What does RTP mean in slots?

What is a good RTP for slots? We’ve established that RTP stands for ‘Return to Player’ rate. This rate is the return on investment so to speak – high RTP slots UK have more return on investment. This usually comes in the form of a percentage or prizes that will be returned to a player depending on funds deposited during the game initially. Therefore, whenever a player puts their funds into a game with an RTP, the player expects a return. So, let’s go back to the blackboard, bring out that chalk, and look at the RTP theory:

Say, you’re playing a game with an RTP of 97%. So, when playing the best online slots RTP rating of 97%, for every £100 you put in, in theory, you will get the chance to receive £97 over time. If say, you’re playing a game that has an RTP of 50%, and you wager £100, then the return on investment would be that of £50 over time. See why we were saying that it’s best to check games that are as close to 100% as possible? That’s more chances for ka-ching!

RTP slot games work out like this: the higher the RTP, the less the casino wins with every spin. So, keeping in mind our little maths equation: if you play a game that has a 97% RTP, that means that the casino has a 3% ‘return to house’ margin or profit. Or for example, another game with a 50% RTP, would mean that both player and house have a 50/50 return margin. See why it’s important to look at RTP percentages.

Always bear in mind that of course, the probability of winning each time needs to be factored in. So, remember that the slots RTP is calculated across millions and billions of spins, as an average percentage. So you might be on a losing streak, and thus have a 0% RTP, or you might win big, and have a 200%, or even 5000% streak – it’s calculated across so many spins that it’s based on random generation. Remember, the higher the percentage, the more chance of winning, that’s why we’ve listed some of the best RTP online slots for you to check out.

How to find RTP on slots

A good question is how to find RTP on slots. Best to check the game’s info if you want to look at their RTP. The United Kingdom Gambling Commission (UKGC) has made it a requirement that gaming machines need to display the RTP % or odds. You usually find this in the slot’s paytable button (or a more info/ ‘i’ icon) which has information on the slot game in question. You can also check out PlatinPlay Online casino reviews or try and calculate it yourself if you fancy doing the maths.

RTP Vs Volatility

So, we’ve covered online slots RTP, but we should always mention volatility. What do we mean by this? You know, certain slot games RTP have a low or high volatility in how frequently they pay out. So, bear in mind that RTP and volatility work hand in hand:

High Volatility: usually, payouts from slots are big, and aren’t frequent.

Low Volatility: usually, payouts from slots are small, and are distributed evenly.

It all depends on how much you’re able to risk to get the big wins.

RTP is important because the higher the theoretical RTP, the more chances you have of getting a return on your initial investment.

RTP stands for return to player – so it’s how much funds you will get back from your initial bet.

Most definitely! The majority of slots are accessible on mobile devices, and the ones mentioned in our article can be found in top UK slot casinos.

We’ve found two highest RTP online slots: Book of 99 (Relax Gaming) and Mega Joker (NetEnt) both at 99% RTP.

Each slot game is different, but the highest RTP slots UK have bonuses, free spins, multipliers, and sometimes progressives.

Slots with the highest RTP gives players more chance of winning. It’s calculated as follows: ge the amount returned and divide it by the total stake amount, then multiply that by 100.
