Solution Overview

Problem

Conventional reel games lack flexibility and variability in utilizing special symbols to trigger features, requiring complex computations and limited display space for visual feedback, while maintaining computational efficiency and RTP volatility.

Innovation Solution

Configurable reel strips with different sets of trigger symbols associated with varying probabilities based on wager amounts, using memory to store trigger probability data and visual elements to indicate trigger probabilities, allowing for flexible feature game triggering and efficient computation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional reel games use fixed trigger symbols with fixed probabilities, then the game operation is simple, but the game variability and flexibility are limited

Engineering Contradiction:
Improvegame variabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic reel strip configuration where trigger symbol versions and their probabilities change based on selected wager options. The system transitions from static, fixed probability trigger symbols to dynamic, adjustable probability trigger symbols that adapt to player choices, thereby increasing game variability without requiring complete system redesign

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the probability parameter of trigger symbols based on wager selections. Different wager options correspond to different probability sets for triggering feature games, allowing the system to adjust game characteristics dynamically. This parameter change approach enables flexibility while maintaining a manageable system structure through predefined probability sets

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple sets of trigger symbols with different probabilities are implemented, then the game flexibility increases, but the computational complexity increases

Engineering Contradiction:
Improvewager option flexibilityVSAvoidcomputational complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent pre-configures multiple reel strip sets with different trigger symbol versions and probability distributions before gameplay begins. When a wager option is selected, the system simply loads the corresponding pre-prepared reel strip configuration rather than calculating probabilities in real-time, significantly reducing computational complexity during active gameplay

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent divides the trigger symbols into different versions grouped by wager option. Each wager option has its own segmented set of trigger symbols with specific probability characteristics. This segmentation allows the system to manage complexity by handling one wager-specific configuration at a time rather than managing all configurations simultaneously

Inventive Principle:
Principle #1Segmentation

3Loss of information

If visual elements indicate trigger probabilities, then player information feedback improves, but display space requirements increase

Engineering Contradiction:
Improveinformation feedbackVSAvoiddisplay space
Core Design Contradiction:
Loss of informationVSArea of stationary object

Solution Approach 1:

The patent applies visual indicators locally to specific trigger symbols rather than displaying probability information globally across the entire interface. Each trigger symbol version has distinctive visual characteristics that locally encode probability information, allowing players to understand probability differences without requiring extensive display space for numerical probability values

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses different visual characteristics (such as color, size, or style variations) of trigger symbols to indicate different probability levels. This visual encoding method conveys probability information efficiently within the existing symbol display area, avoiding the need for additional display space while maintaining clear information feedback

Inventive Principle:
Principle #32Color changes

AI summary

A gaming device includes a processor and a memory storing symbol data, trigger probability data for wager options, and instructions. The symbol data includes reel strips including positions dynamically configurable with trigger symbols associated with feature games, and trigger symbol sets including different versions of the trigger symbols and corresponding to the wager options. The instructions, when executed, cause the processor to receive a selected wager option; configure the reel strips by selecting a trigger symbol from the trigger symbol set corresponding to the selected wager option for the dynamically configurable positions; select symbols from the configured reel strips for display in symbol positions; control display of the selected symbols; and upon the selected symbols including a trigger symbol associated with a feature game, determine whether the feature game is triggered based on the trigger probability data for the selected wager option and an identity of the trigger symbol.
