How to Find New Slot Sites?

Finding the latest online slots is easy, all you have to do is simply google. However, there is an art and science to finding the best video slot sites. The first thing that you need to do is separate the scams from the genuine.

The web is crawling with sites that will promise you great wins in return for your money. Check the credentials of those scam sites by reading their reviews. Gambling is strategy and chance, and if any site is promising you loads of money, you must avoid it.

The second thing you should look out for is ‘https’.

If you are gambling for money, look out for sites that have ‘https’ before their URLs. For example, https:// This means you can pay and withdraw money safely and securely on this platform. Your payment information won’t be exposed to fraudsters.

Having identified the first two steps towards finding a new site, let’s move ahead. All good slot sites are licensed by gambling regulators. Check whether your gambling site has received a licence from the U.K Gambling Commission or other regulatory authorities.

Licensed slot sites are trustworthy and fair and their games are regularly checked by the authorities.

Top Slots Sites in the UK

Which Slot Sites Are the Best?

Let us discuss the main attributes of a great online slot. First, that site should have a wide variety of games.

These game providers have been in the business for quite some time and are known for their high standards, commitment to quality, and excellent game design. Online slots should also have a range of payment options.

Some players prefer paying through their Visa or Mastercard credit cards. Other use net banking or private wallets. Lately, many players have begun making payments through their mobile phones.

An online slot that offers a range of payment options is seen as helpful by the players. Slot sites should be accessible on mobile phones, desktops, and tablets. Some of the best online casinos run on the JS and HTML5 technologies and are mobile-friendly.

Does your online slot have a good customer care department? How quickly does the customer agent solve your problems? Does your site have an FAQ section that has answers to all the common problems?

The Best Sites for Winning

All the best slot sites have great bonuses and transparent rules. Let us have a look at some of the bonuses available in the online gambling world.

When you open your account in a new casino site, you are often required to make your first deposit. Once you pay that amount, you are awarded a matching bonus. For example, upon depositing 100GBP, your site might award you virtual money worth the same amount. Some sites might even award you some free spins too.

Note that this virtual money is for gambling purposes only and cannot be withdrawn. Read the T&C’s of your matching casino bonus.

Several UK online casinos continue with their matching bonus offer as you continue in your game. So, when you make your next deposit, you are given another matching bonus. Matching bonuses are often capped by slot sites.

Please note that these bonuses are applicable to just a few games (in this case slots). If you have received a few free spins, check the T&Cs. Some sites give you Reload Bonuses as well for your loyalty.

If you are a high roller, your site might give you special privileges. Some online slot sites reward loyal players with VIP privileges, relationship managers, etc.

No Deposit Slot Sites

Not all slot sites require you to make initial deposits. There are several sites that let you play for real money without making any deposits.

All you must do is create your account and begin playing. However, your bonuses may not be as attractive as those related to deposit sites. Your no deposit bonus might also be subjected to a detailed list of Terms and Conditions.

Read that list before claiming your first No Deposit Bonus. If you are a new player, you may try out the No Deposit Slot Sites. This way you don’t commit any funds, but stand to gain a significant amount of money.

Your slot site might award you no deposit bonuses in different forms. Some sites give away Free Spins to be used on select slots. You might also receive cashback from your site after playing select games.

Cashback bonuses normally comes in the range of 5-10%. No Deposit Bonuses don’t come to you automatically; you’ll have to claim them by entering your Bonus Codes before playing your slots.

Almost all no deposit slot sites have wagering requirements. This means you will have to wager a minimum amount of money in order to use your bonus. Also, be mindful of the Cashout limits imposed by the sites.

New Slots in the UK

Every year, the UK is flooded with the latest slots, each offering competitive Return to Player percentages and payouts. Game of Gladiators from Play n’ Go has 5 reels and 20 paylines and features Roman gladiators. With luck on your side, you can win large amounts in the jackpot rounds.

If you are cautious player, you can begin with just 20 pence per spin. The maximum that you can bet is 100 GBP. There are 6 Bonus Rounds in this game. Game of Gladiators also features a Wild symbol. Another exciting new slot in the UK market is Narcos.

