RTP Explained

The Return-to-Player ratio, or RTP as it’s more commonly known, is the proportion of wagers a slot title will pay out over an infinite lifetime. The RTP value of a slot is expressed as a percentage, so if a game has an RTP of 97% then, in theory, for every €1 wagered on the game it will pay out 97c.

Generally speaking, the RTP is widely accepted as a good indicator as to how a slot will perform, but it is only an average and it holds no intrinsic value. As such, players should not view a high RTP as an indicator of an expected return.

As a slot’s RTP is calculated over a minimum of at least one million spins, the average will not be accurately reflected during a typical game session and will not influence your chances of making any significant wins.

Slot Variance/Volatility Explained

High payout slots may sound like a decent opportunity to take home some impressive winnings, but it’s a little more complicated than that. The RTP percentage is calculated using an infinite number of bets, meaning that the RTP won’t necessarily be reflected by a typical play session.

In fact, the better indicator of how a slot will behave during a session is its variance, or volatility. Low variance slot games generally pay out small amounts at a relatively high frequency. High variance games, on the other hand, are those that pay out less regularly, but when they do the value of the jackpot is usually higher than what you might come to expect from a low variance slot.

Progressive jackpot games are the most common example of a high variance slot, giving players the opportunity to land a truly life-changing amount of cash if they’re lucky enough to bag the grand prize.

You can also come across medium volatility slots which pay out more frequently than high variance slots and with slightly greater values than low variance slots.

Progressive Jackpots

Progressive jackpots are one of the most exciting slot variations out there, largely owing to the enormous cash prizes available. These types of jackpots increase every time the slot is played, building to a potentially huge prize pot, before paying out at very sparing frequencies.

Players can contribute to the jackpot with optional side bets, or the slot in question may use a fraction of each stake. What’s more, progressive jackpots don’t have to be tied to single games, meaning stakes from multiple slots can all be fed into a singular progressive jackpot. As progressive jackpot games are as high variance as they come, however, there is an extremely low chance of landing a payout.

Best Payout Mobile Slots

Slots are a staple of the online casino experience, and you can now take the thrill of your favourite high payout slot wherever you are in the world via your smartphone. Mobile gambling has developed at a lightning pace in recent years, with users of both Android and iOS devices able to make the most of the spinning reels anytime, anywhere.

Game software developers have utilised the latest developments in gaming technology, such as HTML5, to not only improve the speed of your chosen title but make the entire experience as immersive as possible.

For the best mobile slots experience, your best option is to download a native casino app. These not only offer the smoothest possible gaming experience but push notifications mean you’ll never miss out on the latest bonus.

Generally speaking, native apps can offer you quicker processing speeds than mobile optimised sites, but this will depend on the handset itself rather than the app, and can also be affected by whether the app has been fully optimised for your chosen handset and operating system.

Slot Bonuses

Bonuses are a huge part of online gambling and it’s no different when it comes to the best payout slot titles. Whether you’re playing on a low variance game and picking up lots of regular, small payouts, or you’re biding your time with big one-off payouts on a high variance title, a good bonus can set you off on the right foot.

Matched Deposits

This bonus involves the casino you sign up to matching your first deposit up to a certain amount, such as 200% up to €200. In this instance, the bonus will more than double the amount of cash you first brought to a site. You’ll have to bear in mind that wagering requirements will need to be met in order to make withdrawals.

These are important to be aware of, especially if you’re looking to take home some big payouts from a small number of wagers.

Free Spins

Free spins are the perfect bonus for slot fans as the spinning reels are exactly what these promotions have been designed for. You can get your hands on a select number of free spins either as part of a welcome bonus bundle or as part of a loyalty bonus, meaning that there are plenty of chances to have fun on your favourite slot titles without having to pay a thing.

Slots themselves will often dish out free spins as prizes for winning combinations or success in the bonus rounds. As with all bonuses, however, there will likely be wagering requirements that need to be fulfilled, so make sure you know what they entail before you sign up.

Unlike matched deposit bonuses, the wagering requirements placed on free spins are tied to the amount you win with those free spins rather than the monetary value of the bonus.

Bonus Calculator

Easily find out the amount you’ll need to wager to meet your bonus’s wagering requirements with this calculator. Fill in the deposit value and percentage, the wagering requirements, your favourite game’s contribution percentage, and whether or not your casino includes your qualifying deposit in the calculation. These details can be found in your casino’s bonus terms and conditions. Once you click ‘calculate’, your wagering requirements will be worked out instantly.

No Deposit Bonus

No deposit bonuses are just as exciting as they sound, giving you the opportunity to claim some bonus funds without paying a thing. A no deposit bonus is great for slot players looking to get to grips with a new title or site without risking any of their own money.

