Why play online Slots?
The online arena takes you away from queues and crowds, away from time and geographical restrictions. You can play as you wish, whenever and wherever is most convenient.
Slots are increasingly exciting with advancing technology and excellent graphics to make for engaging, atmospheric gameplay.
You can make the most of the aesthetics on the big screen of your desktop or laptop in the comfort of your own home, or, thanks to mobile optimisation, you can enjoy the experience while you’re out and about on mobile and tablet devices.
How to choose the Best Slots Sites?
The multitude of slots sites out there can seem daunting. However, it need not be, so long as you know what to look for. There are various features that will give you a successful and entertaining experience when you play online slots.
Here we break down the key considerations so that you can select the best online slots for you to enjoy whenever you wish.
Casino License to Accept Slots Players
Before you sign up to any casino or betting site, check the casino’s license. A casino will be required to have a license from the UK Gambling Commission to accept UK casino players, whereas most European casinos will be licensed by one of the following entities:
The casino will normally state who they are licensed by at the bottom of their site. Therefore, you can check the license of any online casino by scrolling to the bottom of their site.
Free Play Slots
Many sites offer the chance to play demo online slots where no cash is exchanged. Free slots and demos are a great way to get a feel for the game, before playing for real money. In other words, free demo slots allow players to experience the gameplay and to find a slot they want to play for real money at an online casino
New Player & Loyalty Offers
The UK slots market is hugely competitive and slots sites must work harder and harder to stand out from the crowd and attract you to play their games. One way in which they attract new players is through new player casino bonuses.
For instance, many slots sites will offer a free spins bonus or no deposit bonus as a way for players to try their casino platform before depositing real money. When an online casino runs a promotion like this it is a good sign, because it shows how confident they are in their games library and casino product overall.
However, you must look beyond just the eye grabbing sign-up offer and also look at their existing customer promotions. Many of the best UK slots sites will offer regular promotions to maximise their customer’s playing experience. For example, they might offer regular bonus spins on selected games, which is great if it includes your favourite games!
Additionally, an online casino might run a VIP club or loyalty program, both of which reward players who regularly play online slots with them. If you regularly play slot games then a strong rewards program is essential, because your play will be recognised.
Mobile Casino Slots
Slots and casino games are increasingly optimised for mobile and tablet so you’re not tied to a desktop or laptop. In a world where the smartphone reigns supreme, more and more players favour playing casino games and slots on mobile. As a result, the best online casinos are continuously optimising their mobile slot games to keep up with playing habits.
Although, the optimisation might differ depending on the site. For instance, some will have developed a mobile app so that players can gain quick access to their favourite casino games and mobile slots.
However, some players may not want to use up their phone storage with a casino app. Therefore, fully optimised mobile sites will be preferable to them.
If you are intending on taking the game on the go with you, check the options for playing your chosen slot on your other devices to ensure you’re covered.
Payment Methods at Slots Sites
You’ll have a huge selection of banking options at the top slots sites. Each deposit method carries different limits. There are also benefits and drawbacks to every deposit option you choose.
Before you choose the method you want to deposit with, first think about how often you will use it. Are there any fees attached to your chosen banking option, and can you qualify for a welcome bonus if you use it?
We always recommend checking the cashier page before you make a first deposit, because there you’ll find a full list of daily deposit limits, as well as withdrawal times.
Remember that most online casinos will apply a processing period to your withdrawal, which allows the casino to perform any additional checks. Plus, you will have the option of reversing the withdrawal request. Always factor in 1-2 days extra, on top of the regular withdrawal time.
Debit Cards
Withdrawal times: 3-5 business days
A debit card like VISA, Maestro and Mastercard is one of the easiest ways to get money in and out of your slots account. You can make instant deposits or request cash-outs that typically take 3-5 days to clear.
All you need to do is register the debit card with your slots site when you open your account. You’ll need to enter some key information when you make a deposit:
-
- Long number on the front
-
- Expiry date
-
- 3-digit security code
Deposit limits can be generous with debit cards. You’ll usually be allowed to deposit anywhere from £10-£10,000 at a time, but slots sites vary.
Also bear in mind that when you withdraw money, you’ll have to cash out to the debit card used to make your original deposit.
e-Wallets
Withdrawal times: 1-2 days
An e-Wallet is a virtual account that can store cash from multiple sources, all in one place. You never have to share card details with the slots site when you make an e-Wallet transfer. All you need is a single e-Wallet email address or ID.
To make an e-Wallet payment, you’ll need to open a virtual wallet account. There are several leading providers who are widely accepted at online slots sites:
-
- Skrill
-
- NETELLER
Once you have opened your e-Wallet account, you can select the method when you access the cashier. Enter the amount you want to deposit, plus your slot site password. You’ll then be redirected to the e-Wallet website to complete the transaction.
The beauty of e-Wallets is that payments are super-quick and totally anonymous. You can also make fast withdrawals back to your e-Wallet within a day or two.
Prepaid Cards
Withdrawal times: 1-3 business days
Some online slots sites accept payment by prepaid card. Prepaid cards are a great option at gambling sites that normally reject traditional debit or credit cards.
A prepaid card is a little like a debit card which can be loaded up with funds from an alternative source. You then make a simple deposit at the online casino by choosing the Visa or Mastercard option. Some slots sites also issue their own prepaid cards.
Alternatively, you can make a deposit via prepaid voucher. For example, paysafecard is free to use and you can deposit as little as £5 in one go.
Just purchase your paysafecard online, then use the unique card number to make a one-off payment. You never have to save debit/credit card details
Types of Slots
Slots come in various formats and styles, dishing up something for every player. Let’s take a look at some of the common types of slots in the e-gaming arena.
