Slot games are the majority of games available in online casinos. However, there are differences when it comes to their prizes and results. They are the easiest online game to play, and most bonuses are applicable to them. In this article, players can get to know the best online casino sites for slots and how to choose them.
Gambling N’ Go selection took into consideration the best sites for slots that would match the needs of players worldwide. From a combination of bonuses and free spins to great quality and reliable providers, those are the ones that caught our attention:
Spin Casino is one of those excellent online casinos for slots every player wants to find. Founded in 2001, almost 20 years of history allowed the website to continue developing its features.

Among exclusive games and the best titles produced by the best slots providers, such as Microgaming and NetEnt, Spin Casino players get new releases almost every week. That is, an excellent selection of over 600 games keep getting new addictive additions. Every single one of them can be played for free without any sort of commitment.
Of course, playing with real money involves the incredible deposit match bonus that sums $1,000 to new players. The downside would be their rather high wagering requirement, which demands players to dedicate some money and time before withdrawals. Fortunately, the payout speed can be as fast as the first 24 hours.
Finally, although there is no specific promotion, Spin Casino free spins can be acquired through their fortune wheel, available every 2-4 hours forever after the first deposit.

Slot machines began with what is currently known as video poker. It was developed in 1891, by Sittman and Pitt, with a total of 5 reels and 50 playing cards. We should thank the very first slot machine as we know it to Charles Augustus Fey, somewhere around 1887-1895. It had the 3-reel classic style we know so well, and only five symbols – replacing the cards.
The first online casinos started off in the mid-90s, not surprisingly bringing online slot games with them. It was not long until they became the most popular game genre in online casinos.
They evolved, bringing new features and adding in-game bonuses. Every week new titles are released by hundreds of different providers, among which a few dozen are well known by online players. Some great examples are Microgaming, NetEnt, and Playtech.
By the way, the very first jackpot slot came from Microgaming, named Cash Splash, with considerably high payments. Nowadays, Mega Moolah is the jackpot that owns a record payout of 17.9 million Euros.
Playing online slots is perfectly legal in case there is no legislation contrary to it in your country – or state, when the province has enough power to limit it, such as in the US or Canada. Therefore, our best recommendation is to check our section on each country’s relation with online casinos.
In general, countries that do not forbid playing slots online are accepted when registering to those online casinos. Usually, as long as the company is not established in your country, you can play slots and legally withdraw winnings.
Differently from machines, online slots are not tangible and therefore generate suspicion on players. However, we highlight the importance of the providers exactly because they are directly responsible for providing reliable slots.
The slot games, whether with a jackpot or not, count on an RNG (Random Number Generator) software that keeps generating random results – with or without players. Therefore, neither the casino nor the provider can control the following output.
Add that to the fact that the casinos operate in duly regulation, some audited by third-party auditing companies, and we can conclude they are safe games. Also, all deposits and withdrawals related to such slot games are also encrypted by SSL certificates, which keep your data hidden.

Perhaps some words in our guide or in the slot games do not sound familiar to some players. Therefore, here is a complete online slots glossary to help in such situations:
As a game that is completely free from skill requirements, slots are based on their volatility. Fortunately, slots can be divided according to how volatile they are, allowing players to decide the level of risk they want.
Most of the best casinos for online slots in our list identify the volatility of their games. We can separate them into low, medium, and high volatility. Basically, the lower the volatility, the higher the frequency of winnings – but they are proportionally smaller.
In other words, high volatility means less frequent payouts, but higher ones when you finally achieve them – which may happen from the first spin, as it is random. Therefore, low volatility can keep things less risky, but will not result in huge payouts.
Contrary to popular belief, volatility does not impact RTP. The combination of RTP and volatility will determine how fast you might get closer to the average payout. But, as we are talking about randomness and estimations, do not try to guarantee any sort of results from it.
Some slots will allow players to determine how many paylines (“lines”) they want to keep active. To keep things simple, whenever three symbols fall in sequence (usually the first left reel) over an active payline, the user wins something. Therefore, the fewer the lines, the smaller the area covered.
