BEST CASINO SLOT GAMES FOR 2023
What the best online slots and what makes a “best online slot”. With so many criteria to choose from, we think the best online slots should be judged on their visual appearance, in game play and keeping players interested and their potential payback.
MONOPOLY Live from Evolution Gaming has taken the market by storm. It’s interesting, it has fantastic graphics, and you can win big when you hit the bonus round. MONOPOLY Live game has a host spinning the super-sized, vertically mounted wheel and, like roulette, players predict the section of the wheel it is going to stop. If the wheel stops on a certain number, the wheel incorporates ‘CHANCE’ segments for cash wins and multipliers. When the multiplier round kicks in an augmented reality, 3D Bonus game triggers and MR. MONOPOLY takes over. Well worth a spin!
Gonzo’s Quest is designed NetEnt who went the extra by creating a short introductory movie to spark your interest. The slot takes you to the Peruvian ruins at the time of the famous conquistador Gonzalo Pizzaro. This online slot has impressive graphics and in-play features and is well worth a spin, especially if you score the “avalanche multipliers” and “free fall” symbols.
Dead or Alive is a Wild West-themed slot featuring a 5 reels x 9 paylines layout. Created by NetEnt, it offers impressive visual and audio effects. Dead or Alive RTP is 96.8% and includes wild, scatter and free spins special features.
We haven’t included Starburst and Twin Spin in our best online slots list because, let’s face it, they are about as interesting as watching grass grow.
BEST PAYOUT SLOTS GAMES IN THE UK
The best payout online slots UK casinos provide are either high RTP slots or high variance online slots. High variance slots are particularly popular with high rollers and serious gamblers because of the potential pay outs they offer. These slots are structured to ensure that they drop money less frequently but have the potential to make you very happy (and rich) when they do. You’ll need plenty of fortitude, as well as deep pockets and the stomach for the challenge.
Variance defines the way that games behave. It refers to the size and relative frequency of the payouts provided by an online slot. Low variance games will pay out more regularly but in lower amounts, while high variance games provide more potential for big wins but may not pay any money for prolonged periods of time. Medium variance games sit somewhere between the two.
Most casual players aren’t particularly bothered about variance at all. In fact, many of them won’t even know what it means, let alone the variance level of a specific slot. However, for those that do, low variance slots may suit. Your money is likely to last longer on these types of games, thus prolonging your gaming session. If you have a limited bank balance, this is likely to work well. For some, however, the large sums of money you can win from a high variance slot define the experience of online casino play. Here is our list of some of the best payout online slots UK casinos have available to play.
Book of Dead
I’ll start with a slot that has achieved quite remarkable success. I’d wager that Play N’ Go, who is responsible for the game, is surprised just how popular Book of Dead has become. I have it on good authority that it’s one of the top 3 or 4 most popular games at some major online casinos, which is remarkable for a slot of its type. The game’s lead character ‘Rich Wilde’ evokes Indiana Jones as he raids tombs in search of lost treasure. It’s the excellent expanding wilds feature and free spins round that will help you chalk up the big wins though.
Dead or Alive
When people talk about high variance games, the name ‘Dead or Alive’ is always likely to figure highly. Often considered the flagship high variance game in Swedish software giant NetEnt’s portfolio, the wild-west-themed game offers some classic features of the genre. Expect long waits between wins but the occasional huge drop. You can earn up to 29 free spins in the bonus round with a x2 multiplier. Apply sticky wilds too, and you can win mammoth amounts – up to £56,000 to be precise. Little wonder Dead or Alive is a legendary online slot.
Yggdrasil Gaming’s Casino Zeppelin is cut from a similar cloth to Dead or Alive – and it is probably the next best thing. Inspired by the huge steam powered balloons of the Victorian era, it’s an attractive slot that offers lively gameplay. As is often the case, the free spins round is responsible for most of the big wins. It’s tricky to trigger, but once you’re in it, you can expect 20 free spins and sticky wilds which stay on the reels for the duration of the bonus game. You can win up to 10,000 coins if you’re lucks in. You’ll need to remain patient during the main game though.
This is another legendary slot that probably falls closer to the medium end of high variance but can provide some eye-popping rewards. Immortal Romance is one of Microgaming’s 243-win ways games so you can appreciate that wins do come along with a degree of frequency. However, it’s the Wild Desire feature that will get your pulse racing. It can turn all five reels into blanket wilds and trigger some massive wins. If you score that run of luck on this vampire-themed slot, however, then you’re on a hell of a lucky bleeder.
