Solution Overview

Problem

Existing gaming machines lack engaging and dynamic gameplay experiences, failing to attract and retain casino customers effectively.

Innovation Solution

A gaming machine that includes a display device and a control unit to render animated sequences of computer-generated images, animating virtual reels to simulate spinning and stopping, and dynamically transforming the reel window size based on game outcomes to enhance gameplay interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the reel window size is fixed, then the game structure is simple, but the gameplay becomes repetitive and less engaging

Engineering Contradiction:
Improvegameplay dynamicsVSAvoidreel window transformation mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The reel window size is made dynamic rather than fixed. The system automatically adjusts the reel window size based on game outcomes, transforming between different sizes (e.g., 3x3, 4x4, 5x5) to create varying gameplay experiences. This dynamic adaptation resolves the contradiction by making the gameplay more engaging while managing complexity through automated control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The reel window size parameter is changed based on game outcomes. When special symbols appear or specific winning combinations are achieved, the system modifies the reel window size parameter for subsequent spins. This parameter change mechanism enables gameplay diversity without requiring complex manual intervention.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the reel window size changes dynamically, then player engagement increases, but the control system becomes more complex

Engineering Contradiction:
Improvegameplay varietyVSAvoidcontrol algorithm
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control system uses feedback from game outcomes to automatically adjust reel window size. When players achieve certain results (e.g., landing special symbols, winning combinations), the system receives feedback and responds by transforming the reel window size accordingly. This feedback loop creates gameplay variety while keeping the control system manageable through rule-based automation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-adjustment of the reel window size based on predefined criteria and game outcomes. Rather than requiring external intervention or complex real-time analysis, the system autonomously determines when and how to transform the reel window, simplifying the overall control architecture while maintaining gameplay variety.

Inventive Principle:
Principle #25Self-service

3Productivity

If additional rows are added to the reel window, then more winning combinations are possible, but the rendering complexity increases

Engineering Contradiction:
Improvewinning combination possibilitiesVSAvoidimage rendering system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system changes the dimensional configuration of the reel window by adding or removing rows (e.g., transitioning from 3 rows to 4 or 5 rows). This dimensional change enables more winning combination possibilities while using the same fundamental rendering engine, avoiding the need to develop entirely new rendering systems for different configurations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A gaming machine including a cabinet, a display device mounted to the cabinet, and a control unit operably coupled to the display device is described herein. The control unit includes a processor programmed to execute an algorithm to render an animated sequence of computer-generated images on the display device including the steps of rendering a primary game screen on the display device including a plurality of virtual reels displayed within a reel window including a plurality of cells arranged in a plurality of rows and columns. The processor transforms the reel window by animating the reel window to increase a size of the reel window to display an additional row of cells within the reel window upon determining the game outcome displays a special symbol within the reel window. The processor also decreases the size of the reel window upon determining the game outcome does not display the special symbol.
