Let us run you through each of the offerings this best slot site has to offer in 2021.
Play £10 slot games and win 500 free spins (2021 welcome offer)
New players who deposit from as little as £10 will have the opportunity to win up to 500 free spins on the Diamond Strike slot in 2021. This is the highest prize that you can win after your first-time deposit at Slots Racer, one that deserves praise; since Diamond Strike is indeed one of the best online slots 2021 by Pragmatic Play, carrying huge fixed jackpot prizes.
Remember, however, that 500 free spins are the maximum possible welcome bonus prize, but you might need to settle with 10, 20, 50, or 100 free spins on another slot game or free vouchers instead. The Mega Reel will define your reward randomly, following your first deposit of real money at Slots Racer.
Terms and Conditions apply to all the rewards from our Welcome Offer. These are along the lines of current industry standards, which are as follows: 65x wagering requirements, maximum win of £250 from the 500 free spins and the rewards apply on selected slot games only.
Over 800 online slots
If you take a minute to have a quick look in our available online slots, you will realise that there is no end to it. Our games are the products of Microgaming, Red Tiger, Leander and 20 more software providers. Quality is always the priority, while the online game types are unlimited. Check out the main categories of online slots that we offer below.
Over 200 games at Slots Racer fall under these two categories, which are hugely loved by our players even in 2021.
Slot Machines - there is no shortage of 3x3 reel slot machines on our site. These games are still very popular with some professional old-school players, so we would not fail to provide. Our favourites from this genre include 7s to Burn, Fiddle Dee Dough, and Down the Pub. Their bet levels are limited compared to other categories, but this does not limit the payouts - which can go over £200,000 from a single spin of the reels.
Fruit Machines - likewise, fruit machines are still loved by UK players, so we have incorporated this genre within our online slots catalogue too. Signature fruit machines on Slots Racer include Burning Desire, Fruit Shop, and Twin Spin. The latter has even evolved into Twin Spin Deluxe and Twin Spin Megaways, mixing the classic with a modern twist.
Based on our players' preferences, we have noticed that branded and themed slots are the most expected game releases which are instantly picked up by UK bettors.
Themed Slots - there are multiple themes that persist over the years, with video slots reproducing them and delivering a unique take to UK slot players. The best themed online slots on our casino site include Rainbow Riches, Rainbow Riches Pots of Gold, and Lucky Irish.
These three slot categories are not necessarily distinct, but it will be easier to understand what each offers by separating them into groups.
Video Slots - very often, all the above niches of slots are incorporated within the video slots umbrella term. We reserve this title for those truly deserving of this title. Such as Mermaids Millions by Microgaming, White Wizard by Eyecon, and Baracrest's Rainbow Riches Pick n Mix.
Megaways Slots - a rather recent emergence, the slots with not fixed paylines and gameplay seem to have shaken the whole industry. Play Fishin’ Frenzy Megaways, Reel King Megaways or Rainbow Riches Megaways to see what 100,000+ different ways to win actually means.
Slingo Games - lastly, the Slingo Originals company has also produced a big hit slot series, which you can now play on Slots Racer. A combination of bingo and slots with tons of bonuses and huge prizes are offered through beautiful re-imagination of themed games: Slingo, Slingo Rainbow Riches, and Fluffy Favourites Slingo are just a few of the available slingo games in 2021.
Play jackpot slots with high payouts
The word jackpot is a bit overused in 2021. When it comes to slots, there are different types of jackpots offered within them. We are proudly offering any jackpot slot game you might desire but let us first show you how these differ.
Slot machines vs jackpot slots
Many casino slots are designed to have three different gameplays incorporated simultaneously. Firstly, there is the basic gameplay, where players spin the reels and match symbols on the active pay lines. Matching 3 or more usually rewards in a win, while wilds and scatters are often apparent and increase the winning chances. Slot machines only offer access to the basic gameplay, also commonly referred to as 'base game'.
