What are Online Slots and why play them?

Slot games that fit your style

As mentioned earlier, one of our top priorities is to make sure that you find the very best slots out there, and here are some tips on what to look for to help you find the ones that perfectly suit you.

What to pay attention to when choosing a Slot game?

Here are the different things we think it’s important to pay attention to when looking for a slot you’ll enjoy.

1. Theme

Slots have several different themes, and it’s important to choose slots with themes that will guarantee that you have the most fun. Make sure you pick a slot that has a theme that you are interested in.

2. Payouts

Naturally, some players tend to gravitate towards slots with promising payouts. The greater the possibility of a big payout while playing a slot, the better. Check out some of the best payout slots on the market.

3. Risk

As with most things, playing slots does come with its risks. Make sure you are as knowledgeable about the risks involved, and only play if you are able to stand the risks.

4. Look out for volatility

The higher the volatility of a slot is, the bigger the wins. Although it may take time to land wins on slots with higher volatility, the wins tend to be bigger than lower volatility slots.

5. Pay attention to RTP

You should go for the slots that have the highest RTP (Return to Player) rate, as they will likely guide you toward big wins. A slot that has a 96% RTP rate will give you much better payouts than a slot that has a 60% RTP rate, for example.

6. What’s your budget?

Always make sure you’ve set aside enough funds to use on gameplay and that you don’t exceed your initial budget.

Slots are considered to be some of the most popular casino site games, with titles such as Starburst, Gonzo’s Quest, and Book of Dead ranking high on the “most played slots” list

What Types of UK Slots Are Out There?

In addition to the general theme of online casino slots, you can look at its underlying structure.

Most games have five reels. However, those with a classic theme can have three, while new online slots may have six, seven or even more reels.

Therefore, you need to know what’s available and, in turn, find a structure that suits you.

Number of Reels

How many reels can online slots have? Here are some examples of what’s out there.

3-Reel Slots – Fruit Slots

These slots are often described as classics or online fruit machines because they mirror games that were popular in the 70s and 80s.

As well as three reels, these slots will often have between one and five paylines.

5-Reel Slots

Approximately 90% of the UK online slots have five reels.

These games allow for more paylines and features than 3-reel spinners, hence why they form the basis of today’s leading video and progressive jackpot slots.

7-Reel Slots

Developers have got creative in recent years and that’s taken slot gaming technology to new levels.

Thanks to innovations such as Megaways, traditional formats have been enhanced.

Today, you can find games with reels that go all the way up to 7.

Game Type

What type of online slot games can you play? Let’s take a look…

Classic Slots and Fruit Machines

These online slots are designed to look like the traditional slot machines that some of us love so much, featuring the classic fruit symbols along with other symbols like 7s, Bars, and Stars.

Online slot machines tend to be quite straightforward and usually come with a small number of paylines and a simple reel setup.

They may also have various other features like free spins, a gamble feature (the possibility of gambling your winnings for a higher amount), as well as a jackpot.

Video Slots

The best video slots online typically fall into this category.

There isn’t a specific theme or feature you can use to define what a video slot is.

The main characteristic to look out for is “reels”.

3D Slots

3D online slots are a subgenre of classic and video slots online. They’re a subgenre because they feature the main characteristics of classics or video slots but provide a different perspective, literally.

Instead of showing you the reels and nothing else, 3D slots show you the machine in its full glory.

Progressive Jackpot Slots

These online UK slots take a small percentage of everyone’s bets and add them to a communal pot.

That allows the prize pool to grow at an exponential rate, especially since these slots are normally available across multiple casinos. Once someone hits the right combination, they scoop the pot.

This makes progressive jackpot online slots more lucrative than those with fixed payouts.

Developed by premier provider Relax Gaming, Dream Drop is a perfect example of a highly lucrative feature that could lead to exemplary wins! Since its launch in 2022. players who have played slots with the feature have amassed some amazing wins. An example of such a win is the €997,779.17 monster payout on Snake Arena Dream Drop at Videoslots.

Megaways Slots

Megaways is a slot payout mechanic developed by Big Time Gaming.

The system can be applied to existing slots or used to make new online slots.

The main characteristic of a Megaways slot is its random number of ways to win.

Cluster Slots

Traditional online slots have a certain number of paylines across which you need to line up matching symbols.

Cluster slots don’t have paylines. Instead, you need matching symbols to land in clusters i.e. they need to be touching.

Multi-payline

In comparison to regular slots, multi-payline slots increase your chances of winning because they are built to cover more lines than regular slots.

Bonus Buy Slots

Bonus Buy slots give players the option to buy their way into the bonus round instead of having to patiently wait to get there.

Hold and Win Slots

Hold and Win slots are a pretty new creation. With these come an abundance of re-spins, which naturally would lead to higher chances of winning.

Did you know?
Apollo Pays has an inbuilt Hold and Win feature and is one of the most popular Hold and Win slots in the UK.

How to increase your chances of winning while playing slots?

Time to focus on why you’re really here: how to win online slots!

There are certain games where skill has a place at the table.

For example, an understanding of mathematics can help you reduce the house edge in Blackjack.

When it comes to how to win online slots, there isn’t a lot you can do. Because the result of a spin is random, you can’t increase your chances of winning.

What you can do, however, is control things before you spin.

By making the right choices, it’s possible to enhance your overall experience and get the most from a game.