This Spartan-themed slot from NextGen has a reputation for being highly volatile and having played it, I can confirm that suspicion. The Battle Bonus game provides you with five free spins and x2 multiplier, which may not seem particularly special at first glance. However, within the free spins round, you can earn more free spins and an increased multiplier when you land shield symbols. Now, allow yourself to dream for a second. If you manage to land 12 shield symbols during the free spins round, you’ll receive a final batch of 5 free rounds, but this type the spins will be subject to a frankly ridiculous x300 multiplier. It’s quite the prize to pursue, but you’re likely to spend a lot of money trying to get to it.
NEW ONLINE SLOTS
The new online slots for 2019 include war-themed slots like Game Of Gladiators, TV series-inspired titles like Narcos and Game Of Thrones or magic and mythology slots such as Fiery Kirin

PROGRESSIVE SLOTS ONLINE
Progressive slots online transfer a fraction of the real money lost on each spin into the jackpot purse. As more players lose the jackpot increases and bigger the jackpot the more players play. Mega Moolah is a classic example of how the jackpot amount suddenly increases above £3million. In order to increase your chances of scoring a progressive jackpot there are few tips that players should consider.
- The first tip when it comes to progressive jackpot slots is that you never should chase the jackpot! Most of you believe that if you play long enough, you will get the jackpot, and you will recover the money you invested, but this usually isn’t the case, and another player gets the entire jackpot. Regardless of how long you have been playing without winning a jackpot, never chase it!
- Bet the Maximum number of Coins. When you play games of this kind, you will always want to bet the maximum amount of coins. This increases the overall winning possibility and also allows you to get possible bonuses. By decreasing the number of coins, you decrease the chance of winning. After all, your primary goal should be winning the maximum jackpot possible
- Check Bonus Terms and Conditions. Each online casino is different, and each one has special terms and conditions. Most of them are related to bonuses, so make sure you read them before you start playing the game. It helps to know all about possible bonuses and eliminates the risk of missing out. Progressive slots are truly special after all. It could look like one of the best casino bonuses in the world but the terms and conditions may mitigate any chance you have of winning real money.
- Wait for the Jackpot to Go Above The Previous Win. When you login to a casino account, you will generally be able to see the previous winners jackpot slots games. Now, you want to wait until that value is increased even more, so it will be higher than the last win. This naturally increases the chance of getting a higher jackpot and also increases the chances of getting jackpot in the first place.
ONLINE SLOTS TIPS
Online slots tips are tricky since most players are hoping for the big win whilst “safe” in the knowledge online casino slots in the long run ALWAYS win for the house. An online slot with high RTP of 97% still means players will lost £3 of every £100 wagered. There are however some tips that can help you, at least physiologically!
- Play for fun. Snooze we hear you say. But before you switch off, online slots main purpose is for entertainment. If you start playing with that in mind you will more likely be able to site back and relax and simply enjoy the game. Relax and play for fun.
- Most slot games have a low bet somewhere around 10p, going all the way up to £100. If you start betting £10 and you only have £100 to play with, you will be able to play only ten rounds. To maximise your enjoyment wager enough to secure a decent win but a the same time make sure you wager no more than 2% of your real money kitty per spin.
- Use bonuses and promotion. There are numerous examples of welcome bonuses, reload bonuses, daily promotions, weekly, seasonal and special promotions offering bonus spins or free spins. All online casinos will offer them at some point, and your main goal is to use each one of them. That’s why you will have to sign up for these promotions, make them your priority and simply enjoy a great time and great advantage each bonus has to offer. Look for the online casino free spins of online casino bonus spins. For more information check out our casino bonuses page
- Choose progressive slot games. Progressive slot games are more appealing due to high jackpots like Mega Moolah. These jackpots can go up to £5million plus and someon ALWAYS wins.
- Pay attention to the win cycle of a slot game. All slot games have win cycle, meaning that they will reward a potential player at that moment. On the other hand, they are mostly in the non-winning cycle, so chances of winning are close to zero. As one of the online slots tips that is rare and most commonly kept as a secret, all players should invest their time in slots that haven’t provided payout for a longer period. By doing so, they have a high chance of starting the winning cycle with that, particular slot game. You will be there when it starts paying money to players. One really goof tip is to keep an eye for high variance slots. These have major downs but the payout can be huge.
