Best Greentube Slots to Try

The Greentube slots list offers hundreds of masterpieces with legendary statuses, so picking just a bunch of them might be heavy. I rank the picks below according to my own preferences and knowledge about the history of the games. Make sure to test them for free before staking real money. Ideally, you will try at least several more before making your final decision!

Book of Ra Deluxe 10

Book of Ra Deluxe 10 slot

Book of Ra Deluxe 10 is one of the most popular sequels of the series. It was released shortly after the original in 2019 and offers low to medium volatility and a unique layout. The RTP rate is weaker than expected - 95.02% and the max win is capped at 1,143x the bet. The action takes place on two reel sets that spin together - 5x4 and 5x12, with 100 paylines each.

Book of Ra Deluxe 10 is packed with several features as well, and perhaps the stacked wilds is the most exciting one. Whenever that occurs on reel 1, the stack will copy itself on reel 2. The Free Spins bonus comes with retriggers and a special expanding symbol. However, it will copy itself on the respective reel on the 5x12 set and will act as a special stacked symbol.

Diamond Tales: The Ugly Duckling

Diamond Tales: The Ugly Duckling slot

Diamond Tales: The Ugly Duckling is a highly volatile slot released in 2022 with an RTP rate reaching 96.01%. It is one of the Greentube slots with the highest max wins - 50,000x the bet. Moreover, the series received very high rankings in 2022, and all titles from it enjoy solid popularity. The game is played with 40 lines on a 5x4 grid.

Diamond Tales: The Ugly Duckling stands out with premium-class audio and visual effects and an exciting Hit Frequency rate of 32%. There are 5 main gameplay features, including bonus spins, bonus symbols, and the series special Diamond Tales Feature. In addition, Greentube has added a Buy Bonus functionality.

Dolphin's Pearl Deluxe

Dolphin's Pearl Deluxe slot

Dolphin's Pearl Deluxe is one of the first very popular slots in Greentube's online slot repertoire. It was launched in 2009 with improved graphics compared to the original slot from 2008. The game is available with multiple payout rates, reaching 96.25% and even 97%, but the most widespread version has a coefficient of 95.13%.

Dolphin's Pearl Deluxe is a highly volatile slot with an attractive theme and a max win of 4,638x the wager. The grid consists of 5 reels and 3 rows and has 10 configurable paylines. Dolphins land as high-valued wilds that substitute for all regular symbols. Scatters also pay well but also trigger a Free Spins bonus with an x3 win multiplier.

Sizzling Hot Cash Connection

Sizzling Hot Cash Connection slot

Sizzling Hot Cash Connection is another high-variance Greentube slot based on a legendary slot. The Cash Connection addition enhances the classic gameplay with 2 progressive jackpots. A couple of fixed jackpots are also in play. The slot has an RTP rate of 95% and a layout of 5x3 with 5 fixed paylines.

Sizzling Hot Cash Connection is a fruity slot with large regular payouts and skaters that pay up to 2,500x the bet. However, the core feature here is a Lock & Spin feature with the participation of Cash and Jackpot symbols. The minigame is a classic variant of the Hold & Win bonus with 3 respins that reset when new paying symbols appear.

Diamond Link: Cops' n' Robbers

Diamond Link: Cops' n' Robbers slot

Diamond Link: Cops ‘n’ Robbers was released in 2023 to unite a couple of amazing series. The Diamond Link progressive jackpots reduce the RTP down to 93.70%, but high rollers will appreciate the opportunity. It is a medium volatile slot with awesome graphics, animation effects, and audio that pays up to 1,000x the bet in its regular form.

Diamond Link: Cops' n' Robbers has much more than progressive jackpots, and in fact, it is considered a feature-packed game. The 5x4 board is packed with 20 paylines and an amazing Board Game with exponentially increasing multipliers. The Diamond Field, ID Parade, and linked jackpots make the gameplay truly mesmerizing.