Video Slot Offerings
These account for the majority of online slots and are hugely popular with players for their more regular, albeit often lower, payouts, bonus features, ample paylines and exciting themes.
Progressive Jackpots
Progressive slots are becoming ever more engaging in style and playability, dishing up a progressively growing jackpot by taking a small slice of every wager.
The perk here is that payouts are often very substantial and extremely tempting.
The Slot Classics
Fans of simpler gameplay will enjoy classic slots that have a standard, often retro casino feel to them, rather more straightforward playability and a mixture of variance options from low to high.
New Slots Sites vs Traditional Slots Sites
There are thousands of online slots sites to choose from in 2021. But which do you choose? Do you trust the established online casinos with lots of awards and player reviews or go for the shiny, new site that launched 5 minutes ago?
There are pros and cons to choosing new slots sites. But as with all types of online gambling, it’s important to read our site reviews and open multiple accounts first. Give the games a play for free and get a feel for the lobby. Also check the terms and conditions to ensure the bonuses are fair and transparent.
Pros of New Slot Sites
New slots casinos are appearing all the time. Some are sister sites of existing casinos while others are totally new to the industry.
As long as the slots site carries a legitimate license and can prove its games are fair, you know you’re in good hands.
In addition, the newest online slot sites will normally offer a lot of games, some of which may be exclusive to the site. You’ll also be offered a very generous welcome bonus when you sign up. These are common at new slots sites as they compete for fresh customers.
Finally, you should get access to the latest browser-based software and mobile app. Enjoy customizable lobbies and earn achievements every time you play games.
Cons of New Slot Sites
Just because a new slots site is fresh to market, doesn’t mean it’s reliable. It can be hard to know how good a site is if it’s just launched. It hasn’t had time to win awards or build up trust among customers.
Therefore, we always recommend checking a few details before you start playing slots:
-
- Where is the casino licensed?
-
- Who owns and operates the site?
-
- Which major software providers does it carry?
-
- Can you play on mobile and desktop?
-
- Are there any fees for making deposits and withdrawals?
If a solid operator already has a good reputation with one of its other slots sites, you can usually rely on the new addition. Also look out for evidence of independent audits.
All online gambling casinos should independently test their software and games for fairness. Approved testing bodies like GLi and eCOGRA have years of experience auditing online slots to ensure their random number generators are working properly.
Slots Sites with Casino Games
Online casinos tend to be divided into two camps: those that carry just online slots, and casinos that offer a range of table games too.
The best casino sites will offer a healthy mix of online slots, plus traditional table games like roulette and blackjack. You can try out games for free first before committing your bankroll. Simply click on the ‘demo play’ or ‘practice play’ buttons to open games in your browser.
Casinos also offer a healthy range of bonuses and promotions. With a deposit match, the casino will match your cash with bonus funds. You can release the funds by playing a choice of slots or table games within the time period. Plus, you can join a VIP scheme and earn player points every time you play a game or slot for real money.
Some online sportsbooks and poker sites even have casino games and slots running alongside their usual offerings. Use your sports betting or poker bankroll to play your favorite slots, and vice versa.
Slots sites won’t feature any roulette, blackjack, or sports betting options. You will only be able to play online slots but the selection can often be bigger than you’ll find at casinos. You might also enjoy a bigger range of slots bonuses like free spins and tournaments.
How to select the Best Slots to play for you?
Now you found what is the best online slots site for you to play. It is time to pick the best online slots games for you to play.
Here are a few tips and tricks to find the most enjoyable slots to play.
Play High Return to Player Slots
The Return to Player (RTP) is the percentage of bets that are paid out. Most online slots will have an RTP ranging between 93 – 96%, which is essentially the house edge. For example, a slot machine that has a 96% RTP will return £96 for every £100 wagered.
The RTP is often found within the game’s paytable information, but review websites will often make note of RTP and variance levels to indicate how often and how high payouts are likely to be.
Find the best software providers
Every online slot casino has partnerships with software providers. The best casinos have deals with multiple developers, giving you the best choice of games possible. In addition, some casinos offer exclusive slots and progressives that you won’t find anywhere else online.
You can usually find a list of slot providers in the casino lobby. Some casinos even let you filter and sort games by provider so you can get to your favorite games fast.
When looking for good software providers, always check that they meet the criteria:
-
- Licenses from reliable gaming commissions
-
- Independently audited games
-
- Good game availability on both desktop and mobile
-
- Healthy range of slot themes
-
- High RTPs and choice of volatility
-
- Good mix of classic slots, 5-reel games, and progressives
The top slots casinos will differ in the software providers they offer. Always look for at least 2-3 of these slots providers when choosing a good casino. They offer the biggest selection of slots with a variety of themes, jackpots, and bonus features:
-
- Microgaming
-
- NetEnt
-
- Playtech
-
- Quickspin
-
- Scientific Games (SG Gaming)
-
- iSoftBet
-
- Play’n GO
Turn up the tension with Slot Tournaments
Online slot tournaments are a great way of turning your love of video slots into gifts or cold, hard cash. Best of all, you’ll get to compete with your fellow gamblers for a slice of the prizepool!
Most good online casinos will run slot tournaments during the year. Just hunt out the best tourneys in the promotions lobby, making sure you pay attention to the time and date they take place.
Slot tournaments generally work in one of two ways. You’ll either receive a number of free spins to use, or, you just play with your own bankroll. However, the aim is the same: to win as much as you can over 20-25 spins.
In reality, you’ll simply have to record the biggest percentage win over your allotted spins. It doesn’t matter whether your regular stakes are 1p or £10: you can still take a share of the prizepool if you win enough relative to your original stake.
After your allotted spins, you’ll record leaderboard points. You can track how well you’re doing compared to the other players. You’ll then be awarded prizes or cash depending on your finishing position.
