Solution Overview

Problem

Current slot machines lack features that provide players with additional opportunities to win, leading to reduced engagement and gameplay experience.

Innovation Solution

Implementing a symbol lock and re-spin operation in slot machines, where players can lock specific rows or columns during a re-spin, allowing them to maintain original symbols while changing others, enhancing gameplay dynamics and win possibilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional slot machine operation is used, then the game play is simple and easy to understand, but players lack additional opportunities to win and engagement is reduced

Engineering Contradiction:
Improvegameplay featuresVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary evaluation of reel positions and symbol arrangements before the player makes a decision. The processor determines potential re-spin opportunities based on the initial spin outcome, presenting players with pre-analyzed options for locked rows or columns that could lead to winning combinations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The slot machine interface is segmented into distinct functional components: the initial spin display, the re-spin opportunity indicator, the selection interface for locked rows/columns, and the final evaluation display. This segmentation allows players to interact with complex features through simple, discrete choices rather than overwhelming controls.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If re-spin with symbol lock feature is implemented, then players gain additional winning opportunities and engagement increases, but the operation becomes more complex

Engineering Contradiction:
Improvewinning opportunitiesVSAvoidoperation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically performs the complex tasks of evaluating reel positions, determining optimal lock candidates, and managing the re-spin process. Players simply need to select from pre-parsed options presented by the system, which handles the computational complexity of assessing which rows or columns to lock for maximum winning potential.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system provides immediate feedback to players about potential winning opportunities by analyzing the initial spin outcome and presenting re-spin options with locked rows or columns. This feedback loop allows players to make informed decisions about whether to pursue additional spins based on the system's evaluation of their current symbol arrangement.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If multiple reel spins are processed, then more symbol combinations are evaluated, but the time required for game completion increases

Engineering Contradiction:
Improvesymbol evaluationVSAvoidgame completion time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The slot machine uses periodic action by implementing a structured sequence: initial spin, evaluation pause to present re-spin option, player decision, selective re-spin of locked portions, and final evaluation. This periodic structure allows the game to pause at strategic points where the processor can present options without requiring continuous spinning, managing time while maintaining evaluation thoroughness.

Inventive Principle:
Principle #19Periodic action

AI summary

The present disclosure relates generally to computational devices and, in particular, toward a computational device, system, and method of operating a computational device. The method may include determining that a re-spin operation is available with a symbol lock feature and then implementing the re-spin for symbols in an array of symbols that are unlocked or otherwise not identified as being locked.
