Are All Slot RTPs Fixed in 2025?

For any newcomer to the iGaming scene, one of the first things you’re told to do before playing a slot is check out the RTP. This is the ‘Return to Player’ percentage which indicates how much of the money wagered on a slot machine is expected to be paid back to players over time. 

For instance, if a slot has an RTP of 96%, that means, on average, for every $100 wagered, the game will return $96 to players as winnings. Understanding that is crucial to understand whether a game is fair, and whether there is any potential profitability that makes it truly worth playing. The issue is that a lot of players in 2025 assume that all RTPs are fixed, and this can be an issue if you want to find a good, reputable online casino that has the players’ best interests in mind.

RTP Variations

So what do we mean when we say ‘fixed’? Well, some casinos have fixed RTP values, meaning the Return to Player percentage is set by the game provider and remains constant no matter how you play the slot, or where the slot is hosted. Others, however, allow individual operators to adjust the RTP within a specific range. 

A slot like Big Bass Bonanza, for example, is one of the most popular in the iGaming scene. It was created by Reel Kingdom, but the game provider allows the casino itself to set the RTP anywhere between 90% and 96% depending on their preferences. This means you could be playing the exact same game at two different online casinos, but your chances of winning over time might differ significantly. 

Why This Matters

In many ways, this flexibility is a good thing. For one, it allows casinos to tailor their game offerings to suit different players and market demands. Let’s say, for example, a casino is looking to attract casual players and provide a more generous playing experience. To do this, they might set higher RTPs and encourage far longer play sessions and satisfaction. Secondly, it also gives players the opportunity to shop around and find casinos offering the best value, which encourages healthy business competition among operators.

But the flexibility can be a double-edged sword. Some casinos, for instance, might lower the RTP to increase their profit margins, which ultimately works against the player if they haven’t realised the RTP is lower in the first place. To avoid this, it’s up to the players to check not just the RTP listed on the game, but also the RTP actually offered by the casino they’re playing at. All the reputable online casinos know that transparency is key to good business, so they should be displaying the exact RTP clearly in their terms or game information sections. If you don’t see it, there’s a chance that particular casino might be less than transparent with their payout rates – which can be a major red flag when it comes to their overall reliability.

Being proactive when checking RTP details, however, will ensure that you get a fair deal and can be confident that the casino itself has your interests at heart. And that’s the most important thing when it comes to a seamless, stress-free gaming experience.