As it may be clear by now, the reels are each column on video slots with several symbols that fall at random. Nowadays, most online slots consider all rows of a reel for their paylines. Classic slots tend to have only 3 reels, but modern ones present 5, sometimes even 6.
The combinations that result in winnings must fall where a payline is traced, or nothing is added to the funds. Slots count combinations from left to right as a standard, and the first symbol must start from the first reel. However, some variations nowadays allow combinations from right to left too.
As for special symbols, online slots usually count on Wild and Scatter symbols. As explained in the glossary, they replace any other symbol and unlock features, respectively. When a game has a high RTP combined with many in-game bonuses unlocked by those symbols, it tends to be a good pick.
The winnings connected to each combination must be checked on the pay table of each slot game. As a rule, the more similar symbols added to the payline, the higher the payout.
Either by selecting slots on casino websites or watching videos or streaming of it, everyone already saw the acronym “RTP” at least once. It is highly important when picking a game, being more important than the design and features in it.
In short, it means Return to Player and estimates the house edge after playing for a long while – and still only an approximation. For example, an RTP of 98% means the house edge is 2% and what the casino would get from your bet in the long run.
Therefore, games with high RTPs mean the player may have a better payout at the end, which is as close to the estimation as a random game can be. Whenever possible, do not opt for low RTP games, but do not forget it depends on luck and how long you play it.
Finally, rest assured casinos cannot control the RTP of slot games thanks to their RNG software. Whatever is described as the RTP is the correct estimate for that title.
More importantly, it is essential to emphasize that no specific pattern increases the chance of winning a jackpot. After selecting a slot game with jackpot prizes, the player must check the game’s pay table. There, it should be indicated the minimum bet to win the jackpot.
Set the bet to the minimum necessary and simply spin. The jackpot is a random feature and depends on your luck. Besides, it may not work for bonus funds or not appear during free spins.
Many players who sign up to the best online casino sites for slots aim at jackpot games because of their huge prizes. As an inspiration and source of curiosity, we ranked the top jackpot prizes in online slots so far:
|Slot Name||Provider||Largest jackpot||Average period|
|Mega Fortune||NetEnt||£15,14 million||~70 days|
|Mega Moolah||Microgaming||£13 million||~120- days|
|Beach Life||Playtech||£5,4 million||~170 days|
The best slots casino should count on features that provide for the needs of each player. It is an individual decision, but GNG’s job is to make sure that it is made easier. Simply analyze our list and pick one that suits you well in terms of:
Minimum and maximum amounts that relate to your gambling activity, besides fast payout speed to your location.
The perfect combination of variety and quality makes it even better to play slots online. The more top-notch providers are there, the better. Being able to test games for fun is also a plus.
Decide if you prefer free spins or bonuses in the form of credits. Tournaments and special VIP rewards are also great additions to your regular deposits. Besides, always check wagering requirements.
Players may never need support, thanks to our complete reviews. Even so, it is important to know the slots casino of your choice offers great support channels.
Bonuses were mentioned several times in this guide as a recommendation for online slots players. They often duplicate or triple the first two to five deposits, and then recurrent bonuses can be activated in the majority of the best online casinos for slots. Therefore, understand the basics of each promotion type to identify your favorite.
One of the favorites to those who prefer to test an online casino and its games for real before depositing. A great example is the Slots Empire no deposit bonus, which can be activated with their promo code or via support channel.
In short, it adds credits to the account without any prior deposit. However, all withdrawals are bound not only to bigger wagering requirements but also to a minimum deposit afterward.
Another great bonus for slot players is the one that provides spins free of cost. As an example, we can mention the Casino.com free spins that allow over 200 plays as a bonus.
When free spins are credited, they usually last anything between 7 – 30 days and can be used on specific games – sometimes a single one, specified in the promotion. The wagering requirements tend to be calculated over winnings only.
Offered as a welcome offer and even in weekly or daily promotions, the deposit match bonus adds credits to the account that are proportional to deposits. Their percentage usually varies between 50% and 250%, depending on the casino.
El Royale Casino welcome bonus, for example, is one of the biggest in this list and is available to up to five deposits.
