Playing online gaming comes with so many choices it can be mind blowing, like what theme you prefer, mobile or desktop, which welcome bonuses are available, does the site offer the games you’re after and what banking method suits you best. Many of us don’t consider the one element which will affect our overall chance of winning and that is RTP or ‘Return to Player’. Each casino, slot or sports betting site will have an RTP, but to help you understand it all a little better we will dive into what RTP is and the highest RTP slots online. By the end of our guide, you will have the knowledge and expertise to pick a great game with the highest RTP percentage slots.

Finding Best Slots with Highest RTP

No matter which casino or new slot site you pick you will find a huge library of games. Some will take you to the Egyptian lands of Cleopatra, some to find pots of gold with leprechauns, or even battling blood sucking vampires; the variety of themes is endless. General categories tend to be video slots, classic arcade slots and pub style slot games.

But when it comes to what is a high RTP slots UK, then we would consider that to be anything 98% or above. If you see a slot game with a 94% RTP then that would be considered a low value for the player. There are games which have variable RTP so anything between 95% and 97.99% is acceptable.

We will bring you our choices from the top igaming providers such as NetEnt and Microgaming, and their slots with the highest RTP. But it would make sense that we begin by explaining what exactly RTP is.

What is RTP (Return to Player)?

highest rtp slots onlineWe’ve explained that RTP stands for Return to Player and it affects all of your online games. You will see it as a percentage and for most slot games that will be in the 90’s. This RTP amount is a rough estimate of how much you can be expected to win or lose as you play a particular game. The remaining percentage will be the house edge, or in other words their return rate. For example, Sands of Fortune offers a 93.70% RTP, which means the house edge is 6.30%.

We should prewarn you that this doesn’t mean that for every £10 you wager, you can expect £9.37 in winnings. We’ve all experienced periods of time when we haven’t won for a while, so how can that be with such a high average? This is because the calculation of RTP is done over the long term, rather than on each wager or per person. It is known as ‘theoretical’ RTP and means that a player could walk away from a £10 bet having won for example £100, or not having won a penny.

The casino and slot sites use a software technology called RNG (Random Number Generator) to establish the payout and RTP percentage. As you will gather by the name it means that the payout is completely random, so you are not guaranteed a win. This will not only add excitement to your play time, because you never truly know when you will win, but it also stops the casino from paying out more than it makes and essentially having to close its doors. There have been many sites who have closed their preverbal doors because of a big win payout and as such this is an essential safety net for us all.

It should be noted that the RNG isn’t created by the casino itself, but is established within the creation of the slot game. As such it is decided by the games provider and coded in to create the house edge we have already mentioned above. The fact that it is already hard coded in the creation of the game means it cannot be manipulated by the casino to rig the slot game however they choose. If you sat all day and night spinning the reels on one particular game, then you would have a greater idea as to how the RNG worked and what the published RTP was.

How are RTP Casino Slots Regulated?

We now know how payouts are dictated by the RNG, but before regulations got tighter this and the RTP would only have been tested before the slot games release. The introduction of the UK Gambling Commission has of course changed this and now operators must recheck the games performance on a regular basis.

This RTP monitoring ensures that there were no glitches or errors during the implementation of the slot game. Also, that there is no deterioration of the game over repeated use and time.

Which is Better High RTP Percentage Slot or High Jackpot?

Most players want to know the answer to this question and the reality is that sadly you cannot have the best of both worlds. You will either be opting for a big jackpot bonus or alternatively a slots highest RTP by simply spinning the reels.

This revolves around slot machine volatility, which has been around for a number of years but seems to be back at the forefront of igamers minds. Many casino and slot players could predict how the game was going to play and would adjust their wagering accordingly. This was due to a number of factors and was only really noticeable for people who played the game over a long period of time. This is where variance comes in, because it determines the likelihood of hitting that winning combination and the size of the jackpot. For example, slots that don’t land often, but offer large prizes are high variance games. On the opposite scale is low variance which sees a slot give small wins often.

Slot volatility and variance is something to consider when choosing the best RTP slot. Again, focusing on the jackpot, if it’s in the lower 1,000’s range, then you can expect a higher RTP. For bigger wins such as 10’s of thousands, then the RTP will be on the lower end of the scale.

When you cross both elements together you will see that high RTP slot games have both lower jackpots and variances, so you’ll be paid often but low amounts. On the other end of the scale, it’s the low RTP slot game with higher jackpots and variance, meaning bigger overall jackpots but your actual wins tend to be less often.

This is worth considering when you think about progressive jackpots, because the game will tend to have a low RTP. It’s so they can build up a pot of money before paying out the jackpot to the winning player. So make sure you factor this in when choosing the slot game you want to play. Because just focusing on the size of the potential jackpot will likely lead to you landing much smaller wins more often, than hitting a big prize.

Where is the Slot Game RTP on the Casino Site?

You have the details of how online slots with the highest RTP’s work, but how will you know what the actual RTP of your chosen game is? Most casinos don’t promote the RTP on their sites, so we have to come up with another way of getting the information we need.

Most slot games will have been written about by a blogger or review site, so all you have to do is search in Google and it should come up. For example, if you search for Blood Suckers RTP you will see that it is 98% purely from the search information and without needing to click on any of the sites.
