Casino Wiki

So here it is, the Preferred Online Casinos Wiki Casino page (try saying that after a few beers). We’re really happy to bring you this section and intend to use it wisely. We’ll be posting all sorts. From casino jargon busting guides to tips and trick to troubleshooting and help articles. The idea is simple – to provide you with all the information you need to understand and enjoy playing at online casinos. Keep checking back for our latest posts, we hope you find the resource useful.

What Will You Find in Our Casino Wiki?

We’ve given you a little taster above, but let’s get down to the nitty-gritty. What can you expect to find in our Casino Wiki section? Well, online casinos are fun places but they ain’t half awash with lots of unique and weird words. If you want to understand casino bonuses or how slots work, then you need to know what these specific online casino terms mean. We’ll define the casino terminology for you and write some blog posts to help you understand more. Expect topics to cover questions like:

  • What are wagering requirements?
  • How do casino slots work?
  • What are wilds and how can they help you win on online slots?
  • What do you need to know about house edge?
  • What are the odds of winning the Mega Moolah jackpot?

Casino Wiki Sections

Those listed above are just a sample of the features you can expect to find in our Casino Wiki section. We’ve got loads of ideas and will look to split the Wiki section into different subcategories . This will mean you have a Casino Games Wiki section and a Casino Bonuses Wiki area. That should help you find your way around.

Online Casino Terminology

To start the section off, however, we thought it might be handy if we provided a short, sharp list of definitions for lots of regular casino terminology. Even seasoned players might not fully understand some of this casino jargon, and we’re determined to help bust it! The longer articles will provide you with much more information relating to these terms as we add them. But a casino glossary provides a nice bitesize reference point for you in the meantime.

Our Online Casino Glossary

Bet Level

Bonus Games

Games featured within online slots that offer you the chance to win extra cash and prizes. These games can take many forms and are often amongst the most attractive features of any given slot. They allow the game designers to get creative.

Coin Value

Deposit Bonus

A casino bonus that is awarded when a player pays some cash into his or her account. Can come in the form of free spins, free cash or other incentives.

Free Spins

Can refer t0 two distinct casino features:

  1. a) A type of bonus given away by online casinos. In this context, free spins are ‘free rounds’ that you don’t pay for. Typically, you are playing for real money although any winnings are likely to be subject to wagering requirements.
  2. b) A feature within an online slot game, which awards you free turns for a defined period of time. Free spins rounds are usually triggered by a particular combination of symbols and are often accompanied by other bonus features to boost your chances of winning when you use them.

House Edge

The statistical advantage that a casino has over a collective group of players when they play a particular game. The House Edge is essentially the ‘profit’ that a casino makes and is typically expressed as a percentage. Therefore, if the house edge for a given game is 6%, it means that the casino will ‘earn’ 6% of all the money wagered on the game over a prolonged period of time, with 94% being returned to the player (see RTP rates).

pretty accurate. If a game promises an RTP of 95% then €95 of every €100 wagered over time will be shared back to players. The remaining 5% is the house edge.

Local Jackpot Slots

Local jackpot slots are progressive jackpot games that are ringfenced for a particular casino. In other words, you can play the same for different jackpot amounts at different casinos. Only players who play the game at your chosen casino will contribute towards the jackpot for that site.

No Deposit Bonus

A casino bonus that is awarded without the need for a player to credit his or her account. They are frequently provided to new players to tempt them to sign up with a particular casino.


Patterns and combinations that are translated into wins when you pay an online slot. The most obvious payline is three matching symbols on adjacent reels. However, some online slots have hundreds of potential paylines, including various straight, diagonal and zig-zag combinations.

Pooled Jackpot Slots

Pooled jackpot slots, also known as network jackpot slots, are a type of progressive jackpot slot, which is shared by multiple online casinos. This means that a player who plays at one online casino will contribute to the same jackpot amount as a player at another online casino. The collaborative nature of pooled jackpot slots ensures that the prize pots grow to huge amounts.

Progressive Jackpots

A particular type of casino game where the jackpot on offer grows everytime somebody plays. This means that players collectively contribute to the development of the main prize pool. As and when a player scoops the big prize, the jackpot will reset to a default amount before growing again. There are two types of progressive jackpots – local jackpots and pooled (or network) jackpots.

Random Number Generator

A piece of software used to randomly generate numbers for an online slot. The numbers dictate the positions the reels after each and every spin, ensuring that no malevolent forces control your chances of winning. Your fate is entirely in the hands of the casino gods.


The wheels that spin when you play a slot machine game. Typically, reels appear vertically in a standard slot layout, as opposed to rows, which appear horizontally.

RTP Rates

RTP stands for Return To Player Rates and refers to the average percentage of all cash wagered on a game that players can collectively expect back over a prolonged period of time. It can be viewed as the ‘flipside’ of House Edge and is expressed as a percentage. Sophisticated coding controls the RTP rates of online slots so you can be sure that the results are always random.

Scatter Symbols

These rather nifty slot machine symbols will pay out no matter where they appear. You could have one in the top right corner, one in the middle and one in the bottom left corner, it doesn’t matter. Any combination of these ‘scattered’ about the reels wins a prize. They often trigger bonus and free spins rounds, as well as paying out in cash.


Also known as variance by some, volatility refers to the amount of ‘risk’ attached to any given game. Low volatility games will pay out more often but usually in smaller amounts, so are classed as low risk. You are likely to earn several, regular small wins to ensure you don’t lose too much cash. High Volatility slots will pay out less often, but will pay out greater amounts when they do. This means you could play for a long time without winning, thus putting yourself at greater risk of losing your cash. The possibility of winning a large amount is the trade off.

Wagering Requirements

Wagering Requirements refer to the amount you will have to bet in order to access winnings related to bonus money or free spins. Typically, wagering requirements are expressed in multiples of your bonus amount. So, if you have a €10 bonus with x25 wagering requirements, you will need to bet through €250 before you can access any winnings.

Welcome Bonus

A type of bonus given to players to encourage them to register with a new casino. Welcome bonuses can contain numerous elements, including no deposit bonuses, free spins, deposit bonuses and free cash.


A type of bonus symbol popular in online casino slots. Wilds behave like the Joker in a pack of cards and can substitute for other symbols to create winning combinations.
