Guide to Online Slot Games 

It’s so easy to play slot games online! In fact, playing slot games online can be even easier than playing slots at a brick and mortar casino, as you can access online slot games pretty much wherever you are, whenever you feel like it. The majority of slot games are optimised to play on desktop, laptops, tablets and mobile, so you can play on any device which is easy for you, making playing slots extremely simple!

One reason players love playing slots is that you don’t need any practice or to employ any advanced gambling strategy to have fun and be in with the chance to win money with slots. A beginner has just as much of a chance of winning as a player who has played the same slot game hundreds of times as the outcome of the spin of a slot is completely random, making slots ideal for just about every player.

Slot Mechanics Explained: the RTP, RNG and Paylines

Playing slots is super simple, but some beginners get a little bogged down with some of the terms and jargon used in slots like RTP, RGN and Paylines. But before you slowly back away, knowing what these terms mean will help you to play slots and understand how they work! To get the hang of them you can also try some demo slots.

Random Number Generator

RGN stands for a random number generator, and it describes the mechanism of how a slot game works to generate the symbols you see when you spin the reels. As the name tells you, the numbers are generated by a digitalised device at random, which means that which symbols will appear on the reels are completely random and dictated by the random number generator, making them unpredictable. By using RGN, slots are fair and players can rest assured that slot games aren’t fixed!

Return to Player

Another acronym that players are often unsure about is RTP but understanding what it is will help you understand how you can win whilst playing slots. RTP stands for return to player and it describes the theoretical percentage of a slot game paying out following a certain number of spins over the course of an extended period of time. An RTP is displayed as a percentage and essentially, the higher the percentage, the better as this means that theoretically, the slot game will pay out more often than slots with a lower percentage. All RTP percentages are generally displayed in the game descriptions, so you can use your judgement to work out which games are more worth your while!


A payline can also be known as a betting line and they are a combination of symbols which result in a winning combo in a slot game – so you’ll soon find out what a payline is while you play! Paylines can come in a variety of shapes and sizes depending but on average slots have 25 or so paylines but there are some games that can have hundreds of paylines. Some are fixed which means that all will be active during the gameplay, but others you have the options to choose which paylines you wish to play on.

Slot Games with Jackpots

For a lot of players, it is a great part of the experience when playing slots to have the chance to win life-changing sums of money, and the best possibility to do this is to play online jackpot slots and the good news is they are in abundance and there are so many different kinds of jackpots slots available to play including games with local jackpots and progressive jackpots.

Progressive vs Local Jackpots 

Slots can have different kinds of jackpots up for grabs for lucky players, including progressive jackpots and local jackpots. What’s the difference? Let’s start with local jackpots. Local jackpots are jackpots that are localised either to a certain casino and the games are interlinked to crease a jackpot which is the sum of all the prizes from the individual slots. These are great if you’re looking for smaller jackpots with a more regular win rate, but if you’re looking for bigger prizes, progressive jackpots are the way to go.

Progressive jackpots can yield huge prizes and the thrill of knowing you could be in with a chance of winning mega jackpots can make the experience extremely fun. With progressive jackpots, they start out with a base value which is the starting point for the jackpot which is then progressively built upon as players place their bets. This base value is the lowest the jackpot will go, and it is usually still a generous jackpot figure! Each time a player places a bet on the slot which is linked to a progressive jackpot, a small amount of this wager is then pooled into this progressive jackpot, meaning the jackpot is progressively grown from the base value and will continue to build until one lucky player hits the jackpot. This, as you can imagine, makes progressive slots extremely interesting to players! Once a player has won the progressive jackpot, it will then revert back to the base value jackpot for it to then be built up again.

Slots Games History

To understand how slots work and how to win at slots it’s good to know a bit of history around slots and to bust some myths around slot games! One common misconception about slots is that they have a clockwork mechanism and that they can be manipulated. This hasn’t been the case since the 1960s when slots were literally wound up by casino operators as they didn’t even use electricity. These slots were well known for being able to be manipulated but from the 1960s onwards slot machines benefitted from advancements in electromechanical technology and were upgraded to use electricity to run which made them less easy to be manipulated by players. Advancements in technology thankfully continued and as we waved goodbye to the 80s welcomes brilliant technologies in 1990 which made use of cutting edge (at the time!) video technology and computerised coding to make slot machines run.

It didn’t take long for players to try and hack into these new video slots and one infamous programme hacker who used Blackfoot slot code to manipulate slot machines was Ronald Dale Harris who used his skills as a programmer to hack the system so he could predict the outcome of the slot machines accurately. Harris was of course caught in the act and was subsequently arrested, but this also meant casinos were wise to this back foot coding technique and further advancements in technology enabling casinos to change to a central server meant that slots were always fair for all players as they were unable to be manipulated!

How to win at Slot Games using a Strategy

Now you’re clued-up on the rich and exciting history of slots, I’m sure you’re more than interested to find out how to win whilst playing slots, am I right? Well then, let’s take a look at some top tips from expert slot players on how they are victorious on the reels.

To increase a chance, you could try placing higher bets which will maximise your winnings when they come around. Because of how slot machines work, it’s impossible to accurately predict when you will win or how to influence the slot machine as they are controlled by a digitalised random number generator. So, one way to ensure you cash in on when you do win is to play higher denominations, after all, the higher your bet, the higher your payout will be if you do win, meaning you can capitalise on your win. Of course, this comes with a caveat of – bet in accordance with your own budget and only bet what your bankroll will allow. This way, any winnings will be a bonus and you’ll still be playing within budget.

Another brilliant piece of advice from experienced slot players is to always play games that you enjoy and find easy to play, that way you’ll always have fun even when you don’t win – which will make you a real winner! Mind-set is very important and when playing slots it’s good to remember that you’re playing for entertainment and that any winnings are a bonus. It’s also important to know that just because a slot is simple doesn’t mean you can win big and just because a slot is complicated with an array of features doesn’t necessarily mean you have a better chance of winning. Check out the game description for the RTP percentage before you play a slot game, as this will give you an idea of the theoretical payout rate to help you decide which slot to play.

Always Gamble Responsibly 

Gambling is best enjoyed responsibly and the best way to do this is to be in the right headspace when you’re playing. Above all, the most important thing is for you to have fun when you’re gambling, but if you start to show signs of feeling frustrated, angry or stressed when you lose, it could be time to take a break. Gambling is all about enjoying the experience within your own limits, so take regular breaks so you aren’t playing for an extended period of time and stick within your own bankroll so that you never spend more than you can afford to lose while playing. Happy spinning!
