Top 10 Best Online Slots

Different Types of Slots

There are tons of different sorts of slots – whether a video slot, a themed slot based on a franchise, or a slot with brand new mechanics (like megaways), there’s always something new. In addition to regular desktop online games, mobile online casinos are also being prioritised as many players want to play on the go, whenever and wherever they want. There is a huge variety of slot games to play on top slots sites and players have the option to play for fun or play games for real money.

Choosing the Best Online Slot Sites

Look for some quality standards such as 24/7 customer support, live chat support and great software providers if you are playing at a real money casino. Although the selection of slot games is ever increasing, the best online casino software provider is what sets one casino slot apart from another.

Some experienced players target the games of the software providers that they enjoy most, while others may prefer to try virtually all slots online in one place. Luckily, there are plenty to choose from.

The biggest and best online slots makers include Microgaming, Playtech and Netent. All of these casino software companies offer more than 100 cutting-edge slots games and add new ones on a monthly basis.

Playing in a casino that offers top class slots games can be really fun, whether you try a few free slots from various software providers before you are ready to play slot games for real money or just jump straight in. You can play free slots online provided by a variety of different software suppliers at the free slots section of our website, with no registration or download required!

Best Online Slot Bonuses

Some slot focused casinos will design offers based solely on online slots and give players a selection of slots to choose from. In this section, we’ll be delving into the top casino promotions which are targeted to online slot enthusiasts. Keep in mind these bonuses won't be available to be played with every casino game. We recommend you read the terms and conditions of each promotion before playing:

• Free Spins Bonuses;
• No Deposit Free Spins;
• Welcome Spins.

Free Spins Bonuses

As the name suggests, these types of promotions are catered for online slot lovers. The number of free spins awarded in the welcome bonus tends to be generous, especially when combined with a deposit bonus. These free spins are usually able to be played on one particular popular slot.

The casino will specify which online slot is eligible for their promotion and in some cases, you’ll have the liberty to choose from a number of top online slots. Be sure to visit the terms and conditions first, as from there you’ll discover the wagering requirements and any capped winnings from your free spins.

Very often, the free spins bonuses, are valid on a bunch of slot games. The most common are: Book of Dead (Play'n GO), Gonzo's Quest (Netent), Starburst (Netent), Wolf Gold (Pragmatic Play), Reactoonz (Play'n GO), Cleopatra (IGT), Book of Ra (Novomatic), Immortal Romance (Microgaming), Big Bass Bonanza (Reel Kingdom), Rainbow Riches (Barcrest), Bonanza Megaways (BTG), 9 Pots of Gold (Gameburger Studios) and Eye of Horus (Red Tiger Gaming).

No Deposit Free Spins

No deposit bonuses are some of the most sought after bonuses by casino players, for obvious reasons. The online casino bonus rewards players just for opening an account as a token of appreciation for choosing them.

No deposit free spins are probably the most preferred casino promotions relating to online slot enthusiasts. Players feel at ease knowing the fact that they're able to spin the reels without having to commit any funds.

All you need to do to qualify for a no deposit free spins bonus is register with the online casino as a new player and you instantly be rewarded with your free spins. The terms and conditions will list the online slot games available to use the free spins on, so be sure to read through them before you accept the bonus as this means you will be fully aware of any wagering requirements.

Like every free cash casino bonus on the market, even the no deposit free spins have some conditions to meet before the withdrawal.

Welcome Spins

Differing from a regular welcome bonus, Welcome Spins to be a bit more generous than a regular welcome bonus, as they are dedicated just to spins. For instance, some online casinos offer free spins on all NetEnt games in their free spins package while others will only have a couple of games to choose from.

Some of the best-known names making their way in free spins bonuses include Starburst, Blood Suckers, Dead or Alive, Rich Wilde And The Book of The Dead. 

Welcome spins are a perfect way for newbie players to get used to the mechanics of an online slot and an opportunity to get familiar with pay tables, game symbols and pay lines. This will make playing slots online a much better experience for any new players!

