Factors That Determine a Slot’s Win Potential 

Before we start ranking our top casino slots, let’s discuss the key factors that determine a slot’s win potential: 


Short for ‘return-to-player,’ RTP refers to the amount of money each player will receive in relation to their bet. This is calculated as a percentage and helps players to judge whether a slot game is worth playing or not. For instance, the Gates of Olympus RTP is 96.50%, so players will, on average, receive €96.50 for every €100 they wager. 

The RTP of most slot games ranges between 95% and 97%. Slots with RTPs lower than 95% are generally not worth playing if your main goal is to make a profit. 


This refers to how often a player will trigger a win with a slot and what the size of the win will be. Slots can either have low, mid-low, medium, mid-high, or high volatility. High volatility means that the slot will pay out huge wins at a time. However, these payouts will be spread apart. On the other hand, low volatility means payouts will be more frequent but much smaller in size. 

Generally, players with smaller budgets will have a more enjoyable time with low volatility slots since they can extend their gameplay and enjoy a small yet steady flow of funds. Likewise, high-volatility slots are best for players who are after massive payouts. 

Max Win 

As you can probably guess, max win refers to the maximum payout you can get in relation to your bet. For instance, if a slot has a max win of 5000x, this means you can get a payout that’s 5000 times your bet. If that bet is €1, then the highest amount you can win at once is €5000. Some slots may also have a daily jackpot that will briefly increase their max win. 


Bonus features will directly influence how often a player can land a winning combination or how much they will receive through playing a slot game. Some slots grant players free spins, which allows them to play for longer without exceeding their budget. Furthermore, other games may include in-game bonus features such as cascading reels, which enable players to achieve multiple wins from a single spin.
