Solution Overview

Problem

Existing gaming systems lack variability in the number of ways to win and volatility in game outcomes, leading to predictable and unengaging gameplay experiences.

Innovation Solution

A gaming system that randomly determines the quantity of active symbol display positions for each reel, using these positions to dynamically alter the number of ways to win and apply modifiers during symbol accumulation sequences, enhancing gameplay variability and volatility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed number of symbol display positions is used for each reel, then the game structure is simple and easy to operate, but the number of ways to win is limited and gameplay is predictable

Engineering Contradiction:
Improvenumber of ways to winVSAvoidgame structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the number of active symbol display positions variable rather than fixed. The system randomly determines the quantity of active symbol display positions for each reel before each play, allowing the number of ways to win to change dynamically from play to play. This creates unpredictability and increases engagement while maintaining a relatively simple basic game structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of symbol display positions from a fixed value to a randomly determined variable value. By randomly determining the quantity of active symbol display positions for each reel before each play, the system varies the number of ways to win without fundamentally changing the game structure, thus resolving the contradiction between versatility and complexity.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the quantity of active symbol display positions is randomly determined, then volatility and gameplay variability are increased, but the complexity of determining awards and modifiers increases

Engineering Contradiction:
Improvegameplay variabilityVSAvoidaward determination process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary action by randomly determining the quantity of active symbol display positions for each reel before the play begins. This pre-determination establishes the framework for award evaluation before symbols are spun and evaluated, simplifying the subsequent award determination process while still achieving gameplay variability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the randomly determined quantity of active symbol display positions to evaluate awards and determine modifiers. The evaluation process incorporates feedback about which symbol display positions are active, allowing the system to dynamically adjust awards and modifiers based on the random configuration while maintaining a systematic evaluation approach.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If modifiers are applied based on randomly determined symbol display positions, then award variability increases, but the complexity of tracking and applying modifiers increases

Engineering Contradiction:
Improveaward variabilityVSAvoidmodifier tracking
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by assigning modifiers to specific reels based on their individually determined quantities of active symbol display positions. Each reel receives a modifier corresponding to its specific quantity, allowing localized variation in award multipliers without requiring complex global tracking. This simplifies modifier application while maintaining award variability.

Inventive Principle:
Principle #3Local quality

AI summary

Gaming systems and methods that randomly determine a quantity of ways to win for a play of a game by randomly determining a quantity of active symbol display positions to employ for that play of the game and then, responsive to a triggering event, utilize the randomly determined quantity of active symbol display positions to determine one or more modifiers employed for a symbol accumulation sequence.
