Solution Overview

Problem

Existing gaming systems have static average expected payback percentages, limiting player interaction and award opportunities based on fixed reel configurations.

Innovation Solution

The gaming system employs dynamically expanding and contracting reels based on the occurrence of reel expansion events, adding or removing symbol display positions to alter the average expected payback percentage and enhance player interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If reels are kept in a fixed configuration, then the system is simple to operate and understand, but the average expected payback percentage remains static and player engagement is limited

Engineering Contradiction:
Improvedynamic reel configurationVSAvoidreel expansion mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic reel configurations where reels can expand to include additional symbol display positions or contract to fewer positions based on game events. This allows the gaming system to adapt the reel structure during play, changing from a static to a dynamic configuration that responds to game conditions and enhances player engagement while maintaining operational simplicity through automated control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of reel configuration by adding or removing symbol display positions on reels based on triggered events. This parameter change allows the average expected payback percentage to be dynamically adjusted during gameplay, transforming the fixed structural parameter into a variable one that responds to game conditions without requiring complex manual intervention.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If reels are dynamically expanded and contracted, then player engagement and award opportunities increase, but the system complexity increases

Engineering Contradiction:
Improveaward generation rateVSAvoiddynamic reel control system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The gaming system automatically manages the expansion and contraction of reels based on predetermined game events and conditions. The system self-regulates the reel configuration without requiring external intervention, automatically adjusting the number of symbol display positions to maximize award opportunities and player engagement while maintaining controlled complexity through automated decision-making algorithms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from game events and player actions to dynamically adjust reel configurations. When specific events occur during gameplay, the system receives feedback and responds by expanding or contracting reels accordingly, creating a responsive loop that increases award generation rate while managing system complexity through event-driven control rather than continuous manual adjustment.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If the average expected payback percentage is adjusted dynamically, then player interaction is enhanced, but the predictability of game outcomes decreases

Engineering Contradiction:
Improvepayback percentage adjustmentVSAvoidoutcome predictability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system adjusts the average expected payback percentage periodically based on predetermined game events rather than continuously or randomly. This periodic adjustment maintains certain predictability by following a structured pattern tied to specific game conditions, while still enhancing player interaction through dynamic changes. The payback percentage changes at defined intervals or event triggers rather than unpredictably.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent changes the parameter of average expected payback percentage by dynamically adjusting reel configurations. This parameter change is implemented through controlled modifications to the number of symbol display positions, which systematically alters the probability distribution and expected payback while maintaining a degree of predictability through the structured nature of the configuration changes.

Inventive Principle:
Principle #35Parameter changes