Bonus rounds are often the second level of slot games, which open new game rounds with multipliers, free spins, sticky wilds or pick me prizes. The prizes in bonus slots online tend to be much higher compared with slot machines, but they might take a while to trigger. Some of the most fascinating bonus slots in 2021 include Cash Stax, 9 Pots of Gold, and Starburst.
Jackpots are the third and most lucrative level that can be incorporated within online slots. These are usually offered in 3x different levels: minor, grand, mega. Their prizes change according to players' bet levels, but do not increase in response to repeated bets. Popular examples of fixed jackpot slots are Wolf Gold, Chilli Heat, and Beehive Bedlam.
Progressive jackpots, on the other hand, increase in size according to the players betting on them. They tend to pay out less often, but their prizes regularly exceed £1 million. Different progressive slots accumulate distinct bet percentage to be added in the total money pool; the most rewarding progressive games on Slots Racer are Irish Luck Jackpot, Rainbow Jackpots, and Mega Moolah.
There is a last group of jackpots on offer at this best slot site. These are triggered at random, without requiring max bet - neither are they adjustable based on the bet level. The jackpot king slots carry the title JPK at Slots Racer, with some of the most fun being Fishin Frenzy Jackpot King, Ave Caesar JPK, and Irish Riches Megaways JPK. All these slots accumulate a percentage from all other bets placed on jackpot king games, rewarding at random one lucky player with the total sum raised to this point.
New online slots added daily
New slots are constantly added on our site since we collaborate with so many developers. We follow trends and what players in the UK seem to love when it comes to slots online - and we deliver it to them. In certain cases, we also add tournaments and exclusive offers for new game releases.
2021 has been a great year for the UK slots industry, which can be reflected by the impressive new online slots we have added.
Street Fighter 2 - released last year by NetEnt, this branded game has stolen our hearts. With 7 different bonus rounds, maximum bets as high £700 per spin and an RTP of over 96% - it is a must play slot.
Gonzo's Quest Megaways - the impressive Red Tiger Gaming borrowed the traditional Gonzo's Quest and turned it into the most lucrative game to play. Wilds, x15 multipliers, over 100,000 different ways to win and the now-classic avalanche feature - position this Megaways game amongst the best slot games to play.
Rainbow Riches Reels of Gold - the classic Irish slot went through a great revamp, offering new bonuses, better graphics and an even higher RTP. With 97%+ return to player rate and over 3 distinct bonuses, what is not to love about this new slot game?
If you fancy new online slots, Slots Racer 'New' games tab is where you should always go weekly to find the top-rated new releases in 2021 and beyond.
How to play online slots?
We give you over 1,000 different reasons to join us and revamp your online gaming experience. If you feel that we could be the one for you, read through the steps required to sign up on our site and play online slots.
Firstly, click on the ‘Join Now’ button on the top of this page.
Provide Slots Racer with your personal and contact details.
Enter your address details and move on to third step, to complete the process.
Completing the sign-up process is easy, and you just need to perform a minimum £10 deposit to access the casino slots we offer. Since you are depositing funds, it would be clever to also opt in for our welcome bonus which adds value to your deposit. Nevertheless, after you complete the registration and payment processes, the following applies universally to online slots with slight gameplay differences. How to play:
Tap on your favourite game that is available on our casino site pages and sit back until it launches.
Set your bet levels and adjust the slot pay lines until you are satisfied with the total bet amount. Megaways games and some other modern slots do not have paylines.
Autoplay is available on many of our slots, as is Turbo mode; you can employ these to spin the slots reels automatically or fast, while you can also hit play every time to trigger the spin in the slot reels.
Following a rather quick animation, the symbols are going to fix on the reels. Matching 2 or 3 identical symbols results in a winning combination at most slot games, while scatters and wilds assist players in scoring higher wins.
At a basic level, this is how to play online slots, although in 2021 many slots online also carry some advanced bonus features.