Best Online Slot Features

Slots come with all sorts of bonus features – from a classic three-reel game that you’d recognise from an antique game, up to a state of the art video slot with extra mechanics, there are so many ways to win and play. Here are the best slot features that you’ll find in the online casino world.

Jackpots

Jackpots have been around since the brick and mortar casinos, making it a highly volatile yet rewarding feature. By having a bunch of slot machines lined up together, the collective losses will be pooled together into a communal jackpot, making one lucky player very happy once the jackpot hit! Most online casinos offer progressive jackpot slots, and often the jackpot is put together by players across multiple casinos – making for huge winnings!

There are different types of jackpots you can find when playing online slots; these are local jackpots, network jackpots, fixed jackpots and progressive jackpots. The best one for winnings is the progressive jackpots, which could reach a huge amount of money. Here are the best jackpot slots so far:

• Megabucks;
• Mega Moolah;
• Mega Dreams.

Wilds Symbols

Wild symbols can really switch up your game - with a wild symbol able to replace any other symbol in play, they can line up combinations that you would not have gotten otherwise! When lining up your symbols on the reels, wild symbols can either let other symbols work together for set wins or trigger their own special rounds, depending on the rules of the game. Here are the best slot games with wilds:

• Starburst;
• Mustang Money;
• Gemix.

Scatters Symbols

Scatter pay symbols payout winnings no matter how they land on the reels. These make for exciting gameplay, with potential wins all over the game, and when combined with other symbols they can make for huge wins. Our top picks with scatter symbols:

• Kitty Glitter;
• Sticky Bandits;
• Caishen's Gold.

Cluster Symbols

Cluster symbols follow the rule that together is better – and in their case it’s true! Cluster symbols will join up with one another when you line them up near each other in a slot, no matter where on the reels they are. With these, you have hundreds of more ways to win when you spin. Here are the top cluster symbols slots:

• Energoonz;
• Aloha Cluster Pays;
• Jammin Jars.

Colossal Symbols

You can’t miss colossal symbols, as they fly past you on the reel you’ll notice they’re quite a bit larger than your normal slot symbol. Colossal symbols will occupy a larger space on a reel, sometimes taking up a 2x2, 3x3 or even 4x4 amount of space. They increase your likelihood of winning on that spin, as they have plenty more opportunities to line up with other symbols on the reels! Let's see the top games with colossal symbols:

• Tahiti Gold;
• Big Blox;
• Spinata Grande.

Stacked Symbols

Stacked symbols are when the symbols on your slot reels are on top of one another. Sometimes they’ll take up an entire reel when you play, and increase the potential you have of lining up similar symbols across the reels. If you manage to fill multiple reels with the symbols, you can activate as many as every single available pay line on the slot! Some of our favourite games with stacked symbols are:

• Golden Goddess;
• Copy Cats;
• Wings of the Phoenix.

Bonus Games

Bonus games bring a secret extra twist to your favourite slots. In some cases, you’ll spin symbols that trigger an extra round or a new gameplay mode. For example, a bonus round might be triggered with the right symbols that multiply your win, or which gives you a certain number of free spins to add to your total. The game we play with bonus games are:

• Book of Dead;
• Where's the Gold;
• Kings Ramses Triple Shot.

Expanding Reels

You might think that the number of reels in a slot is set in stone – but that’s not the case! A slot with expanding reels will add a whole new reel – or two – allowing you to maximise your pay lines when you spin. Usually, this change is triggered by the right combination of the bonus symbols, meaning that on this spin or for the specified number, you get more opportunities to match those symbols and win big. Try this feature on these top slots:

• Flux;
• Dwarf Mine;
• Monopoly Heights.

Free Spins

Free Spins allow players to give their slot game an extra level of fun without needing to spend any more money. Trigger free spins round and you’ll be treated to a certain number of spins on the game, sometimes in a special bonus round that is added onto your current spin. What’s more is anything you win in the free spins round gets added to your win total, no matter your initial stake. Here are the best casino slots with free spins:

• Kronos;
• Fortunes of Sparta;
• Samurai Split.

