For experienced slots players, one of the most important pieces of information about a casino game is its RTP. The Return to Player value can help players to gauge, roughly, how much they can expect to lose when playing a particular title.

Need a refresher? No problem. Think of RTP as a sort of ‘reverse’ House Edge. Let’s take that favourite slot, Starburst, as an example. NetEnt tells us that the RTP for Starburst is 96.1%. If we apply our previous analogy, that means the ‘house edge’ would be 3.9%. Theoretically, that means that players will get back 96.1% of what they wager.

Of course, this doesn’t mean that for every £100 wagered on Starburst a player will necessarily win back £96.10. That’s where that word ‘theoretically’ comes in. If there was such certainty, there’s no real point to gambling at all is there?

RTP is calculated over the long-term, not per wager.

RTP is calculated over the long-term, not per wager. So a player could walk away with an £80 win on a £10 wager or with a completely empty bankroll. Slot games are completely random, thanks to their RNG technology, but the Return to Player value gives a helpful indication.

So what are high RTP slots? Well, that’s kind of an arbitrary thing and it varies depending on who you ask. At JohnSlots, we think that:

• A high RTP is anything at or above 98%
• A mid-range or average RTP is anything that falls between 95% and 97.99%
• RTP values below 94.99% would be considered low

A similar release to Mega Joker with a twist is Yggdrasil’s Jokerizer. Coming right up with a tempting RTP range, it offers an optimal 98% payback.

Jokerizer lies upon a sparkling 5-reel grid with 10 both-way paylines. In other words, winning odds are multiplied by aligning matching symbols from left to right and right to left.

#6 Secrets Of Atlantis Slot – Play At Bally Casino

Rounding out the top half of the 12 slots with the highest RTP is Secrets of Atlantis. One of the highest RTP slots around at 97.07%, it’s no secret that this is one of the more popular online slots, and you can play it now at Bally Casino.

Five reels. Four rows. Forty (fixed) paylines. This great underwater adventure includes “Colossal respins”, nudge wilds, “both way wins” and a bonus feature.

20. Dazzle Me by NetEnt RTP: 96.9%

Dazzle Me is a simple slot game which takes its inspiration from classic slot machines and reminds us of the old Bejewelled video game. The RTP here is pretty high and this NetEnt slot includes features such as Wilds, Scatters and of course, Free Spins.

NetEnt continue to develop fun and interesting games and Dazzle Me certainly falls under this category.

Jackpots and Progressive Jackpots - the Highest Paying Slot Machines

Jackpot and progressive jackpot slots are very popular, as players can win massive amounts of money if they are lucky enough. But are these really the highest-paying online slot machines? Let’s see how they work and how they stack against regular slots when it comes to RTP.

Jackpot and Progressive Jackpot slot machines work the same way - any player can randomly win the huge jackpot on any spin, regardless of their bet. The only difference is that for the former, the jackpot amount is fixed, while the latter comes with a jackpot that increases as players make bets.

Once a lucky player wins, the amount resets and the counting starts again. Therefore, some players may win a huge amount while others will get a lot less.

If you want to test out how to claim those huge amounts, try out our wide collection of free casino slot games and enjoy the immersive experience.

Both types of slots can have up to four jackpots, so your chances of getting your hands on one are even higher. Mega Moolah by Microgaming is a perfect example of such game. It comes with four progressive jackpots, from Mini to Mega, special symbols, and features such as Free Spins and Jackpot Bonus Game.

BE AWARE!

Progressive jackpot slots usually have lower RTPs than regular slots.

Many players think that progressive slots are high-paying ones, with payouts better than the regular ones. This is, however, a beginner’s mistake, as the RTP is usually lower for these games. Regardless, players like the idea of a huge win, but since this is awarded randomly, some players end up losing their funds without hitting the big win.

This being said, a regular slot machine with a higher RTP could pay out better over a longer period of time.

#12 Serengeti Kings Slot – Play At BetMGM

Even though Serengeti Kings comes in with a 96.2% RTP, it is still one of the highest RTP slots games at BetMGM (and other online casinos). It may be last on this list but it is far from the worst. A safari-themed 5×3 grid game, every dozen spins, players have the option to activate either the lion or panther bonus, all while collecting wilds and adding multipliers. Using the familiar 10, J, Q, K, and A symbols as well as different animals and wild symbols, Serengeti Kings is fun to play and still boasts one of the highest RTPs around.