One of the most exciting modern developments in slot game history is, of course, the increase in bonus features and bonus rounds available. These are becoming more and more accessible, much to our joy since online slots motion graphics and improved mechanics are easier to incorporate in 2021.
But what are bonus features in slot games? Well, for the most part, they are in-game extras that give the players chances to win more money or perhaps more often, with differing bonuses offering different prizes or effects. One of the most popular types of slots bonus is the free spins round and not without good reasons; as this often-rewarding casino bonus allows players to spin the reels for free, sometimes up to huge number of turns. Not only this, but some free spins rounds in online slot games will also add multipliers to your wins, helping you win big.
Make sure you keep an eye on what bonus features your slot games of choice have as they can really mix up your gameplay for the better. Fascinating slots with comprehensive and rewarding bonus features are Guns n Roses, The Goonies, and Bonanza by BGT.
Returning slots players promotions and loyalty bonuses in 2021

Other exclusive casino games
Most of our promotions apply to slots, but Slots Racer does offer a lot more than that. If you scan through our games lobby, you will notice that live dealer games, table games, bingo games, scratch and instant games are also apparent on this casino site. We will not expand too much on this, as we primarily play online slots, but we will just provide you with a quick heads up on what else is on offer at Racer casino site.
Table & Live Dealer Casino Games: Blackjack, baccarat, roulette, Sic Bo, and poker variants are offered in video and live dealer format. The latter are offered in a much lesser extent, but they are more than enough to satisfy your urges! Signature casino games that are very popular with our customers include Live Roulette and Vegas Strip Blackjack.
Bingo: We have a whole bingo section available, featuring 90-ball bingo, 80-ball, and 75-ball classic variants; while UK bingo fans can also try out our Friday Fun and Blast Bingo variants that offer the chance to win prizes of £500 or more.

Best online slots software providers
Slots software providers are pivotal to the success of the entire iGaming industry. The developers are the brands and people who create the online slots that we all play and love so much; certain players even have their favourite slot game developers for one reason or another.
Their work is not just important due to their ability to develop fascinating and fun slots online, but also due to the safety and fairness that their titles ensure. All the games we are supplying, and they power, have a random number generator incorporated within their software system, which ensures that each spin is unique to the previous one. They also display their return to player rate, so that players are aware about the edge that our online slots carry over them. So, who are the providers that we collaborate with to provide the best slots online?
Microgaming is perhaps the most well-known online slots developer there is, with this brand being closely tied to the rise of the online casino world in the 1990s. As one of the first brands to really nail down the fairest way to offer online casino in terms of random number generators and return to player rates, they deserve their acclaimed status in the history of online gambling.
In modern day, Microgaming continues to set the bar very high for every software provider; the graphics of their games are a bit dated, but their bonus features and usability is fascinating; popular Microgaming slots include Break Da Bank Again slot, Cops and Robbers, and Arcade Bomb.
This developer of online slots has shot to fame in recent years and became one of the most notoriously and unanimously loved brands in online casino as a whole. The reason for Yggdrasil's success is surely down to their love for the visual art and animated side of slot games, which they are absolute masters of. Their signature online slots available ta Racer casino include Gem Rocks, Vikings go Wild, and Vikings go Berzerk slot.
One of the newer names on the scene is Leander Games, but they are far from newbies themselves with an impressive collection of online slots to their name. Internationally acclaimed to the very meaning of the phrase, players enjoy their slot games from here to South America and from a Leander Games production you can expect a high standard of design and bonuses.
They have no issue with taking on an ambitious theme and with this comes ambitious graphics and gameplay too, as they really are pushing boundaries for what an online slot machine can be in 2021. All playable via smartphone devices, tablets and desktop computers, Leander slots that stand out are Gorilla Gold Megaways, Stardust, and Crazy Genie.
