What is RTP in online slots

The return to player percentage is a way for you to judge what your expected payout percentage may be with a certain casino game or slot machines. His metric will be represented as a percentage, showcasing the return on your betting stake on average over time. Naturally, some slots will have high volatility or lower volatility than the average games, but over time this will be accounted for as part of the RTP value.

If a game has an RTP of 97%, this means that for every £1,000 that you bet, you can expect a total return of £970. Naturally, in the short term, you can be profitable by playing different casino games, but if all things stay the same, the payout percentages will revert towards the RTP of a given title.

How RTP is calculated

There are a couple of different ways that the RTP of a game can be calculated. For the most part, when you are dealing with online casinos and game developers that are licensed by respected authorities and have their games independently tested on a regular basis by the likes of eCOGRA, the RTPs will be calculated for you. Oftentimes, you will be shown the RTP of a given game in the lobby of an online casino.

You can calculate the RTP of a game by looking at the total sum of money returned to the players, which is divided by how much in total was gambled by the players. More than one million spins will normally be looked at so you can hit a critical mass whereby you can get an accurate representation of the RTP of a given game.

Naturally, online casinos will want to have an edge on the games that they offer so they can profit in the long run. Therefore, the difference between the RTP of a game and 100% will be the house edge. For example, if a game has a 95% RTP, this means that the house edge will be 5%.

Slot variances

One of the biggest variables you will come across when comparing different slots is the variances of the payouts. There will be some games that will see you win something very frequently, meaning that the game has low variance.

For those games that payout bigger sums but on a more sporadic basis are labeled high variance slots, as there is a bigger gap in between wins. However, just because one game has a high variance and another has a low variance doesn’t mean that they can’t have the same RTPs.

Over the course of one million spins, they may on average payout almost the exact same sum of money to players. Casino players will often choose a game type that fits their needs. Some like having the chance to win on a regular basis, even if it is smaller sums, while others prefer to wait it out for the excitement of winning bigger returns even though they are not the best paying in the long run.

Progressive jackpot RTPs

While progressive jackpot games will have the same features and mechanics as a regular slot game, their RTPs will usually be significantly lower than your average non-progressive slot title. Mega Moolah is one of the most progressive jackpot games in the world today thanks to its massive potential big jackpot win, but it has an RTP of 88.12%.

However, the reason for the lower RTP is because a slice of every bet that you make is going towards the progressive jackpot and is not reflected in the RTP. When you take into account the jackpot features of these games, they are usually worthwhile playing despite their lower RTP values.

How to find RTP rates of slots

To find the RTP rates of slots, you can usually come across them on a given online casino. While you can do a quick internet search, even the best RTP slots can change from time to time or from operator to operator. The majority of the bigger online casinos in the world today will showcase the RTP value of a title when you see it in the game library or you click into a specific game and read its description.

Some casinos will even have a dedicated page that showcases the RTPs of every single game that is currently available on the platform. This will often be linked in the footer of the website.

Summary

As you can see, slots with the best RTP values play an important role in the online casino world. While they are not the be all and end all for choosing an online slot, the best RTP slots are certainly going to be a consideration to a lot of players.

If you want to get started playing one of the high RTP slots, you can register for an online casino account in a couple of minutes and get your hands on a great welcome bonus.

FAQs

Is the RTP of a slot the most important metric to look at?

The answer to this question depends on your preferences as an online slots player. Some people only want to have fun when they are playing these games and don’t care if the payout percentage is a little less than what is normal. Then there will be those people who will be striving to maximize their return as much as possible and only playing high RTP games.

Is there a way to be profitable by playing slot games?

As the RTPs of slot games will be less than 100%, this means that the house has an edge in the long run. However, there are some ways that a player can stack the odds in their favor. This could be through utilizing lucrative loyalty bonus programs where they earn perks or cashback over time as they play games. Using bonuses as part of your spins strategy can also boost your profit from these games, as you are playing with the house's funds.

What casino games have the best RTPs?

The RTPs will vary depending on what game type you are looking at. The likes of video poker and progressive jackpots usually have lower RTPs, while slots can often have RTPs in the 96-97% range. House games will almost always have the best RTPs, with the house edge being smaller and many of these games having RTPs in or around 99%.

How do you know if the displayed RTPs are legit?

If you can see the RTP values of different games on an internet gambling site and you are wondering if they are a true representation, then you need to look at the reputation of the platform. Most of the leading sites licensed by the UK Gambling Commission will have their games independently tested from time to time to make sure that their RTPs are as they are displayed. Therefore, if you are dealing with a legit site that has a good track record of being legit, then you can rest easy in this regard.

Are high variance or low variance slots better to play?

This entirely depends on your preferences. Some players prefer getting regular hits of wins, despite the lower payouts, while others like the excitement of waiting a longer amount of time for those big wins. You can also get a good mix of these two approaches by finding a slot that has a medium variance, so you are getting the best of both worlds.

What are some other game developers that offer high RTP slots?

As well as the likes of NetEnt, Play’n GO, NextGen Gaming, and Quickspin, some of the other developers that offer high paying slots include Microgaming, IGT, Playtech, and Barcrest.

What are the best welcome offers for an online casino?

Most online casinos will have some sort of welcome offer for new players. This could be in the form of a first deposit bonus to boost your bankroll or a selection of free spins. Some of the popular free spins games you will come across include Rainbow Riches and Starburst. Whatever the case may be, the wagering requirements of the offer will dictate how good it is in reality. As T&Cs apply, some offers look better on the surface as they do when you dig a bit deeper. Make sure that you only avail of the deposit bonus within your means and don’t deposit what you can't afford. If you do have any issues with your gambling, you can check out begambleaware.org.
