Electronic gaming machines have become some of the most engineered consumer systems in entertainment. Modern slot machines are no longer just spinning reels and flashing lights, they increasingly operate as highly structured software platforms designed to manage probability, pacing, visual feedback, and long-term player engagement in real time.
That shift is central to Light & Wonder’s business. The company generates most of its revenue from land-based gaming cabinets while steadily expanding premium leased installations, where casinos pay based on machine participation rather than outright purchases. The model creates more recurring revenue and turns successful game mechanics into long-term platform assets rather than one-time hardware sales.
After divesting its lottery and sports betting units, Light & Wonder now focuses on three segments: land-based gaming, iGaming, and SciPlay.
The company extends many of its casino titles into digital formats through its iGaming division and SciPlay businesses, creating a cross-platform ecosystem where game concepts, mechanics, and player engagement systems can move between physical casinos and mobile devices.
Underneath all of this is a surprisingly deep patent portfolio.
Light & Wonder: Patenting Activity
The chart illustrates a clear evolution in Light & Wonder’s patent activity, beginning with a period characterized by steady growth and a predominance of granted patents.
The increased number of filings starting in 2022 coincided with Scientific Games’ rebranding as Light & Wonder, following the divestiture of its lottery and sports betting businesses to sharpen focus on gaming, iGaming, and digital content development.
The company subsequently reported strong double-digit revenue growth, record SciPlay performance, and continued investment in its R&D engine, particularly across digital gaming platforms, premium gaming hardware, and cross-platform content ecosystems.
Light & Wonder: Top Technology Areas
Light & Wonder’s patent activity is highly concentrated in gaming-specific technologies, with the largest share attributed to coin-fed or similar gaming apparatus (G07F). This dominant category underscores the company’s core focus on land-based gaming hardware and machine innovation.

Additional exposure to image and video recognition (G06V) and graphical data processing (G06K) further suggests a growing role for visual systems and user interface technologies within gaming environments.
Other categories, while representing relatively smaller portions of activity, demonstrate a diversified and supporting innovation base. These include pictorial communication (H04N), general image data processing (G06T), and time or attendance registers (G07C), which may relate to backend systems, monitoring, and operational infrastructure. Collectively, the distribution indicates that while Light & Wonder remains anchored in its core gaming technologies, it is progressively broadening its capabilities into digital, data-driven, and user-experience-enhancing domains.
Advancing engagement through next-generation gaming mechanics
Electronic gaming systems are undergoing a structural shift as developers move beyond static reel formats toward more dynamic, state-driven architectures. The following patents highlight how leading innovations are addressing core technical constraints, balancing randomness with controlled payouts, increasing gameplay depth without overloading system resources, and enhancing player engagement through interactive features. From multi-cycle reward frameworks to adaptive symbol arrays and persistence-based mechanics, these solutions demonstrate how modern game design is evolving into a more modular, scalable, and immersive ecosystem.
Multi-cycle award sequences in gaming systems
The problem
Modern electronic gaming machines rely on complex combinations of randomness, visual feedback, and reward structures to sustain player engagement. However, traditional game designs often struggle to balance two competing technical requirements: delivering sufficiently random and volatile outcomes to create excitement, while maintaining predictable long-term payout behavior for operators.
At the same time, increasingly sophisticated bonus features, such as multi-stage rewards, animations, and layered mechanics, place heavier demands on processing speed and memory efficiency. These complexities can slow down gameplay, reduce responsiveness, and ultimately detract from the user experience. Additionally, conventional single-cycle reward mechanics may lack depth, limiting player engagement and reducing the perceived variability of outcomes across repeated plays.
How the patent solves it
U.S. Patent No. 12,340,660 describes a gaming system that introduces multi-cycle award sequences triggered by specific symbol combinations.
The system uses game-logic circuitry and a presentation assembly to generate outcomes where the appearance of at least one trigger symbol and one award symbol initiates a structured sequence of reward cycles. Each trigger symbol corresponds to a separate cycle, effectively layering multiple reward events within a single game instance.
Within each cycle:
- The system selects one or more award options for each award symbol
- Award indicia (displayed values) are dynamically updated based on those selections
- The updated values are aggregated to determine the total reward for that cycle
- If additional cycles remain, the system resets or removes prior indicia before continuing
This cyclical process creates a progressive, iterative reward mechanism, enhancing both variability and perceived value.
From a systems perspective, the design improves processing efficiency by structuring reward calculations and visual updates in discrete, repeatable cycles. It also enables more advanced animation sequences tied directly to game logic, rather than requiring separate computational overhead for each feature.
Why it matters
This approach meaningfully advances gaming system design by introducing a scalable framework for multi-layered reward mechanics. Instead of a single resolution point, players experience a sequence of evolving outcomes, which increases engagement and extends play duration without requiring fundamentally new hardware. Operationally, the structured cycle logic helps optimize processor usage and memory handling, supporting smoother gameplay even with complex visual and bonus features.
