Online casinos are locked in competition with one another and one effective way of competing is to improve payouts and RTP. Casino users always look for RTP and the best payouts when they select their favourite casinos. The RTP and payout rate for the entire casino is a calculated average that combines all the different games offered by the casino. We usually talk about RTP (Return to Player) and payouts for individual slots and games, but it can be used to measure the quality of individual casinos as well. Below we have mentioned some of the best online casino payouts in the UK. They all share elite RTP percentages and have multiple games that go all the way above 99%+ in payout percentages.

PartyCasino operates with an average RTP of 95.35%. However, some of their online slots have payout percentages above 98% and all Blackjack-games have RTPs over 99%. Always remember to look for the particular game’s payout percentage rather than the casino’s. That remains the most important thing! Online Slots with the Best Payout and RTP There are many things to consider when you decide to play an online slot, but the payout rate (or the Return to Player rate) is usually one of them. The RTP describes how much of your stake you are likely to win back on average. The higher the RTP, the better value the slot played is to you. We can illustrate the relationship between Online Slots and RTP with an example: If you play Thunderstruck II one hundred with a £1 stake, you will have invested £100 in the slot. The slot’s official RTP is listed at 96.35%,On average you will earn a return of £96.35. Of course, that is by no means a certainty, since the RTP is an aggregated average based on a calculation. Most times, your losses or winnings will fluctuate strongly from the RTP, which is a theoretical number, rather than a number that predicts your winnings with precision. The majority of online slots operate with an RTP between 95% and 98%. With an impressive RTP of 98%, the 2013-classic Blood Suckers from Netent has one of the highest RTPs on the market. The best payouts among online slots in the UK often goes to slightly older slots. Of course, there are other things to consider, such as gameplay, progressive jackpots, design and the slot’s volatility. But payouts and RTP are some of the most important factors. List of Slots with the Best Payout in the UK 1. Mega Joker – 99% Mega Joker is a classic slot game offered by the leading software developer, NetEnt. NetEnt has always advertised the slot with a 99% Return to Player rate, which remains the highest on the market for any online casino slot. The 5-payline progressive jackpot slot does technically have an RTP at 99%, but the game involves a number of complex features, such as the Supermeter, which means you have to follow a very specific strategy to play in accordance with the 99% return.

The 25-payline video slot features Wild, Scatters and Free Spins but is mainly known for its lucrative RTP. Play 1429 Uncharted Seas at Rizk Casino here! 3. Blood Suckers – 98% Blood Suckers is vampire-themed slot powered by the software developer NetEnt. Originally released in 2009 with an RTP of 98%, Blood Suckers was followed by a NetEnt sequel in 2017. Like many of the other best payout online slots, Blood Suckers isn’t the most fancy slot – the 5 reels, 25 paylines and a few vampires won’t attract many players, but the fantastic RTP still makes it an enticing option. Play Blood Suckers at Leo Vegas here! 4. Devil’s Delight – 97.6% Devil’s Delight is another 20-payline video slots developed by NetEnt. The slot is death-themed and features both the Devil and a Reaper symbol, but the slot’s payout percentage is very much alive. With an RTP of 97.6%, Devil’s Delight stands as one of the most competitive slots on the market, still years after its release. Play Devil’s Delight at Genesis Casino here! 5. Magicious – 97.6% Magicious is powered by Thunderkick and operates with 5 different reels and 10 paylines. The 97.6% RTP makes the slot the final addition to our list of the best payout online slots. This list of best payout online slots in the UK is certainly not exhaustive, but it is worth noting that many of the most popular online casino slots are absent. Take Starburst as an example, one of the most popular online slots in recent years – yet it only has a payout rate of 96.1%. The same goes for Gonzo’s Quest, another player favourite, with a payout rate of 96%. This is a good reminder that although payout rates are important, casino players take other things into consideration as well when deciding where to play. Play Magicious at Leo Vegas here! How To Make an Online Casino Withdrawal Withdrawing money from your online casino account has never been easier. Most casinos have now enabled mobile phone withdrawals as well as a desktop solution. Some casinos even allow you to call them to state the specified amount you’d like to withdraw, and where you would like to receive the money. Firstly, you will need to access your Casino account, either on a desktop solution or your mobile phone. Secondly, you need to open the Cashier and select your preferred withdrawal method. Multiple options will appear but different regulations exist in terms of fees, maximum amount and processing time. Make sure to read through our guide to identify the best online casino payouts. Thirdly, you specify the amount you’d like to withdraw. Most casinos operate with a minimum and maximum withdrawal amount. The size of the withdrawal does not usually impact the withdrawal time. However, if you are making a very big withdrawal or your first withdrawal, the casino might employ additional security measures to verify your identity etc. There is also the casino’s own processing time for the withdrawal which varies from operator to operator.
