Solution Overview

Problem

Gaming machines often fail to maintain player interest due to the infrequent appearance of wild symbols, leading to frustration and reduced playtime.

Innovation Solution

A method and apparatus for gaming machines that display reels with consecutive special symbol positions, randomly generating and replacing symbols to create additional winning opportunities without re-spinning, thereby increasing player engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wild symbols are used to represent any other symbol, then symbol substitution capability is improved, but appearance frequency deteriorates

Engineering Contradiction:
Improvesymbol substitution capabilityVSAvoidappearance frequency
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The wild symbol functionality is segmented into two distinct types: first special symbols that substitute for specific symbol types (e.g., all fruit symbols), and second special symbols that substitute for any symbol. This segmentation allows each type to have optimized appearance frequencies while maintaining overall substitution capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the reel strip are assigned different symbol types with different substitution properties. First special symbols are placed in certain positions with limited substitution scope, while second special symbols are placed in other positions with universal substitution scope, creating local variations in symbol quality and behavior.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If conventional reel spinning is used, then game simplicity is improved, but player engagement deteriorates

Engineering Contradiction:
Improvegame simplicityVSAvoidplaytime
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The system performs preliminary actions by pre-positioning first special symbols in the reel strip before the spin. During the spin, these symbols are automatically substituted with second special symbols when triggering conditions are met, eliminating the need for additional spin actions while providing enhanced gameplay.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The symbol substitution feature provides continuous useful action during a single spin sequence. Instead of requiring separate spin actions to achieve symbol replacements, the system continuously monitors and substitutes symbols based on triggering conditions, extending the useful action within the same game cycle.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If symbol replacement feature is added, then winning frequency is improved, but game complexity deteriorates

Engineering Contradiction:
Improvewinning frequencyVSAvoidgame complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The game structure transitions from static reel strips to dynamic symbol replacement. First special symbols are initially positioned in the reel strip, then dynamically replaced with second special symbols when triggering conditions occur during the spin, creating a dynamic gameplay experience without complex additional mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

First special symbols serve as intermediaries between the static reel strip configuration and the dynamic second special symbols. They are pre-positioned in the reel strip and act as placeholders that are subsequently replaced by second special symbols, mediating the transition between fixed and dynamic game elements.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method of allowing a player to play a gaming machine is described herein. The method includes the steps of displaying a game including a plurality of reels including a reel strip having a plurality of normal symbols positions and a plurality of special symbol positions. The method includes randomly generating a first outcome of a game, responsively awarding a first award to the player based on the first game outcome, and determining if a triggering condition occurs in the first game outcome, wherein the triggering condition including a plurality of adjacent special symbol positions being displayed in at least one reel within the display area. The method includes randomly selecting a special symbol and replacing the symbols being displayed in each adjacent special symbol position with the selected special symbol to generate a subsequent second game outcome including the selected special symbol.
