Solution Overview

Problem

Conventional gaming machines lack features that sustain player interest and engagement in free games, leading to a monotone experience and potential unfairness due to prolonged gameplay.

Innovation Solution

A gaming machine that generates free games based on the number of predetermined symbols stopped during a normal game, allowing additional free games when fewer symbols are stopped, and displays numeric values to enhance player engagement and satisfaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If free games are executed for a specific number of times when N or more predetermined symbols are stop-displayed, then player expectation is increased, but the game may become monotone and lead to infinite gameplay

Engineering Contradiction:

Improvefairness of gameVSAvoidnumber of free games

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent applies dynamics by making the free game execution count variable rather than fixed. The controller dynamically adjusts the number of free games based on the number of stop-displayed predetermined symbols, allowing the game duration to adapt to player performance while maintaining fairness through defined retrigger conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of free game count from a static value to a dynamic value that depends on the number of stop-displayed symbols. When 1 or more but fewer than N predetermined symbols are stop-displayed during free games, the controller adds a numeric value equivalent to the count of stop-displayed symbols to the free game execution count, creating a flexible yet controlled gameplay experience.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If additional free games are added when 1 or more and (N-1) or less predetermined symbols are stop-displayed, then player engagement is increased, but game complexity increases

Engineering Contradiction:

Improveplayer engagementVSAvoidgame control logic

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies partial action by allowing free games to be triggered not only by the full condition of N or more symbols but also by partial conditions of 1 or more but fewer than N symbols. This creates a graduated reward system that maintains player engagement while using a relatively simple counting mechanism to determine additional free games.

Inventive Principle:

Principle #16Partial or excessive action

3Adaptability or versatility

If the number of free games is increased dynamically, then player interest is raised, but profit loss for the facility may occur

Engineering Contradiction:

Improveplayer interestVSAvoidprofit loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent implements feedback by continuously monitoring the number of stop-displayed predetermined symbols during free games and adjusting the free game execution count accordingly. This feedback mechanism allows the system to respond to player performance in real-time, increasing interest while maintaining control over the maximum number of free games through the retrigger condition of N or more symbols.

Inventive Principle:

Principle #23Feedback

AI summary

According to a gaming machine 1 of the present invention, a specific number of free games are generated when three or more trigger symbols 100 have been stop-displayed in a normal game. Further, when one or two trigger symbols 100 have been stop-displayed in a free game, numeric values in number equivalent to the number of stop-displayed trigger symbols 100 are selected, and then the number of times obtained by summing up the selected numeric values is added to the number of free games.
