Best Online Slots
What makes the best online slots?
Typically, when our players look at the best online casino slots, they look for a unique combination of aspects. The very best online slots have fantastic graphics, brilliant gameplay, unique features, a high potential win and an above-average Return to Player. However, creating online slots that fit all of the aspects above is rather difficult, considering there are dozens of brilliant providers all looking to create the ‘next big thing’ in slots gaming. Of course, there are a number of providers who tend to push more towards some aspects than others, some will completely negate the graphical side of a slot and purely focus on gameplay, while others will provide a low RTP in exchange for a massive maximum win - these types of games are often referred to as Jackpot slots. Then again, other providers focus on trying to provide a brand-new style of gaming, a prime example of which is the Megaways slots mechanic by Big Time Gaming, which has been licensed out to multiple providers and is now widely regarded as one of the best online slot mechanics in the world today.
What are online slots?
Slots are the mainstay of Vegas casinos. A number of players play blackjack or roulette during their time in Vegas, but when you sit in a Vegas casino, slot machines around the building are filled. These games require very little thought and can be played at much smaller prices than the previously mentioned games. These games are created using a random number generator which creates millions of different outcomes every second. There is no memory, no tracker, no guarantees - just an algorithm that makes every spin unique and unpredictable.
Are the most popular online slots the best?
Ultimately, the best online slots will differ due to players’ opinion and it can be perceived that the most popular online slots are the best - otherwise, why would they be played in such high-volume? Let’s start off by looking at the statistics of the second half of 2020.
Over half a million game sessions were played in the second half of the year. 26% of those were live casino games or table games. This means a whopping 74% of those games were online slots. The two most popular slots were the Book Of Dead slot and the Starburst online slot, both of which had over 15,000 players and just under 3% of sessions. However, the most popular slot series was Rainbow Riches, which collectively had over 22,000 players!
So, by this logic, Starburst, Book Of Dead and Rainbow Riches are the three best online slots in the world, right? Not in our opinion. All three games are truly fantastic slots that have lasted the test of time and have been fan-favourites for years. They’ve collected such a large following that they’re always going to be a success. However, when you refer back to the list of necessities for the best online slots, these games were definitely the best of their time, but some newer slots definitely deserve their time in the spotlight.
Best Online Slots of 2021
We’re only one full month into 2021, but we believe that we know what one of the best online slots of 2021 will be. The brilliant Neptune’s Fortune Megaways contains all the brilliant features of Megaways slots, the unique underwater theme and actually fits all of the necessities required to make one of the best online slots! With fantastic graphics and gameplay, an above-average RTP and a max win of 1,000x the player’s stake.
Best Online Slots in regards to Stated RTP
Best Online Slots from Red Tiger
Red Tiger Gaming slots are some of the very best on 21.co.uk and considering how many slots they have released in recent years, it’s difficult to pick one slot from the masses. A special mention has to go out to the Rocket Men slot as it’s so ridiculous, it’s brilliant. However, in reality, their slot which best matches our criteria is the Dragon’s Luck slot, which has fantastic graphics and gameplay and is one of Red Tiger’s highest in regards to Return to Player, with a max win of over 1,000x your stake!
Best Online Slots from Pragmatic
Pragmatic Play are a slot provider who keeps getting better and better. The sky's the limit for this popular provider and, in our opinion, their best is actually a release from 2020. The Wild Machine is a slot that is inspired by the very popular film, Back to the Future, and contains as many wacky bonus features as the film contained wacky inventions. The main bonus feature is the wonder wheel, which can contain five different outcomes including cash prizes and two Free Spins bonus rounds, which include either stacked wilds or a brand new set of reels depending on which of the bonuses you win. With over 7,000x the player’s stake available to win, a high volatility and Return to Player, all three attributes are well above average and with the brilliant graphics and gameplay that come with the slot, it is no surprise to see 21.co.uk players have reacted positively to the slot.
Best Online Slots from Novomatic
Now, Novomatic are a provider who are incredibly reputable, due to the quality of their older slots. Our favourite is the Book Of Ra series, but if we had to choose one particular slot, it would be the original game. Released in 2005, Book Of Ra epitomised what the casino industry was set to become and set the benchmark for future casino games. This slot has fantastic gameplay and a very high volatility, but also contains a whopping 5,000x stake max win - which is bigger than some of the jackpot prizes on-site. Novomatic have created a number of great new online slots as well; however, be sure to check them out if you get the chance.
Best Online Slots from Blueprint
As one of the top casino providers in the world, you can guarantee that you will find Blueprint Gaming slots all around the world. However, 21.co.uk is where you can find the vast majority of their slot games. The reason why Blueprint Gaming is so popular with casinos and players alike is because of the quality of their casino games. Our most popular games section is filled with Blueprint slots such as Rainbow Riches, but their best online slot in our opinion is Cop the Lot. Cops Vs Robbers is the theme, well-known around the world, but Blueprint added a truly unique twist with a series of bonus rounds such as the trail bonus, free spins, line picker and the illustrious Jackpot King. All of these bonuses are rich with unique segments that make the Cop the Lot slot one of the best on 21.co.uk.
Best Online Slots FAQs
Q. What is the best slot machine to play online?
There is no such thing as the ‘best’ online slot, as all of our players have different tastes and likes. That being said, here are five classic slot machines that we believe will fit all players.
Q. What is the average RTP of the best online slots?
The average RTP for online slots is just under 96%. However, this will often depend on the volatility of a slot. For the slots with the biggest wins, the average RTP will decrease, but for slots with the best gameplay and a series of bonus features, the RTP will be slightly higher. Any slot with over 96% is classed as a slot that has an above-average RTP.
Q. Is there a best time to play online slots?
For 90% of slot games, the answer to this question will be no. However, for those players who enjoy the Progressive Jackpot feature, they will know that playing these games after the jackpot has just been won is a worse time to play than when the Jackpot is at its peak.
