The advent of the internet gaming has breathed fresh life into an age-old pastime. Slot machines have been around since the 19th century, when bearded, pipe-smoking men (I’m generalising here) played them in the beer halls and alehouses across Europe and beyond.

Back then, you just pulled a lever to spin three spring-operated reels in the hope that three matching symbols appeared in a little window, and the prizes were modest, amounting to little more than a pack of gum or confectionary. Slot machines still exist in bars around the world today but are rather more elaborate. But it’s the development of online casino slots that has caused the biggest changes.

What Are Online Casino Slots?

Online casino slot games are inspired by the traditional ‘one-armed bandit’ games of yesteryear and share the same basic principles. You still ‘spin reels’ in an attempt to achieve a line of matching symbols that will secure a win. However, the possibilities of the digital world have provided design teams with free reign to be more creative than even the most modern ‘real-life’ slot machines could ever be. They use the latest animation techniques to create interesting characters, engaging stories, innovative in-game features and exciting bonus rounds that supplement the action.

Gone too are the days when only a straight line featuring three matching symbols represented a win. Most online casino slots feature loads of different winning lines, with diagonals, zig-zags and random interlinked formations all combining to give players more ways of winning than ever. Competition between design houses is fierce and the games continue to improve and evolve. That’s great news for online casino fans.

Why Are Online Slots So Popular?

Casino slots are vibrant, exciting, immersive and fast-paced yet really easy to understand. Unlike tactical card games, there are no clever rules to learn or ploys to adopt, which makes slots much more accessible to everybody. They’re popularity is further enhanced by their versatility. You can enjoy a concentrated session of play over a long period of time, gradually trying to build your pot of cash if you’re a slow burner. Alternatively, you can enjoy a few throwaway spins while on your lunch break or waiting in a queue if you want to dip in and out of a slot spinning session. This has also made them perfectly translatable to the mobile casino market, which has grown massively over recent years.

How Do Online Casino Slots Work?

We’ll go into more details about the mechanics behind mobile slots in other articles but it’s important to know the basics.

– Random Number Generators: Modern video slots use computers to generate numbers that dictate the outcome of a game. Each spin of the casino slot is a unique event that produces a new set of numbers, which are translated into the results you see on the reels. The fact that each event is unique means that there are no such things as ‘hot’ or ‘cold’ slots. Outcomes are not predictable; each spin has the same chance of creating a win as the next.

Return to Player Rates (RTP): All casino slots are assigned a Return to Player Rate. This refers to the amount a machine is expected to pay out to players and is usually expressed as a percentage such as 95%. Put simply, an RTP of 95% means that for every €1 gambled on a slot, 95 cents is paid out. However, this doesn’t mean every player will end up with the same result because the RTP is calculated over the game’s whole lifespan. One player might achieve an RTP of 200%, while another endures a 40% rate. Remember, it’s all randomised.

– Volatility: This refers to the frequency and size of the payouts you can expect from an online casino slot. Low volatility slots pay our frequently but in smaller amounts, high volatility slots pay out less often but in larger amounts. Medium volatility slots offer a bit both worlds. Your preference will depend on your playing style and budget. If you want to play longer sessions with lower risk, slowly building up your pot, pick low volatility slots; if you are a risk-taker seeking a big win or bust, try high volatility slots. Our in depth guide to how slots work will help you identify the right slots for you.

How to Play an Online Slots

Just like early slots, online video slots feature at least three reels and rows. All have at least three reels, but some can have four or five depending on the game. You win by matching symbols across paylines from a single spin, and you can adjust the amount you gamble to alter the amount you stand to win should the reels align for you:

– Coin Value: This refers to the actual monetary amount that you stake on your spin. It is measured per bet line. So, if a slot has 25 bet lines and you set a coin value of €0.10 then your total stake will amount to €2.50 (25 x €0.10). Lower your coin value to €0.05 and your spin will only cost you €1.25, but the potential returns will be lower too.

– Bet Levels: These exist on most slots and give you the chance to personalise your bet. Coin values are only available in defined increments, typically €0.01, €0.02, €0.05, €0.10, €0.20, €0.50, €1.00 and – on some games – €2.00. Bet levels give you the chance to multiply your coin value for a little bit more freedom. Set a bet level of 2 when your coin value is €0.02 and you will actually stake €0.04; set the bet level to 3 and you will stake €0.06. Those amounts are not available as coin values, which is where the bet levels come in handy.

Online Casino Slot Features

Online casino slots consist of reels and rows, just like the land based machines that inspired them. Most games use three reels, but some can have four or even five. The number of rows visible on screen can vary too, which can influence the number of pay lines.

In order to win, you will need to match a number of symbols on consecutive reels. Different symbols are worth different values, and you will need to check a game’s paytable to find out how you stand for each group of symbols. Most games also feature special symbols called wilds, which can mimic surrounding symbols to help create winning lines. You might also find scatter symbols in some slots, and they typically trigger special bonus rounds including free spins round. These are essentially ‘games within games’ that give you opportunities to enjoy some really thrills while boosting your bank balance. We’ll go into more detail about the features of slots in specific articles.
