Solution Overview

Problem

Gaming systems lack innovative features to enhance player engagement and excitement, with existing slot games offering limited variations and no mechanism for dynamic re-spinning of reels based on triggering events.

Innovation Solution

A gaming system that introduces a partial reel re-spin feature, where upon a triggering event, a designated set of symbol display areas is selected based on proximity to the triggering symbol, and the symbols in these areas are replaced with new ones, allowing for additional award determinations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional slot game is played with fixed reels, then the game structure is simple and easy to understand, but player engagement and excitement are limited

Engineering Contradiction:
Improvegame mechanic varietyVSAvoidreel spinning mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The reel set is divided into multiple individual reels that can be independently controlled. When a triggering symbol appears, only the specific reels containing the triggering symbol are selected for re-spinning, while other reels remain stationary. This segmentation allows the system to add complexity only where needed rather than requiring all reels to be re-spun.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reel spinning mechanism transitions from a static, all-or-nothing approach to a dynamic, selective approach. The system determines which reels should re-spin based on the position and type of triggering symbols, creating adaptive game behavior that responds to game state rather than following a fixed pattern.

Inventive Principle:
Principle #15Dynamics

2Productivity

If all reels are re-spun after a triggering event, then additional award opportunities are maximized, but the game becomes less engaging due to lack of strategic elements

Engineering Contradiction:
Improveaward determination frequencyVSAvoidgame feature innovation
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

Instead of re-spinning all reels (excessive action) or no reels (insufficient action), the system re-spins only the partial set of reels that contain triggering symbols. This partial action is precisely calibrated to provide additional award opportunities while maintaining game variety and player engagement.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

Different regions of the reel set receive different treatments based on their content. Reels containing triggering symbols are selected for re-spinning, while reels without triggering symbols remain stationary. This local differentiation creates strategic depth and maintains player engagement while still providing multiple award determination opportunities.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the slot game includes no bonus features, then the game is simple to operate, but player excitement and engagement are reduced

Engineering Contradiction:
Improvebonus game featuresVSAvoidgame play simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system identifies and locks triggering symbols in place before initiating the re-spin sequence. This preliminary action preserves the original game state while setting up the bonus feature, allowing players to understand what triggered the bonus without losing track of the overall game progress.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The triggering symbol acts as an intermediary between the base game and the bonus re-spin feature. It initiates the bonus sequence while its locked position serves as a reference point, connecting the simple base game mechanics with the more complex bonus feature and maintaining operational clarity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present disclosure provides a gaming system and method providing a slot game including a partial reel re-spin feature. Generally, for a play of the slot game in various embodiments, the gaming system displays a randomly determined plurality of symbols of a first set of symbols at a plurality of symbol display areas and makes an award determination based on the displayed symbols. Upon an occurrence of a triggering event, such as the display of a triggering symbol, the gaming system selects a designated set of a plurality of the symbol display areas and replaces the symbols of the first set of symbols displayed at the symbol display areas of the designated set with symbols from a second set of symbols, which may be the same as or different than the first set of symbols. The gaming system makes another award determination based on the displayed symbols.
