Best Online Slots to Play in 2021
The best online video slot games are those that strike a balance between the big wins, reasonable volatility, huge jackpots, and high payouts. Recommendable slots for UK players that meet these expectations include Mega Moolah, Gonzo’s Quest, Starburst, Blood Suckers, and Thunderstruck.
Top Video Slots
Mega Moolah by Microgaming is one of the most popular slots among players and is dubbed as the ‘millionaire-maker. This nickname suits Mega Moolah perfectly based on its Guinness Book of Records of the online game with the largest payout ever.
Mega Moolah is a 5 reel slot with 25 paylines, and it features an African savanna theme. This slot has a massive progressive jackpot, and there are 4 jackpots that can be won during the base game. These progressive jackpots include the Mini, Minor, Major, and Mega Jackpot. The Mega jackpot guarantees a payout of up to £1,000,000.
The Mega Moolah RTP is 88.12%, with the minimum bet set at £0.01 up to a maximum of £6.25 per spin. Although the max bet limit is relatively low, you still get a chance to win either of the four jackpots.
Powered by NetEnt, Gonzo’s Quest is a Mayan themed slot featuring 5 reels and 20 paylines slot. This slot has numerous bonus features to boost your chances of winning, including multipliers, scatter symbols, wilds, and free spins.
What’s even more rewarding are the Avalanche Reels, which are activated every time you match a winning payline. When this happens, the increasing multipliers up to x5 will help you land several wins in a single spin. Another feature to watch out for is the Free Fall feature, which comes with a boosted multiplier meter.
You can place your bet from as little as £0.20 up to a maximum of £50 per spin. Gonzo’s Quest RTP is 96%, and the most you can win in the base game is 2,500x your bet per line. However, if you are lucky to activate the avalanche feature, your wins will increase with every successive win up to a maximum of 5x.
Starburst also tops the list of the best online video slots games in 2020 with its vibrant features and impressive bonus features that help boost your winning chances. The slot is developed by one of the leading software developers, NetEnt. One of the features that stand out in this slot is the Win Both Ways feature, which allows players to complete winning combinations from left to right and from right to left.
Starburst is a 5 reels slot with 10 fixed paylines, and you can set your wagers from as little as £0.01 up to a maximum of £100. Some of the lucrative bonus features to watch out for include expanding wilds and re-spins. With a 96.09% RTP, you can expect reasonable payouts.
Blood Suckers is another slot from NetEnt that ranks among the best UK slots. This vampire-themed slot features 5 reels and 25 paylines, and you can spin from £0.025 up to £50. There are several symbols that are designed to help you form winning combinations; they include scatter symbols, bonus symbols, and wild jokers. The bonus symbols include the Vampire Slaying bonus feature and the free spins features.
If you are lucky to land 3 or more vampire-slaying bonus feature, you could win up to 203.2x your total stake. On the other hand, landing 3 or more vampire bride scatter symbols could award you up to 100x your total wager plus 30 free spins.
You can expect the biggest possible payouts going up to 187,500 coins during the free spin rounds when you fill all the cells with Wilds. Blood Sucker has an industry-leading RTP of 98%, which is why this is a must-play slot.
Another of Microgaming’s top online games is the Thunderstruck slot, which features 5 reels and 9 paylines. The Scandinavian mythology theme is well elaborated, more specifically Thor, the God of Thunder. The slot offers big wins courtesy of the many bonus features. You can start playing from as little as £0.09 up to a maximum of £45 per spin.
High paying symbols include Thor’s hammer, a horn, a castle, and similar items related to Norse mythology. Thor himself is the wild symbol and can pay up to 10,000 coins for landing 5 of the symbols on a payline. The Ram symbol is the scatter, and landing two of these symbols activated the free spins bonus. If you land 3 or more scatter symbols, you will receive 15 free spins and a cash prize going up to 500x your stake.
The Thunderstruck slot’s RTP is 96.10%, and while it does not have a progressive jackpot, the max possible win of 270,000 coins is an impressive amount.

Online Video Slots with the Best Payout Percentage
As earlier mentioned, the best online video slots are those with not only high jackpots but reasonable payout percentage. Casino slots with high RTPs are highly recommendable, especially if you are looking to boost your winning chances. It is important to keep in mind that the theoretical RTP alone does not define the slot’s actual potential payouts. Thus, it would help if you considered other factors, such as the slot’s variance/volatility.
A high variance slot offers huge but less frequent wins, while a low variance slot offers small but frequent wins. Thus, if you are looking for online slots with the best payout percentage in the UK, you have to look into the variance. Here are some of the best paying online slots
|Rank||Slot||Payout Percentage||Slot's Volatility|
Book of the Dead
1429 Uncharted Seas
Reels of Wealth
Game of Thrones

Online Casino Video Slots Guide- How Do Online Slots Work?
Online video slots are the easiest games to play since they don’t have any specific strategy that players must use to win. You only need luck! Even so, there are various aspects that you should know about video slots to help you choose the best slots.
Types of online slots
Various types of online slots vary based on the number of reels, paylines, payouts, and features. Online slots can be divided into 5 key categories:
Classic slots- These slots are also known as ‘fruities’ and they commonly use symbols such as cherries, lemons, liberty bells, lucky 7s, and high poker cards.
Video slots-Unlike traditional slots, video slots don’t require mechanical levers and reels; instead, you just need to press a digital button to get started. Current video slots online fall under this category.
3 reel slots- This is the simplest form of online slots that is based on the classic Fruit Machine games. The slots feature 3 columns and 3 rows of symbols. The middle row is the payline
5 reel slots- Rather than the one payline in the 3 reel slots, the 5 reel slots can have up to 100 paylines. This increases the number of winning combinations, and players have a better chance of hitting a win.
3D slots- These are the most recent forms of slots, and they come with 3D animated graphics and animated characters. 3D online video slot games feature well thought through storylines, impeccable audio effects, and contemporary themes.
i-slots- i-slots are the newest entry in the slots market and are already becoming a favorite of video game players. These slots offer interactive gameplay where players have the liberty to create their own storyline. Only a few casinos such as Guts Casino offer these games, but we can expect this to change over time.
Branded slots- These slots have been gaining popularity over the past few years mostly because they follow a narrative based on either a popular movie or TV show. Some of the branded slots include Guns’ N Roses, Game of Throne, and Britain’s Got Talent.
Progressive jackpots- These slots feature a jackpot that steadily increases every time someone plays until one lucky player lands the jackpot. Once the jackpot has been won, it resets and starts again. Some progressive jackpot slots have payouts worth millions.
Special symbols in video slots
Online video slots come with bonus symbols and features that are aimed at boosting your chances of winning. Different video slots online come with varying special symbols, but the most common and rewarding bonus symbols include:
Wild Symbol- When this symbol appears on the reels, it replaces all other symbols except the scatter. This helps you complete a winning combination on a payline. Some slots feature a Wild multiplier that helps complete a combination and multiplies the wins obtained.
Scatter Symbol- The scatter is another rewarding symbol that can activate the free spin or the bonus game feature. The more the number of scatter symbols you land on the reels, the more extra spins you will be awarded.
Multipliers- This symbol increases your winnings by its numerical value, such as x2, x5, or x15.
Online Video Slots Bonuses and Free Spins
Online casinos use lucrative welcome bonuses to attract new players and reward ongoing promotions to keep existing players motivated. Most welcome bonuses match your first deposit and award free spins, which could either be attached to a specific slot or not.
100% welcome bonus up to £100 plus 50 free spins on Starburst
This means that when you make your first deposit and claim this offer, you will be awarded 50 free spins. However, these free spins can only be used on the Starburst slot.
However, free spins are not always ‘free’ since they come with wagering requirements that must be met before you qualify to withdraw any winnings obtained. Typically, any winnings obtained from the free spins are credited to your account as bonus funds, and these bonus funds will then be subjected to playthrough requirements before you can make a withdrawal.
