Solution Overview

Problem

Gaming machines with fixed credit values become monotonous over time, failing to maintain player engagement and excitement as the stimulation provided by the game diminishes with prolonged play.

Innovation Solution

A gaming machine that includes an operation unit, display unit, and control unit, which starts a bonus event when a credit symbol is included in the symbol arrangement and accumulates the number of credit symbols, increasing the bonus event award in subsequent games based on the accumulated count, providing a dynamic and stimulating experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the credit amount attached to the prize symbol continues to show a value within a predetermined range with a predetermined probability, then the player can immediately understand the credits they can earn, but the stimulation provided to the player by the game becomes monotonous after long-term play

Engineering Contradiction:
Improveease of following game progressVSAvoidgame stimulation variety
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the credit amount display changeable rather than fixed. The control unit changes the credit amount displayed on the prize symbol based on accumulated game data, transitioning from a static predetermined value to a dynamic value that evolves during prolonged play. This resolves the contradiction by maintaining ease of understanding while introducing variability in stimulation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of the credit amount value displayed on the prize symbol. Instead of using a fixed predetermined range, the system dynamically adjusts the displayed credit amount based on accumulated game results and player activity. This parameter change maintains player engagement by preventing monotony while preserving the clarity of credit accumulation tracking.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If the game uses fixed credit values and predetermined probability ranges, then the game rules are simple and easy to understand, but the game fails to maintain player engagement over extended periods

Engineering Contradiction:
Improvegame rule simplicityVSAvoidplayer engagement duration
Core Design Contradiction:
Device complexityVSDuration of action of stationary object

Solution Approach 1:

The patent implements preliminary action by accumulating game data and player activity information before changing the credit amount display. The control unit continuously monitors and accumulates data during gameplay, then uses this accumulated information to trigger changes in the displayed credit values. This maintains simple initial rules while enabling extended engagement through data-driven dynamic adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces feedback by using accumulated game data and player activity information to dynamically adjust the credit amount display. The control unit continuously monitors gameplay results and uses this feedback to modify the displayed values, creating an adaptive system that maintains player engagement. This feedback mechanism extends the duration of interesting gameplay while keeping the core rules simple.

Inventive Principle:
Principle #23Feedback

AI summary

The gaming machine includes: an operation unit; a display unit configured to display symbols including credit symbols each associated with a predetermined amount of award; and a control unit connected to the operation unit and the display unit, configured to change and stop the symbols displayed by the display unit, and provide an award based on symbol arrangement formed by the symbols stopped in the display unit, wherein the control unit is configured to: start a bonus event when the symbol arrangement includes at least one credit symbol and a predetermined condition is satisfied; provide a bonus event award based on an amount associated with the at least one credit symbol occurred in the symbol arrangement; accumulate the number of the credit symbols occurred in the bonus event; and increase the bonus event award to be provided in subsequent game based on the number of credit symbols accumulated.
