Tips
Offerings From the Best Online Slots Casinos in the UK
The online casino landscape has grown really quickly over the past few years. With that growth, online casinos have invested a lot into the work that software developers are doing to create more titles. Gone are the days where you needed to account for how much space you had on the casino floor and that determines how many games you can have. Here is how online casinos offering online slots can change the way you see slot games.
Secure and Reliable Software
The most trustworthy online casinos will have a great selection of games that are packed with the best software. Software developers like Microgaming, NetEnt, Playtech, Push Gaming and others take their time to produce quality gaming experiences. These have the best graphics and most video slots tell their stories really well. These online slots are sure to function perfectly on your desktop computer or a mobile device of your choice.
Online casinos also ensure the safety of your money and personal information. This is especially true when the online casinos offering online slots have a license from a reputable source and are also regularly audited by companies such as eCOGRA.
Huge Selection of Games
The online casinos we recommend for playing online slots all have hundreds if not thousands of online slots to choose from. Players will find three-reel and multi-reel online slots at these online casinos. The games are made even more exciting when you can find a game you like in a specific genre or theme. We also take our time and find online casinos that offer free to play games as well. You can test out an online slot for free before you commit to depositing real money and placing a bet.
Great Welcome Bonuses
One of the most important things we check for is what the online casinos are offering as a welcome bonus. We want players to have a warm welcome when they choose a site from our list. We want to see free spins, match bonuses that can be used on slots and payout percentages that are 90% or higher. There should be a high chance for the player to win each time they spin the reels.
High-Quality Gaming Experience
The online casinos we review along with the online slots they have on offer, need to fit the criteria above or exceed it. That is the only way for an online casino offering online slots to find its way onto our list of recommended online casinos. When you choose from that list, you can rest assured that you will receive premium quality entertainment that is safe and can be enjoyed through several operating systems. We also come back every few months to ensure that the online casinos are maintaining their standards or exceeding them.
Free Online Slots Vs. Real Money Slots
Free online slots are a great way to kill time and play your favourite online slots without any risks. However, any slot enthusiast will tell you that the thrill comes from taking that risk. Here are some of the pros and cons our team have found about these two versions of the games.
Strategies for Online Slots
It's not realistic to think that there are actual strategies that can be used when playing online slots. These games are governed by Random Number Generators to ensure that they are fair and random at all times. This also ensures that anyone stands a chance to win and all it takes is luck. However, avid online slot players swear that playing games with the highest payout percentages, knowing their paylines and practicing bonus rounds are sure ways to win.
Payout Percentages Explained
When you get used to doing your research about online slots, you will always see experts referencing the payout percentage of a game or the return to player rates (RTP). These figures tell you a lot about your chances of winning and the house edge. If an online slot or slot machine has a payout percentage or RTP of 98%, that means that the operator or casino pays out £98 for every £100 that is bet on the game. We ensure that these figures are clearly displayed for you, so you can decide if it is worth playing the game or not.
Online Slot Software Providers in the UK
There are thousands of online slots at online casinos. However, some of the most impressive gaming features come with video slots. The software developers that create these games do a great job of bringing an exciting gaming experience to life. These software developers are well-known in the industry, but here are some of the developers we think you should look out for when looking for an online slot game to play:

Online Slots in the UK FAQs?
Are there free online slots I can play?
If you are not ready to place real money bets with online casinos playing online slots then there are tons of options available that you can play for free. We check to see that the recommended online casinos in our list all have free to play options when it comes to online slots. You can experience all the fun that an online slot offers without taking any risks.
What should a good online casino have that I should be looking for?
Any reputable online casino that offers online slots should be fully licensed by one of the most reputable online gaming authorities. These include the UK Gambling Commission, the Malta gaming authority or a license from the government of Curacao. You should also be looking for a favourable payout percentage. The higher the payout percentage is, the more you stand to win if you get a winning combination.
Do online slots have real money prizes?
Yes. You can win real money at an online casino the same way you would at a land-based casino with a slot machine.
Are online slots safe?
Yes. This is especially true if you choose an online slots casino from our recommended list of sites. As long as the website is trustworthy then the game itself should be as well.
Are online slots fair?
Yes. These games are not rigged and run on RNGs or random number generators. This is software that ensures that all outcomes are exactly as they would be on a real slot machine. This keeps the game random and the chance of you winning is the same as the next player. To make sure of this, check to see if the online casino is regularly audited by an independent company that ensures the software is performing as it should.
What are progressive jackpot online slots?
These games build up a huge jackpot that is gathered from any winning bet that previous players have had. Sometimes it is a single game on a website or a game that can be played at various websites. The same game is linked through the websites and the jackpot grows faster and higher in no time.
