Online Slot Game Providers at Lottomart

Here at Lottmart Games, we work with the best online slot game providers in the industry to bring you the best online slots in the UK. We have slots from the teams at Red Tiger, Microgaming, NetEnt, Blueprint and more. More recently we’ve parted with SG Digital (now known as Light & Wonder) to bring you the mega smash-hit series featuring Lucky Leprechaun and more! Let’s take a look at a few below.

SG Digital

SG Digital, or Light & Wonder, has been around since at least the early 1970s, providing both slot machines and table games. The current roster stands at around 4000 online slots, created using cutting-edge technology. Far and away their most popular series to date is Rainbow Riches, and here at Lottomart, we have a slew of iterations for players to discover, including an edition featuring the always popular Megaways mechanic. Moving away from the cheeky leprechaun, we have a whole host of branded games based on Monopoly, including Monopoly Mega Movers, so if you love the original board game, then you should check out these titles as well! From there, we have an amazing array of online slot games from the acclaimed developer, so definitely have a look on our website to see what’s available!

Red Tiger

Developer Red Tiger has been around since 2014 and has produced countless top-quality slot games during that time. If you want a look at the sheer quality of the games that they’ve produced in their relatively short lifespan, then look no further than these two slots, Dynamite Riches Megaways and Gonzo's Quest Megaways. Not only do these incorporate the popular Megaways mechanic, allowing for a mind-blowing number of ways to win, but the games are packed with features and bonuses in their own right!


This stalwart South African developer has been around since 1994, and since then has become one of the most popular names in the online slots industry. They are responsible for making over 1000 slots, among them the Cash Splash slot which was the first ever proggressive jackpot title. Nowadays, they are perhaps best known for their Mega Moolah series of games, which could pay out in the millions! Apart from this, Microgaming is responsible for the equally impressive Immortal Romance and Thunderstruck 2 slots, both of which are available to play at Lottomart right now!


NetEnt has the distinction of being one of the oldest casino game developers, having opened its doors in 1996! Having started out working on traditional casino slots, the developer switched to online slots at the start of the 2000s. Since then, NetEnt has gone on to develop more than 200 slots. Among the studio’s best-known titles is the jewels-in-outer-space-themed slot, Starburst, and it has remained a firm fixture with players ever since. It’s one of the most played games right here at Lottomart! Other luminaries by the developer include the Hotline series of slots, and if you're into a certain 80s TV show, then you should most definitely check them out!

Blueprint Gaming

This stellar developer opened its doors back in 2001. Since then, the studio has gone on to design and create an exciting range of UK slot games for both the online and mobile markets. As well as original content, Blueprint is also well-known for developing successful slots based on a broad range of third-party brands. If you want to play a range of high-quality slots that utilise the Megaways mechanic, then look no further than Eye of Horus Megaways, which also has the added benefit of being set in Ancient Egypt (for those who like that setting, of course). If you’re into fishing then we can’t recommend the Fishin’ Frenzy series highly enough. Of course, like a lot of Blueprint slots, this one has a Megaways entry, providing additional ways to win! All of these slot games and more are available to play at Lottomart!

There are even handy break-downs of the RTP % (Return to Player) and average hit rate so you can find out just how often those wins should fall, as well as the minimum and maximum bet amounts, top available prizes and how many paylines (how the symbols connect to create winning combinations) there are.

Online slot games can also come with unique game mechanics which makes the gameplay vary. For example, here at Lottomart we are very happy to offer an extensive range of Megaways slots as well as Drop and Wins games for our players to enjoy. We recommend looking into the different online slot mechanics before playing so you know what to expect when you begin playing.

UK Online Slot FAQs

Q: Are online slots random?

A: Yes, online slot games use a Random Number Generator (or RNG for short). When a player clicks to spin the reels, the most recent random number generated is the one that determines the outcome.

Q: How do online slots work?

A: Online slot games work similarly to traditional video slots:

  • They both use an RNG (Random Number Generator) to ensure that every spin is fair.
  • Players need to set a wager at the start of each round; once this happens the reels can then be spun.
  • The reels eventually stop spinning, potentially revealing winning combinations.
  • The number of reels varies usually from 3 (found in most classic fruit machines) to 6.
  • A pre-disclaimed group of winning combinations is called a payline, and each slot has a certain number of paylines. The more paylines a slot game has, the higher the chances of landing a winning combination.

The only real difference between traditional and online slots is that the latter is more accessible since they can be found online.

Can real money be won playing online slot games?

Yes, it can. The amount depends on the type of slot, the total bet staked, the number of paylines, bonuses, spins, respins, reels etc.

Q: What are some of the most popular online slots?

A: We’ve already mentioned some of the most popular games we have on-site, such as Rainbow Riches, Mega Moolah, Starburst and as well as the Fishin’ Frenzy Megaways slot game centred around, what else, the art of fishing. Want more fishing goodness? Then, the Big Bass Bonanza series is a brilliant alternative. We also have classics like Wish Upon a Jackpot available at Lottomart Games!
