Greentube has been around for many, many years, so it’s had plenty of time to build up a great selection of games and an equally good reputation among players.
There's more than enough variety here, with more than 400 slots, table games, video poker, bingo, and even social casino games. Greentube Alderney Ltd is part of the Novomatic Group, which just speaks to the quality of the games and overall experience you can look forward to.
In my full guide, I’ll give you the inside scoop on which slots you should try, tell you a little more about the Greentube Novomatic partnership, and let you know how to bag some exciting casino bonuses to use at top Greentube casino sites.
As a leader in online gambling, it’s no surprise that Greentube games are found at hundreds of trustworthy online casinos worldwide. All of these sites carry valid licenses, so you can be assured that you’ll have a safe experience. But when you’re choosing a casino site, there are a whole lot of factors you need to consider before you sign up.
The sites that I’ve listed on this page all offer a great selection of Greentube games, as well as top real money slots from other providers and even live casino tables. These online casinos also have exciting bonuses like deposit match offers and free spins, plus they support convenient and trustworthy payment methods like bank cards, e-wallets, and crypto. You can even play Greentube slots free at some of my recommended casino sites.
So if you’re ready to find out everything you need to know about the best Greentube casinos in the world, keep reading!
Greentube started life way back in 1998 before rebranding as Greentube Internet Entertainment Solutions AG in 2000. Finally, in 2010, they joined up with the well-known game provider Novomatic as the Digital Gaming and Entertainment division.
Novomatic has been around for 40 years, having been founded by Prof. Johann F. Graf in Austria in 1980. Over the years, Novomatic has definitely become established as one of the main players in the gaming world, not just in Europe but globally. So, Novomatic's acquisition of Greentube just speaks to the excellent quality and reputation of both brands.
There are a lot of exciting game mechanisms to look forward to when you play Greentube slots. For example, some games (like the Diamond Link series) share jackpot prize pools and give you more chances to win through special features, while the Win Ways mechanic removes winning symbols from the grid to give you a chance to make more winning combinations.
There are around 400 different Greentube slot games, so you won’t want to spend lots of time trawling through them to find the one that works best for you. I’ve tested out all the top games and compiled a list of my five favorites, which you can try now at top Greentube casino sites.
Book of Ra Deluxe is one of a series of similar games, all of which are set in Egypt. Every time you spin, up to seven symbols can land on each of the reels, plus there’s an extra reel at the top of the game grid, creating up to 117,649 ways to win. Winning symbols become part of a reaction, allowing more symbols to land and giving you even more chances to win. Look out for scatter symbols, which can award ten free games, and wild ones, which substitute for other symbols on the grid.
Set against an elegant pink backdrop, Lucky Lady’s Charm Deluxe features a lucky fairy who will help you conjure up wins! Symbols to look out for include ladybirds, clovers, and gold coins, and you’ll win by lining up enough of the same symbols on one of the ten paylines. The lucky lady wild symbol doubles your wins, and there’s also a free spins round that awards you with 15 free games, which come with a multiplier of either 3x or 6x on all of your wins.
If you love the look and feel of classic slots, then this top Greentube online casino game is perfect for you. Sizzling Hot Deluxe features symbols like cherries, grapes, and lemons. The slot concentrates on simple gameplay, so there aren’t a whole lot of special features, unlike on some other video slots. With medium volatility and an RTP of a respectable 95.66%, Sizzling Hot Deluxe is a great option for all casino fans.
Set underwater, Dolphin’s Pearl Deluxe comes with ten fixed paylines, giving you lots of chances to align symbols like clams, seahorses, and shoals of fish. The dolphin symbol acts as the wild, substituting for other standard symbols and multiplying your wins by 2x. Landing three or more of the pearl scatter symbols will open up the free spins round, where you’ll get 15 free games, which can be re-triggered to give you even more chances to win.
Join the Lord of the Ocean, Poseidon, on a quest for wins across five reels and ten fixed paylines. Look out for the special gate symbols, which trigger the free spins round, where an expanding symbol will be revealed, covering the whole reel and giving you extra chances to win. The game graphics are excellent, and some of the high-paying symbols to look out for include underwater creatures, beautiful goddesses, and, of course, Poseidon himself.
Some games (like the Diamond Link series) share jackpot prize pools and give you more chances to win through special features, while the Win Ways mechanic removes winning symbols from the grid to give you a chance to make more winning combinations.
While Greentube might not launch new online slots quite as often as some other providers, you’ll usually be treated to a release roughly once a month. I looked at some of the best new games for 2024, which are available now at the best Greentube casinos.
This futuristic game is set in a neon-drenched city and features unique characters like Kray-Z the Reaper and Y-Pout the Assassin. The game is played on a grid of six reels and five rows, and it comes with tons of special features. Look out for multiplier wilds that can increase your winnings by up to 5x; plus, there’s a free spins round that includes different modifiers that can add to or multiply your wins.
This fun slot game is based on the classic tale of the little mermaid and her prince. There are 40 ways to win, and the game comes with five different story chapters, which you can progress through on your way to the very special Ocean Feature. As you progress, you’ll have the chance to win bigger and better cash amounts. The game also has Pearl Heart symbols, which come with multipliers, and bonus rounds where you’ll get more Pearl Hearts on the reels and, therefore, more chances to win.
