RubyPlay is a modern software provider that’s been around since 2017. Their focus is entirely on slots, and they do that well. They have introduced several exclusive features. For example, RubyPlay has the Immortal Ways engine, Jackpot Pick Deluxe, and Explosion Free Games.
These features are cutting-edge; there’s a reason we currently rank them as the no. 1 free slot studio in the US sweepstakes space.
That said, we have also spotted the occasional RubyPlay slot at real-money US online casinos such as FanDuel and Wheel of Fortune.

Most popular RubyPlay slots
RubyPlay has built a reputation for producing some of the most creative online real-money slots, with a growing library of over 130 titles. Their collection is made up of several modern progressive jackpot slots, featuring unique mechanics like the Immortal Ways engine, alongside a handful of classic-style options.
From mythology to wildlife and beyond, here are five popular RubyPlay slots worth exploring.
Immortal Ways Buffalo
| Number of Reels | 6 |
| Paylines | 10,000 |
| Bonus Rounds | Immortal Array, Free Games |
| Slot Type | All Ways Pays video slot |
Immortal Ways Buffalo is a 6-reel American-inspired slot that brings 10,000 paylines and a max win of 3,221x your bet. I particularly enjoyed the Immortal Array feature, during which Gold Coins stick around for up to 3 spins. This allowed for multiple chances to land special features, jackpots—Mini, Minor, Major, or Grand—and multipliers from 2x to 7x. That’s not to mention the possibility of unlocking 8 free spins by landing 3+ scatters in the base game.
Elephant Stampede
| Number of Reels | 5 |
| Paylines | 50 |
| Bonus Rounds | Stampede Rush, Jackpot Pick, Stampede Choice |
| Slot Type | Free jackpot video slot |
Elephant Stampede takes you to the heart of an African safari via a 5×3 grid with nothing short of the highest-quality visuals and medium to high volatility. Land 3+ scatters, and you get to choose between two bonuses—free spins with extra wilds or the Stampede Rush feature. If you collect 6+ coins during the latter, you can also trigger respins to fill rows with African masks and potentially activate the Minor, Major, or Grand jackpots. The RTP of 96.91% is well above-average and, ultimately, you can win up to 1,900x your bet.
➡️ Did you know? A LottoStar player in South Africa recently hit an incredible jackpot of 28.6 million Rand (over $1.5 million) on RubyPlay’s Elephant Stampede Privé—all from a single bet.
Mad Hit Marlin Bonanza
| Number of Reels | 5 |
| Paylines | 243 |
| Bonus Rounds | Mad Hit Instant Pay, Jackpot Pick Deluxe, Free Spins, Bonus Buy Feature |
| Slot Type | Video slot with fixed jackpots |
Mad Hit Marlin Bonanza is a medium-variance fishing-themed slot with 5 reels, 3 rows, an RTP of 96.27%, and a max win of 5,567x. The game follows a fish on a treasure-hunting journey full of surprises. My favorite feature is that when the Mad Hit symbol lands with a Wild, it expands to cover the whole reel. Even better, if it’s paired with a Prize, you win instant rewards. There’s a lot of other things happening. Make sure to keep an eye on the Jackpot Pick Deluxe, where you can win one of four jackpots and even multiply your prize by up to 10x.
Go High Olympus
| Number of Reels | 5 |
| Paylines | 50 |
| Bonus Rounds | Go High, Free Games, Bonus Buy Feature |
| Slot Type | Non-progressive video slot |
Go High Olympus sets the stage for an adventure with the gods through a 5-reel, 4-row layout with 50 paylines and medium to high volatility. The Go High feature unlocks extra rows and awards 3 respins when you collect 4+ Prize symbols. Each new one that appears stays locked in place and resets your respins while giving you a shot at jackpots hidden within the prizes.
The Free Games are equally captivating if triggered (by landing 3+ Scatters). Spin the wheel to reveal your number of free spins and line multiplier, with each Prize symbol awarding an instant win and the chance to retrigger the feature. The maximum win goes up to 4,873x your wager.
Diamond Explosion 7s
| Number of Reels | 5 |
| Paylines | 50 |
| Bonus Rounds | Link It Up Explosion, Jackpot Pick Deluxe, Free Spins |
| Slot Type | Classic-style slot with a fixed jackpot |
Diamond Explosion 7s is more of a classic Vegas slot with 5 reels and 3 rows at a 96.82% RTP and an 8,000x max win. That said, it brings 50 paylines and a few quite innovative features unlike most other old-school titles. The free spins trigger by landing 3+ horseshoe symbols, and each round guarantees a reel loaded with Wilds and Diamonds. Things get even more exciting with the Link It Up Explosion feature—land 6+ Diamonds to merge them into larger shapes for bigger prizes. And don’t forget the Jackpot Pick Deluxe, where any Wild symbol could trigger a chance to win one of four jackpots, potentially multiplied.
