What does RTP mean?

RTP is an acronym for Return To Player. In its most simplistic form, the RTP of a game or slot tells us how much of the money that is put through the game will be returned to the player over its lifetime.

The important word here is ‘lifetime’. A slot with an RTP of 96% will be expected to return 96p of every 100p it takes throughout its lifetime as a real money game, not with every spin.

What this doesn’t mean is that for every £1 a player stakes they will get back 96p every single time. If this was the case we simply wouldn’t play slots because every spin would be a loser.

Slot RTP’s are based over many, many millions or billions of spins – remember a slot machine is hosted on the game providers server and thousands of people could be playing it at the same time. This is the reason you experience swings in the way a slot plays, sometimes the slot will be extremely generous and you’ll get huge wins or many bonus rounds in short succession, other times the slot could appear to be very cold – this is the game balancing out its RTP.

RTP’s are important to a player because it gives you an indication of how the slot will play – slots with low RTP’s will be more difficult to win on so you should always play where the RTP on offer is higher. Casino’s are able to set the RTP they would like a game to play at so remember, even if you play the same game at 2 different casinos, the RTP will probably be different.

Typical slot RTP’s are around the 95% – 97% mark, anything higher than this is considered an excellent RTP, anything lower may be considered a low RTP. Jackpot slots can have very low RTP’s because the slot is compensating a percentage of your stake to the jackpot – Mega Moolah for example has a very low RTP of 88.12%.

To find a slots RTP you would usually look inside the Game Info when the slot has loaded, legally the RTP has to be made available to the player.

With better graphics, interactive bonus games and innovative designs, casino slots are getting more and more advanced. Game providers are all competing to provide us with the ultimate entertainment. Beneath the amusing and charming exterior, we do however find the same old mechanics that ensures that the house always has an edge on us. In spite of this, we still love taking our favourite slots for a few lucky spins, hoping to hit that big win.

In the following article we will take a closer look at the mechanics behind casino slots, why we’re losing on them, how we can improve our chances of winning by looking at casino rtp and also why we love to play so much.

The basics – Casino RTP Slots are all about chance (RNG)

Slots have no memory. They never know how much you have won or lost and therefore this will never affect the outcome of a game round. Every spin is unique and the outcome is always randomly decided, which is guaranteed by a random number generator (RNG) being used in the slots.

To give a very simple example of this, you could picture rolling a die. The chance of hitting either one of the six numbers on this die is 1/6 every time you’re rolling it, no matter what it has previously shown. Slots work in a similar way, but where every number is a combination of different symbols and every time you press the spin button, it’s not a die of six numbers rolling, but a die that has thousands of numbers and thousands of different outcomes.

Another slight difference is that the probability for each outcome on a slot machine is not the same to one another. There’s something called hit frequency, which is a value set to determine what the probability should be for a certain outcome to happen. Let’s illustrate this by going back do the die again and picturing that the number 6 represents the highest paying symbol in the slot, whereas the number 1 represents the lowest paying one. Instead of every number having a 1/6 chance of showing up, we’re reprogramming the die so that the number 6 is showing up half as often (1/12) and the number 1 twice as often (1/3). When we’re now rolling the die the outcome will still be randomly decided, but the probability of hitting the number 1 is now twice as high as 2-5 and four times higher than hitting the number 6.

We could also illustrate this by coming up with our own slot machine. Let’s call it “The Lucky Aquarium” and make things really simple by only giving this slot five different symbols; treasure chests, golden fishes, purple fishes, yellow fishes and red fishes.

Casino RTP and Hit Frequency

Combination Payout Hit Frequency
Five treasure chests 2500 0.001%
Five golden fishes 1000 0.015%
Five purple fishes 400 0.05%
Five yellow fishes 50 0.5%
Five red fishes 5 7%
Total 3955 7.566%

As you can see in the table above, this made up game has a probability (hit frequency) of 1/100,000 (0.001%) to hit a winning line of five of the highest paying symbols (treasure chests), whereas the probability of hitting any winning line of five symbols is about 1/13 (7.566%). This is an example of how it could look like in a real slot. It is however important to know that all slots have different values when it comes to payouts and hit frequency. Generally speaking, it’s fairly common that slots have about 40% probability of hitting any winning line of any symbols.

