A progressive jackpot takes a small percentage of every bet made, from all online casinos around the world, and put it into a constantly growing jackpot. Some games will award the jackpot at random, while others require a specific symbol or symbols on the reel to trigger the win. The latest trend is for several games to create a single progressive jackpot. You can find this in the Age of the Gods, DC Super Heroes, and Kingdoms Rise groups of games. The record-breaking progressive jackpot comes from a single game, Mega Moolah, and it paid out over 21 million pounds. Check out the progressive jackpot page at Casino.com UK for more information about the best progressive online slot games.


Here are some key terms for punters to know before playing online slot games.

  • Bonus Feature and Spins: One of the more exciting aspects of online slot games are extra features that can either be triggered at random, or by landing several bonus or scatter symbols. The features can range from free spins, pick-and-click games, a new set of reels with different symbols and much more.
  • Fixed Jackpot: Unlike a progressive jackpot that grows with each spin, a fixed jackpot is usually based on a paytable and has a set payout.
  • Multiplier: This will increase the size of a win by the multiplier. For example, £2 win with a 3x multiplier will payout £6
  • Maximum and Minimum Bet: All online slot games have a minimum and maximum bet that you can wager per spin.
  • Return to Player (RTP): Based on thousands of games, the RTP is the average expected return to the punter. The average RTP is around 96.5%, which means that if you played with $100, you could expect to finish playing with $96.50. It’s important to note that the RTP doesn’t guarantee that you’ll end up with 96.5% of your, where’s the fun in that, but if you took a look at all the punters playing this game, that would be the average return.
  • Grid vs. Payline: These are the two main types of slot games. A game with a set number of paylines will require that symbols are aligned on that payline to create a win. In a grid, or Ways to Win system, the matching symbols just have to land on adjacent rows to create a win.
  • Payout: This is the value of a symbol, the more symbols you have in a row, the higher the payout.
  • Reels: This is taken from the one-armed bandit slot machines that had 3 reels with the symbols on them. Online slot games don’t technically use reels in the mechanisation but kept the terminology.
  • Scatter: A symbol that pays out without having to be along a payline or on adjacent reels. Scatter symbols can often only appear on certain reels and can trigger a bonus feature.
  • Volatility: Also known as variance, this is a way to measure whether a slot game will pay out small wins frequently or has bigger wins but less often. A game with a high volatility is considered a higher risk than low volatility games since they don’t pay out as often.
  • Wild: It can substitute for any regular symbols to create a win. Some slot games have special wild symbols that can expand or multiply, but that depends on the specific game.

With hundreds of online slot games, each one a bit different from the others, it’s understandable if you have questions about the rules or features of a specific game. There are two main ways to find answers to your questions:

  • In-Game Help Menu: Every game has a detailed help menu, that will go through every aspect of the game. For some games, you’ll have to click on a “Hamburger” button for others it’s a “?” icon, but whatever the button is, you’ll be able to find the paytable, bonus features, odds, and even your betting history.
  • Customer Support: If your question is on the technical side, regarding deposit and withdrawal, or any other issues that require the assistance of a real person, many online casinos have a dedicated Customer Support Team or you to contact. They can be reached via phone, email, and Live Chat.


How do you win at online slots?

Whether you’re playing in a payline or grid style, to win at online slots, you’ll need the symbols to land in a certain formation to trigger a payout. There are some features and jackpots that can be awarded at random, but this will vary per game.

Do online slots remember you?

Yes, most online slot games have a year long memory. This is especially important in games like Ghostbusters: Level Up Plus, which has 10 levels, or the Kingdoms Rise suite of games, where you can win special coins that can be used to purchase bonuses at the “Store.”

How do online slots payout?

Any time you get a matching set of symbols in a winning combination, it will trigger a payout based on the value of the symbol. The paytable will typically be based on the line bet, as opposed to the overall bet. What this means is that if you’re playing a 20 payline game,  make a bet with a  £1 coin, meaning your total bet is  £20  and get 5 symbols in a row with a payout of 100x the payout will be  £100 as opposed to  £2,000.

What is a Flat Top slot machine?

Unlike progressive slot games that have a constantly changing jackpot, Flat Top machines have a fixed top jackpot.