Respins Galore

Respins allow you to change the outcome of your current game – just a little bit! When you make a spin on a slot, your reels will settle and perhaps you’ll be a winner, or maybe not. Or, maybe your reels nearly line up but not quite! You can use a respin to spin just one reel at a time for your initial bet. As a result, your new spin might drop the symbols where you want them, making your initial spin a winner. The best respins online slots are:

• Book of Oz;
• White Rabbit;
• Pirate Gold.

Nudges

Nudges aim to give you a little opportunity to wiggle the reels a bit. Perhaps your current spin didn’t quite work out for you, but the nudge option means you can kick the reels up or down a little. You can usually hold a certain number of reels, and then move the symbols by one or two positions on the others. Sometimes it’s just the little push needed to ensure the win! Let's see some games with nudges:

• Trojan Tales;
• Age of Pirates;
• Mine of Riches.

Reel Modifiers

A reel modifier is a bonus round that’s triggered by either a random event or by a selection of modifier symbols. They tend to change the way your reel works in the game – for example, perhaps it sends a special symbol for one round that you can line up for a big win, or it announces that you’ll have a guaranteed win. Sometimes it will potentially cause a normal bonus spin which you might not have had before. The top reel modifier slots are:

• The Goonies;
• Ted;
• Beavis and Butthead.

Gamble Feature

Slots are already an exciting game with the outcome dependent on your luck with the reels. But what if you could make it even more exciting? Gamble features tend to let you make a bet on your winnings – spin the right combo, or flip a coin on the correct side, and you can increase your winnings. Often if you don’t make the right one, you can lose your winnings that round, however – so be sure before you choose this! Let's see where to play the gamble feature at its best:

• Book of Ra Deluxe;
• 88 Riches;
• Golden Dragon.

Turbo Spin

Turbo spins let your game go faster – perhaps you’re in limited time to play but you want to get your money’s worth, or you’ve just decided to don’t want to sit around for the animations! Turbo spins can be set for a certain number of spins, and then the game does all the hard work for you, spinning the reels faster than usual. You get to the part you like the most – the winning – without needing to change your bets or click the reels at all! Some games with Turbo Spin are:

• Eastern Emeralds;
• Contact;
• Divine Fortune.

How Online Slots Work

There are plenty of parts that make up a slot game - these are the most important parts of a slot game and what makes it tick.

Coins 

Coins are used to place your stakes on the slot machine you’re playing on. The coin size determines the value of your stake and how much you win the payout. The higher the coin size you place on your stake, the higher your payout will be. Most games will give you the option to switch between currency and coins.

Volatility

Volatility is usually stated within the review of the slot game when you check its instructions. The higher the volatility, the more the symbols will change on the reels and the higher the payout will be once the player does manage to land a winning combination on the reels. The lower the volatility on a slot, the more frequent the wins and stability of the symbols are, but the less the player will get paid out.

Return to Player (RTP)

The RTP percentage, or Return to Player, is the amount over an unlimited amount of time that a player can expect to get back when playing a slot. The RTP will always be stated before playing the slot game. RTP can range from anywhere between 90% to 98%.

Paylines on Slots

Paylines are the winning combination that can be made on a slot machine by lining up or matching symbols. There can be a few or there can be as many as over a thousand – it depends on the developer and the game mechanics.

Maximum Winning

This is the maximum amount the best online casino slots will pay if the best combination appears on the reels with the maximum bet. It's not easy to hit the maximum winning of a game, but many players managed to reach the target successfully. The first rule is to find the games with the highest maximum winning.

Hit Frequency

Not many players know the hit frequency of online slots. When it comes to this value, we are referring to how often a winning combination is formed as opposed to a losing game. It's not easy to find this information when it comes to online slots, and many providers will limit to provide RTP and volatility.

