    Paddy Power Games Welcome Bonus – Enjoy 150 Free Spins

    Anybody who has ever played Paddy Power will tell you the same thing! They are amazing when it comes to bonuses and promotions. And it starts the moment you walk through the virtual door, with a jaw-dropping 150 Free Spins when you sign up. There are two great reasons why this is a fantastic welcome offer. The first is that you don’t even have to deposit to enjoy the first 50 free spins. There’s absolutely no risk involved to your wallet whatsoever. Afterwards, you can enjoy another 100 free spins when you deposit £10. To redeem this part of the offer, you will need to opt-in with the bonus code PGCTV1. Secondly, and perhaps more importantly, there are no wagering requirements on your free spins! What you win, you win. You will need to wager through your £10 deposit on a Daily Jackpot game first, however. Spins can be played on Daily Jackpot Games at a value of £0.10 per spin. As with any opening offer, there are a couple of terms and conditions you will need to abide by, which we’ve summarised below.

    Terms and Conditions

    • New Players Only
    • Opt-In required
    • Free Spins value £0.10
    • Must be played on Daily Jackpot Games
    • Bet £10 on any Daily Jackpot Game

Play responsibly.

    Mr Vegas Casino Welcome Bonus

    The welcome bonus at Mr Vegas Casino comes in two eye-catching portions. First, new depositors can claim a 100% bonus, up to £200, just for transferring an initial bankroll amount. But, even better, if this transaction is completed within 24 hours of sign-up, newbies can also take advantage of 11 no-wagering free spins on the Pink Elephants 2 slot game. It is to be expected that welcome deals come with terms and conditions, and in the case of Mr Vegas Casino, these rules see players asked to wager their bonus 35x before winnings can be withdrawn. A standard requirement among most leading operators. Zero wagering on any promotion is the gold standard. So, the no-wagering demand related to the associated free spins on Pink Elephants 2 is an intriguing prospect.

    Terms and Conditions

    The welcome deal at Mr Vegas Casino is more customer-friendly than alternatives you will find at several rival operating firms. But you should still dig into the finer detail to ensure you receive the full benefit of opting into this scheme. Terms and conditions include:
    • Open to new players, 18+
    • A minimum deposit of £10 is required to qualify for the 100% and free spins
    • 11 welcome spins are available on Pink Elephants 2 when a player’s first deposit is made within 24 hours of sign-up
    • Bonus winnings must be wagered 35x before a withdrawal can be made
    +
  • Deposit £10+, Get 100% Bonus Up to £50 + 50 Free Spins on Book of Dead

    • VIP rewards for repeat depositors
    #ad. 18+. Gamble Responsibly. Begambleaware.org. 18+ New players only. 100% bonus up to £50 on first deposit + 50 bonus spins.

Max bonus cash-out £250. 40x wagering requirements. Bonus expiry 30 days. Bonus spins expiry 2 days. Game restrictions apply. Further terms apply.

    Casushi Casino Welcome Bonus

    Nothing is more enticing than a new player welcome bonus that comes in perfectly formed slices. Casushi Casino knows how to present a perfect promo platter with first-time depositors in line to pick up a 100% casino bonus, up to £50, and 50 free spins on the ever-popular Rich Wilde and the Book of Dead slot game. To qualify for this deal, new players must simply deposit £20. Several terms and conditions apply that should be considered. Among these, Casushi specifies that deposits that are made through Skrill or Neteller will not qualify for this offer. A factor that may influence the banking options chosen by some new platform customers.

    Terms and Conditions

    The big draw of this welcome bonus from Casushi Casino is that newbies can walk away with up to £250 should their bonus pay dividends. Most casinos restrict the amount players can withdraw from promo deals, and £250 compares favourably with competing outlets. However, this is not the only rule you must consider before trying your luck. Other considerations include the following:
    • This deal is only available to new players, 18+
    • A minimum deposit of £20 is required to qualify
    • 50 free spins on Rich Wilde and the Book of Dead slot are released in three parts. 30 free spins are playable on day 1, 10 free spins are playable on day 2, and 10 free spins are playable on day 3
    • The maximum bonus that players can receive from free spins is £50
    • The maximum bonus that can be cashed out as a result of bonus credit is £250

    Deposit £10, Play £10, Get £50 of Free Bingo Tickets

    Given the name recognition that Monopoly products command, many bingo players are likely to be curious enough to try out Monopoly Bingo without an incentive, so it is a pleasant surprise that such an enticing new player bonus is currently available. If you deposit £10 or more and wager this sum on bingo tickets or slot games, you qualify for £50 in free bingo tickets. This value is based on using 50 freebies to purchase entry to £1 per ticket games, with purchase restrictions and a cap of £750 applied to winnings.