One of the longest-running developers in the realm of slot games is Barcrest, a brand who have been making fruit machines since before they even moved online. You are likely to be able to find games from this company up and down the country in pubs, clubs, chip shops and the like, even to this very day, with their incredible legacy on the casino industry felt strongly wherever you play casino slot games.
Pragmatic Play with signature titles like 3 Genie Wishes, and Red Tiger Gaming with the infamous Reel King Mega - are just a few amongst the other software providers that power Slots Racer casino in 2021.
Tips to play online slot games
Our blog is the best place to identify tips and advice on how to play slots online in the best way possible. However, we are trying to save you some time by touching upon the most important aspects involved in playing slots right here.
RTP - the return to player is a good metric of the edge that the casino has over players from each slot game. This, however, is an indicator of the return percentage over 1,000,000 spins approximately. 96% RTP or over is a great rate for any online slot.
Volatility/variance - this metric is also provided by the software providers of slots and highlights how high or low the wins will be; nonetheless, the level of wins is also dependent on their frequency. For instance, with high volatility slots you can expect fewer regular wins, but higher payouts.
Bonus features - we touched upon bonus features above, but we did not say that in 2021 you should never settle for an online slot with less than two in-game bonuses. Free spins and multipliers are the most common, but fixed jackpots and pick me features are also very rewarding.
Paylines - the paylines are slowly disappearing from slot games, with 247 ways to win, megaways, and other similar formats emerging. We believe that players with low budget should stick with classic slots, rather than different gameplay formats - since these tend to also carry a higher volatility.
Bankroll - the final tip is to always set a bankroll before you start betting at slots. Further, your bet size should not be over 1-3% of your bankroll. So, if you are playing slot online games with £100, you should bet £1 - £3 per spin maximum.
Always gamble responsibly
Lastly, Slots Racer site is a strong advocate of responsible and safe gambling, always striving to ensure that our players are getting the most from their gaming experience through our best slots online. Links to GamStop, begambleaware.org, and to the Gambling Commission can be found in our footer, which provide help to players who need it.
Those that feel like suffering from gambling addiction, should always set deposit limits in line with their budget; this can be done at any given point at Slots Racer. Problem gambling is not something that UK players should be ashamed of, and it always helps to spot the signs before they get worse.
Have a look at the UK gambling laws if you want to learn more on this topic, and remember that when the fun stops, stop.
Did you know this about online slots? (FAQs)
Check below some of the most common enquiries that we receive at Slots Racer from our players. This might help you solve any issues you might face quickly, without getting in touch with our support team.
Are the slot machines rigged?
Brick and mortar casinos were often reported for cheating players, by changing the ‘Return to Player’ and affecting the winning chances massively. With online slots, however, this is not possible. The Gambling Commission and other Gambling Regulatory bodies ensure that all casinos and slot sites adhere to their guidelines. The RTPs of each slot game is available for players in advance, while a Random Number Generator (RNG) operates within the slot machine to ensure that each spin is unique. This means that you could win the jackpot twice in a row, but also that you could experience a long losing streak. To be certain that you are not being scammed, always play on legal casinos like Slots Racer, as we are licensed and regulated by the UKGC and the AGC.
What are online slots?
So, what exactly are online slots? Well, also known as video slots, slot machines, online fruit machine and pokies, depending on whereabouts in the UK you are, these online gambling games have risen to popularity in recent years and became one of the most popular ways to have a flutter online. If you did not know already, online slots derive from those classic casino games with reels, like fruit machines that once adorned the corners of pubs up and down the country.
Online slots are quite simply the online version of these games, bringing with them new features and possibilities such as great graphics, bigger jackpots, all sorts of add-ons, and extras that simply were not possible with the age-old offline format.
What are the best online slots to play in 2021?
When it comes to whittling down the best online slot games to play, you have a real challenge on your hands, purely because the standard is so very high these days and the selection is vast to the point where it feels like the choice of slots is never-ending. Online casinos make sure to offer plenty of games in this genre to their players thanks to the incredible popularity that they hold among the players.
