We mentioned bonuses several times in this guide along with our recommendations for online slots players. Bonuses often double or triple the first two to five deposits; recurring bonuses can be activated in many of the best online casinos for slots. Therefore, understand the basics of each promotion type to identify your favorite.
A bonus offered to new players without the need to make a deposit. It can come in the form of free spins or bonus money.
A bonus that awards a certain number of free spins on a specific slot game or a selection of games.
A bonus offered to new players when they first sign up for an account with a casino. It can come in the form of a deposit match or free spins.
A bonus offered to VIP players with special perks and benefits. It can come in the form of personal account managers, exclusive promotions, and higher withdrawal limits.
Before opting for any type of bonus, it is highly important to understand its terms. Fortunately, our reviews here at GNG summarize what is explained across several pages of rules and conditions, in a few 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 certain amount before withdrawing.
Fortunately, in contrast to online blackjack games, slots usually contribute 100% to wagering requirements – with a few exceptions. Therefore, learn upfront how much you must bet within a given period and make sure you can accomplish this to avoid losing your winnings.
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. The very first slot machine as we know it is thanks to Charles Augustus Fey, who created it 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, named Cash Splash, came from Microgaming, and it had considerably high payments. Nowadays, Mega Moolah is the jackpot that owns a record payout of €17.9 million.
Playing online slots is perfectly legal in places where online gambling is allowed; otherwise, you can’t legally play slots online. Therefore, we recommend you check the legality of the online casino in your country.
Differently from machines, online slots are not tangible and therefore raise suspicion among players. However, we highlight the importance of the providers exactly because they are directly responsible for the reliability of slots.
The slot games, whether with a jackpot or not, count on RNG (Random Number Generator) software that keeps generating random results. Therefore, neither the casino nor the provider can control the slot result.
Add that to the fact that licensed casinos operate under strict regulations, some audited by third-party auditing companies. Thus we can conclude they are safe games. Also, all deposits and withdrawals related to such slot games are encrypted by SSL certificates, which keep your data hidden.
Here is a complete online slots glossary to help you learn the important slots terms:
As a game that is completely free from skill requirements, slots can be categorized based on their volatility. This allows 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 payouts will be 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. 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.
As it may be clear by now, the reels are the columns on video slots with several symbols that fall at random. Classic slots tend to have only 3 reels, but modern ones present 5, sometimes even 6. Nowadays, most online slots consider all rows of a reel for their paylines.
In its simplest form, whenever three symbols fall in sequence (usually from the first left reel) over an active payline, the user wins something.
Some slots will allow players to determine how many paylines (“lines”) they want to keep active. Remember, the fewer the lines, the less chance you have to get a winning payline.
The combinations that result in winnings must fall where a payline is traced, or nothing is added to your winnings. Slots count combinations from left to right as a standard, and usually the first symbol must be on 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, you may have seen the acronym “RTP”. Consider this when picking a game, as it’s even more important than the design and other features of the game
In short, it means Return to Player and estimates the house edge after playing for a long while – but it’s still only an approximation. For example, an RTP of 98% means the house edge is 2%, which is 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 also remember that outcomes depend on luck and how long you play.
Finally, rest assured casinos cannot control the RTP of slot games thanks to the game developer’s RNG software. Whatever is described as the RTP is the correct estimate for that title.
We should emphasize that no specific pattern increases the chance of winning a jackpot. But you can feel more in control by understanding the game’s dynamics. So, after selecting a slot game with jackpot prizes, first check the game’s pay table. There, the minimum bet to win the jackpot should be clearly outlined.
Set the bet to that amount and simply spin. The jackpot is a random feature and winning it depends on your luck. Also, the jackpot may not be available for bonus funds or during free spins. This is why it’s wise to review the game rules.
Many players who sign up to the best online casino sites for slots aim at jackpot games because of their huge prizes. For inspiration and to appease your 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 |
Tournaments are a great way to increase the possibility of being awarded something while playing slots. On top of the normal pay table and the jackpot, users get cash and prizes for ranking 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 specified games whenever possible. You’ll get ahead easier if you play 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 containing 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 |
Above you’ve seen what RTP is and how valuable that percentage is to define the payout of slot games. Below you’ll see which online slots to look for when playing on the best online casinos, so you can look forward to the highest payouts:
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 – it will only reset if the funds are gone. That is a great way to test a game and learn its tricks, besides discovering its features and bonuses.
Just remember, it is impossible to collect any winnings from free play. To win cash, 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 you can’t collect, start playing for real as soon as you find your favorite slots.
Online slots allow people to play from anywhere, as long as they have a reliable internet connection. You can access these on devices ranging from computers to smartphones. However, that is not the only advantage of online slots to the gambling world.
Some countries do not allow land-based casinos, and citizens of those regions can often rely on online slots to still enjoy their favorite pastime. Otherwise, only on an overseas trip could they ever experience the thrill of playing slots.
Also, online slots provide the best in-game features, free spins and 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 of 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 offer a series of exclusive bonuses, such as free spins.
In addition, some casino games have rather complex rules. Slots are practical and demand nothing but a single tap on the screen. If the player picks a low-volatility game, 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 you have almost limitless fun. Fortunately, our selection of the best casinos for online slots offers both quality and variety.