For operators, the system maintains control over payout structures while enhancing the perceived randomness and excitement that drive player participation. For players, it delivers a more dynamic and immersive experience, where each trigger event unfolds into multiple stages of potential rewards rather than a single outcome.
The patent, titled “Gaming systems and methods using multi-cycle award sequences,” was filed on October 6, 2022, and granted on June 24, 2025. The listed inventors are Yanis Tsombanidis, Ted Hase, Zachary Schmid, Joshua Sieverding, and Hong Wei.
Symbol array expansion in gaming machines
The problem
Electronic gaming machines must continuously evolve to enhance gameplay experience while preserving controlled payout mechanics. Traditional slot-style systems rely on fixed reel configurations and static symbol grids, which limit gameplay variability and reduce the perceived dynamism of outcomes over time.
This static structure creates two core limitations. First, it constrains the number of possible winning combinations, capping excitement and replay value. Second, it limits how game designers can introduce new visual or mechanical features without significantly increasing system complexity.
At the same time, developers must balance these enhancements with performance constraints. Adding new gameplay layers, such as expanded reels or bonus features, can increase processing overhead and disrupt smooth gameplay if not efficiently implemented.
How the patent solves it
U.S. Patent No. 12,266,240 introduces a gaming system that dynamically alters the symbol array configuration during gameplay through expansion mechanics.
The system uses an electronic display device to present a grid of symbol positions arranged in rows and columns, populated by spinning symbol-bearing reels. Under normal conditions, payouts are awarded based on winning combinations across predefined horizontal and vertical paths.
In response to a triggering event, the system expands the array by adding additional symbol positions to one or more rows. This effectively increases the size of the playable grid in real time. The reels are then re-spun, populating the expanded array with new symbols and enabling additional payout evaluations. This approach integrates array expansion directly into the core game loop, allowing enhanced gameplay without requiring separate bonus modes or excessive computational overhead.
Why it matters
The ability to dynamically expand the symbol array introduces a scalable method for increasing gameplay variability and engagement. By transforming a fixed grid into a flexible, event-driven system, the design enhances both the perceived randomness and the number of potential winning combinations.
From a technical standpoint, the system achieves this without fundamentally altering the underlying architecture, preserving processing efficiency while enabling richer animations and feature sets. For operators, this innovation supports higher player retention by delivering more interactive and visually engaging gameplay. For players, it creates a more immersive experience where triggering events lead to tangible changes in the game environment, rather than simply awarding static bonuses.
The patent, titled “Gaming machine and method with symbol array alteration,” was filed on September 6, 2023, and granted on April 1, 2025. The listed inventors are Mats Andersson, Oliver Andrews, Adam Fox, and Lucas Parkinson.
Symbol persistence features in gaming machines
The problem
Modern gaming machines aim to enhance engagement by introducing layered mechanics and evolving game states. However, traditional reel-based systems typically reset completely after each spin, limiting continuity between successive outcomes and reducing the sense of progression within a single session.
This lack of persistence constrains gameplay depth and diminishes player engagement, as each spin is treated as an isolated event rather than part of a developing sequence.
From a technical standpoint, introducing persistence is non-trivial. Systems must track symbol states across spins, manage interactions between multiple symbol positions, and ensure that these mechanics integrate seamlessly with existing payout logic, all while maintaining performance efficiency and visual clarity.
How the patent solves it
U.S. Patent No. 12,002,329 introduces a gaming system that incorporates a symbol persistence mechanism through tagged positions within the symbol array. The system uses game-logic circuitry and an electronic display to manage symbol behavior across multiple spins. When reels are spun, value-bearing symbols that land on the array trigger a tagging process, marking their positions for subsequent interactions.
This creates a persistence-driven mechanic where symbol positions retain state across spins and interact dynamically with new outcomes. The clustering logic further enhances complexity by linking neighboring tagged positions into unified events.
Why it matters
The persistence feature transforms gameplay from a series of independent spins into a stateful, evolving system, increasing player engagement through continuity and anticipation. Players are incentivized to follow how tagged positions develop over time, creating a stronger sense of progression and reward buildup.
Technically, the design introduces a structured way to manage state retention and interaction without significantly increasing computational overhead. By using tagging and controlled untagging mechanisms, the system maintains efficiency while enabling more sophisticated gameplay logic. For operators, this feature enhances retention and session duration by adding depth without altering core payout frameworks. For players, it delivers a more immersive experience where outcomes are interconnected rather than isolated.
The patent, titled “Gaming machine and method with persistence feature,” was filed on June 27, 2022, and granted on June 4, 2024. The listed inventor is Kenneth Shawn Soong.
