This is normally represented as a percentage, yet if you don't fully understand what the numbers mean then today's your lucky day!

More than that, we'll tell how RTP percentage affects gameplay and how you can make sure that you're getting the most from the slots you play.

What Is High RTP Slots?

One of the most frequent questions we get is what is a slot RTP. The answer requires more than one sentence. Best RTP slots (return to player) or similar terms can mean several things and there's no single RTP slots definition. What does RTP stand for in gaming at casinos specifically, though? Simply put, it represents the rate at which you'll receive your money back… sort of.

High RTP slots is the percentage of total wins, over the total stakes played. This equally applies to everything from old RTP casino games to the new and best RTP online slots. However, it's theoretical. This means that what you win at slots is calculated over a extended period of play, and doesn't represent what happens each time the game is played. For example, if a slot has a 95% RTP, 5p loss and 95p win isn't what you should expect on average per £1 you wager.

This is because sometimes, your 95p could be going towards somebody else's win, or somebody else's stake could be contributing to the £50 you've just cashed in. Each RTP game has a payout that's not evenly distributed. If it was, we'd be paying 5p to play rather than gambling. Besides, if the RTP in gaming was fixed to each spin, who would even play knowing they were losing out?

How To Calculate Return to Player?

The beauty of gambling is in the uncertainty; the idea that for your £1, you could be taking five other players' 95ps and winning £4.75. An RTP is a measure of all the games played by all players, pooled together. So, for example, if you take home £250 from a £10 session, you' can calculate RTP at 2500%, yet this means that many other players probably have experienced an RTP lower than the advertised percentage to cover for your better RTP.

In various return to player percentage pictures, you may see that even good slots yield different returns on every single turn. In theory, this should equal the official RTP player is sometimes provided with. More often than not, though, no such info is given. You can be sure that even highest RTP slots return less than 100%, even if a game claims most sure wins potential.

Other than that, slot RTP calculation isn't just tricky, but practically impossible. You may take a calculated guess by keeping track of your bets and winning at the slots, but it's only going be an approximation. That's because the theoretical payout may not be realised in any particular number of spins and you can't take into account the spins other people have made beforehand.

So, Why Should You Pay Attention To A Game's RTP?

Reading above, you may be tempted to think that if a game's RTP isn't even representing your gameplay, then why consider it at all?

Well, if you look at the flipside of an RTP, it shows the ‘house edge'. Every mobile casino has a house advantage or house edge explained as their profit on each game, even if the game is called a sure win slot. Naturally, casinos wouldn't be able to stick around if they didn't make a little something from RTP gaming.

House Edge Slot Machines

House edge is the exact opposite of the RTP. So, for example, if a slot offers a 96% RTP, this means it also has a 4% house edge. It's the percent you'll theoretically lose to the house.

These figures are useful if you want to see if you're playing high payout slots and want to find the highest RTP slot. Whilst either of these numbers won't predict what happens in the short term (as you probably know, anything can happen in the short term), they do predict the long term results of the game and ultimately, show how much of a sure win casino you're gambling at.

A sure win mobile slot should offer no less than a 94% RTP. Any slot under this amount is probably just a money grabber, yet in recent years we've also seen the rise of slots which alter their RTP based around how long you play. These kind of slots are the type that may offer ‘levels' as a feature. The more you play, the higher level you reach in the game, the higher the RTP rises. If you play long sessions, these are the best slots to win on.

Is A High RTP Always A Good Thing?

It would seem fairly obvious then, that as a slots player you should always choose slots with a highest RTP and a low house edge. However, this isn't always the case as sometimes players need to consider the slot's volatility (or variance) too. Volatility refers to the risk slots inherently possess. Broadly speaking, low volatility slots will pay out frequent small amounts, whilst high volatility slots will pay out large sums once in a while.

High Volatility

High volatility slots will often have a lower RTP (or a higher house edge), but this isn't to say there's no good to go slot with a high variance. On the contrary, that's what slots win the most as they offer much bigger wins than regular games and top RTP slots. However, you also run the risk of spinning for quite a while without any substantial rewards on these games.

This is because your 95p (if we consider the example used above) is being stored up by the slot to create one huge payout. As mentioned earlier, you have no way of knowing if you'll receive the money or another player will. This considered, it's generally ok for these slots to have a lower RTP; highly volatile slots often offer an RTP of around 94% but some games can go as low as 92%.

Low Volatility

On the other hand, low volatility slots are among the highest win rate casino games and will boast a higher RTP for most sure win potential. However, as you can probably guess by now, better stakes also mean lower payouts. Low volatility win slots pay out frequently, which makes them perfect for casual gamers or those who want their budget to last longer.

The RTP of these slots is higher as they're not pooling the money so often. Using the same example as earlier, this means that it's less likely that your money will go to somewhere else.

