Everything you need to know about high paying slots

If you’re a fan of online slots, you probably want a decent chance of landing a win and making some returns. What better way to do that than by trying your luck on the highest paying slots? Luckily for you, the Casino Genius team has scoured the internet to bring you a list of the best online casinos with high paying slot games. But just what is it that makes a high paying slot, and how can you find the best paying slot machine online? Let’s find out.

RTP

The return to player (RTP) is what defines how well paying a slot game is. Displayed as a percentage, the RTP shows how much of your total spend you might, theoretically, expect to win back over an extended period of play. So if a slot has an RTP of 96%, you could, in theory, expect to win back £96for every £100. The industry average RTP for slots is somewhere 94%-96%, so we’d consider anything above 97% to be one of the highest paying slots on the market.

It’s important to know that the RTP is far from a guarantee. It’s a measure of the average winnings paid out to all players and is based on an infinite period of play, so you can easily be on track to win less, or more, at any one time. Think of RTP as more of a rough estimate, rather than an exact figure of the returns you should expect to win back.

All casinos and software developers that are licensed by the UK Gambling Commission (UKGC) are required to display the RTP of games to ensure transparency. This makes it easier to compare the best payout online slots. To check the RTP online, simply click on the ‘information’ or ‘?’ symbol once you load up a slot game.

Progressive jackpots

You may be thinking that the best slots to play are those that pay out the highest jackpots, but that isn’t always the case. This is because of something called variance, which refers to the frequency at which a slot pays out, as well as the size of the potential prizes. If a game has low variance, it’s expected to pay out small amounts often. A high variance game, on the other hand, won’t pay out as frequently but is more likely to pay out large windfalls when it does.

Most progressive slots, like Microgaming’s Mega Moolah, are high variance. This slot holds the record for the highest payout online slot jackpot, paying out over £16 million to one extremely lucky player. However, the RTP of this slot is only 88.12%, which is pretty low. So while you’ll be in line for a big payout if you do land a lucky spin combination, on average you’re less likely to win on Mega Moolah than you are on the highest RTP slots on the market.

Highest RTP slots on the market

Every online casino and slot site will have its own library of top slot games, but here are a few examples of some of the highest RTP slots that are currently on the market.

Goblin’s Cave

This Playtech slot has a whopping RTP of 99.32% when using max bet, a figure you’re very unlikely to see beaten. Goblin’s Cave is a fairly simple slot with 3 reels and 3 paylines, but the hold feature gives this game something extra. Every time you place a bet and hit spin, you then get to choose whether to hold any symbols before spinning again, adding more of a tactical element to this game.

Ugga Bugga

Another offering from Playtech, Ugga Bugga’s max bet RTP of 99.07% makes this one of the best RTP slots on the market. Like Goblin’s Cave, this 3 reel, 10 payline game also has a hold feature which can give you a better chance of landing a win on every second spin. There’s also a handy wild symbol, and if you line up 3 across a reel you’ll hit the game’s jackpot, putting you in line for a payout 1,000 times your bet per line.

Mega Joker

NetEnt’s Mega Joker is a 3 reel, 5 payline progressive jackpot slot, with a max RTP of 99%. Based on the classic fruit machines of old school casinos, you can choose to play on the bottom reels, or move up to ‘supermeter’ mode for a chance to win bigger prizes. The progressive jackpot is paid out randomly and doesn’t require you to bet the maximum amount, so anyone is in with a chance of landing a win on this high RTP slot.

Frequently asked questions

Can I use bonuses on the highest paying slots?

This depends on the casino in question, but most casinos state that slots bonuses, like free spins, can only be used on certain titles, and these don’t tend to include the highest payout slots. On the bright side, you can usually use bonuses on games with a respectable RTP, such as NetEnt’s Starburst, which has a payout rate of 96.1%.

Are online slots fair?

Yes, as long as you’re playing at a licensed casino or slot site. Licensing bodies, such as the UK Gambling Commission (UKGC) ensure that slots use random number generators (RNG) to produce the outcome of spins. This makes every spin is random and independent. These authorities also test and audit slot to the advertised online RTP is accurate.

Can I play high paying slots on my mobile?

Yes. All of the best online casinos have mobile-friendly websites, meaning you can spin the reels while on the go. Many of the top sites also have native casino mobile apps, which can be downloaded on iPhone and Android. Mobile casino apps can make playing mobile slots smoother and easier, and also have push notifications to keep you in the loop on the latest slots releases and slots bonuses.

Can I play high paying slots at new online casinos?

Yes. High paying slots aren’t exclusive to any type of casino site. In fact, the best online casinos, including new slot sites and new casinos, offer a range of titles with high RTPs, so you’ll be able to spin the reels of high RTP slots and give new sites a spin.

What is the house edge?

The house edge is the opposite of RTP, and refers to the advantage the casino has over the player. If a slot has 97% RTP, the house edge for that game is 3%, meaning the casino has a 3% advantage.

Do I need to deposit to play the highest paying slots?

Yes, if you want to have a chance to win real money. The slot sites on our list offer a range of payment methods including PayPal, pay by phone bill and paysafecard, so depositing is easy, whatever your preferences. If you just want to play slots for fun, you can play free demo slots, but keep in mind that the majority of progressive slots are only available as real money games.