    Terms and Conditions

    • Bonus bingo tickets range from 1p to £1 in value
    • Alternately, players can accept the 30 free spins slot bonus with spins valued at 20p each
    • All bonuses are subject to a 30-day expiry following an initial deposit being made.

    Tombola Bingo Welcome Bonus – Deposit £10, Play with £30

    Tombola’s opening gambit to attract new bingo players is superbly simple and comes with NO wagering requirements. To redeem this offer, simply opt-in as part of the registration bonus and deposit £10. And that is it! Obviously, you can’t then just withdraw the bonus fund, but you can withdraw any winnings from playing with the bonus cash. In other words – there are no wagering requirements. Yipee! No wagering requirement offers are pretty rare finds. They’re normally one in a long list of terms and conditions that you need to stick to. That’s not the case here. It couldn’t be any simpler.

    Terms and Conditions

    Virgin Games Bingo Welcome Bonus – Play £10, get 30 free spins or £50 of free bingo

    This is a nice, clean, and simple opening offer by Virgin Games. Simply deposit and play through £10 and choose either 30 free spins on the Double Bubble slot or £50 worth of free bingo tickets. Splitting your offer between slots and bingo is a great way to attract new customers, but an obvious value differential is at play here. Thirty free spins on 1p line slots or 50 smackers on bingo, and I know which I’d choose. As is nearly always the case, this opening offer comes with terms and conditions you must abide by. However, the massive plus for this opening offer is that it doesn’t have any wagering requirements. One word of warning, the max bonus here is £50 if you choose £1 tickets, but if you choose a minimum value room of just 1p then the bonus is only worth 50p. You must also select free bingo or free spins before you deposit and then wager through your first deposit of £10.

    Terms and Conditions

    • 30-day expiry
    • Slots must be played on Double Bubble
    • 1p coin size, maximum lines on Double Bubble
    • Bingo tickets are for applicable games only

What Are Independent Slot Sites?

An independent slot site is one that is built on its own exclusive platform. Many of the slot sites on the market are sister sites, meaning the same third-party operator runs them. Why is this so? Third-party platforms offering white-label solutions provide a cheaper and quicker option for new slot sites looking to launch. Some leading ones are Jumpman Gaming, Skill on Net, Aspire Gaming, White Hat Gaming, etc.

Building a new site from the ground up is a lot of work, but these companies offer already-made templates, strong marketing power, and greater liquidity for these new sites. A new operator simply pays for the package and develops its site on the platform. The result is dozens of similar-looking sites with the same layout, the same bonuses, payment methods, etc.

An independent slot site is not part of any such larger network. Instead, they stand alone and have no sister sites. These kinds of gaming sites are not very common, though. Those that exist are usually the result of a gaming company attempting to create a platform that manifests their vision, rather than simply putting out a new slot site for the sake of it.

Why You Should Choose an Independent Slot Site

A standalone slot site has definitely put in more work to establish something different. Here are some notable features of independent slot sites:

Unique Software

Independent slot sites have a unique range of software. As they’re not using any template software from white-label online slot platforms, they decide which games will be offered on the site. The library will often include their own proprietary games. But if you’re looking for popular titles from leading game developers like NetEnt, Pragmatic Play, Microgaming, Playtech, Big Time Gaming, etc., you’ll also find them here.

They are often selective with their picks and only partner with providers whose offerings align with their vision, so you may not find such a massive collection of slots. Since the numbers aren’t on their side, these sites aim for quality instead. They’ll often have a small but mighty range of games available for online or via mobile play.

Bonuses like No Other

Independent slot sites don’t use anyone’s template, so they offer bespoke welcome bonuses and other promotions. These standalone operators can take liberties with the bonuses they provide, and they sometimes add no deposit or no wagering features.

