Solution Overview

Problem

Existing gaming machines struggle to effectively implement hidden symbol features, particularly in mechanical machines, which can limit player engagement and suspense compared to digital machines.

Innovation Solution

A gaming system and method that utilizes a hidden symbol on a reel, capable of different presentations based on varying lighting conditions, along with a lighting system and controller to coordinate the lighting with the reel's rotation, enhancing the hidden symbol reveal feature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a hidden symbol feature is implemented in a mechanical machine, then player engagement and suspense are improved, but the device complexity increases due to the need for additional lighting systems and coordination mechanisms

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

Solution Approach 1:

The patent applies dynamics by making the symbol presentation dynamic through lighting conditions. The hidden symbol can be revealed in different ways (fully revealed, partially revealed, or not revealed) based on lighting state, allowing the same physical symbol to present different information states. This dynamic presentation enhances player engagement without requiring multiple physical symbols.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes color changes through lighting conditions to control symbol visibility. By applying different lighting states (lit vs. unlit), the system changes the visual presentation of the hidden symbol, enabling multiple presentation states from a single symbol. This optical transformation provides versatility in symbol display while avoiding the complexity of multiple physical symbols.

Inventive Principle:
Principle #32Color changes

2Manufacturing precision

If multiple presentations of the hidden symbol are provided through lighting conditions, then the hidden symbol reveal quality is improved, but the use of energy increases due to the lighting system requirements

Engineering Contradiction:
Improvehidden symbol reveal qualityVSAvoiduse of energy
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies periodic action through the sequential revelation of the hidden symbol. The lighting system activates in specific sequences during reel rotation to reveal the symbol at appropriate moments (e.g., when it lands on the payline). This periodic lighting activation provides high-quality reveal moments while limiting total energy consumption compared to continuous illumination.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The hidden symbol system serves itself by using the reel's own rotation and the natural gameplay sequence to trigger symbol revelation. The lighting system activates automatically based on the reel's position and the game state, without requiring additional energy-intensive mechanisms. The system leverages existing mechanical motion to achieve its revelatory function.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides a high-quality, visually appealing hidden symbol reveal, improving player experience and engagement by offering multiple presentations of the hidden symbol, which can influence game play features and bonuses.

Implementation Method 1

AI summary

The present disclosure relates generally to gaming systems, machines, and methods and, in particular, hidden symbol tracking. As an example, an electronic gaming machine is described that includes a set of reels, where each reel in the set of reels includes a plurality of symbol regions with at least one symbol provided therein, and where a first reel in the set of reels includes a hidden symbol that is capable of different presentations based upon having different lighting conditions applied thereto.