As a benefit of being a VIP player, users can get bonuses forever in their favorite casinos. That is usually given together with premium support and other advantages. Some casinos automatically add all their users to the VIP ranking; others make it exclusive, such as DreamVegas Casino.
The terms and percentage of it are usually equal to deposit match bonuses, or else some free spins may be given to users.
Before opting for any bonus, whichever the kind, it is highly important to understand its terms. Fortunately, our reviews here at GNG summarize what is divided across several pages of rules and conditions in five sentences. Basically, any player should look for the following information when it comes to bonuses:
While the others are self-explanatory, a bonus’s wagering requirement means how many times a bonus value must be played before withdrawals are allowed. Therefore, it will be obligatory to wager a considerable amount before withdrawing.
Fortunately, different from online blackjack games, slots contribute 100% to wagering requirements – with a few exceptions. Therefore, know upfront how much must be bet within a given period and make sure to finish it to avoid losing your winnings.
Tournaments are a great way to increase the possibility of being awarded something while playing slots. On the top of the normal pay table and the jackpot, users get cash and prizes for getting ranked on tournaments. Usually, it is necessary to opt-in, and most tournaments are free to enter.
To win, make sure to bet and participate in the specific games whenever possible and more than your opponents.
There are players who prefer to bet high, as that is how the highest possible payouts are awarded. Therefore, we also made a specific table for them, with the highest bet limits in online slots:
Slot Name Highest Bet Piggies and the Wolf £2,500 Ghosts of Christmas £1,200 Santa Surprise £1,000 Age of Gods: Goddess of Wisdom £1,000 Zhao Cai Jin Bao £900
Now we are familiar with RTP’s concept and how valuable that percentage is to define the payout of slot games. Next, let us reveal which online slots found in the best online casinos count with the highest payout among their genre:
Slot Game Provider RTP Ugga Bugga Playtech 99.07% MegaJoker NetEnt 99.00% Ooh Aah Dracula Barcrest 99.00% Jackpot 6000 NetEnt 98.86% 1429 Uncharted Seas Thunderkick 98.6%
When you play slots for free, fictional credits are added to the balance, allowing unlimited spins – only reset it if the funds are gone. That is a great manner to test a game and get used to it, besides discovering its features and bonuses.
On the other hand, it is impossible to collect any winnings from free play. It is necessary to use real money or at least a bonus in the real gameplay mode. Therefore, in order not to get frustrated with a big win that cannot be collected, start playing for real as soon as you find your favorite slots.
Besides, after activating any bonus, prefer to use your time to bet with real money. There usually is a limited amount of days to use the bonus and complete the wagering requirements.
Online slots allow people to play from wherever they are, as long as they have a proper internet connection. Besides, they can be accessed via any device, from computers to smartphones. However, that is not the only contribution of online slots to the gambling world.
Some countries do not allow land-based casinos, and therefore people can only rely on online slots. Otherwise, only on a trip could they ever experience the thrill of playing slots.
Also, it is within online slots that lie the best in-game features and free spins. Not to mention the additional bonuses that only online casinos can provide. On the other hand, real slot machines are always a great experience together with the casino ambiance, and everyone should try it at least once.
The main advantage players love in online slots when compared to other casino games is that they are the kings of bonuses. With a few exceptions, they usually contribute 100% to wagering requirements. Moreover, they count on a series of exclusive bonuses, such as free spins.
Leaving bonus aside, some casino games are rather complex when it comes to rules. Slots are practical and demand nothing but a single tap on the screen. If the player picks a low volatility one, the spins may last for hours without much of an investment.
The spins are also rather fast, and each play may literally take a couple of seconds. Add to that the fact that some online casinos have thousands of slots, and it is almost limitless fun. Fortunately, our selection of the best casinos for online slots counts with both quality and variety.
Of course, each casino game has its appeal and benefits, but it is impossible not to agree with the facts above.
We identified the top slots providers, among over a hundred options, so that finding top-notch slots is no longer a tedious activity. Together with the information features of websites such as Slots Empire, it will be easy to recognize those worth playing for real money:
