What Makes a High Paying Slot?

The return to player (RTP) is the percentage of all money wagered on a slot game that is paid out back to players. The higher the RTP, the more often the slot pays out on average. So if a game has an RTP of 96%, you could, in theory, expect to get back 96p of every £1 you wager over an extended period of play.

However, RTP isn’t quite as simple as that. This is because it’s an average calculated based on the wagers all players put into a game, and is based on an infinite number of spins. This means you can easily be winning back more or less than the RTP at any one time. For this reason, it’s best to use the RTP as a rough estimate of what you could win, and don’t be surprised if your actual returns are some way off.

Most online slots have an RTP of 94% to96%, so any game with an RTP of 97% or more would be considered a high payout slot. However, these RTPs aren’t always set in stone – some slots’ RTPs change depending on how much you wager. For example, in certain titles, you have to bet the maximum amount in order to activate the highest possible RTP.

 

How to find the RTP of a slot game

Luckily, finding out the RTP of online slots is relatively easy. This is because all UK licensed casinos and software developers must make game RTPs easily accessible in order to ensure transparent gaming. Once you load up a slot, simply click on the ‘i’ or ‘?’ icon to find the RTP.

Progressive Jackpots

If progressive jackpots are famous for their life-changing payouts, then the titles funding them must be the best paying slots, right? Well, quite possibly, but only if you win the elusive jackpot, which is easier said than done.
Let’s look at an example. Microgaming’s Mega Moolah is holds the title for the biggest ever online slot payout- one very lucky player bagged more than £16 million on this game. You might think that this makes Mega Moolah the “highest paying slot”, but this title has an RTP of just 88.12%- that’s pretty low on the RTP spectrum. If you get lucky enough to land a rare win, it’s likely to be a bigger prize. However, on average you’re far less likely to land some returns on Mega Moolah than on the best RTP slots.
This comes down to variance, or volatility, which refers to the size and frequency of online slot payouts. Low variance means small prizes that payout often, while high variance slots payout less frequently are more likely to hand out sizeable returns when they do.
Most progressive slots are high variance, so you may end up waiting longer for a win than with other games. A progressive jackpot can be standalone, which means it is individual to one game, or pooled between games. In these cases, wagers on multiple titles contribute to the prize fund, so top prizes tend to grow larger and faster.

Best RTP progressive jackpot slots

Looking for the best of both worlds? We’ve picked out some of the best slots to play if you’re looking for a progressive jackpot and high RTP.

Mega Joker – 99%

NetEnt’s classic slot Mega Joker doesn’t just give you the chance to win a progressive jackpot- it’s one of the highest RTP slots with a payout rate of 99%. Unlike some progressive games you don’t need to max bet to have a shot at the jackpot, though your chances do improve the more you bet. You can either play on the bottom set of reels, or try out the ‘supermeter’ mode to go for bigger prizes.

Frequently Asked Questions

  • Can I use bonuses on the best payout slots?

    It’s unlikely. Pretty much all casinos limit welcome bonuses like free spins to certain titles, and these often exclude progressive jackpot games and the highest paying slots. You’ll still be able to use your spins on top online slots with respectable RTPs, though. For example, NetEnt’s Starburst has a payout rate of 96.1% and is one of the most popular slots for free spins bonuses.

  • Do I have to deposit to play the best RTP slots?

    Yes, if you want to play these games for real money. Luckily, our recommended best online casinos offer a range of fast and secure banking options including PayPal, Neteller and Skrill, so you have plenty of choice. Most sites offer free demo slots so you can play slots for fun, but progressive jackpot games are often excluded.

  • Which is the best paying online casino?

    The best paying online casino is the site which pays out the most to players on average, but there’s no easy way to check this. If you’re looking for the best payout UK online casino, you should check out the games library to see which sites offer the largest number of the highest payout slots.

  • Can I play the best RTP slots at new online casinos?

    Yes. Casinos often partner with different software developers, so the games on offer vary, but you can play high RTP slots at the majority of new casino sites. Some of the best payout online slots in the UK, like Goblin’s Cave, aren’t as widely available as other games, so you may have to search a bit harder to play certain titles.

  • How do I withdraw at online casinos?

    If you land a win on the best RTP slots and withdraw your returns, head to the cashier page, enter in your chosen amount and hit request. Make sure to read up on withdrawal limits and processing times- check out our fast payout casinos for instant withdrawals.
