Game Selection at Prime Slots – 4,000+ Online Slots for UK Players
Prime Slots lives up to its name – it’s all about slots, and the catalogue is stacked.
Here’s what you’ll find:
Classic Slots
Traditional 3-reelers with simple mechanics and fast spins.
Video Slots
Packed with features, animations, and bonus rounds. Big names like Gonzo’s Quest, Book of Dead, and Reactoonz are all here.
Jackpot Slots
Progressive jackpots and fixed pots with huge potential – Mega Moolah, Divine Fortune, Eye of Horus Jackpot King, and more.
Megaways™ Slots
Randomised ways to win with every spin – Big Bass Bonanza Megaways, Monopoly Megaways, etc.
Slingo
Slingo is a fast-paced, hybrid casino game that cleverly combines elements of online slots and bingo into one exciting format. Originally developed in the 1990s and now featured on many UK casino sites, including Prime Slots, Slingo has become a favourite for players who enjoy quick wins, bonus features, and number-matching action.
The game takes place on a 5×5 bingo-style grid filled with randomly generated numbers. Below the grid is a slot reel that spins and reveals five numbers at a time. If a number on the reel matches one on the grid, it’s marked off — just like in bingo. The goal is to complete horizontal, vertical, or diagonal lines, known as “Slingos.”
As you create more Slingos, you climb the prize ladder, unlocking better payouts and sometimes special bonus rounds. Many Slingo titles also include wilds, super wilds, and multipliers to boost your chances, plus familiar slot-style elements like free spins or themed mini-games.
Scratch Cards & Instant Win
Quick-hit games with low-stakes excitement and easy rules. At Slotsquad, we’re big fans of fast-paced casino games, and nothing delivers that quick-hit thrill quite like online scratch cards. These digital versions of the classic scratch-off tickets give you the same rush of revealing hidden symbols — only faster, flashier, and often with even bigger prizes.
Online scratch cards are designed to be simple, fun, and ultra-rewarding. Each game presents a digital panel with covered sections — usually 3×3 or 5×5 grids. You use your mouse or finger (on mobile) to “scratch” away the coating and reveal the symbols underneath. If you uncover matching symbols or numbers in the right combination, you win.
Unlike slots or bingo, there’s no spinning, no reels, no waiting — just instant outcomes. Most scratch card games also feature automated scratch options, so you can go as fast or slow as you like.
Prime Slots works with over 50 providers, including NetEnt, Play’n GO, Pragmatic Play, Red Tiger, and Big Time Gaming – ensuring a diverse experience for every kind of player.
Software Behind Prime Slots – SkillOnNet Platform
