Solution Overview

Problem

Conventional game machines fail to stimulate player curiosity and anticipation due to the predictability of bonus spins, making it difficult to maintain player engagement.

Innovation Solution

A game machine with a reel display module providing a changing and static display of symbols, a measuring module tracking the number of special symbol appearances, and a game points determining module awarding points based on this count, along with random selection of special and sub-symbols, to create unpredictability and increase player interest.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a special reel is used to provide bonus spins based on predetermined symbol combinations, then the game machine can award multiplication factors and bonus payouts, but the player's curiosity and anticipation decrease because the procedure becomes widely known and predictable

Engineering Contradiction:
Improvebonus award reliabilityVSAvoidplayer engagement adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the static, predetermined bonus procedure into a dynamic system where the special symbol changes with each game. The symbol that triggers bonus awards is randomly selected and changes dynamically, preventing players from predicting when bonuses will occur. This dynamic adaptation maintains player curiosity while preserving the reliability of bonus awards through the counting mechanism.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the key parameter of the bonus trigger from fixed symbol combinations to a variable special symbol. The special symbol is randomly selected from multiple symbols and changes with each game, fundamentally altering how bonus awards are triggered. This parameter change makes the bonus procedure unpredictable while maintaining its reliability through the underlying counting system.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the bonus procedure is made unpredictable by changing the special symbol, then player curiosity and anticipation increase, but the conventional fixed procedure that determines game points becomes less reliable

Engineering Contradiction:
Improvegame variabilityVSAvoidgame point determination reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a feedback mechanism where the system continuously counts the number of times the special symbol appears during the changing display phase. This count is fed back to determine the game points awarded. The feedback loop ensures that even though the special symbol changes, the game point determination remains reliable and consistent with the actual symbol frequency observed during play.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces a counting mechanism as an intermediary between the variable special symbol display and the game point determination. The counter accumulates symbol appearances during the changing phase and serves as the basis for awarding game points. This intermediary ensures that the unpredictable symbol selection does not compromise the reliability of point determination, as points are based on actual observed frequency rather than fixed rules.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If game points are awarded based on fixed symbol combinations, then the determination procedure is simple and reliable, but player interest decreases due to predictability

Engineering Contradiction:
Improvedetermination procedure complexityVSAvoidplayer interest adaptation
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent performs preliminary counting of special symbol appearances during the changing display phase before determining game points. The system accumulates the count of special symbol occurrences while the reels are spinning, and then uses this pre-calculated count to determine the award. This preliminary action simplifies the final determination step while maintaining player interest through the unpredictable special symbol mechanism.

Inventive Principle:
Principle #10Preliminary action