The wagering requirements could range from x10 to x30, while some could go up to x50. Thus, before claiming slots bonuses, be sure to read the attached T&Cs and make sure that the wagering requirement is attainable based on your budget limit. Ideally, you want the largest matched deposit bonus with as many free spins as possible and the lowest rollover requirements.
Apart from the matched deposit bonuses, some casinos offer free online slots no deposit bonus. This sign-up offer does not require you to fund your account and is credited to your account immediately after signing up. This is an offer worth claiming since you can earn free money without risking your own.
Slots Payment Methods
The best real money slot sites offer a wide range of payment options for both deposits and withdrawals. The most popular payment options for UK players are credit and debit cards. This is one of the safest payment options. Players using these options are not restricted from claiming the welcome bonus, as is the case with e-wallet payment options such as Skrill, Neteller, and Paypal.
Slot payment methods are divided into several categories:
Credit/Debit Cards- These include Visa, MasterCard, and Maestro. You can use these for both deposits and withdrawals, and while deposits will be processed immediately, withdrawals can take up to 5 working hours.
E-wallets- These are popular options for players who are not comfortable sharing their actual bank/card details. More so, e-wallet payments are processed instantly, and the transaction fees are considerably low. These E-wallet options include PayPal, Skrill, Neteller, and EntroPay.
Cryptocurrencies- Cryptocoin such as Bitcoin and Litecoin have gained popularity among UK players for their anonymous transactions. With these payment options, you are guaranteed safe and untraceable transactions. However, these currencies are highly volatile, which could affect the exchange rate.
Bank Transfer- wire money transfer is recommendable for large payments to and from a casino. This is the safest payment option when dealing with huge amounts, but it also takes the longest to process.
Other recommendable payment options for UK players include;
Playing Online Video Slots for Free Vs Real Money
The best UK slots casinos offer players the option to play for free and real money. The free to play options are great for beginners looking to learn about the slots and those players looking to pass time on the reels without risking their money.
Free online video slots offer the same gaming experience as when playing for real money, with the only difference is that you cannot withdraw any winning obtained. Also, not all online slots have a demo version, which limits the number of games you can play for free.
Although free video slot games are fun to play, nothing beats the thrill of playing for real money. You not only get a chance to win big cash prizes, but you also have more game varieties. Playing for real money is also a great option to explore additional slot offers such as real money bonuses.
Unlike the demo games which you can play without necessarily signing up, you will need to create an account and make your initial deposit if you are looking to play real money slots. However, we would emphasize that you choose a trusted and legal online casino when playing for real money to avoid getting scammed by unscrupulous gambling sites.
Tips on How to Win Playing Online Video Slots
Online video slots are games of chances, and as such, there is no way one can predict/alter the outcome since the results are generated by a random number generator (RNG). However, we have outlined several online video slots strategies to help you choose the best slots with higher winning possibilities.
Choose slots with the highest payout percentage
Most players ignore the importance of a slot’s RTP. Although the payout percentage of a slot is theoretical, it still plays a crucial role in determining how much your investment will return over time. Recommendable slots will have an RTP above 90%, while some of the best slot payouts can go over 95%. As earlier mentioned, with RTP, it is important to consider other factors such as the slot’s volatility. A high variance slot will have huge but less frequent wins, while a low variance slot will offer small but frequent wins.
Play slots with the highest jackpots
If you are determined to win significant amounts playing online slots, then you should give progressive jackpot slots a shot. Although most of these slots will require you to wager on the maximum bet limit, they offer a chance to win huge amounts. However, if you are a beginner or working with a limited budget, this should by no means make you feel pressured.
Implement the strategy of progressive betting
To emphasize the point of not feeling pressured to jump for the big wins, we would highly recommend you start with a popular system known as progressive betting. With this online video slots strategy, you start off with the lowest bet and increase it every 50 spins. If, during these 50 spins, you don’t end up landing free games or significant wins, then it is time to raise the bet per payline. Hence, if you are lucky to land a higher win, it is more likely to be more than enough to compensate for your loss.