I love this game's mystical look and feel and the magical graphics. Land four or more of the special scatter symbols anywhere on the reels, and you’ll enter the Lock & Spin Wincreasing bonus round, with respins and mystery multipliers awarded to wins after every spin. There’s even an additional row of symbols to give you more opportunities to create winning combinations.
Greentube doesn’t necessarily make progressive jackpot slots, but it has been known to introduce them to certain slots for a limited time only. For example, Greentube previously ran an offer where a progressive jackpot was available across four slots (Book of Ra Mystic Fortunes, Goddess Rising, Pyramid Fortunes, and Vampire Fortunes), and players could win one of four jackpot prizes by lining up the right combination of symbols during the special round.
Top Greentube online casinos offer lots of different bonuses both for new and returning players.
When you sign up at a new online casino, the most common type of offer you’re likely to see is a deposit match, where you’ll usually get 100% of your deposit added to your balance as extra money to use on slots. You might even get some free spins to use on top games.
As a regular, it’s likely that you’ll get frequent offers, and some gambling sites might have different ones every day or every week. From free spins to reload bonuses, slots tournaments, and giveaways, there’s plenty to look forward to.
Before you claim online casino offers, it’s important to read the terms and conditions in full. There are a few different common rules you’ll see applied to casino bonuses, such as wagering requirements and maximum win limits. If you’re planning on playing Greentube games specifically, make sure you check that the offer you’re claiming can be used on them. If you’re using free spins, you might have to play them on a game from another provider and then use your winnings to play Greentube slots.
One of the first things I noticed about Greentube games is that they’re totally optimized for mobile play. Greentube understands that a whole lot of players all over the world prefer to game on their mobile phones rather than on desktop, so it’s super important that games function perfectly on smaller screens - everything from visuals to game speed to special features needs to be flawless on mobile. Luckily, Greentube has done a good job of achieving this.
The best mobile Greentube casino sites give you two different ways to play - via a mobile casino app and via a mobile website on your usual browser. The differences between the two are usually small, so you can use whichever suits your preferences. Greentube games are built using HTML5 technology, which means that they’re supported by all of the common mobile browsers, like Chrome and Safari.
The provider has also won numerous awards over the years, which I'll cover below.
‘Industry Pride of the Year’ at the Women in Gaming (WiG) Diversity Awards 2021
Greentube’s technology and processes are modern and robust, ensuring absolute peace of mind when you play the games.
Greentube slot games make use of Random Number Generator technology, so the outcomes are totally fair, and you could stand a chance to win real cash. Greentube slots RTP is defined for each game, and this gives you an indication of how likely you are to win over a long period of time.
Greentube holds a Global Gambling Guidance Group (G4) certification, underscoring their commitment to responsible gambling and player protection. To receive the certification, Greentube was evaluated against a set of 100 criteria, so you can rest absolutely assured that they have your best interests at heart.
Top Greentube online slot sites also have their own measures when it comes to licensing, security, and responsible gambling. All of the sites that I recommend on this page hold valid licenses, and they use extra measures like encryption and strong data protection policies to keep you safe.
Even if you’re as impressed with Greentube as I am, it is still helpful to see how it compares to other software providers. I’ve put together a quick comparison against some of the biggest providers in the world.
When compared with Pragmatic Play, I have to say that Greentube comes second. While their range of games is impressive, Pragmatic’s visuals and special features (like the Drops & Wins promo) really make the provider stand out from any competition.
I always like to compare other providers against Games Global because there’s one thing that most providers can’t touch—the progressive jackpots. Greentube does have progressive jackpots, and while they can reach decent amounts, they’re not always available, and they have nothing on the seven-figure jackpots of Games Global’s Mega Moolah slots.
Hacksaw Gaming and Greentube are pretty different, but that doesn’t necessarily mean one is better. While Greentube concentrates on stripped-back and user-friendly games that function across platforms, Hacksaw is specifically known for being innovative and creating mobile-first gaming solutions, which don’t work quite as well on desktop.
If you’re looking for the best places to play Greentube online slots, you’re definitely in the right place. As you might know, our team at Casinos.com is made up of lots of professional casino players who know exactly what to look for in great online casino sites.
Before we recommend any online casino site, we first look at whether it is licensed and secure. We only list sites that have a valid license to accept players from your region and use tools like encryption technology, firewalls, and secure payment methods to keep you safe.
Another major consideration is the range of bonuses and promotions. We look for welcome offers for brand-new players (like exciting deposit match bonuses or free spins), as well as regular reloads, cashback offers, or slot tournaments for players who keep coming back. Top Greentube casino sites even have VIP programs for top-tier players.
It’s great to see an extensive selection of Greentube slots; there’s a whole lot more that should go into a games lobby. From slots from top providers like NetEnt and Pragmatic Play to a full suite of live casino games, we look for sites that have a wide variety of options.
Finally, we take an in-depth look at the overall casino experience. Does the site have 24/7 customer support? Is it mobile-friendly? Can you navigate and find your favorite games in a hassle free way? We make sure to answer all of these questions before we suggest a gambling site to you.