From jackpot slots to megaways slots, fixed pay lines to elaborate themes, there are lots of different ways to play video slots and what makes a slot game one of the best is somewhat subjective.
To make our picks we have taken into consideration many factors such as the originality of games, the detailed nature of their theme, the quality of graphics and gameplay, sizes of prizes, jackpots, and other wins, as well as how much they cost to play. Here are a few of the most popular slots to play on Slots Racer in 2021:
When were slots first invented?
The slot machine itself dates back well over a hundred years (1890s to be precise), since Liberty Bell first introduced the poker machine into bars and taverns across San Francisco in California. The prizes back then were just free drinks from said bar and even a few cigars, so when you realise just how much more can be won in online video slots today, you will realise one of the ways that slots have greatly evolved. Similarly, the ease of now playing the once chunky fruit machines as phone slots on your own handheld smartphone device shows once again how far into the future of casino we really are.
What slot games pay real money?
Many sites offer free slots and demo slots to players, which do not pay real money. However, all our slots online can be played with and for real money! Besides our welcome offer that has wagering requirements in place, any deposit you make will allow you to spin the reels on our best rated online slots. Each slot game we offer carries a description of the maximum prize you can win, so make sure that you read it beforehand. Some of our titles offer more than 5,000x your original bet - so adjust your bets based on the pay-outs that you are after! Highest paying real money slots here include:
Are there no deposit slots sites today?
No deposit slots sites used to be very common, but they are not very common in 2021 due to players taking advantage of these casino without deposit offers. If you want to play without spending real money, you can have a go on demo slots for free! As far as our slots site is concerned, the best we can offer to new players is our free spins welcome bonus, which can reward up to 500 free spins on Diamond Strike with a £10 qualifying deposit!
Does Slots Racer offer just online slots to players?
We are primarily a site focusing on bringing the best slot machines, best online slots, jackpot games and video slots in one place for spin enthusiasts. However, we also have a huge collection of classic casino games in place, such as real money Blackjack, UK Poker variants, Live Dealer Roulette, Bingo variants and we are planning to add more soon. Ah, and do not miss out on our Scratch cards!
Which slot machines have the best bonuses in 2021?
Most slot machines released after 2015 have a bonus round in place; if you are looking for slots bonuses, we suggest that you stay away from fruit machines and play any of the following games:
If you have not played any of the above yet, you can deposit £10 and play them on our site today. Some provide £200,000+ in prizes.
Can I play slots online free?
Yes, you can. Free online slots are available in demo mode, through the form of free bets and no deposit casino bonuses. Demo slots are the most common, but the other two options could also be available on some sites. However, it will be hard to beat the wagering requirements and withdraw your bonus winnings.
What is the best online slot to play?
It is hard to conclude on a single game amongst the thousand slots we, and other sites, offer. At the end of the day, it is down to personal taste. However, if you ask us to pick one, we will go with Street Fighter 2 slot. It has amazing bonuses, great graphics, quick gameplay and one of the most fascinating themes!
What are demo slots?
Demo slots are a feature that is apparent on some online sites, which allows players to try out the game without paying, just like free spins no deposit do. In certain cases, you might not even need to register to play. Demo slots are great for beginners or for trying new slot releases.
Can you win money playing online slots?
If you join a real money slot site, yes you can win good amounts of cash. It all depends on your bet range, as this can start from £0.10 up to £500 per spin. The winning amounts from each are obviously completely different, but in both cases you can make real money if you get lucky!
Any references to bonuses and free spins are subject to the following terms: New players only, min deposit £10, £8 max win per 10 spins, max bonus conversion equal to lifetime deposits (up to £250), 65X wagering requirements and full T&Cs apply. Please see our promotions page for more information.
Please note that the RTP may change from time to time. For accuracy, see the information of the slot game in question (accessible by clicking 'Play' on the game logo from our 'All Games' tab. You'll need to be logged in to do this)
