How Do Online Slots Work?

Online slot games work similarly to traditional video slots. First, they use an RNG (Random Number Generator) to ensure that every spin is fair. Second, players place a wager at the start of each round before any spinning occurs. Third, potential winning combinations get revealed once the reels stop spinning.

In terms of reel sets, the number is usually from 3 (found in most classic fruit machines) to 6 (commonly found in Megaways slots). A pre-disclaimed group of winning combinations is called a payline; 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 the accessibility factor - the latter are more accessible.

And what are some of the most popular slot games? We've already mentioned some of the most popular games on-site, such as Rainbow Riches, Mega Moolah, Starburst, and Fishin' Frenzy Megaways. Want more fishing goodness? The Big Bass Bonanza series is a brilliant alternative. We also have classics like Wish Upon a Jackpot available at Lottomart Games!

Online Slot Game Providers at Lottomart

Here at Lottmart Games, we work with the best online slot game providers to bring you the best slots in the UK. We have slots from the teams at Red Tiger, Microgaming, NetEnt, Blueprint and more. More recently, we've parted with such studios as SG Digital (now known as Light & Wonder) and Play 'n GO 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 slot machines and table games. The current roster (standing at 4000 online slots), has been created using cutting-edge technology. 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. 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 a brilliant array of online slot games from the acclaimed developer, so definitely have a look at our website to see what we have!

Red Tiger

Developer Red Tiger has been around since 2014 and has consistently produced countless top-quality slot games. If you want a look at the sheer quality of the games, 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. So far, the studio has developed over 1000 slots, including Cash Splash slot, the first-ever progressive jackpot title. Today, they are perhaps best known for their Mega Moolah series of games, which could pay out in the millions! Microgaming is also responsible for the equally impressive Immortal Romance and Thunderstruck 2 slots, both of which are available to play at Lottomart right now!


NetEnt is one of the oldest casino game developers, having started in 1996! The studio began working on traditional casino slots, then switched to online slots at the start of the 2000s. NetEnt has gone on to develop more than 200 slots. Probably the studio's best-known title 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 Twin Spin slot series, which gives players a mix between Las Vegas and a classic fruit machine!

Blueprint Gaming

This stellar developer opened its doors in 2001, designing and creating 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). Into fishing? Then we can't recommend the Fishin' Frenzy series highly enough, which of course like many Blueprint slots has a Megaways entry, Fishin Frenzy Megaways! All these slot games and more are available to play at Lottomart!

Play Slots On Your Mobile Device

The days of having to be stuck at your desktop to play the best available slots are long gone, which is why the team here at Lottomart Games have made sure our wide range of online slots play just as well on all mobile devices and tablets as they do on a bigger screen. Lottomart has a fully optimised mobile casino for players to enjoy their favourite online slot games whilst on the go.

There's even a handy breakdown on each game to tell you if it's best enjoyed in portrait or landscape format so that you'll get the most out of your web-based and mobile slots experience.

Understanding What Makes The Best UK Slots

Now, some of you will be up to speed with all the online slot game lingo, but if you're just getting started, we have a few handy hints on what to look for.

Click on any of our great games to quickly see a brief breakdown of what to expect when you get going. Looking for collectables to keep the excitement building or random wilds that boost your win? Well, look no further than the game features to find the right online slot game for you! There are even handy breakdowns 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.

Regular New Online Slots

Are slots games random?

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.

How do online slots pay out?

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.

What are some of the most popular slot games online?

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 series of slots centred around, what else, the art of fishing. Want more fishing goodness? Then, the Big Bass Bonanza series is a brilliant alternative. Plus it too has its own Megways edition. We also have classics like Immortal Romance or Dynamite Riches, with its theme of gold-prospecting. Whatever, you want, we’re sure to have it at Lottomart Games!
