Solution Overview

Problem

Gaming machines lack features that provide additional opportunities for players to win, limiting the excitement and engagement in game play.

Innovation Solution

Implementing a mirror operation in slot machines where symbols are repositioned relative to a predetermined mirror symbol, allowing for additional symbol combinations to be evaluated for wins, which can trigger after a first evaluation or at predetermined intervals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional slot machine operations are used, then the game play is simple and easy to understand, but the player engagement and win opportunities are limited

Engineering Contradiction:
Improvewin opportunitiesVSAvoidgame operation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The slot machine evaluation process is segmented into multiple independent evaluation rounds. After the initial reel spin evaluation, a mirror operation is performed to create a mirrored version of the symbol array, which then undergoes a separate evaluation. This segmentation allows the system to provide additional win opportunities without requiring the player to understand complex new operations, as each evaluation round follows the same win evaluation logic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mirror operation is performed as a preliminary action between the initial reel spin and the final outcome determination. By creating the mirrored symbol array and evaluating it before finalizing the game result, the system adds an additional layer of potential wins without requiring the player to manually trigger or understand the mirroring process, thus maintaining simplicity while enhancing engagement.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If additional game features are added to improve player engagement, then win opportunities increase, but the game play complexity increases

Engineering Contradiction:
Improvegame featuresVSAvoidgame play ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The mirror operation is implemented as an automatic self-service feature that the system performs without requiring player input. After the initial reel spin, the system automatically creates a mirrored version of the symbol array and evaluates it for wins. This allows the game to provide enhanced features and additional win opportunities while maintaining ease of operation, as the player simply needs to trigger the spin and the system handles the complexity automatically.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If mirror operation is implemented to provide additional win opportunities, then player engagement improves, but the processing time and complexity increase

Engineering Contradiction:
Improvewin opportunitiesVSAvoidgame processing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The mirror operation is performed as a preliminary computational step that leverages the already-determined symbol positions from the initial reel spin. Rather than requiring a separate physical spin or extensive processing, the system creates a mirrored version of the existing symbol array and evaluates it. This preliminary action approach minimizes additional processing time while still providing the benefit of additional win evaluation opportunities.

Inventive Principle:
Principle #10Preliminary action
