A Guide To All Slot Sites

There are 1000s of online slot sites for gamblers to pick from today. The market is booming. With hundreds of new games arriving each month and new casinos cropping up all the time, we are spoilt for choice. So how do you decide where to play next? Well, each of us may have different priorities when choosing a site, though for most of us the free spins and bonus package for new players will be pretty high up on the list. If you are a seasoned player then you will probably have a favourite game, or even a game provider that you look out for too.

And of course, you should always make sure you gamble at a site that is fully regulated by the UK Gambling Commission, provides a safe and secure cashier, and offers a professional support service to help with any queries or complaints you may have. With all this in mind, the following guide should help you find the right slot site from our list.

Slots Bonuses

When you join any new casino you will be offered a welcome package, usually consisting of free spins and deposit bonuses. These offers are an incentive for you to join and also an opportunity to test drive the site, get a feel for the cashier and the game selection, and decide if you want to continue playing there. If you are a regular casino player then you will probably know that not all bonuses are the same. They come in all different shapes and sizes, with varying wagering requirements and withdrawal restrictions attached, and you should always check these out in the significant terms and conditions before signing up and depositing.

What to look out for when choosing a bonus:

    1. MINIMUM DEPOSIT

      Always see how much you need to deposit before you can claim the bonus. The minimum deposit is usually £10 but it can be as high as £25 in some offers on our site. Don’t get caught out or you’ll be calling customer support for your money back!
    2. MAXIMUM BONUS

      If you are planning on funding big with your first deposit then make sure you check to see the maximum bonus you will be eligible for. If the top limit is £100, you won’t get any more no matter how much you put down.
    3. WAGERING REQUIREMENTS

      Almost all bonuses come with wagering requirements. This is the amount you must wager before the bonus itself, and any winnings generated, become withdrawable cash. The multiplier is usually around 30x but can be much higher.
    4. WIN LIMITS

      There will also normally be a limit to how much you can win with your bonus funds. This applies to free spins as well. Anything from £100 up to £500 is a typical limit. If you go over, any excess will be forfeited when you go to withdraw.
    5. EXPIRY DATE

      Casino operators like to put an expiry date on their bonuses. If you don’t use the spins or bonus funds before the specified date then they will be forfeited. Don’t make that mistake – their free and there to be enjoyed.

Best No Deposit Slot Sites

Though no deposit bonuses are rare, it is still possible to pick them up when operators are feeling generous. Check the wagering requirements on any winnings as they are not likely to be immediately withdrawable.

Slots Games and Software Providers

It’s definitely worth checking out the game catalogue at any casino you are thinking of joining. There are hundreds of game providers creating slots each month and thousands upon thousands of games to choose from. The biggest and best-known software companies are names like NetEnt, Big Time Gaming and Microgaming. But there are lots more, from Scandanavian slots specialists like Yggdrasil, Thunderkick and Quickspin, to smaller, up and coming studios like Relax Gaming and Iron Dog. In our reviews you will be able to find listings of the providers for each slot site, and the names of some of the top games available to play.

It’s definitely worth checking out the game catalogue at any casino you are thinking of joining. There are hundreds of game providers creating slots each month and thousands upon thousands of games to choose from. The biggest and best-known software companies are names like NetEnt, Big Time Gaming and Microgaming. But there are lots more, from Scandanavian slots specialists like Yggdrasil, Thunderkick and Quickspin, to smaller, up and coming studios like Relax Gaming and Iron Dog. In our reviews you will be able to find listings of the providers for each slot site, and the names of some of the top games available to play.

Here are some points to consider when choosing a slot game.

      1. THEMES AND SOUNDS

        Every slot game has a theme of its own. Some are very popular – Ancient Egypt, Pirate Ships, Popular Movies – whilst others are more obscure –  Steampunk or Science Fiction. If you’re going to spend some time with a game, make sure it’s one that looks good!

      2. SLOT RTP

        The Return to Player will tell you how much money a game is likely to pay out in winnings as a percentage of all the money wagered. Pick a slot with a higher RTP to get a better payout rate.

      3. SLOT VARIANCE

        If you’re playing for the big wins then look out for the games with big prize potential, or progressive jackpot games like NetEnt’s Mega Fortune or Micorgaming’s Mega Moolah.

