Metamorphic Reel Symbol Expansion Under Fixed Slot Display Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Class II electronic gaming machines face challenges in expanding metamorphic symbols while adhering to display dimensions, volatility, and return-to-player (RTP) targets, which complicates user interface and regulatory compliance.
Innovation Solution
The metamorphic symbols are controllably expanded in size, deforming surrounding walls, and their values are distributed to adjacent symbols, enhancing player engagement and satisfaction while maintaining volatility and RTP targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If metamorphic symbols are expanded in size to enhance player engagement, then player excitement and satisfaction increase, but display dimension constraints and interface complexity worsen
Solution Approach 1:
The reel walls are made dynamically deformable rather than static, allowing them to flex and bend as metamorphic symbols expand. This dynamic behavior enables the display to accommodate size changes of symbols without exceeding display boundaries, resolving the contradiction between symbol expansion and display dimension constraints
Solution Approach 2:
The solution transitions from a rigid 2D grid layout to a flexible spatial arrangement where reel walls can bend and deform in intermediate dimensions. This allows symbols to expand visually while the deformed walls redirect the expansion within the display boundaries, effectively adding a dimensional flexibility that resolves the area constraint
2Reliability
If metamorphic symbols are expanded to control volatility and RTP targets, then game outcome control improves, but device complexity and rule complexity worsen
Solution Approach 1:
The deformable reel walls provide a dynamic visual mechanism that automatically reflects the expansion state of metamorphic symbols. This visual feedback system simplifies the interface by showing players the progression toward award states through wall deformation, reducing the need for complex rule explanations while maintaining volatility and RTP control
Solution Approach 2:
The reel walls change their visual properties (deformation state) in response to symbol expansion, providing intuitive visual information about game state progression. This visual encoding simplifies the interface by making complex volatility and RTP mechanics observable through wall deformation patterns rather than requiring complex rule sets
3Shape
If metamorphic symbols expand and deform surrounding walls, then visual transformation and player excitement increase, but manufacturing complexity and compliance difficulty worsen
Solution Approach 1:
The solution changes the parameter of reel wall rigidity from fixed to variable, allowing walls to deform in response to symbol expansion. This parameter change enables the desired visual transformation while maintaining compliance with display dimension constraints, as the deformation automatically keeps symbols within boundaries
Solution Approach 2:
The deformable reel walls provide a dynamic system that automatically adapts to symbol size changes. This dynamic behavior simplifies compliance with display constraints because the walls naturally prevent symbols from exceeding boundaries, reducing the need for complex manufacturing tolerances and compliance verification

AI summary
Disclosed are video slot games, including Class II and III gaming machines and systems, comprising a five reel video (5RV) arrangement that includes metamorphic symbols that incrementally expand, enlarge, balloon, widen, lengthen, or grow, e.g., when the metamorphic symbol lands on a predetermined position, or a winning payline, and that communicate the effect to the player of the incremental growth or increase in size by providing an enhanced user interface with information about the player's progress toward a potential special awards or status. The metamorphic symbols may incrementally expand, enlarge, balloon, widen, lengthen, or grow with each successive winning land, and may, in some examples, ultimately snap, crack, pop, deflate, or explode, while optionally deforming adjacent presentations to provide various award enhancements.
