Online Slots UK

Welcome to Lottomart, the home of jackpot entertainment and one of the premier destinations for online slots in the UK! We host over 2,500+ games from top providers like Pragmatic Play, Red Tiger, Microgaming, Blueprint Gaming, Light & Wonder, and more. Enjoy classics like Big Bass Bonanza, Fishin' Frenzy, and Immortal Romance, among others.

We have something for everyone at Lottomart Games! Whether you enjoy Irish-themed, Vegas-style, or jackpot slots with fixed or growing prizes, Lottomart has you covered. We're always adding new titles, like Slingo games and Blueprint Gaming's Jackpot King slots, to keep the excitement fresh!

How To Play Online Slots

Online slot games work similarly to physical versions found in brick-and-mortar establishments. At the most simplistic level, online slots use an RNG (Random Number Generator) to ensure that every spin is fair. Players place a wager at the start of each round before any spinning occurs, with potential winning combinations getting revealed once the reels stop spinning.

The symbols in online slots vary but often include traditional playing cards or themed icons. Irish-themed slots, for example, can feature symbols comprising horseshoes, gold pots, and more. Look out for bonus symbols like Wilds and Scatters, which can trigger special features like Free Spins.

Slot games use different grid layouts and paylines, with various bonus features to keep things exciting. 5x3 and 5x4 are the most common layouts. However, Megaways slots usually (but not always) employ 6 reels, with anywhere between 2 - 7 rows, depending on the on-screen action and size of the symbols. Cluster pays slots might use an 8x8 formation instead.

Most online slot games also have their fair share of bonus features, from free spins to fortune wheels, multipliers, mini-games, pick-me, mystery prizes, and much more, making the slots fresh and exciting. The only real difference between traditional and online slots is the accessibility factor - the latter are more accessible, as you can play them at home or on the go thanks to the HTML5 framework developers integrate.

How To Win Online Slots

Winning involves landing symbol combinations across paylines; this can happen by spinning the reels or mechanics like cascading reels. Bonus symbols like Wilds and Scatters can help create wins or trigger features like Free Spins.

Some slots offer progressive jackpots, which can pay out potentially lucrative sums. Red Tiger slots, for example, have progressive ten-minute and daily jackpots attached to them that must drop by a certain time each day, and players can potentially win a substantial amount that way. Blueprint Gaming's Jackpot King network works similarly, with each spin contributing to a prize pool.

Best Online Slots UK

One of the best things about playing at Lottomart is the sheer variety of online slot games we host on-site. That includes some of the most popular and well-loved slot games ever created.

Pragmatic Play's seminal Big Bass Bonanza series showcases captivating online slots with vibrant themes and immersive gameplay. At the heart of this series lies 2020’s iconic Big Bass Bonanza slot; this seminal online slot game showcases a 5x3 grid with 10 paylines, while the fisherman symbol can collect fish symbols with cash prizes.

Big Bass’s main competitor is Blueprint’s Fishin' Frenzy series. So, take to the water in the classic 2014 original, and get ready to cast your reel and hook in potential wins of up to 50,000x the stake! 2019's Fishin' Frenzy Megaways mixes up the action with a randomised number of symbols on each reel, with a maximum of 7 active symbols on any spin.

The Eye of Horus slot transports players to the mystical world of ancient Egypt. Players appreciated the ancient Egyptian theme woven throughout the slot which led to Blueprint continuing to release well-received sequels like 2019's Megaways-infused sequel and 2021's Eye of Horus The Golden Tablet. Of course, a Jackpot King-enhanced version of the Egypt-set slot followed.

These are far from the only ones. Premier slot developers like NetEnt and Microgaming have created their array of thrilling online slot games. The former released the galaxy-spanning Starburst in 2012, and the brilliant fusion of Las Vegas bravado and classic fruit machines that is Twin Spin in 2013. Both received sequels. The latter’s best-known slot must be 2006's Mega Moolah, the jackpots of which can pay in the millions! Players can also enter the thrilling realm of gods and myths with the electrifying Thunderstruck slot series, including 2021’s Wild Lightning!

Variety of Slots

Slot developers are always experimenting to create the next best thing in slot gaming, thinking outside the box to create immersive and unique gameplay mechanics that they think will captivate players.


One such slot developer is Australia-based Big Time Gaming. They created the innovative Megaways mechanic for online slots; this alters the number of symbols on the grid during a spin, resulting in over 100,000 or more paying combinations. Usually (but not always) Megaways slots use a 6-reel setup with anywhere between 2 - 7 rows and a maximum of 117,649 paylines. Megaways slots can also have a horizontal row above or below the main game grid. Some developers have found a way to leverage the mechanic for an increased number of paylines. One example is Iron Dog Studios' 1 Million Megaways BC that leverages the engine to produce up to one million potential paylines!

Jackpot King

Developers like Microgaming and Red Tiger have integrated progressive jackpots in their online slots, making them popular and potentially lucrative. Blueprint took this idea and ran with it. Their idea was: why don't we take our best slots and make progressive jackpot versions of them? That's how Jackpot King slots were born. The progressive jackpot network has breathed new life into some of the studio's signature slots, and with good reason. Here is how it works. Jackpot King mechanics contribute to a shared progressive prize pool. Winning the Jackpot requires first that players land 5 Jackpot King symbols in the base game; this triggers a mini-game with bonus reels in which players match symbols for a chance to win one of three progressive jackpots: Royal, Regal and (most lucrative of all) Jackpot King. One of the most popular Jackpot King games is the Eye of Horus Megaways version (no surprise, given the double whammy of Megaways and Jackpot King mechanics).


Players looking for something truly unique will want to play our selection of Slingo slots. And what exactly is that you may ask? Slingo (AKA Slingo Bingo) is a thrilling fusion of bingo and slot games created over 30 years ago! Slingo slots operate on a 5x5 game grid. Each cell contains a random number. Below the grid is a reel with numbers. The idea is to spin the reel to get a number. If it matches any of the numbers in the corresponding column above, you can mark them off. The goal is to create horizontal, vertical, or diagonal lines of marked-off numbers as in a traditional bingo game. Some titles experimented with the formula, adding extra features like free spins, respins, Wilds and other symbols. One of the most popular Slingo games is Slingo Starburst, showcasing a bonus feature that occurs within the classic Starburst reels, complete with paylines, symbols, and more!

Nor are the above three the only types of slot games available. Other studios offer unique mechanics that have also proved popular with players. Red Tiger, for example, integrates its proprietary Power Reels mechanic that allows for an expanded game grid with more rows and columns than the standard setup. Others use the Link&Win feature, via which certain reels are held in place while others spin others to create potential winning combinations. We have also begun to release crash games which are a new variation of slots with the most popular being the Aviator casino game. Whatever your choice of gameplay mechanics, we're bound to have it here at Lottomart!
