Electronic Gaming Device Lookup Tables for Targeted Volatility Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gaming devices face inefficiencies in generating game outcomes that meet target volatility criteria or designated RTP, often requiring repeated random re-spins and extensive data processing to achieve desired payout levels, leading to resource consumption and latency.
Innovation Solution
Implementing reel-specific lookup tables that associate symbol types with reels to dynamically control volatility, allowing for efficient determination of winning combinations that satisfy target thresholds such as RTP and maximum win liability, reducing the need for multiple game outcome evaluations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated random re-spins are used to meet target volatility criteria, then the game outcome satisfies the target RTP and volatility thresholds, but the processing time and computational resources increase significantly
Solution Approach 1:
The patent pre-calculates and stores lookup tables that map random number outcomes to predetermined game results with specific volatility characteristics. Instead of repeatedly spinning and evaluating outcomes after the fact, the system pre-determines the mapping relationships between random numbers and game outcomes, allowing for direct retrieval of volatility-compliant results without iterative processing.
Solution Approach 2:
The patent introduces lookup tables as intermediary data structures between the random number generator and the game outcome determination. These lookup tables serve as a mediator that translates random numbers into pre-validated game outcomes that satisfy volatility criteria, eliminating the need for repeated evaluation cycles.
2Reliability
If repeated random re-spins are used to meet target volatility criteria, then the game outcome satisfies the target RTP and volatility thresholds, but the computational resources and processing load increase
Solution Approach 1:
The system pre-computes and stores lookup tables containing the mappings between random numbers and game outcomes that satisfy target volatility and RTP criteria. This preliminary computation eliminates the need for repeated computational evaluation cycles during actual game play, significantly reducing real-time computational resource consumption.
Solution Approach 2:
The patent creates simplified lookup table structures that copy and store the essential mapping relationships between random numbers and compliant game outcomes. These pre-generated tables serve as efficient substitutes for complex real-time evaluation algorithms, reducing computational complexity and resource requirements.
3Reliability
If multiple game outcomes are evaluated in the background, then a satisfying outcome is found, but the process becomes inefficient and time-consuming
Solution Approach 1:
The patent performs the evaluation of multiple potential outcomes in advance during system initialization or off-peak periods, storing the valid outcomes in lookup tables. This preliminary bulk evaluation eliminates the need for continuous background processing during game play, significantly improving evaluation efficiency while maintaining outcome validity.
Solution Approach 2:
Instead of systematically evaluating multiple outcomes one by one in the background, the patent uses pre-computed lookup tables to directly access valid outcomes, effectively skipping the iterative evaluation process and rushing through to the result immediately.
