Studio Heritage & Novomatic Foundation
Greentube began in 1998 building browser-based casino titles, then shifted to full HTML5 as smartphones became the norm. In 2010, Novomatic acquired Greentube, enabling faithful online adaptations of cabinet classics (e.g., Book of Ra, Lucky Lady’s Charm) and a steady flow of new series.
Milestones include:
- Early 2000s: Flash/Java browser games establish the studio’s reputation for smooth maths and clean UI.
- 2010–2015: Integration with Novomatic brings iconic land-based titles online.
- 2016–2019: Full move to HTML5; portfolio becomes mobile-first.
- 2020s: Wider rollouts across regulated EU markets, plus fresh franchises like Starlight Jackpots and Gang Wars.
The result is a catalogue that blends heritage themes with updated volatility models and modern bonus frameworks—without sacrificing clarity.
Mechanics That Shape Greentube Games
Greentube’s design leans on readable reels and structured bonuses. Below are core mechanics, each with a quick view of how it plays in-game.
Diamond Link™ (Hold & Spin + Jackpots)
How it plays: Collect diamond/coin symbols to trigger a Hold & Spin round. Each symbol locks and grants respins; filling the grid or landing special icons can step you through Mini, Minor, Major, and Grand jackpot tiers.
Example: Diamond Link™ Mighty Elephant — Hold & Spin rounds layer fixed prizes with jackpot shots for notable gameplay highlights..
⚠️Important Note: Jackpots and maximum win figures are rare events. Outcomes are always random and cannot be influenced by strategy.
Win Ways™ (Flexible Ways to Win)
How it plays: Instead of fixed paylines, wins form via adjacent symbol chains, often scaling ways as reels expand or stack. This increases route variety while keeping outcomes transparent.
Example: Book of Ra Deluxe 10: Win Ways — dual-reel format and ways expansion create more connection paths during features.
Expanding Symbols (Classic “Book” Style Free Spins)
How it plays: Free spins select a special symbol that expands to cover its reel when a win is possible, paying across lines even when symbols aren’t adjacent in the usual way.
Example: Book of Ra Deluxe — a single expanding symbol can swing bonus rounds without complex modifiers.
Hold & Spin (Cash Collection Variants)
How it plays: Landing a set number of special icons triggers respins where only prize symbols appear. Each new symbol resets the spin counter; totals are added at the end.
Example: Starlight Jackpots – Odds of the Gods 2 — combines cash collection with tiered prizes for simple, engaging rounds.
Multi-Level Bonus Rounds (Feature Ladders)
How it plays: A base bonus can progress into higher tiers with stronger modifiers (multipliers, symbol upgrades, mystery stacks).
Example: Gang Wars — advance through turf levels to unlock enhanced prize potentials while keeping the UI readable.