They offer exciting periodic bonuses, too, and can easily modify or improve their offer to meet players’ demands. This would be difficult for networked brands because a change in the bonus offer would mean overhauling all associated sites. Third-party operators are the ones who curate promotional schemes, so a complaint about the bonus would need to be redirected to the third-party operator.

More Generous Terms

The T&Cs available at a slot site is the greatest indicator of the value you can hope to gain from your gameplay. Many third-party companies impose some very strict bonus terms that apply to all their partner sites, whereas independent slot sites tend to have more relaxed rules. This shows that they care about players and are not just focused on their own profits. When there are favourable terms, you get a more rewarding bonus experience.

Varied Payment Methods

There are not necessarily many payment methods at these sites, but independent slot sites are your best bet at finding a unique banking solution.

Still, you’ll find popular payment methods such as Visa, MasterCard, Paysafecard, and prepaid vouchers. Where new independent sites may only have a few options, established operators will be able to cover all the popular methods available.

Design & Layout

Probably the most underwhelming part of many new online casinos is that they almost all look the same. As several sites run on the same platform, they bring the same cookie-cutter designs with just a few changes to the colour scheme and logo. If you’ve played at one, you’ve played at all.

On the other hand, independent slot sites are often built from the ground up. So they’ve got different designs and layouts. A lot of them use special themes that make the site more memorable. For instance, LeoVegas has an animal theme with a lion-inspired logo. Party Casino is another well-known independent site based on a colourful party theme.

Are Independent Slot Sites safe? – Licensing & Security

The importance of licensing is undisputed, whether at independent slot sites or white-label sites. Third party companies running multiple sites usually have one or more licences which cover the different brands under their umbrella. This is among the reasons why many new casinos and slot sites choose to launch under an already-established operator.

On the other hand, a standalone site will have to acquire a fresh licence. Getting a reputable licence isn’t a walk in the park and this may lead an independent operator to go for cheaper and easier licences like a Curacao Gaming Control Board licence. The problem with such certificates is that they don’t have strict requirements that guarantee fair play and security for players. As such they are not very reliable.

We personally check for sites affiliated with top licensors like the Malta Gaming Authority, the Kahnawake Gaming Commission, the Gibraltar Gambling Commission, and the Alcohol and Gaming Commission of Ontario (AGCO). The UK Gambling Commission (UKGC) is responsible for regulating all slot sites in the UK. The best sites on our list are UK-licensed, so you can rest assured of a safe and secure gaming experience.

Independent Slot Sites vs White Label Sites

Sites that are part of larger third-party platforms take a shorter time to launch. They also offer greater liquidity. So while an independent site may lack the financial capacity to redeem huge wins, large third-party companies can guarantee jackpot-sized payouts.

Standalone sites also don’t have access to the tools and features provided by large network operators. One such tool is ‘self-exclusion’ which allows players to curb problem gambling by excluding players from all related sister sites. You should be able to use GamStop at the best standalone sites, though.

Summary – One of a Kind Experiences at Independent Slot Sites

Any cluster of sites that run on the same platform will have similar bonuses. Sometimes, they are even perfectly identical. You also get the same range of games, and there are no distinct experiences. Where the owners have put in little effort to be original, there’ll be hardly anything memorable.

The greatest benefit of independent slot sites and casinos is that they stand out with bespoke offerings. You may find similar games here as well, but standalone casinos can offer diverse titles, including their own in-house developed games. You can also enjoy bonuses you’ve never seen before on a website that’s got its own identity.

Independent Slot Sites FAQ

What is the best independent slot site?

The best standalone slot site depends on the games you like and the bonuses you prefer. That said, all our recommended standalone operators will offer a memorable experience.

Are independent slot sites better than white-label sites?

There are advantages and disadvantages to playing at an independent slot site, so this depends on your preference. If a unique gaming experience matters most to you, then independent slot sites are the clear winner.

Are independent slot sites safe to play in the UK?

Yes, these sites are safe to play in the UK as long as the UKGC licences them. That is the case with most of the standalone operators we recommend.

Which bonuses can I get at independent slot sites?

Plenty of bonuses are available to claim at these sites. From welcome packages, deposit matches, and free spins to reload offers and cashback, these sites offer some of the most brilliant promos.
