling regulations ensure that all online casinos are required to clearly display the RTP percentage. To give you an idea, most slots on average around the 96% mark and anything over that is a great RTP so you should most definitely give slots with a high RTP a spin!  

The volatility of slot games  

Another tool used to ascertain online slot probabilities is the volatility of the slot game you’re considering placing your bets on. You may have heard this phrase as it is commonly used in the stock markets, but it’s also a term which can be applied to slots. In a nutshell, different slots have different volatility, low volatility meaning it is quite difficult to win large amounts of money from a single bet, however, you’re also unlikely to lose large amounts of money quickly, either – so they have a plus side! However, high volatility means players c an expect huge jackpots, however, there is an increased risk of losing large amounts of money, too. pay out some massive prizes, but it also comes with a higher probability of losing a lot of money too. 

For example, progressive jackpot slots are extremely exciting to play and are loved by players as they get a huge kick out of playing for life-changing jackpots. Some of the prizes can even turn players into multi-millionaires from just one win! However, progressive slot games are an example of a high volatility slot game and whilst there is a chance to win big, players also take the risk of losing larger amounts of money than if they played on a low volatility slot.  

Essentially, you’re more likely to win with a low volatility slot game as they will give you more frequent wins, although the prizes will be smaller and vice versa for a high volatility slot – so choose wisely!