RubyPlay software
RubyPlay has a reputation as a forward-thinking iGaming development studio. With headquarters in Valletta (Malta) and Kyiv (Ukraine), they focus on creating online slot games that push on bold designs, engaging gameplay, and themes that always deliver on fun. Here are a few general observations I had after playing their games for several hours:
Graphics
RubyPlay games are very much known for their attention to detail. Take slots like Mayan Cache and Book of Riches Deluxe: Chapter 2—they’re great examples, packed with high-quality animations. It’s really their modern, colorful symbols and cutting-edge 3D modeling that make everything look so lifelike. On top of that, the immersive backgrounds match the themes perfectly, and the advanced graphics tech makes sure the games run smoothly no matter what device you’re playing on.
Sounds
Whether it’s the Byzantine-inspired music in Go High Olympus or the more playful and laid-back tunes of Mad Hit Marlin Bonanza, I believe RubyPlay does a fantastic job of matching the soundtrack to each game’s theme and story. While it’s completely natural for audio to feel a tad repetitive during longer sessions, I love how they adjust intensity based on gameplay progression.
Playability
RubyPlay is all about making games that are fun but also really focused on the player. Their interfaces are super user-friendly and work perfectly well on both desktop and mobile. I’m talking about intuitive menus where you can easily find stake ranges and spin buttons, quick access to turbo mode or autoplay, and a paytable that’s always just a click away.
I also find their rules and features relatively easy to understand and follow, even with unique mechanics like the Immortal Ways engine or multi-feature bonuses such as Jackpot Pick Deluxe. Plus, most of the games feature medium-to-high volatility and RTPs above the industry standard of 96%. As for stakes, they’re great for casual players, often starting at $0.10. However, if you’re a high roller, you might find the upper limits slightly restrictive.
Safety & Trust
RubyPlay holds licenses from Curaçao, Malta, and Romania, so their games meet international regulatory standards. As for its portfolio, it caters to a fair range of markets, including the US, LATAM, Europe, and Asia. Games are available in multiple languages for broad accessibility.
On top of that, they’ve earned serious recognition for their innovation and quality. For example, in 2023, they won three awards, including Best Online Casino Game for Immortal Ways Mr. First.
Types of RubyPlay games
It’s impressive when providers like NetEnt branch out into all kinds of online casino games. But RubyPlay is different. They put all their efforts into slots to deliver unique and exclusive concepts that carve out a distinct niche in the market.
Slots
RubyPlay takes pride in its unique game series, including Diamond Explosion, Giga Match, Go High, Immortal Ways, J Mania, Mad Hit, Rush Fever, and Ten Ton Ways. These achievements have been recognized with awards, like FTN Game of the Year for Mad Hit Olympic First in 2024 and BFTH Favourite Casino Company at the 2023 Arena Awards.
You’ll find RubyPlay’s best online slots at leading social and sweepstakes casinos like Wow Vegas and McLuck. These range from classic 5-reel games to more feature-packed titles with cascading reels, free games, and more.
Other Game Types
RubyPlay focuses exclusively on slot games, so you won’t find RNG table games, live dealer games, virtual sports, or specialty options like crash games, keno, plinko, scratch cards, or online bingo. If those are what you’re after, here are a few studios to check out:
- Shuffle Master – Best known for its table games like ‘Let It Ride,’ along with blackjack, craps, baccarat, and poker-style options. Popular titles include Blackjack Switch, Mississippi Stud, and Ultimate Texas Hold’em.
- Light & Wonder – Perfect for social casino games with fish games, bingo, and solitaire offered through their SciPlay subsidiary, alongside other classic-inspired slots.
- IGT – Try out IGT’s video poker games like ‘Game King,’ which combines nine poker variants in one, as well as Triple Play Draw and the Ultimate X series.

RubyPlay offers everything from old-school fruit-themed slots to feature-rich multi-way online slots. All their titles are fully optimized for any screen size, complete with high-quality 3D animations. However, what truly sets them apart from competitors, in my opinion, is their take on the following bonus features:
Immortal Ways Engine
Jackpot Pick Deluxe
RubyPlay’s Jackpot Pick Deluxe is activated in games like Zeus Rush Fever and Diamond Explosion Sweet Love by landing specific symbols, often Wilds. This gives you a shot at one of four jackpots—Mini, Minor, Major, or Grand—and the chance to increase your winnings even further with multipliers of up to 10x.
Free Spins
RubyPlay’s free spins rounds, such as the ones available in Elephant Stampede and Mad Hit Marlin Bonanza, activate when you land 3 or more Scatter symbols. They work just like any other free spins but often come with perks, such as guaranteed Wild reels, sticky symbols, or multipliers, depending on the game.
