Solution Overview

Problem

Gaming machines with fixed numbers of special symbols on reels can lead to player frustration and decreased interest over time, as the constant number of symbols in each reel results in a lack of excitement and appeal.

Innovation Solution

A gaming machine that displays a grid of symbol regions, where an initial outcome is randomly generated, and upon detecting a triggering condition, replaces initial symbols in predetermined regions with replacement symbols determined by their initial value and the predetermined order of symbols, enhancing the game experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of special symbols in each reel is kept constant, then the game structure remains simple and predictable, but player interest and excitement decrease over time

Engineering Contradiction:
Improvesymbol variabilityVSAvoidgame structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic symbol replacement where initially selected symbols can be upgraded to higher-value symbols based on predetermined rules. This dynamic transformation occurs in a second set of symbol positions, allowing the game to adapt and change during play rather than remaining static, thereby maintaining player interest while preserving overall structural simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary selection of symbols in the first set of positions, then applies predetermined replacement rules to generate upgraded symbols in the second set. This preliminary action establishes a base outcome that can then be enhanced through systematic replacement, creating excitement without requiring complete structural complexity

Inventive Principle:
Principle #10Preliminary action

2Productivity

If symbols are dynamically replaced with higher-value symbols, then player engagement and excitement increase, but the game logic and processing complexity increase

Engineering Contradiction:
Improveplayer engagementVSAvoidgame logic
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The game outcome is segmented into two distinct sets of symbol positions: a first set with initially selected symbols and a second set with replacement symbols. This segmentation allows independent processing of each set, simplifying the overall logic while enabling dynamic symbol replacement to enhance player engagement

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the parameter of symbol value by replacing initial symbols with higher-value replacement symbols according to predetermined rules. This parameter transformation occurs systematically in the second set of positions, increasing excitement through visible upgrades while maintaining manageable game logic through consistent replacement criteria

Inventive Principle:
Principle #35Parameter changes

AI summary

A gaming machine and method allow a player to play a game. The game has an associated set of game symbols. The game symbols in the set of game symbols are arranged in a predetermined order from lowest to highest. A display device is configured to display a plurality of symbol regions arranged in a grid. The controller is configured to randomly select an initial outcome of the game. The initial outcome of the game includes an initial game symbol associated with each of the symbol regions. The controller detects a triggering condition associated with the initial outcome of the game and responsively replaces the initial game symbol in at least one predetermined symbol region with a replacement symbol to establish a secondary outcome of the game. The replacement symbol is determined as a function of the initial symbol and the predetermined order of the game symbols.
