Solution Overview

Problem

Existing gaming systems lack the ability to provide independently determined symbol pattern sets that enhance player engagement and persistence features without altering the primary game mechanics.

Innovation Solution

A gaming system that randomly determines and displays symbol pattern sets separate from symbol display elements, allowing for the removal of symbols based on positional correspondence, with features like replacement, movement, and termination events to provide additional awards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If symbol pattern sets are determined independently of symbol display elements, then player engagement and persistence features are enhanced, but device complexity increases

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

Solution Approach 1:

The system separates the symbol pattern set determination from the symbol display element determination, creating two independent subsystems. The symbol pattern set is determined independently and then associated with symbol display positions, allowing each subsystem to operate autonomously while maintaining their relationship through positional association.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The symbol pattern set is nested within the gaming system structure but operates independently from the symbol display elements. The pattern set contains multiple symbols that can be removed based on correspondence with displayed symbols, creating a layered structure where the pattern set is contained within but independent from the display system.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Quantity of substance

If multiple symbol pattern sets are provided with removal features, then award opportunities are enhanced, but game mechanics complexity increases

Engineering Contradiction:
Improveaward opportunitiesVSAvoidgame mechanics
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The symbol pattern set is determined and displayed in advance before the symbol display elements are determined. This preliminary determination allows the system to prepare multiple potential award patterns that will be evaluated against future symbol displays, creating pre-configured award opportunities without complicating the actual game play mechanics.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a symbolic representation (pattern set) that mirrors the structure of potential symbol displays but operates independently. The pattern set symbols correspond positionally to display positions, creating a simplified model that can be evaluated without directly complicating the main game mechanics.

Inventive Principle:
Principle #26Copying

3Duration of action of stationary object

If symbols are removed from pattern set based on positional correspondence, then persistence features are improved, but measurement and detection difficulty increases

Engineering Contradiction:
ImprovepersistenceVSAvoidsymbol correspondence detection
Core Design Contradiction:
Duration of action of stationary objectVSDifficulty of detecting and measuring

Solution Approach 1:

The system continuously evaluates the correspondence between displayed symbols and the symbol pattern set, providing feedback on which pattern set symbols remain and which have been removed. This feedback mechanism maintains persistence by tracking the state of the pattern set across multiple game cycles while simplifying detection through systematic comparison at each evaluation point.

Inventive Principle:
Principle #23Feedback

AI summary

Gaming systems and methods that independently randomly determine and display one or more symbol pattern sets associated with symbol display positions for multiple plays of a game. The gaming system displays each determined symbol pattern set adjacent to the symbol display positions. At various points during the multiple plays of the game, the gaming system removes one or more of the symbols of each of the symbol pattern sets based on and corresponding to one or more of the symbols displayed on symbol display elements at the symbol display positions. Responsive to all of the symbols of one of the symbol pattern sets being removed, the gaming system displays an indication of an award associated with that symbol pattern set.
