Our first choice: Gala Casino
If you’re after a big collection of slot games that you can freely choose from, try Gala Casino. It has probably the biggest collection of online slots – the number of games is north of 300.
Feel free to pick any one of them and play. But if you want us to recommend you a game, then you can try Crown Gems Hi Roller, Ted, and Rainbow Riches.
The return to player (RTP) is an important factor in a slot game, and typically the bigger the RTP, the bigger your odds of winning. So, we recommend you to play Goblin’s cave because the RTP of this game is the highest on the site.
You can also get a free welcome bonus for your initial deposit – in the form of up to £400 of free money with which you can play.
Ladbrokes is known as one of the biggest online casinos in the entire United Kingdom. It has stood the test of time and it has become a fan favorite.
You can use many different payment methods at this site. Even PayPal is accepted as a valid deposit and withdrawal method for the slot games. There are quite a few other methods of payment as well – Skrill, Visa, MasterCard, Ukash, and many others. There’s a welcome bonus for new players and it consists of a 100% increase of your original deposit, up to a level of a £100.
The VIP club is set in place at this casino, and the members of it have an exclusive access to certain promotional offers and discounts that players can use in order to win big money. The tech support at this site is top notch, and it’s always a pleasure to be able to communicate with the tech team in different languages.
You can get the welcome bonus if you just enter the promo code “LOVELIVE”.
Betfred casino was a bookie when it originally started operating. Nowadays it has a hefty slot game collection that’s on par with that of most online casinos. There’s a huge welcome bonus of up to £200 and you can use this free credit to play Goblin’s cave, Vacation Station, or Beach Life for an example.
If you deposit £5 pounds, then you will get £25 worth of free money that you can use to play on the slots.
And there’s a special offer for those among you that won’t be lucky. For every £10 that you will lose in some games, you will get a free spin which you can use to try and get your money back. This offer is valid only for the following games: Jungle Jim, El Dorado, Tarzan and Lost Vegas.
If there’s a bad thing about Betfred casino, then it’s the fact that there are no VIP offers set in place for the casino players.

Welcome to the World of Online Slots
Most gamblers have heard and experienced the phenomenon of the online slots. But for the few among you that haven’t done this – the online slots are games much like the original real life slot machines. You can play these slot machine games online, and all you’ll need to do so is an internet access device, such as a laptop or a cellphone, or even a tablet. The games themselves are sold by vendors to the various gambling companies that operate online, and the two chief forms of online slot machines are the slots that you can download, and the slots that you can play directly, without needing to download anything.
In the beginning, the online slot games had only three reels with a single pay line – this was the classical design. But as time went by the software creators began adding up new innovations, and now you can find online slot games with several reels, as well as multiple pay lines. There are certain cases where you can play with ten reels and dozens of different pay lines.
Some software developers have introduced an innovation that replaces the so called pay lines with an alternative. With this new design you now have many different ways in which you can win after a single spin. It’s not all that complicated – this alternative to the pay line uses the same principle of work as the classic pay line. If you play a game of this type, then you will see some odd looking symbols during your playing experience.
These symbols typically are the wild symbols, and the so called scatter symbols. The first ones are a substitute for other symbols. The wild symbol can take the place of any other symbol that you may need on a particular pay line in order to make it a winning pay line. And the scatter symbols are typically a road to a bonus game where you will most of the time get free spins. These symbols are very popular among players and they increase the odds of winning money.
The principle on which the online slot machines work is based on the work of a random number generator. This is a computer algorithm that randomizes the results and it connects the numbers to an algorithm.
If you’re new to this, we must tell you that playing the online version of the slots is pretty simple. All you will need to do is to make a first deposit, and then select your favorite slot game. Choose the number of pay lines that you wish to play on, and place your bet. After that, you can click on the spin button and hope for the best.
There are many different online casinos that offer slot games, in the UK. Our list featured some of the top companies that operate in the UK. Our final advice to you would be to go and check out the terms and conditions of a particular website where you’d like to play, before depositing any money, just to be sure on what the rules and conditions are.
