There are so many other slot machine game providers in the igaming industry, even the most ambitious players may never get to all the best slot games online, but in recent years we have seen a sharp rise in independent studios working with top slot sites.

The biggest casino software providers like Microgaming, Playtech and NetEnt are well known by players and have some of the best-loved games around. But the scope of game variety across the market is huge and these smaller, independent studios can offer awesome slots too.

How you choose which online game provider to use is always up to the individual, but often players are drawn to new game formats, certain styles of play and carefully considered themes and mechanics.

Because there is so much competition among other game providers, it’s worth checking out the smaller options in case you stumble across the game that’s just perfect for you.

Exclusive Slot Games From Operators

Some big casino operators use exclusive online slot games to entice players to their sites, which can be made by other software providers or in their own mini-game studios.

This can happen through an initial launch partnership, where a games provider and operator strike a deal to launch a title at one exclusive venue for publicity before it is released across other casino partners.

Otherwise a casino may request a bespoke game suited to their clientele’s particular needs, with themes, features, bonuses, RTP and volatility tailor-made for a specific audience.

888 Casino - Large operator with the most extended list of exclusive slot titles. Millionaire Genie Slot is the flagship 888 Casino jackpot slots hosted by blue genie. This is one of the most long-established online slots, with free spins and sticky wilds that could help players win a progressive jackpot which averages around £1.9 million.

Other exclusive slots at 888 include Jackpot Jockey, Big Lebowski, Pirates Millions, Irish Riches, Steampunk Nation, Treasure Fair, Snack Time and The Royals.

UnibetCasino: Meet the Meerkats is a 5-reel 40-payline slot from Push Gaming available to play on all devices and has two bonus features - free spins and hold and respin.

Hit2Split is another title exclusive to Unibet, and is powered by Net Entertainment. With a fruity theme, this 5-reel 30-payline slot has double symbols giving you the chance to get 10 symbol winning combinations as well as a free spins feature where you can get up to 30 free spins with a 3x multiplier.

PartyCasino - Mega Fortune Wheel is based on the smash hit game show Wheel of Fortune, a slot created by the developers at bwin to offer players the chance to spin for a chance of some juicy progressive prizes.

Mellon Madness has five different progressive jackpots on its simple fruity theme, with an RTP of 92.88% based on spending 100 coins within the game to give medium volatility with low and high payouts in bursts.

Leo Vegas - Leo Vegas Megaways is a popular exclusive title at Leo Vegas, that offers players nearly 120,000 winning ways with each spin of the reels and is ideal for casual gamers with wagers of between .20 coins and 10 coins per spin accepted.

Book of Destiny from Print Studios plays out on 5 reels with 10 paylines and has high volatility with wins up to x5,000 your stake.

Papaya Pop is inspired by the glitz and glamour of the Art Deco period of the 1920s and contains stunning visuals and a jazzy soundtrack.

The Benefits of Trying Slots from Smaller Game Providers

There are a number of benefits to playing slot games from software providers outside the most well known.

These smaller brands put a huge amount of effort into making their creations different to what is already out there, with unique graphic designs, functionality, original themes and new game formats and styles of play.

Because they are less focused on creating titles that appeal to the largest numbers of players, these studios are often able to make content that resonates deeply with smaller groups.

Despite their lesser resources they often challenge the big game studios for gamification, features, design and other bright ideas that players appreciate.

Trying a smaller game provider could see you stumble across a brilliant title that is not being widely used, offering better payout possibilities and fresh and quirky themes to games.

Security and Safety of Smaller Game Studios

The security and safety of players using smaller game studios is usually very similar to the biggest providers on the market.

In order to gain the trust of players and become successful, smaller providers invest in supporting all the primary responsible gaming measures coming from external regulators like eCOGRA and iTech Labs as well as government organisations such as the UK Gambling Commission and Malta Gaming Authority.

Our reviewers will research the company that owns the sites we review, checking how long they have been around for, reading reviews and looking for customer complaints or security breaches. We’ll search for any award wins and ensure all sites are licensed and regulated operators with the liquidity to cover any winnings you might make.

We also check payment options as all providers should offer a range of popular banking methods, such as Visa and PayPal, which all employ strict security protocols. And we make sure they pay out within the timeframes given.

We only list safe, secure and licensed UK slot games and online casinos and would never recommend unreliable, unsafe or untested game providers.

How we Rate and Review Other Game Providers on SlotSource

Our dedicated team of professional casino experts spend a lot of time and effort rating and reviewing each software provider in order to arm our readers with as much pertinent information as possible to allow them to pick the right game and site to play on.

They will sign up for an account at the casino in question where they can test the speed, ease and level of security involved in the registration process. They will claim bonus offers and play through the wagering requirements to see if they work properly and make deposits and withdrawals in order to assess how quick and effective the banking process is.

The reviewers will play games for free and with real money on a wide range of slot titles, allowing them to ensure the games we recommend are fair whilst assessing the overall user experience.

Other game providers will be judged on game variety, game quality, user experience and overall strength of their slots range. This takes into account a wide variety of payment methods, number of reputable software providers featured, quality and quantity of exclusive games, ease of navigation, functionality across various platforms, strength of design and usability and level of safety and security.

They will interact with the customer service teams to see how players are treated, analysing how quickly issues are dealt with and the general level of professionalism, helpfulness and knowledge displayed.

Once this is done we can confidently compare other game providers against one another and display the best available. We check all new casinos UK players can use and return to established sites to reassess them. If standards slip, we will not hesitate to reflect that in our honest and unbiased reviews.
