Solution Overview

Problem

Conventional progressive jackpot systems fail to provide equal winning probabilities for players across different gaming stations offering wagering games with varying jackpot trigger probabilities, leading to unequal opportunities for winning major jackpots.

Innovation Solution

A progressive jackpot system that normalizes the winning probability for players across all gaming stations by assigning eligibility probabilities based on the jackpot trigger probabilities of individual games, ensuring that each player has an equal chance of winning the major progressive jackpot regardless of the game played.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple gaming stations administering different wagering games with different jackpot trigger probabilities are linked to a common progressive jackpot, then the progressive jackpot increases more quickly and adds appeal, but the winning probability becomes unequal across different gaming stations

Engineering Contradiction:
Improveprogressive jackpot accumulation rateVSAvoidequality of winning probability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system assigns different eligibility probabilities to different gaming stations based on their specific jackpot trigger probabilities. Each gaming station receives a customized eligibility probability that compensates for its underlying game's trigger probability, ensuring that players at all stations have equal overall chances of winning the progressive jackpot despite playing different games with different trigger characteristics.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts the eligibility probability parameter for each gaming station based on its jackpot trigger probability. By changing this parameter, the system equalizes the effective winning probability across all gaming stations while maintaining the ability to link diverse games with different trigger probabilities to the same progressive jackpot.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If gaming stations with different jackpot trigger probabilities are linked to the same progressive jackpot, then diversity of games is increased, but fairness of winning opportunities is compromised

Engineering Contradiction:
Improvegame diversityVSAvoidfairness of winning opportunities
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system applies local quality by customizing the eligibility probability for each gaming station according to its specific game characteristics and jackpot trigger probability. This allows the system to maintain game diversity while ensuring fairness, as each station receives tailored parameters that compensate for its unique probability characteristics.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system achieves equipotentiality by adjusting eligibility probabilities so that all gaming stations have equal effective winning potential despite having different underlying jackpot trigger probabilities. This creates a level playing field where players at any gaming station have the same overall chance of winning the progressive jackpot.

Inventive Principle:
Principle #12Equipotentiality

3Adaptability or versatility

If conventional progressive jackpot systems link gaming stations with different jackpot trigger probabilities, then the system can accommodate various game types, but the probability normalization becomes complex

Engineering Contradiction:
Improvecompatibility with different game typesVSAvoidprobability normalization mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system introduces an intermediary eligibility probability layer between the game-specific jackpot trigger probabilities and the progressive jackpot award mechanism. This intermediary parameter simplifies the normalization process by providing a uniform interface for all gaming stations while accounting for their different underlying probabilities through the eligibility probability adjustment.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Systems and methods of operating a major progressive jackpot linked to wagering games having different jackpot triggers with different probabilities. The major jackpot winning probabilities may be normalized such that players may have the substantially the same odds to win the major progressive jackpot regardless on the wagering game being played. During game play, the gaming stations may be randomly selected to participate for a chance to win the major progressive jackpot according to an eligibility probability, which may be inversely proportional to the probability of a jackpot trigger for the wagering game administered by the gaming station. Players may be informed of whether the current round of game play is eligible for the major progressive jackpot after wagers are placed and before the current round of game play.
