Welcome at the Best Slot Sites in the UK for 2022

Today, there is massive competition among online casinos. All these operators want the most significant chunk of players on their website and do everything possible to reel them in. Some do this by offering the best online slots, while others use amazing bonuses, and others can go as far as letting players play for free.

These are only a few tactics used to reel in players, and these can be confusing.  This is because some UK slot sites do it only to lure players in and go back to their default setting when players have registered. Fortunately, we, at Slot Sites UK, do things differently. We offer a collection of the best slot games, amazing 24/7 customer support, numerous payment options, and unique promotions that players can benefit from every week, not just when they first sign up (Ts & Cs Apply).

Types of Games Available at the Best Slot Sites

Because of how popular online slots are among players, there have been many variations created today. It is imperative to understand each of them, so you know the right one for you. Some of the common variants you will find in the best UK slot sites include:

Classic Slots:

These are also referred to as 3-reel slots, and they have existed since 1899 in land-based casinos. The online variant of this game keeps the classic look and feel of the game. It typically comes with 3-reels and some symbols. This is an ideal option for players who want to play fast games or games without complexities on UK slot sites. Some popular classic slots in online casinos include Break Da Bank and Super Nudge 6000.

5-Reel Slots:

These slot games are share lots of similarities with the classic slots. They are also prevalent among players in most slots site. However, they have more reels, paylines, along with improved sounds, graphics, and visuals. Many players enjoy playing these slots on UK slot sites because they are easy to understand, like the classic slots, but give more chances of winning because of the additional reels and paylines. Games with 5 reels include Thunderstruck and Wild Panda.

Video slots:

Video slots are different from the typical classic slots. These slots place a massive emphasis on modern gameplay instead of the simplicity of the classic slots. Most online slots today belong to the category of Video slots, and they typically come in 5-reels, but you will find others having up to 30 or more. In addition to immersive gameplay, Video slots tend to have fantastic bonus features, wilds and scatter symbols that make slots highly entertaining. Great examples of video slots include Starburst and Gonzo’s Quest.

3D Slot Games:

3D slot games are like video slots in terms of bonus features, wilds, and scatters. However, slots in this category make games more interactive using sound effects and life-like animations aligned with the game theme. They also come with unique storylines that tend to keep players occupied.  If you love games that offer interaction, then these slots are right for you. Popular 3D slots you will find on any top slot site include titles like Robin Hood and Marvel Slots.

Progressive Jackpot Slots:

Slot games typically come with a fixed jackpot prize that players will win during gameplay. However, progressive jackpot slots do things differently since the jackpot prize is not fixed. Here, the price increases gradually as any player plays the slot game in any online casino. This works because progressive jackpot slots are linked via a network which means as any players wagers, a part of it is deducted and added to the jackpot prize. Once a player wins the jackpot, the counter resets and begins from scratch. Progressive jackpot slots offer the largest payouts to players in UK slot sites running into millions. Popular progressive jackpot slot games you will find on any leading slot site include Mega Fortune and Mega Moolah which currently holds the record for the largest payout ever.

Branded Slots:

These are slot games linked to game shows, movies, sports teams, music, and other popular brands. Games in this category come with better graphics since they have a successful brand behind them. They are ideal for players loyal to specific brands and want to play a slot game relating to these brands on a slot site. Common branded slots you will find on any top slot site include Ted and The Dark Knight.

We offer all these slot variants on Slot Sites UK. Register today and make your pick from the tons of options available.

How to Play Online Slot Machines

Online slots work in a simple manner. When you want to play slots online, all you need to do is place your desired bet amount, spin the reels, and hope you land a winning combination. Simple right?  Well, not really. Online slots consist of many important aspects that make them work. To get the best chances when playing online slots on online slot sites, you need to understand these parts and what they do. Here are the most important:

Reels: These are the columns that consist of symbols or Icons. Reels come in an average of 3-5 but could be more in most cases.

Paylines: This is the pattern on the reels that determine if you get paid. It is usually predetermined, and landing the right number of winning combinations triggers a win. Paylines tend to differ and range from 1- 100 or more, depending on the game. Other slot games with multi-payline features could have as high as 117,000 winning ways.

Wager/Bet: Before you can spin the reels on a slot, you will first be required to place a bet. Every slot game allows different minimum and maximum wagers, which you need to understand before you play.

RTP: This is also known as the Return to Player, and it is crucial when choosing a slot game. It is the number that shows the total amount that comes back to players in slots through prizes. This number is written in percentage and ranges from 88% -99%. To get the best result, you need to go with slot games with an RTP of 96% or more.

Volatility: This is the level of risk attached to a slot game. This could range from low, medium, or high volatility. Low volatility slots have low risks, while high volatility slots have higher risks. But it is also important to note that the higher the volatility, the higher the prize attached.

Online Slots Bonuses & Special Features

To ensure slot games remain entertaining for players, software providers incorporate many special features to make them fun. Here are a few of the features you will commonly find in online slots when playing on the best slot sites:

Wilds: This feature replaces any standard symbol in the game to help complete a winning combination. Wilds could come in various forms, including cascading wilds, sticky wilds, stacked wilds, etc. This is usually dependent on the slot game you play, but they all serve the purpose of boosting your wins when you play slots online.

Scatters: This is a special symbol that can trigger a win, bonus game, or free spins. However, you will need to fulfill special conditions for it to work, and these differ depending on the slot game. In most slot games, you will need to land 3 scatters or more to get the associated rewards.

Multiplier: This is a special feature that helps boost your winnings by a specified amount. Multipliers range from 2x to as much as 500x or more!

Free Spins: This feature allows you to spin the reels for free on a slot site just as the name suggests. You can trigger it during the base game or when you land the required number of scatter symbols. In most cases, the free spins come with multipliers and wild symbols, all of which help boost your wins.

Gamble Feature: There are slot games that come incorporated with a gamble feature. This feature offers you the opportunity to double or quadruple your win. However, if you lose, it might affect your entire winnings.