2. Verify Your Age

According to Casino Lab’s standard KYC procedures, you’ll have to upload documents to verify your identity. They’ll ask you to upload a picture of your ID. Once your account has been verified, you can place your first deposit.

What is the house edge in slots?

Every online casino site you come across will have a house edge present in all casino games. Like the house edge you might find in land casinos, so too does online casinos offering the digitised version. You’ll find that the house edge differs depending on the online slot, or online casino game, you’re playing. This is a purposeful decision, as strategies and other factors can increase/decrease your chances of victory.

The house edge is otherwise known as the ‘hold’ of the game. Every pay table and bonus feature you come across have been carefully considered by a mathematician when working out the house edge. One of the largest misconceptions is that reels lockout to protect the house edge, which just isn’t true, and would be considered highly illegal.

The Best Slots Sites Online, and Their Top Games

Yoyos Wild

Prepare to feel a pang of nostalgia as you play Yoyos Wild, an online slot game based on everyone's favourite toy.

This real money slot comes with five reels, 25 paylines, and colourful retro background.

Can I Play Online Slot Machines in a Free Demo Mode?

Yes, many of today’s top slot sites allow players to test the games in demo mode. This allows players to get the hang of a slot machine before they risk real money or simply start playing online slots for the fun of it.

Where can I play this Slot for free/real money?

The best site to play Big Time Gaming Slot machines is partycasino, so that's where you should be headed if you want your games to get muy picante!.

Should I Play High RTP Slots?

RTP is one of three factors that determine the payout pattern of a slot game. The others are variance and top payout potential. A game with a high RTP is likely to return more of your money than a low RTP game, but this figure does not tell you everything you need to know to understand the maths of the game and whether it is the right slot for you.

Variance is also important because it will tell you how far from the RTP a game will deviate in its payout pattern. Low variance slots do not vary much in their pattern so you can expect to win roughly the advertised RTP in each session. High variance slots vary greatly and their unpredictability makes them high risk. A 96% RTP high variance slot may give one player astronomical wins in a short period, whilst another player may lose all their money very quickly.

Payout potential is also important because it tells you the maximum amount you can win in one spin, regardless of the RTP or the variance of the game.

So, to answer the question, RTP is a good indicator of the style of slot you are playing, and playing high RTP slots will give you more money back on your stakes. But keep in mind that variance and payout potential will also affect your experience too.

Are Online Slots Rigged?

Online slot games work in such a way at fully licensed casino sites that they simply can’t be rigged. This is because they use something called RNG (Random Number Generator) to determine the outcome and to ensure fairness and transparency.

Channel the power of the God of Thunder courtesy of Thunderstruck II from Microgaming. This is the second entry in the Thunderstruck franchise, one that boasts 5 reels with around 243 different winning combinations for you to discover. Another slot with a 96% return to player percentage, one that should be spun for the various free spin bonuses you have at your disposal. Keep an eye on the Loki bonus people.

Baccarat

Baccarat is a must for all James Bond lovers. It is 007’s favourite game, and many Brits like to emulate Fleming’s hero at the card tables at best payout online casino UK. RTP’s are in the high 98s, making it great value for money.

What is RTP?

RTP stands for Return to Player, and it is offered as a percentage, the amount indicates the likelihood of earning a payout over a number of spins.

Ultimately it lets you know how much you can expect to win from a given online slot game over its lifetime and provides you with details on your chances of winning. In many ways, the inverse of a house edge that you would find at a casino.

The return to player theoretically gives you an indicator of what you can expect back from a slot over a period of spins. For instance, if it is a 95% RTP then you would expect £95 returns over 100 x £1 spins. This is not guaranteed but it is applied to an infinite number of spins to give you a fair idea of your likelihood of regular wins.

The casino or slot site needs to have a form of edge to remain profitable, and this is expected. A 95% return to player percentage is deemed reasonable and anything above is often considered generous.
