Solution Overview

Problem

Wagering games, such as slot games, appear random and repetitive, leading to player boredom and reduced engagement.

Innovation Solution

Implementing a mechanism to lock symbols during a play of a slot game, ensuring they are displayed in subsequent plays, thereby creating a connection between game sessions and enhancing player engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If symbols are locked to ensure continuity across game sessions, then player engagement and retention are improved, but the randomness and replayability of the slot game are reduced

Engineering Contradiction:
Improveplayer engagementVSAvoidgame randomness
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary action by locking symbols before the next game session begins. When a trigger symbol appears during a session, the system identifies and locks associated symbols in advance, ensuring they will appear in the next session. This creates continuity and engagement while maintaining the structural integrity of the random number generator for other symbols.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If a symbol locking mechanism is implemented to create continuity, then player attraction increases, but the simplicity of the slot game operation is reduced

Engineering Contradiction:
Improveplayer attractionVSAvoidgame simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The symbol locking mechanism operates autonomously through self-service logic. The system automatically detects trigger symbols, identifies associated symbols based on predefined relationships, locks them, and ensures their appearance in subsequent sessions without requiring player intervention or complex manual controls. The complexity is hidden within the system logic while maintaining simple player interaction.

Inventive Principle:
Principle #25Self-service

AI summary

An electronic gaming machine (“EGM”) can display a grid of symbols as part of a slot game. The EGM can further determine that the grid of symbols includes a trigger symbol. The EGM can further determine that the grid of symbols includes a symbol associated with the trigger symbol. The EGM can further, responsive to determining that the grid of symbols includes the symbol associated with the trigger symbol and that the grid of symbols includes the trigger symbol, lock the symbol.
