Greentube Company Overview – Leading Provider of Online Slots and Gaming Solutions
Greentube isn’t a household name but it’s connected to one of the most recognized casino games providers, Novomatic. The studio was created as its interactive division, and games produced by both the parent company and its subsidiary share a lot of similarities.
There are all sorts of online games the studio creates including table games, video poker, video bingo, and social casino titles. But the key product has always been video slots. When playing any of its titles, you won’t worry about safety and security as this legitimate and reputable provider certifies its software and has a great reputation.
Even though Greentube is a division of a bigger company, it also has its subsidiaries. There are many Greentube offices across the world, plus a range of other brands such as Ski Challenge, Funstage, Platogo, BlueBat Games, and AbZorba Games. They deliver a wide spectrum of products and services.
Greentube Slots
Greentube has produced new versions of iconic hits that are there for over a decade. For instance, Book of Ra, and Dolphin’s Pearl are now available in multiple new variations that feature modern engines such as Cash Connection, Win Ways, etc. These iconic slot machines were developed when there were no advanced features available today, and by introducing new features, Greentube makes sure some of the most beloved brands remain relevant today.
Although the studio has inherited many of the ideas and themes from its parent company, it has original slot themes created independently. There’s on average one new title launched a month, which is an industry-standard volume and is just the right output to ensure great quality and remain visible in the casino lobbies.
Common Slot Features
Greentube has an extensive arsenal of tools it uses to create thrilling video slots: wild, sticky, colossal symbols, multipliers, and a host of other great stuff. In addition to popular solutions that have been there for many years, it has developed a range of exclusive features and boosters that are often used in its games. Below we discuss some of them.
- Win Ways mechanic won’t disappoint you as it allows players to collect multiple wins within the same round. Winning symbols are removed from the screen allowing other symbols to fill in the gaps and potentially form new combinations. Some of the games in this series have two sets of reels, which is another exciting thing.
- Diamond Link is officially Greentube’s top-performing game series. This doesn’t come as a surprise because games offer some exciting packs of features with the greatest of them being two progressive jackpots. 1% of every wager contributes to the jackpot accumulation. There’s one rule that should be pointed out – only max stakes are eligible for the total amount accumulated in the pot. Whereas smaller bets win a share of the accumulated amount relative to the stake. The series includes exciting Greentube demo slots that you can try for free on this page.
- Cash Connection is another jackpot series. This time, the contribution is a bit smaller, 0.95% of every bet is added to the jackpot amount. There are four jackpots in total, two of them are fixed and two are progressive. Major and Grand jackpots are seeded at €2,500 and €15,000, respectively. In Diamond Link slots, the initial values are 200x, and 1,000x bet.
- Gamble feature is common in Greentube video slots. It’s a simple game during which a player is asked to choose a red or black card to double the win. It’s possible to gamble any win up to 5 times, but you should check the Help file to see some restrictions that are in place. For instance, when players land big wins, jackpot wins and during autoplay, the feature can’t be activated.
Return to Player
Greentube slots RTP is typically somewhere around 95-95.5%, which isn’t the highest but acceptable range. If you want to know exactly how much certain Greentube slots return on average, simply load games and go to the Help file. There you’ll find everything about that title, including RTP and jackpot contributions if any.