How To Win At Slots With Different RTP?

To figure out how to win on slots the next time you’re at a casino, simply remember the types of variance in slots. A good gameplay is when online slots wagers and RTP correlate, which is easy when you know how to do this the right way (see below).

There is no best time to win at slots online, but there’s always the advantage of knowing the game’s RTP. If it’s low, the game isn’t very lucrative unless it has a high variance. Such games are like high risk casino offers. They’ll either pay you tenfold or leave you barehanded. So you should be ready to lose it all and lose it quickly. And if you win, don’t rush to put it all at stake again.

The best slots RTP likely means that the game has low variance, as we mentioned already. How to play the slots and win when they pay in such small sums? Easy – wait for the bonus rounds. It’s easy to do it with small budgets due to frequent returns, but don’t get carried away either. Asking how much will my bet return after every couple dozen spins is a good way to keep the bankroll in check.

Winning at Casino Slots with Progressive Jackpots

Progressive jackpots are a whole different issue. While they usually belong to the high volatility slot class, they also offer jackpots that significantly lower the game’s RTP.

Is there a way to win at slots with such jackpots aside from actually hitting the grand prize? We’d say yes, but your chances are better on other games. Jackpot slots are aimed at players who risk whatever to win it all. They’re the lotteries of slots. If you want to learn how to play slots at casino and win often, jackpot games aren’t the best pick, because you’ll either win once or not win much at all.

Knowledge about RTP betting wouldn't be useful without actual sites and casino games to use RTP play strategies at. Unfortunately, many providers are hiding the theoretical payout of their slots because this would give an advantage to an informed player. For example, on most NetEnt slots RTP is nowhere to be seen. Only by an extensive research you might learn that Wild Wild West slot RTP is 96.75%, which is actually not far from the best slots payout percentage from NetEnt.

It's the same reason why online slots RTP list is something that you won't come by easily. Luckily, we have a solution for you. You can find many high and low RTP slots at GoWin casino, under the various ‘win' categories in the game search. Otherwise, you may try:

1. Casino table games

That's right. Casino table RTP games often have high returns around or even above 99%. Of course, you won't win much in a single round, but they're the best casino games to win steadily and maximise your returns.

2. 1429 Uncharted Seas slot

This slot has a ridiculously high RTP, which is 98.60%. Unfortunately, this is the reason why it's always excluded from all online casino bonuses. On the bright side, you won't find a slot that pays as much and as often as this one, at least in theory. Therefore, it's arguably the best slot game to win money on.

3. High Rise slot

Boasting of a 95.14% RTP, this is a game by Realistic that pays out big without eating up all of your funds in no time. As the name suggest, it offers some high jackpots, so don't let the classic layout turn you off.

4. Mega Moolah slot

The world's most popular progressive jackpot slot is played by thousands every day and it's been there for many years already. You'll be surprised to learn that its RTP is only 88.12%, which seems low, but is usual for the best high variance slots. If you want higher Microgaming RTP slots, try something like Your Lucky Day.

5. Your Lucky Day slot

With an RTP of 96.4%, this underrated Microgaming slot features several bonuses, each more lucrative than the other, promising huge returns for the players on the lucky end of the game's payout mechanism.

6. Mega Joker slot

Coming back to NetEnt RTP slots, this one here is the very best RTP slot you will ever find. Not to be confused with the Novomatic's game of the same name, Mega Joker by NetEnt offers up to 99% return to player (might be lower at some casinos though). It's an old classic type of a slot, but it easily beats all other best payout slots.

7. 1 Can 2 Can slot

Of all Can Can slots and slot machines, this game is the most popular and not without a reason. It has free spins, wilds, frequent bonuses and they have good payout rates, even if the slot itself isn't as impressive with 95.25% RTP. But nothing would be impressive after Mega Joker.

You can find games included in these examples and similar slots at GoWin, Casumo, Power Spins, Youwin casino and many other RTP online casino sites. These sites have a good casino win rate and if you're looking which casino pays out the most to you, these are all good locations to start.



So, what does RTP mean in gambling? There's more than one answer to the question. It affects the theoretical payout size, the house profit and the likelihood of a casino bonus for the game (best RTP slots UK rarely get bonuses when they already have more than 97% RTP).

It's important to consider both a slot's RTP and its volatility. First and foremost, you need to decide what you want from your game. You know whats RTP in slots, so you can choose low variance slots with high RTPs if you want your session to last longer, and you're happy with walking away only a little bit more than what you started with. Conversely, if you want to take bigger risks and test your luck at winning the jackpot, then high volatility games are what you should be playing, and the RTP of the game becomes less important.

Now that you know what's RTP, how to play the slots how to win them and what to expect from them based on this statistic, the knowledge of RTP gambling will help you immensely at maximising your wins over time.
