Solution Overview

Problem

Existing gaming systems lack a dynamic and engaging mechanism for symbol replacement in games that enhances player interaction and award determination based on sub-value comparisons.

Innovation Solution

A gaming system that employs a processor to display reels with symbols having sub-values, allowing for symbol comparisons and replacements based on these sub-values, ultimately determining winning combinations and awards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If symbol replacement is implemented in existing gaming systems, then player engagement and award determination are enhanced, but the system complexity and computational requirements increase

Engineering Contradiction:
Improveplayer engagementVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The symbol comparison mechanism is segmented into discrete sub-value comparisons between adjacent symbols on reels. Each symbol is divided into comparable sub-value components, allowing the system to process replacements in manageable units rather than evaluating entire symbol sets simultaneously, thus reducing computational complexity while maintaining engagement enhancement

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Sub-values are pre-assigned to symbols before the gaming round begins. This preliminary assignment of numerical values to symbols allows the system to perform simple numerical comparisons during gameplay rather than complex symbol evaluation, reducing real-time computational requirements while enabling dynamic replacement mechanics that enhance player engagement

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If sub-value comparisons are performed between adjacent symbols, then award determination becomes more dynamic, but the processing time and computational load increase

Engineering Contradiction:
Improveaward determinationVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces complex mechanical symbol evaluation mechanisms with numerical sub-value comparisons. Instead of evaluating entire symbol graphics and patterns, the system substitutes this with simple numerical comparisons of pre-assigned sub-values, dramatically reducing processing time while maintaining dynamic award determination capabilities

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the parameter of symbol evaluation from graphical/pattern-based assessment to numerical value comparison. By converting symbol evaluation into a numerical parameter comparison task, the system achieves faster processing while enabling more dynamic and varied award determination through the replacement mechanism

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If symbols with sub-values are displayed on reels, then replacement mechanics become more engaging, but the display complexity and information presentation increase

Engineering Contradiction:
Improvereplacement mechanicsVSAvoiddisplay complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of displaying complex information for all symbols uniformly, the system applies local quality by showing sub-value information selectively - typically only for symbols that are candidates for replacement or that have just been replaced. This localized information presentation maintains engaging replacement mechanics while reducing overall display complexity and information overload

Inventive Principle:
Principle #3Local quality

AI summary

Gaming systems and methods that provide a symbol replacement based on sub-value comparisons feature for a play of a game. In various embodiments, for the play of the game, for each of a plurality of symbol display elements, the gaming system sequentially causes the display of a current symbol on that symbol display element, and determines whether to change one or more previously displayed symbols based on zero, one, or more comparisons of respective sub-values for that current symbol and the previously displayed symbols.