Ways to Win in The Best Slots

There are several Ways To Win features, one being specific to one game provider. These are ways of lining up symbols in the reels which can lead to more wins for the player.

Win Both Ways

As the name suggests: this feature allows the player to strike up matching combinations using both ways on the reels. Whereas normally players are only able to utilise combinations made from left to right on the reels, the Win Both Ways features goes from right to left as well, increasing win chances. Here are the 3 best win-both-ways-slots:

• Crazy Chameleons;
• Cyrus the Virus;
• Siberian Storm.

243 Ways to Win

The 243 Ways To Win was the first one of the features to be developed and implemented on online slot machines. Like the name gives it away: popular slot machines with these features allow the player to land a winning combination in up to 243 different ways, increasing chances to win and landing a higher payout as well. This extended the classic left-to-right formula that was around on slot games in years prior.

• Immortal Romance;
• Thunderstruck II;
• Jurassic Park.

1024 Ways to Win

A massive upgrade from the original 243 Ways To Win feature. 1024 is always played on a slot machine with 5 or more reels, making it possible to combine different symbols into this huge amount of winning paylines. Common on most online slots, you shouldn’t have any difficulty finding a game that offers you these options.

• Crown of Egypt;
• Double Buffalo Spirit;
• Lucky Panda.

Megaways Feature

 Perhaps the crème-de-la-crème of the Ways to Win features. This slot technology has been developed by the software provider Red Tiger Gaming and adds an additional reel on the slot, making for huge potential wins. This feature is limited to specific games right now, but more are popping up as time goes on.

• The Dog House;
• Queen of Riches;
• 5 Lions.

Other Benefits of the TOP Slots

Some more benefits of playing at real money online slots are, that unlike card games or table games in general, where you may go through multiple rounds before obtaining a good hand or play, slots can provide you with a win from a single spin. That’s a highly appealing prospect for many gamers, as you can bet the minimum on a spin and receive a payout for a winning combination occurring in the game.

 Slot games are known for having exciting themes and gameplay running through them, but there’s also the possibility of winning huge jackpot payouts, too. Jackpot slots are favoured by many players because of this prospect. Imagine placing a minimal wager and receiving thousands in a jackpot pay-out after just a few spins – it’s rare but it does happen!

Strategy for Top Real Money Slots

Once you’ve made yourself comfortable with online slots, perhaps you’ll want to try and incorporate some sort of strategy into your gameplay, too. Of course, there’s not much that can be done to really influence the outcome of a spin on a slot. However, you can minimise your losses and get to grips with managing your money by remembering certain tips and putting them into effect.

As noted earlier, playing slot games isn’t the same as playing blackjack or baccarat for example, where different plays can be used. Instead, games in this category are created with a random number generator (RNG) that controls the fairness of the slot. This means that every spin has a randomly decided outcome when you hit the button to start the game.

Check out what the pay-outs for each symbol combination are. See what sort of bets you’re able to place when playing it. Look into the way(s) that you can trigger the different special features of the slot. The more you know about your chosen slot game(s), the better your chances are of remembering what’s going on when you play it.

Tailor Your Bankroll

Furthermore, if you know the betting range on offer, chances are that you’ll be able to tailor your bankroll more effectively.

A couple of final things to remember to take a look at are the RTP rate and the volatility level of the game you’re playing. These can dictate to you how often you can expect to win and the strength of the pay-out you can expect to receive.

If you start out with smaller bets, you can discover more about how the game operates and you’re not risking too much of your balance at the same time. You need to be playing with funds that you can’t afford to lose in the first place anyway, but starting out by placing the minimal bets will allow you to better get to grips with how the slot works and how often the features will trigger.

Try some out in free play demo mode first, then choose one or two that speak to you more.

Final Thoughts

Should you play or not the best online slots? Well, we could debate this for ages without finding a proper answer. It's all about the player and very personal. Some people don't like playing mainstream slots games, while other love it. Here are some pros and cons of playing these slots; we hope you can find your own conclusion.
