Below we explain a few terms and aspects of slot machine game play that some new gamers can sometimes find confusing and at the foot of the page you'll find a quick fire Frequently Asked Questions section that tackles everything you might want to know about slots or pokies as they're referred to in the southern hemisphere!
Variety in Slots
There are three general types of slot games that you can find online and we've tried to provide players with an insight into what makes each type worth trying out.
Video Slots - often more cinematic in their approach, video slots usually come with a range of extra features and bonus rounds that can include things like pick'em bonuses, free spins and mini-games. The 'Video Slot' is a broad term that encapsulates any modern slot with eye grabbing graphics and animations.
Classic Slots - 3 Reel Slots are the oldest version of the game and fall into the category of 'Classic Slots'. 3 reel slots date back to the 1950s and nearly all examples have a single pay line. 3 reel slots offer punters the opportunity to win big money for relatively small stakes and are popular for their simplicity.
Progressive Jackpot Slots - Progressive slots are part of a games network where the prize pot accumulates across a number of sites and bumper jackpot prizes are available to some lucky winner that'll bag the potentially life changing big prize.
What is slot game RTP?
RTP is short for Return to Player and is a percentage that essentially tells you how much of the money put in by players over time will be paid back to them. This figure is worked out over the lifetime of the game and so can take into account both good and bad periods, it's not just an average.
High Volatility
A slot with High Volatility pays out less frequently but pays out big when it finally drops.
Low Volatility
If a slot has Low Volatility it means it pays out often on a smaller scale. In other words, high volatility slots offer higher rewards for smaller wins, while low volatility slots offer lower rewards for bigger wins.
Slot Machine Bonus Features
All video slots come with bonus features, most have many. The bonus round is a part of the slot's gameplay which offers players special features and chances to win additional prizes that are separate from the main game.
The most popular slots use wild symbols that substitute for others across the reels to complete winning combinations, they also tend to offer scatter symbols. Scatter symbols are the least demanding in terms of triggering wins, you simply need two or more to appear anywhere on the reels to win. A 'Free Spin' is a pre-determined number of free spins offered by an online slot.
Slot Tournaments
Slot tournaments are something that has really taken off in recent years, they're a lot of fun and depending on the casino you play at it'll cost you either nothing or next to nothing to enter one. Slot tournaments are a race against other players to see who can achieve the best score over a set number of spins. The winner is usually the person who ends up with the highest amount of money in their account. Some casinos offer juicy prizes and rewards for their slot tournaments and playing them can add an extra dimension of entertainment to your time gambling online.
