Our online casino has earned a reputation as one of the UK’s most trusted online casinos, offering great games, fair play, a wide selection of payment options, and exciting casino promotions – all within a responsible and regulated environment.

Rule Over Our Online Slot Games Kingdom
Our online slots collection is a kingdom of creativity and craftmanship. With hundreds of titles spanning across every slot theme you can imagine, there’s always something new to discover at the king casino.
Prefer something simple and nostalgic? Our classic slot games bring back the charm of traditional one-armed bandits, complete with familiar fruit symbols and straightforward paylines. Looking for something with a modern twist? Our video slots combine immersive visuals, story-driven gameplay, and interactive features to keep your experience entertaining. And for those who enjoy a royal challenge, our jackpot slots offer pre-set or progressive pots that continue to grow until a lucky player triggers them.
Every game is fair, fully licensed, and powered by certified random number generators meaning every spin is completely random, every outcome independent. Our royal collection really has it all.
Online Slot Game Features
The beauty of online slot games lies in their variety. Yes, the gameplay is consistent, but each title puts its own spin on things (pun intended). Every slot game offers unique mechanisms, features, and bonus rounds designed to keep you engaged and entertained. Here’s what you can look forward to when you play slots online at Casino Kings:
Wild Symbols
These replace any other symbol (except for the Scatter) to help create additional win combinations.
Scatter Symbols
They trigger bonus features and in most cases, free spins. The more Scatters that land, the more Free Games you will receive.
Free Spins
Play extra rounds without using up your balance. You'll also find free spins offers amongst our regular casino promotions.
Multipliers
Boost your potential winnings with a set multiplier. Multipliers vary from game to game, from modest little bumps to larger multipliers.
Bonus Rounds
Some slot games offer mini-games or pick-and-win bonus features that add a little variety to your spin.
Jackpots
Choose from fixed jackpots or progressive jackpot slots - we've got them all. In some cases, landing certain symbols in the base game triggers the jackpot, in others you need to complete a mini game.
And if you like unpredictability, try our Megaways slots, where the number of ways to win changes on every spin.
How to Play Online Slot Games
If you haven’t played slots online before, don’t worry – they are one of the easiest online casino games to understand and enjoy. The setup is generally the same: you select the amount you wish to bet per spin, and then click the “Spin” button which is usually in the bottom right-hand corner of the game window. Simple.
The requirements for winning differ from online slot to online slot, but in most cases, you will need to line up three or more matching symbols along a payline. Each game has a different number of paylines and they take different patterns including a row, a zig-zag, a V shape and diagonally.
When placing your total bet per spin, it is an accumulation of the different bets on each payline. Your total win is each payline win added together. If you are looking for games with the most ways to win then Megaways slots are the best choice – standard Megaways titles offer 117,649 ways to win with each spin but some offer 1 million!

How Do Jackpot Slots Work?
Jackpot slots broadly fall into two categories – fixed jackpot slots and progressive jackpot slots. With fixed jackpot slots, the jackpot prize is pre-set and is always the same value. With progressive jackpot slots, the jackpot value increases as a small percentage of each player’s stake is added to the pot. Some of the biggest progressive jackpots have paid out £13m+.
