We list and compare the number of online slots available on each casino, the average payout, and which top game providers are being used such as NetEnt and Microgaming.

How to Play at Indian Online Slot Casinos

Sports betting is popular in India, but a lot of people also enjoy playing at Indian online slot casinos due to the wide range of casino games on offer.

Playing at these sites is quite simple, with many of them also having mobile casino apps to make it possible to play online casino games while out and about or on the move.

Signing up for an account is the first step towards playing at Indian online slot casinos. This is usually a quick and simple process that should not take longer than a few minutes.

The site will ask you to fill in a short form with details such as your name and email address, while it is likely you will need to verify your account through an email you receive too.

After this, you will be ready to deposit into your new online casino account. To do this, choose the banking method that you wish to use and follow the on-screen instructions.

Once you have successfully added cash to your chosen casino site, you will be ready to start playing online casino games such as slots and hopefully winning plenty of money.

How We Choose the Best Online Slots Sites in India

As we mentioned earlier on, there are a lot of online slot casinos out there in India, and there are a few things that an Indian slot casino site needs to win a recommendation.

First up, players from India obviously need to be able to access the site. While there is a lot of confusion over the rules and regulations around online gambling in India, there is nothing actually stopping players from joining casinos that welcome people from India to sign up.

It is also a must for Indian online casino sites to allow players to deposit and withdraw in Indian currency. Perhaps surprisingly, not all online casinos do this.

Being able to play in rupees is a must as strict rules surrounding foreign currency in India. Therefore, playing at online casinos in another currency, and then transferring the money into rupees, could put Indian casino players at risk of breaking the law.

On the subject of banking methods, speed is of the essence when it comes to making withdrawals from an Indian online casino site. Players hate having to wait for their winnings, so sites that can promise the fastest withdrawal speeds are always going to be in high demand.

It might also be useful if an online casino also has a sports betting site attached. With Indians so keen on sports betting, particularly for cricket, having both options can be a big tick in the box.

Bonuses and free bets are also vital for people thinking about joining online slot casinos in India. Sites make a range of offers available in a bit to tempt people to sign up for them. With so much competition out there in the industry, promotions are getting increasingly generous.

There are various types of bonuses offered, such as deposit match bonuses, free spins and no deposit bonuses, so there is plenty of choices out there.

The best online slot casinos below are entertainment hubs where you can gamble legally while enjoying lucrative welcome bonuses. You can explore and enjoy and enjoy a wide-ranging array of slot games at these casinos, which will undoubtedly give you an immersive gaming experience.

Just like that, you can find several benefits of playing at a top-ranked Indian online slot casino. However, India now has numerous online casino sites, and it’s hard to tell which one is the best fit of all. Knowing the best options is always a smart decision, and our review guide will help you with that.

How Online Slots Work

Many players suggest online slots are rigged or fixed and that can be true, but it is not the case with all of the online casinos on BettingGuide.com. Each online casino is independently tested to ensure all the games are fair.

Every online slot game uses a random number generator (RNG) computer which creates random sequences to ensure the slot is fair and not fixed. Each spin of an online slot is completely random, and the previous spins do not affect the result in any way.

Also, some players suggest online casinos can influence the results to alter payouts or other factors, but this is simply not true. Online slots are built, developed and provided by third-party gaming companies such as Microgaming or NetEnt, and online casinos have no control over the games. Also, these RNG's are routinely checked by independent companies to ensure a fair playing experience.

Different Types of Online Slots

Online slots have come a long way, and there are now several different variations available to players. They are all still run through Random Number Generators, but they can be designed in different ways to create different gameplay styles.

India's best online slot casinos often focus specifically on this type of game at the expense of others. There could be dozens or even hundreds of slot games available to try out.

Slots can come in all sorts of shapes and sizes now with different types offered. There are 3D slots, video slots and slots that are based on popular films and TV shows like Game of Thrones.

Classic casino games such as roulette and blackjack are also commonly available. Within this, there are likely to be a few different options when it comes to both roulette and blackjack.

While the game is ignored in some countries around the world, baccarat is huge across Asia. Easy to play and with a very low house edge, it is simple to see why people love baccarat. This makes baccarat one of the top games to play at India's best online baccarat casinos these days. 

