What Are Online Slots?

A slot machine is a gambling game that includes symbols, multiple reels, and sheer luck. Based on the position of symbols landed on reels, you can win or lose your stake amount.

Types of Real Money Online Slots

Today, most gambling sites in Ireland will provide multiple slot machine versions for their players. Different games will come with varying features and benefits.

But it is essential to know about the popular slot categories currently in operation in the gaming industry. Here are some of the standard slot machine versions you can play online.


The three-reel slot machine is the original version that Charles Fey invented. Some of the common symbols you will encounter in this slot will be wilds, aces, or lucky horseshoes.

You need to fix the coin value and land three matching symbols in the adjacent reels.


The five-reel slot machine is much like a 3-reel version but with 5 vertical columns instead of 3.

Usually, a 5-reel slot machine will offer 20 pay lines, thus offering more chances of hitting winning combinations. Here, you will get to experience some of the best animations and graphics.


If you are looking for high-paced entertainment, a video slot machine is where all the fun's at. You will find a wide range of video slot machines based on different themes, movies, or rockstars.

You can also call them a modernised version of the classic slot machine with improved graphics and soundtracks.


Innovative technology has made it possible to feel like a part of the gaming world while playing it. For an enhanced, immersive experience, gaming providers have developed 3-dimensional slot machines.

Here, you will see slot machines with photo-real animations and the best of lifelike characters and symbols. Most slot machine versions on online casinos today are 3-D.

Progressive Slots

A certain percentage of the bet amount is contributed to the jackpot in this slot machine. When a lucky winner scoops up the pot, the current value is paid, and the amount is reset.

The game providers pre-determined a fixed minimum value for each jackpot.

Mobile Slots

Hoping to turn the wheels while at work or travelling? It is now made possible by the increasing number of mobile slot machines.

Game developers have ensured complete mobile optimisation and launched multiple versions, especially for smaller screens. Such slot machines are equally compatible with Android and iOS.

Mega Spin Slots

A mega spin slot machine includes a series of 5 games with different screens. Here, you are not just playing 1 game, and each spin triggers the other one.

Such versions were launched initially by Microgaming and are pretty popular in the gaming industry. Needless to say, such games increase your odds of a win.

Multi-Payline Slots

Multi pay line slot machines make online gaming even more fun. Here, you have more symbols and lines.

The pay line can vary from adjustable to fixed and provides players with extra spins and fortune wheels. You will need to increase the stake amount, which drastically increases your chances of winning.

Online Slot Machine Game Features

Game developers regularly launch new, interactive features to make the gaming experience even more exciting and engaging. Some standard features to look for in online slots are:


Wilds can randomly replace your regular symbols and turn the reel into a winning combination. An increased number of wilds implies that you are claiming more rewards and the amount won in the end.


Also termed as the player’s best friend, a scatter symbol can trigger an extra spin round and prizes in the slot. With scatters, there’s no specification regarding the reel position where the symbol should land.

Free Spins

Free spins give you a chance to land the winning combination without having to bet any amount. Primarily, such spins are included in the bonus but can also be a separate slot feature.

Bonus Rounds

Apart from the base game, you can also play the bonus rounds. According to the game, you can win this round by landing bonus or scatter symbols 3 times in a reel.


You also have the chance to watch your winning amount multiply with the help of a multiplier symbol. Based on the slot machine, it might range between 2x to even 1000x.

Understanding Online Slots Payouts and RTP

Each slot machine comes with a publicly known fixed RTP value. RTP stands for Return to Player, and it helps determine the amount any particular gambling machine will give back to the player in a set duration.

With the help of RTP, players can calculate the winning odds and estimate payout value. For example – if the slot offers 95% RTP, it implies that with every €100 spent by the bettors, the machine gives back €95 only.

However, in a two-player scenario, this could also mean that a single-player grabbed the €95, while the second one lost all the bet amount. On average, the RTP value of electronic gambling machines is around 96%.

Anything lower than that would classify as a low RTP, and values greater than 96 would be considered high. Some high RTP slot machines are Ugga Bugga by PlayTech with 99.07% and Ooh Aah Dracula by Barcrest with 99%. For beginners, it is better to stick with a high RTP slot machine.

Online Slot Machine Bonuses

Any online slot machine or fruit machine aims to offer players lucrative offers. Based on the gaming developers, rewards types may vary, but such features mostly revolve around the set industry standards. Commonly found online slot machine offers are:

Deposit Match Bonus

Here, the online slot machine will match your coin. It means that for a 100% deposit bonus, you get the same amount bet from the company end.

As a result, you now have double the original amount to start betting. Such an offer is usually included in the welcome package.

Free Spins

You can utilise free spins to hit the right combination and strike big without betting any amount from your end.

The slot machine will offer you spins either randomly or with specific promotions. Usually, spins are delivered in batches, i.e. 10 or 20 each day and are valid only for 24 hours.

Cashback Bonus

If you are worried about losing your amount while spinning the slot machine, here's another feature to make things simple for you.

If you end up beating the odds, you get the set amount. But if you end up losing, a certain percentage of stake is credited back to your account.

No Deposit Slots

Gambling comes with plenty of risks, and as a result, a player might not want to deposit any real cash. A no deposit offer allows you to stake a portion of the bonus itself and continue betting.

However, you will need to wager the winnings as specified in the guidelines to withdraw.

Slots No Wagering

Usually, the slot machine will ask you to wager your winnings a fixed number of times before withdrawing the amount.

However, slots no wagering implies that you can cash out without betting the won amount. Such a bonus is usually quite on the lower side.
