Persistent Dual Symbol Management in Electronic Gaming Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Implementing persistent wild and prize dual symbols in electronic gaming systems poses challenges, such as negative impact on award probability when a persistent dual symbol covers wild or bonus symbols, and requires separate symbol position determination within a display matrix.
Innovation Solution
The system generates and displays dual symbols that act as both wild and credit on reel symbols, persisting between reel spins by moving up a row or remaining stationary, and dynamically replaces wild or bonus symbols to maintain award probability, with trigger symbols activating credit prizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If persistent dual symbols are implemented in electronic gaming systems, then symbol persistence and prize activation capability are improved, but award probability decreases when dual symbols cover wild or bonus symbols
Solution Approach 1:
The system dynamically adjusts symbol behavior based on game state. Wild symbols and bonus symbols are replaced when a dual symbol would cover them, ensuring that the persistent dual symbol does not permanently block high-value symbol functions. This dynamic replacement resolves the contradiction by allowing symbol persistence while maintaining award probability through adaptive symbol management.
Solution Approach 2:
The system changes the state parameters of symbols based on their position and function. When a dual symbol is determined to cover a wild or bonus symbol, the system modifies the symbol arrangement by replacing the covered symbol, thereby changing the configuration parameters to maintain optimal award probability while preserving the dual symbol's persistent prize activation capability.
2Ease of operation
If separate symbol position determination is implemented for persistent dual symbols, then symbol position control is improved, but system complexity increases
Solution Approach 1:
The system merges the position determination logic for persistent dual symbols with the existing symbol evaluation framework. By integrating the position control mechanism into the overall game logic rather than implementing it as a separate independent system, the patent achieves precise symbol position control while minimizing the increase in system complexity through unified processing.

AI summary
An electronic gaming device that includes a display device, an input device, a memory device, and a processor is described. The processor causes to be displayed a dual symbol configured as a wild symbol and as a credit on reel (or cash-on-reel) symbol that indicates a prize to be awarded if a trigger symbol also lands in the same row as the dual symbol. The processor causes a base game to be initiated that includes causing symbols to be displayed on reels within a display matrix on a display device wherein each reel is configured to spin. During game play of the base game, the dual symbol, if displayed, persists between different reel spins and moves up one row each reel spin from a previous symbol position to a new symbol position.