3 and 5 Reel Online Slots

The 3 reel online slots also known as classic slots are for people that like to keep it simple. Reels are the vertical sections that roll with each press or pull of the lever, and the 3 reel slot was the traditional build for slot machines.

Just match the symbols along the top, middle or bottom line to win, or even just the single pay line that runs through the middle on the simplest of 3 reel slots. Some 3 reel online slots are built with an old-school look and sound just like a traditional fruit machine that you could find at a traditional casino.

Most online slots now offer 5 reels and tend to be more visually attractive and entertaining. The increase in reels also increased the pay line possibilities with potentially higher cash prizes.

Progressive Online Slots

Progressive online slots are games in which the jackpot increases by a small amount every time you spin if it is not won during a game. Progressive jackpot slot games are very popular casino games with the chance of winning massive jackpots.

Most progressive online slots increase from players all around the world playing at the same time and contributing to a huge prize pool for one lucky winner.

Mobile Online Slots

With the increase in dependence on our mobile devices, online gaming companies started to develop mobile-specific online slot games for players to play on the go.

These slots games have been specifically created to play on smart devices such as phones or tablets while not decreasing the visuals from playing on a smaller screen.

Online Slots Variations

There are thousands of different slot games out there, across all types of genres, such as sport, movies, TV shows, animals, fantasy, magic and many more.

The chances are that if a player can think of an idea for a slot game, it has already been done and can be played at a slots site in India.

But a handful of slots are considered to be among the best around, due to reasons such as sheer playability, payout percentages, design and fun factor.

Here are 10 of the top online slot games that players at Irish slots sites should consider trying:

Starburst: This five-reel, three-row video slot might be the most famous game of its type in the world right now. Always a popular choice at online casinos, Starburst is a NetEnt game that is always an engaging selection to play due to its strong range of bonus features. Even though Starburst is a few years old now, it still looks modern and is expected to remain popular for a long time to come as a result of its combination of solid RTP and low variance.

Mega Moolah: Famous for making millionaires of slot game players on a regular basis, Mega Moolah is probably the top progressive jackpot game in the world. Mega Moolah often sets new records when it comes to winnings from a single spin of the reels, making it a huge hit for Microgaming. The African wildlife themed game has paid out over £1 billion in winnings.

Book of Dead: Play'n GO title Rich Wilde and the Book of Dead has spawned a few sequels from the operator, as well as imitations from other developers in the world of online slots. High volatility gameplay means there is always a lot of excitement for those who choose Book of Dead at their favourite online casino site. Other games in the series include Rich Wilde and the Tome of Madness, Rich Wilde and the Pearls of India and Rich Wilde and the Aztec Idols.

Gonzo's Quest: Another slot from NetEnt is up next, with Gonzo's Quest without a doubt one of the best games to play at online casinos right now. Gonzo's Quest is nothing short of a casino classic, with its 3D graphics standing up to scrutiny despite the age of the slot. Gonzo's Quest has a total of 20 paylines and its avalanche feature keeps players coming back for more.

Cleopatra: IGT title Cleopatra is known for its large payouts and bonus games. Even though it is now about 15 years since Cleopatra was released on to the market, it remains popular now. The old-school design of this slot game is in contrast to the bells and whistles of modern slots.

Rainbow Riches: This slot game from Barcrest is among the most famous in the world, even though its RTP is quite low compared to many other options at online casinos. With a leprechaun theme, Rainbow Riches might be an obvious selection for Irish casino players. The unique bonus features are among the reasons why Rainbow Riches is considered an elite slot.

Age of the Gods: No list of the best online slots to play would be complete without a mention of Age of the Gods. This game from Playtech has sparked a wide range of sequels, becoming a juggernaut for this slot developer. Age of the Gods has a progressive jackpot while multiple bonus features have been included to increase the repeat playability of the game. Many different Age of the Gods games have now been released by Playtech to online casino sites. Among the best of them are Age of the Gods Norse: Ways of Thunder, Age of the Gods: Medusa & Monsters, Age of the Gods: King of Olympus and Age of the Gods: Furious 4.

