With studios easily bringing a few titles out every month, the portfolio of available games has been growing quickly. It’s alright to feel a little overwhelmed at first. However, we will help find your feet in this colourful cacophony that provides you with one excellent choice after the other.

Having said this, it’s time to actually make our choice, and usually there are two ways how to go about this. On the one hand, you can stick with the new and exclusive titles or you can simply listen to what classics we recommend. Of course, we will consider the freshly-minted titles, too!

In a world where gamers have grown quite sophisticated in their preferences and tastes, the games pay-outs have inched up as well.

Our overview will provide you with a simple and yet well-research explanation to help you pick the best online slots. We’ll go a step further, though. Quite the slot-lovers ourselves, we will provide you with a detailed breakdown of how slots work and what makes them absolutely worth your while. We’ll still explore the few caveats that you need to bear in mind, though. And if you need a reliable examination of a particular title, you can rest assured that we have reviewed it already ourselves and you can scoop up the facts you care about at a glance!

A Sweet Variety of Creative Gaming Options

To be perfectly honest, finding the best online slots can be a bit of a tall order. There’re just too many good titles that we wholeheartedly recommend, but when it comes to perfect choices, we will definitely draw your attention only to the titles that we personally would choose for ourselves, letting you know about a few extra titles that are still great picks!

And yet here’s the thing – we are suckers for space exploration, but you may be a gamer who enjoys Ancient Egypt and the enigma of deities of yore more so than the glitz and glamor of modern-day wrap-speed spaceships. Thankfully, there are pre-determined criteria we can use to decide whether a slot is worth your while, and specifically:

  • Who’s the developer?
  • What is the Return-To-Player rate?

Reputation has always been important. Only with video slots, when you name the software provider you immediately can get a reliable gauge of what to expect, although it’s not unusual for the house names to surprise us with an innovative twist here and a bold move there.

As a matter of fact, the variety hardly begins with the developer. Many of the slots today are differentiated into several categories, for instance:

  • Fruit Machines
  • 3 & 5 Reel Slots
  • I-Slots
  • 3D Slots
  • Featured Slots
  • Video Slots
  • Progressive Jackpots

While there is a fairly good explanation about every single type of slot variation, you will notice that these days, they all boldly borrow elements from one another and prefer to pluck the best features quite unabashedly to deliver an unrivalled final solution.

Thus, an I-Slot is a game that focuses on the player, allowing them to make personalized choice that influence the outcome of the game. But this can as well be called a Featured Slot where Wilds and Scatter Symbols introduce you to bonus levels.

Progressive Jackpots may deserve a specific mention, though. True, they do borrow elements from other titles, but the most dazzling trait of these games is that they allow you to play for the big money!

Progressive Jackpots – It’s Where the Big Money Is

Progressive Jackpots are title like any other. They only tend to run secret bonus levels, which are a mean feat to access, but once you do, you have a shot at the dazzling jackpot. And let’s face it, playing for the big jackpot is definitely a seductive prospect.

You would wonder, what is a jackpot and do the best online slots come along with a tidy prize pool to be won? Well, the answer is yes – progressive jackpot games are a network affair. Put simply, you take a crack at the pot and so do thousands of others. Every loss is not really a loss – it’s a titbit that helps the pot grow.

Prize pools worth £2,000,000 are in fact quite common and amassing North of £5,000,000 is really not unheard of. Want a chance at the pot? You may want to pick a suitable title first!

Software – What Makes the Slots Chug Along!

The professionals who have devoted their time and effort to bring you a streamlined title have also ensured that the underpinning platforms that makes the experience possible is up to the latest benchmarks for excellence. In our long career of testing reviews, we haven’t really had an incident where a slot was performing poorly.

Perhaps only at the dawn of the mobile compatibility age, when certain games would have a bit of a shabby gameplay when accessed on a portable device, such as a smartphone.

Brilliant mobile-compatibility thanks to HTML5.
Improved security & impeccable gameplay.
Consistency across all devices used to play from.
Excellent personalisation options
Ability to adjust your stake with the one that works best for you

A yet another problem back then was the lack of mobile compatibility between iOS-powered devices and gaming products. But the software that is used today quickly solves this issue out. Infused with HTML5, the cutting-edge platforms of today bring the full variety of slots to all of your gizmos and the experience isn’t diminished in the slightest.

Oh, and better yet! Older titles are gradually ported to the new engine, although, we will have to admit it – some may be lost in the great trek between ages.

The Names of the Studios That Bring Us Joy

Many and varied, you must by now know the names of at least a handful studios. NetEnt are one of the brands that are quite successful thanks to their innovative and player-focused approach. They have a dedicated social media channel and their websites is built on minimalistic design to help readers focus on the information. They are also authors of some of the most notable gaming products out there. NetEnt are in the habit of adapting movies for slots and re-creating tales into full-blown iGaming experience.

Don’t go thinking that NetEnt the sole trail-blazers here, though. Microgaming are famed for their Quickfire Gaming platform which has brought us memorable titles of their own, including Avalon, Thunderstruck and Terminator franchises.

Playtech and Evolution gaming meanwhile have also made their contributions to the slot genre, but they hold the title of the most accomplished live games creators. You can see their excellence into that area seep through their slots, too!

Reading the Best Online Slots and their Features

And so, borrowing is no longer a crime in the world of mad spins. The games share a variety of elements that they have poached from one another way in the past, with all the great features finding an awesome staying power to shape how we experience the titles today. Still, it may be worth making a mention of three of the main aspects involved in each modern slot game, so as to help you understand them a wee bit better:

  • Wild – The Wild is the single most desired symbol out there. It will readily replace any symbol out there and help you complete virtually every payline! Mind, though, because as awesome as a Wild is, it cannot sub for a Scatter.
  • Scatter – The Scatter is a multi-purpose symbol that promises to finish off a winning combination, or better yet – throw a few extra spins for you. Not only that, but Scatters can also trigger a bonus level, provided the game comes with one, and quickly help you expand your bankroll.
  • Multipliers – It’s what the name says – a multiplier. Your winnings will be upped by a specific amount of times and you will quickly turn any sum into a rather substantial reward.

While these may be the basic sort of symbols you will find out there, there is a variety of spin-offs that can serve as a mix between any of the two. In addition, you can come across multiple scatters and wilds. Slots have progressed to make the gameplay quite different from what you may be accustomed to.

You will be out there hunting power runes, gems and energy to trigger a multiplier feature or to open up a bonus level, which will be adjusted depending of what resource you have been able to amass the most of.

Lastly, you will notice that there is a place for the common symbols, too! Symbols will too have a value that will vary depending on what you end up with on the paylines. There’s an easy way to check with most excellent slots, though. Simply refer to the paytable.

Playing the Slots – A Smart Choice After All!

If you opt for the slots, you will stand to benefit from products that have been streamlined to perfection. Turning a profit will be your driving force and key motivator whereas the prospect of hitting the life-changing jackpot will be your ultimate goal.