But, while no deposit funds need to be paid, these bonus types will likely have high wagering requirements or other terms and conditions that will need to be satisfied before any winnings can be claimed.

How to Stay Safe

The best payout slots promise some of the most exciting gambling experiences for players, but that doesn’t mean that there’s an absence of risk. As such, there are a couple of things we would recommend to help you to stay as safe as possible when you play online.

Don’t Spend More than You Can Afford to Lose

High payout slots may appear to be an exciting way to take home some solid winnings over other titles, but high RTP rates are simply an average garnered over millions of hours of gameplay that serve as an indicator to how a game might play out. You should therefore be wary of how much you spend on a particular slot site and make sure that you don’t chase any losses in the hope of an eventual big payout.

Set Your Limits

Nowadays, online casinos allow you to set up both time limits and deposit limits on your account. This means that if you feel like you’re spending too much time on a particular site or spending more than you’d like, you can set up restrictions that stop you from going beyond your limits.

Self Exclusion

If your time at an online casino has progressed beyond a casual pastime and has become a very real issue in your life, then you might want to consider signing up to a self-exclusion programme, such as GAMSTOP. By joining such schemes, you’re able to impose a ban on yourself from accessing any licensed gambling sites, and you can set this to span any length of time that you need, from six months all the way up to five years.

Gambling Help

Gamblers Anonymous — Gamblers Anonymous has been at the forefront of protecting vulnerable individuals from problem gambling for decades. Those struggling with compulsive gambling habits can attend group sessions where they can discuss their experiences with other individuals who are struggling with similar issues.

The Gambling Awareness Trust — The Gambling Awareness Trust is an independent charity that works to support those struggling with problematic gambling habits by raising money for research into the issue. They also help gather funds to provide better standards of education on the issue and care for those dealing with its worst effects.

GambleAware — GambleAware is one of the most well-known gambling charities working today. The organisation provides a great range of care and support for those struggling with compulsive gambling habits, as well as offering an enormous resource of information for those who need it.

Medical Advice –– Gambling addiction is a recognised medical condition, and your doctor will be able to provide advice, support, and treatment for diagnosed sufferers. If you have any concerns about your gambling habits and how they are impacting your life, an appointment with your doctor is a great first step on the road to recovery.

Ready to Play the Best Payout Slots?

That’s all there is to it! If you’re looking for your new favourite high payout slot, then keeping an eye out for the RTP of that title is a strong indicator that the game is fair. A better indicator of how it will perform is the volatility of that slot, however, which can give you a clearer idea as to the frequency and size of potential payouts.

Remember that a large RTP is no guarantee of regular payouts, while high volatility does not mean that you can expect to win a huge jackpot any time soon –– ultimately, slots are always a game of chance. There is still a lot of fun to be had when playing these slots, however, and our rankings and reviews make it easy to find the right slots site for you.

Compare, sign up, claim your welcome bonus, and start playing at your favourite high payout slots.

Frequently Asked Questions

  • Your best option for withdrawing your funds quickly is by using an e-wallet like PayPal, Skrill, or EcoPayz. These payment methods allow you to not only deposit your cash in no time at all, but there is also the potential to withdraw it from your casino account in the space of just a few hours at certain sites. Withdrawal times are casino-dependent, with some operators having long internal processing times. In most cases, however, the longest wait you are likely to come across is 48 hours, which is a marked improvement compared to the 5 working days you can often expect when withdrawing with a debit card.

  • Sadly, high payouts do not guarantee you a win. While low variance slots may give you more regular payouts and high variance ones far greater jackpots, there is no definite win on the cards when you do play at a high payout slot. What’s more, the RTP of a slot is worked out using an infinite number of different sessions, meaning that it is only truly accurate if you make an infinite number of bets.

  • Absolutely. Playing your favourite high payout slots on your mobile is now easier than ever before, with native apps being the best option for an immersive handheld experience. Not every site will offer a native app, but all of the online casinos we’ve recommended here do at least have a fully-optimised mobile site that you can use to play via your iOS or Android device.

  • There is no single software developer that stands head and shoulders above the rest when it comes to progressive jackpots, with each top software house making games that appeal to varying customer tastes. We here at TopRatedCasinos recommend playing progressive slot games from high-quality software developers such as Playtech, Microgaming, and NetEnt. These organisations have been around for some time now and you can use that experience as an assurance of high quality when it comes to the progressive slot titles on offer.

  • Slots are the only games that have a stated payout rate, but there are other games out there that are equally as rewarding. There are a range of blackjack and poker variances that have low house edges, which is a factor that works in a similar way to a high RTP. A lot of different games will also have progressive jackpots attached to them, meaning that there’s the chance to land some big wins on a selection of your other favourite casino games.
