In the iGaming market, where over 250,000 games are tracked monthly and hundreds of casinos vie for player attention, only a fraction truly contributes to ongoing revenue. A fact repeatedly confirmed by operators is that the majority of the turnover is driven by a handful of top games, with thousands of new titles competing for limited attention in the same lobby. Richard Ganster, Director of Game Strategy and Portfolio Management at Greentube, recently made a straightforward assessment in an interview: the top games of 2026 will rely not on explosive launch week performance, but on the stickiness that keeps players coming back. Greentube, as the digital entertainment branch of the Austrian gambling giant NOVOMATIC, holds long-standing flagship products such as "Book of Ra Deluxe" and "Lucky Lady's Charm Deluxe" that span both online and offline platforms, while directly observing player behavior through B2C brands like Admiral Casino and StarVegas. Ganster's perspective, perfectly positioned between suppliers and operators, is summarized in one sentence: sustained engagement is the winning formula, and short-term revenue spikes don't tell the whole story.
From acquisition to retention, the measuring stick has changed
While the industry used to focus on RTP, Ganster believes that looking solely at return-to-player rates is no longer sufficient to judge a game's commercial viability. Developers are now more concerned with metrics like spins per session, feature trigger rates, and bonus buy usage rates, which directly reflect whether mechanics are truly driving continuous player engagement. Operators, on the other hand, monitor metrics such as GGR per round, frequency between rounds, and 7-day and 30-day return rates, using retention data to profile the lifecycle of a game. Ganster succinctly states: ARPU only makes sense when paired with round-level retention data; a game that keeps players coming back is always more valuable commercially than one that peaks in the first week and then quickly cools off. Greentube's approach is to incorporate these considerations into the design phase, ensuring that the game loop supports sustained interest rather than relying on one-time visual stimuli to trick clicks.
Mobile-first is not just a slogan, it's about shrinking patience, not screens
Ganster is almost harsh in his emphasis on mobile design. He points out that cramming a five-reel layout from a 27-inch monitor into a 6-inch phone screen, even with proportional scaling, is doomed to fail. True mobile-first design must start from the distribution of thumb hot zones, placing key controls in the most accessible area at the bottom of the screen, while also accommodating vertical holding habits. The shorter session lengths on mobile also force an adjustment in game pacing—reward mechanisms must reach players faster, and feedback loops must be tighter. Players' tolerance for loading delays and high power consumption is particularly fragile in emerging markets, while overly cluttered interfaces are equally fatal. Greentube's design philosophy rests on three pillars: simplicity, clarity, and stable performance, ensuring that games run smoothly across different devices and network conditions.
Lobby placement determines fate, discoverability is the invisible battlefield
The economic return of a game varies greatly depending on whether it appears on the first screen or is buried on the third page of an operator's lobby. Ganster bluntly states that lobby display positions are the hardest currency. This makes the relationship between suppliers and operators, as well as the ability to demonstrate expected performance before new games are launched, more important than ever. Product portfolio strategy is also key—new titles must complement existing content, not duplicate it. With its vast game library and years of B2B experience, Greentube can precisely identify gaps in an operator's content matrix and position itself accordingly. Innovative features like the Diamond Link jackpot system and Win Ways mechanics allow games to tear through homogenized competition.
Viewing players should not be limited to age, but consider the context in which they play
Ganster opposes labeling players by birth year. Younger players may prefer high volatility and short sessions, while older groups are more accustomed to familiar formats and longer game durations, but these patterns shift with time, device, and context. The most useful analytical dimension is the session context—a player's behavior during commute times and weekend evenings on the couch can be drastically different. Greentube's dual perspective across B2B and B2C allows it to read the behavioral patterns behind scene shifts from the data and feed this understanding back into game design.
PASA official website continues to track global online casino game product strategies and player retention dynamics, noting that Greentube's retention-centric design philosophy is becoming a common language among top suppliers. As the market shifts from incremental competition to stock competition, whether a game can survive the first month on a player's phone is far more strategically valuable than first-week download and turnover rankings. Ganster's closing statement is emphatic: In a saturated market, retention is everything. If a game can't retain players, even the biggest launch momentum is meaningless.