      4. SLOT JACKPOT AND PAYOUT POTENTIAL

        If you’re playing for the big wins then look out for the games with big prize potential, or progressive jackpot games like NetEnt’s Mega Fortune or Micorgaming’s Mega Moolah.

      5. SLOT STAKE RANGE

        Never gamble more than you afford. Slot games offer a range of stakes, usually from 10p up to £100. Always pick a stake level that you are comfortable with to give you some game time with your overall balance.

Slot Game Return to Player (RTP)

The Return to Player (RTP) is the average amount that will be paid out as a percentage of the overall money wagered on a game over time. Most slots have an RTP of around 96% to 97%, though some will be lower and some will be higher, even getting closer to 99%. It’s important to remember that this is an average number, not an absolute statistic! Just because a game has an RTP of 95% doesn’t mean that it will always pay out £95 on every £100 wagered. That would be very boring, and pointless! No, this is the average – some of us will experience much better returns on our wagering, and some of us will experience much lower returns. However, it is a useful number to know, and if you are looking for better odds then you could try playing games with a higher than average RTP.  Here are some of the best.

5 Slot Games High RTP

BLOODSUCKERS II BY NETENT (98%)

GOBLINS CAVE BY PLAYTECH ( 99.32%)

UGGA BUGGA BY PLAYTECH (99.07%)

MEGA JOKER BY NETENT (99%)

STARMANIA BY NEXTGEN (97.87%)

Slot Game Variance

The other significant slot feature to look at when choosing your game is the variance. This will tell you how volatile a game is, by which we mean, how far from the average return to player the payout may vary during your session. Low variance games will not drift far from the RTP so will pay out in small, regular amounts. These our considered to be low risk games. High variance games, considered to be high risk gambling, are those where the payouts will be well outside the normal RTP during your game play with long periods of dry spins with a very low RTP, followed up by short bursts of very high payouts. If you are new to slots, or if your budget is small, then high variance games are to be avoided because they can use up your funds very quickly with no return. If you are in for the high stakes, high drama of massive win sequences that come from games like Bonanza and Dead or Alive then high variance will be your thing and you should seek out these titles.

Slot Site Payment Options

After checking out the bonuses and the games on offer at your prospective casino you should also consider which payment options are available to you. You may choose to deposit with a debit card which all operators will facilitate. However, there are other options that you are available at most sites, and each one comes with its pros and cons. If you are interested in using an eWallet then Paypal is a good choice as it is accepted at many slot sites and offers fast and free deposits and withdrawals. Other eWallets, including Skrill and Neteller are also widely accepted and come with the same advantages, as well as allowing you to transact without directly sharing your bank details with the gambling operator, which for many is a more safe and secure method of payment. Elsewhere, mobile slots players may like the opportunity to deposit via their mobile phone using BOKU. This simple method has a daily limit of £30 and funds are added to your phone bill or removed from your current balance.

You can find out about each of these in our Slots Payment Guides.

Casino Licensing

You must make sure that any online casino you choose to play at is fully licensed by the UK Gambling Commission. Every casino listed on All Slot Sites has been issued with a license by this body which is responsible for regulating the industry in the UK and ensuring that operators act responsibly to ensure vulnerable gamblers are not exploited, that their platforms are not used for criminal enterprise, and that the service they provide is safe, fair and fully audited. You will also find that almost all the sites in the UK are licensed in an international jurisdiction, by a body like the Malta Gaming Authority or the Gibraltar Gambling Control Commission. Operators like to base themselves in these territories because as well as offering online gambling operator licenses, they also provide favourable taxation laws. You can check the licensing status of any online casino in information in the footer of the website.

Responsible Gambling

Gambling at a licensed casinos ensures that you are playing slots that have been audited to ensure the outcome of each spin is entirely random, and that in the event of a dispute over a game, or your account, you have recourse to a third party. But that is not all that is important. Licensed casinos are also required to provide vital Resonsible Gambling features in your account to help you manage how much you spend per day, per week and per month, and to give you the option to exclude completely by having your account locked and your address removed from all marketing lists. Problem Gambling is a high-profile issue in the UK right now. If you think that you may have a problem with the amount you are spending on gambling then you can find out more about where to get help on our Responsible Gambling page.