Ultra Hot Deluxe

Ultra Hot Deluxe slot

Ultra Hot Deluxe remains one of Greentube’s most enduring classics, still spinning in countless casinos years after its debut. It uses a 3x3 layout with 5 fixed lines and medium volatility, delivering the unmistakable feel of traditional fruit machines. The RTP is set at 95.17%, keeping the numbers in the comfort zone for steady play.

Symbols include the timeless lineup of fruits, bars, stars, and fiery sevens that blaze across the screen when a full grid lands. Full-screen combinations double the payout, turning a simple mechanic into a quick, satisfying loop. Ultra Hot Deluxe keeps proving that sometimes, all a slot needs is clean design and fast results.

Greentube Slots With The Highest RTP

Like many other slot providers, Greentube's work can be divided into two periods. In the early years, the company has been producing high-RTP titles with low to medium volatility. Then, the trend went upside down, and players started to seek highly volatile slots. Here is an overview of the highest Greentube slots RTP rates:

Gangster Paradise - Highest RTP Slot by Greentube

Gangster Paradise was launched in 2019, and it's the highest-RTP online slot ever built by Greentube. Although it is available with several different rates that even go under 90%, the most generous version reaches an impressive 97.26%. The 5x3 matrix offers 25 paylines, and the max win is 12,500x bet per line or 500x the total bet.

Gangster Paradise does not boast too many features, and the base game has the potential to pay very well. Scatters will trigger the Free Spins bonus and have the power to add extra rounds during the minigame. During the bonus, a reel completely covered by the same symbol acts as a wild reel, significantly increasing the payout capacity of the game.

Greentube RTP Rates

Most of the free Greentube slots that my colleagues and I tested have adjustable RTP rates that can exceed 97% on certain occasions. On the flip side, some of the titles may drop down to 88% or even lower. These variants are crafted for markets where regulators forbid slots with RTPs above certain limits. It will be wise to avoid games from the category with low coefficients.

Greentube has a couple of dozen or even more games that fit other genres. Royal Crown Blackjack is the one with the highest RTP rate - 99.60%, while Diamond Cash Lotto has the lowest - 93.70%. Other Greentube games that are worth checking out are Book of Ra Multi Card Bingo Deluxe (93.89%), Lucky Lady's Roulette (97.30%), and Grand Blackjack.

Special Features of Greentube Slots

Greentube has classic slots with few or no features at all but also action-packed games with plenty of bonuses. It is all up to you which games you prefer, but in this section of my review, I'll present the most common features. Feel welcome to check the highlighted Greentube slots, follow the links, and give them free trials.

Free Spins

Many of the best Greentube slots have Free Spins features, along with base game modifiers. My research showed that nearly 340 online slots by the provider are packed with this bonus. Keep in mind that the Free Spins minigames never come with zero extras, and you can count on wild modifiers, multipliers, jackpots, and many others.

Progressive Jackpots

Greentube is one of those slot providers that know how to develop a progressive jackpot network. Diamond Mystery, Diamond Cash, and Diamond Link are only some of the series that have this type of reward. Keep in mind that the rules may differ, and there could be a minimum bet threshold. These slots often come with lower RTP rates as well!

Win Ways

Win Ways is a sensational mechanic you can test in nearly a dozen Greentube free demo slots at SlotCatalog. It allows players to use a huge number of ways to win to scoop even more payouts. Symbols must be on adjacent reels from the leftmost side of the board to the right. Several different variations of the mechanic are available.

Branded Slots

Branded Slots

Fans of branded slots will find a few among the Greentube casino games. There are not too many, and they are mostly from the 2012 - 2015 period. That will include a couple of titles inspired by David Hasselhoff - Hoffmeister and Hoffmania, the Royal Dynasty, and a slot based on the popular Rex TV series. Several newer branded slots are also available, like the 2020 From Dusk Till Dawn 10 based on the Tarantino movie starring George Clooney.