Jammin' Jars: The garish design might not appeal to everyone, but Jammin' Jars has found an audience at slots sites around the world, including in Ireland. Jammin' Jars - which is made by Push Gaming - has an RTP of almost 97%, which means it offers great value. This 3D video slot has an unusual layout, with the reels laid out in an 8x8 grid, while cluster wins offer something a bit different to most of the other top slot games that made the cut on our list.

Twin Spin Megaways: NetEnt's slot Twin Spin was one of the top slots of all time, but its successor Twin Spin Megaways might just be even better. Twin Spin Megaways offers up to 117,649 ways to win, with its top features including symbol cascades.

Immortal Romance: Our final pick of top slots to play at online casinos is Immortal Romance, another game that comes from the expert developers at Microgaming. There might only be five reels, but Microgaming has cooked up 243 ways to win on this slot game. Immortal Romance was launched in December 2011 to coincide with a boom in vampire products.

How Online Casinos Get Their Slot Games

Some people who play at online casinos in India might be surprised to learn that these sites do not develop their own games.

Instead, they tend to license them from third-party companies, some of which we named above in our selection of top slots to select at Indian casino sites.

One of the reasons for this is that developing slot games is much more expensive than most would guess. It would not be feasible for an online casino to develop its own games.

Instead, developers sell their games to slot sites and they also usually take a cut from the money that is made by people playing the game at online casinos.

A number of online casinos also have exclusivity deals with developers. This means that the games are only available to be played on those sites, which costs them a premium fee.

It is also common for online casinos to have special tie-ups with developers that mean only their games are offered.

Developers usually also create online casino software, which means an operator can bundle everything into the same platform, which is usually cheaper and easier.

Popular Online Slot Providers

Slots casinos are likely to feature games from a wide range of providers. Some companies are better known than others, but even smaller developers can produce fantastic slot games.

With that in mind, here are 10 of the most popular slot providers at online casinos right now:

Microgaming: Claiming to have developed the world's first true online casino software in 1994, Microgaming has long been one of the industry's most important companies. Microgaming was also a pioneer in the launch of the first mobile casinos, having launched its software in 2004.

NetEnt: Swedish studio NetEnt has been one of the most popular slot providers in the world for many years. Founded in 1996, NetEnt produces all types of casino games but has a strong focus on slots. Over 200 online slots have been released on to the market by NetEnt so far.

IGT: International Game Technology is one of the best known casino game providers in the world, with a long and proud history of slot development. IGT has been around for decades but the release of a new game from this slot provider still provokes a lot of excitement.

Novomatic: A range of video slot classics are available from Novomatic, with Book of Ra, Sizzling Hot and Lucky Lady's Charm some of the company's biggest hits to date.

Playtech: Founded in 1999, Playtech is now one of the most popular slot providers in the world. At the end of 2019, Playtech launched an industry-first, with its Live Slots potentially offering a glimpse of the future of online casinos. Age of the Gods: King of Olympus is one of the best Playtech slots that is available to play at online casino sites.

Play'n GO: Specialising in high variance slot games, Play'n GO has grown into one of the most popular slot providers around over the course of recent years. Play'n GO titles include the huge Rich Wilde series, which has spawned a wide variety of imitations across the industry.

Pragmatic Play: A leading provider of slot game content for online casinos, Pragmatic Play hits include Wolf Gold and Dog House. Despite only being founded in 2015, Pragmatic Play games can be found at most of the top online slots sites, with the company continuing to grow.

Yggdrasil: Slots from Yggdrasil are known for their incredible design, with progressive jackpot games among those produced by the developer. ‎Valley of the Gods is one of the top online slot games to have been released by Yggdrasil, with Holmes and the Stolen Stones up there too.

Quickspin: Another Swedish studio operating at the top of the online slots industry is Quickspin, a company that focuses on quality rather than quantity. This means that Quickspin does not release nearly as many new slot games as other providers, but they are always worth trying.

Realistic Games: Last on our list of the best online slots providers is Realistic Games, a leading casino content developer. Realistic Games is the company behind the hilarious Hot Cross Bunnies game, with the UK-based firm also producing games like Take Note.