Narcos from NetEnt is based on the gripping story of Pablo Escobar, one of the most infamous drug lords. Adapted from the Netflix series of the same name, Narcos has 5 reels and 243 pay lines.

5 Facts About Online Slot Sites

The slots that you play are run by Random Number Generators. Also called as RNGs, these are complex computer programs that generate random numbers. Put simply, this means that there a very low chance of someone influencing your game outcomes.

Slot machines have been popular since 1881 when the first such machine was invented by Sittman and Pitt. Online slots come in two different variations; classic slots and video slots. The former sport bells, candies, whistles, bars, etc. Classic online slots don’t have unique storylines that the video slots do.

Classic online slots are straightforward to play. If you are just starting out, try these online slots.

There is a third type of online slots and these are progressive jackpot slots. Several well-established slot sites have progressive slots that give out handsome amounts of money to the winners.

These slots are so-called because their sizes increase incrementally every time a new player joins in. Progressive Slots are of 3 types- Standalone, Wide-Area, and Linked.

The jackpots of each of these slots vary in size. Finally, the maximum money that anybody has won on a progressive slot is John Heywood of Cheshire, England. He won 13 million GBP on Mega Moolah after betting just 25 pence!

Slot Sites and Customer Service

One of the biggest reasons why gamblers prefer a particular slot site is the latter’s customer service. People are playing for money, they gamble big or small amounts of money, and often they land up in problems.

Click on it and it will expand. You can then interact with the customer agent by posting questions.

In many cases, your customer service agent will reach back to you after a few minutes. Don’t get frustrated, there is a long line of other customers waiting for their turns too!. Some slot sites have a contact email on their home page.

Just shoot your queries to this email and receive your answers quickly. However, the vast majority of online slot sites have a detailed Frequently Answered Questions section.

This area contains answers to some of the most commonly asked questions. Head over to this FAQ section, enter a few keywords in the Search Box, and see your question pop up with its answer.

Online Slot Sites, Payment Methods and Security

We belabour this point on security here again because a vast majority of new gamblers worry about payment security. Online sites are all the time investing heavy amounts of money on cybersecurity. This is important because each day, millions of GBP are being transacted on these sites, daily.

A large percentage of these bets are made by novices who are worried about their payment details. However, you need not worry about your details being stolen by hackers. Every time you enter your credit or debit card details, that information becomes automatically encrypted.

Also, all the information that travels from one point to another passes under a virtual tunnel.

While credit and debit cards remain hugely popular among online gamblers, you might also try virtual wallets such as Skrill Paysafecard and PayPal. Opening a virtual wallet account is easy, and just takes a few steps. Some slot sites prefer normal banking methods where your funds are debited/ credited to your bank account directly.

You can even make payments using bitcoins and other cryptocurrencies. However, before transacting in BTC, ensure that your online slot site supports this payment option. The sunny side is that the many UK based online slot sites have exclusive bonuses for BTC customers.

Of late, many slot sites have begun accepting payments through Google Pay also.

How to Win Big Without Betting Big?

It isn’t easy to win big amounts of money on an online slot. However, with the right strategy, and a little bit of luck by your side, you can win a small fortune.

Most slot operators don’t disclose the odds of winning a slot. However, some UK online casinos do share this information. Once you have this data, it is time to begin. Identify those slots that have the highest RTPs. Another way to look at things is by finding sites that pay out big amounts of money.

Now here comes the catch; it is not necessary that a slot’s payout remains constant across all the casinos.

For example, a slot X which has an RTP of 99% may have differing payouts in casinos A, B, and C. You can also begin by finding those games where you can bet small but earn big. A smart way of improving your chances is to find games with small jackpots.

Many players make the mistake of going in for the big jackpots and spending long hours chasing that big win. Look at the paylines in your slot; if it has 25 paylines and you are betting just on 5, then you are losing out on the other 20. Try to bet on all the paylines within your budget.
