Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing gaming devices face inefficiencies in processing numerous game outcomes to meet target volatility and RTP criteria, particularly when initiating feature games based on trigger symbols, and struggle to effectively communicate feature game opportunities in confined screen spaces.

Innovation Solution

A gaming device with a random number generator that initiates feature games based on a threshold number of trigger symbols, allowing additional game instances when less than the threshold is met, and uses visual indicators to communicate progress towards feature games.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the gaming device processes numerous game outcomes to meet target volatility and RTP criteria, then the game fairness and regulatory compliance are improved, but the processing time and computational resources increase

Engineering Contradiction:

Improvegame fairnessVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-determining game outcomes and volatility adjustments before actual gameplay occurs. The processor calculates and sets target volatility and RTP parameters in advance, allowing efficient processing during actual play without compromising fairness.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts game parameters such as volatility targets, RTP percentages, and trigger thresholds based on current gameplay conditions. This allows the system to meet regulatory requirements while optimizing processing efficiency by adapting parameters rather than following fixed rigid rules.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If the gaming device initiates feature games based on trigger symbols, then player engagement is improved, but the complexity of game outcome processing increases

Engineering Contradiction:

Improveplayer engagementVSAvoidgame outcome processing complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system segments the game into distinct phases: base game play, trigger symbol detection, and feature game initiation. By separating these functions, the processor can handle each phase independently, reducing overall processing complexity while maintaining engaging feature game opportunities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Trigger symbols act as intermediaries between the base game and feature games. Instead of directly managing complex feature game logic during base play, the system uses trigger symbols as simple, recognizable mediators that initiate appropriate feature sequences, simplifying the overall processing architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the gaming device uses a random number generator to determine feature game initiation, then the randomness and fairness are improved, but the resource consumption increases

Engineering Contradiction:

ImproverandomnessVSAvoidresource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system uses partial random number generation only when necessary - specifically when trigger symbols are detected and feature game initiation is uncertain. Rather than continuously generating random outcomes, the RNG is activated selectively, reducing computational resource consumption while maintaining fairness where needed.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The random number generator is integrated into the existing game processing architecture, allowing it to serve dual purposes: determining base game outcomes and triggering feature sequences. This self-service approach eliminates the need for separate resource-intensive random determination systems.

Inventive Principle:

Principle #25Self-service

4Loss of information

If the gaming device displays multiple feature game options on the screen, then player information is improved, but the screen space requirements increase

Engineering Contradiction:

Improvefeature game informationVSAvoidscreen space

Core Design Contradiction:

Loss of informationVSArea of stationary object

Solution Approach 1:

The system transitions from displaying all feature game options simultaneously on the screen to presenting information in a sequential or hierarchical manner. Feature game details are revealed dimensionally - first through trigger symbol indicators, then through detailed displays only when needed, reducing screen space requirements while maintaining information availability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