This is why we’re losing on slots

As chance is always the deciding factor it is over a certain period of time possible to make a profit playing slots. With that being said, the house will always have an edge on us, which means that the more we play, the more likely are we to lose and in the long run we’re always losing.

The reason that we’re losing is simply because the slots are programmed to give an advantage to the house. Apart from the hit frequency determining how often we’ll get a winning outcome, there’s something called “return to player” (RTP). This is a value that’s determining how much we in theory will receive back on every spin that we make.

The return to player (Casino RTP) is always lower than 100% as 100% or more would mean that the house didn’t have any edge. For online slots the casino RTP value is usually somewhere between 92-97%. Let’s say that we’re playing a slot that has a casino RTP of 95%. This means that we on average would get 95% back on every spin that we make. When we have bet a total of 100€, we would in theory have received €95 back, thus losing €5.

As chance is always the deciding factor, this will in reality rarely be the case when €100 has been bet. Instead it could very well be that you were very lucky on your first €100 and ended up with a sum of €400 or that you had a terribly bad luck which resulted in only €20 left. In the very long run, you will however on average have lost €5 for every €100 bet.

How much do casino slots pay back?

How much you’re winning and losing in the long run is all determined by the casino RTP. This value is based on the probability for every outcome and the value of those outcomes.
If we go back to the table of our made up game, we’re able to calculate and add what the casino RTP is. This is done by first calculating the RTP for every possible outcome, which is done by multiplying the probability (hit frequency) of the outcome with the value of it. To get the total casino RTP of the slot, we then simply add all of these separate RTP values together.

Casino RTP details

Combination Payout Hit Frequency Casino RTP
Five treasure chests 2500 0.001% 2,5%
Five golden fishes 1000 0.015% 15%
Five purple fishes 400 0.05% 20%
Five yellow fishes 50 0.5% 25%
Five red fishes 5 7% 35%
Total 3955 7.566% 97,5%

In our example slot the total RTP ended up with a value of 97,5%, which is quite a common value among online slots. Please do however note that this is a very simple example and that the slots we’re playing on have a lot more symbols and winning outcomes that can happen. For us to be able to calculate the online casino RTP of an online slot, we would have to know the probability of each outcome, which we never do. Luckily this is already done by the game provider and the casino RTP can always be found in the slot’s information.

Why play slots – is it possible to win?

If we’re always losing in the long run, why on earth are we then playing so much? The main reason is of course for entertainment. Playing slots isn’t really an investment for future, but neither is going to the movies or having a spa-weekend. It doesn’t have to be, because it’s incredibly amusing and give us the thrill and excitement that many of us aren’t getting in the everyday life.

As chance is always the deciding factor it is of course also possible to win really big, even though the odds speak against us. If we’re playing jackpot slots where it’s possible to win several million, our lives would not only change forever if we would win, but most likely we would actually have beaten the house and ensured a lifetime profit. Of course the chance of winning such a life changing jackpot is very small, but the chance is always there and someone will definitely win it, which is the beauty of playing jackpot slots.

Even though we can never affect a slot’s casino RTP, we are actually able to increase our chances of being profitable by taking part of good bonus offers. This is because we’re receiving money that is not our own, but which we are able to turn into profitable withdrawals if lady luck is on our side.

To summarize, slots do not only provide entertainment and a well-needed excitement in our everyday lives, but there’s always a chance to hit big wins and even win life changing amounts. It is however important to be aware of the casino RTP and that the house always has an edge on us, which will always make us lose in the long run.

Online Casino and Slot RTP Database

RTP or Return to Player gives us an indication as to how much a game is expected to give back through its lifetime – for a slot this could well be based over many millions of spins. Don’t forget to check out the entire Slots RTP Database

Casinos are able to set their own RTP for some games, within a set limit, which is why you will find the same game may have different RTP’s across different casinos.

The lower the RTP the harder a player is going to find to win – a higher RTP generally means more wins more often, however even with high RTP’s games are still prone to huge swings and long dead periods so this must be taken into account.

We have checked the RTP of some of the games hosted at all of our casinos to get an idea of how generous the games are and taken this into consideration with our ratings.
