Solution Overview

Problem

Current gaming systems often skew participation and award distribution in group events, as players tend to maintain minimum wager levels to remain active, leading to an imbalance in the probability of participation based on their actual level of play.

Innovation Solution

A gaming system with a central server that monitors wagers across multiple machines, determining when a bonus event occurs and selects machines to provide awards based on relative wager activity, ensuring that active players with higher wager amounts have a higher probability of participating or winning, while those with lower wager amounts have a lower probability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If players maintain minimum wager levels to remain active in group events, then all players can participate in bonus events, but the probability of participation becomes skewed and does not reflect actual level of play

Engineering Contradiction:
Improveparticipation eligibilityVSAvoidparticipation probability accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system changes the parameter of participation probability from a fixed equal chance for all active players to a variable chance based on wager amount. The controller assigns different probabilities to different players based on their wager levels, transforming the uniform participation model into a differentiated one that reflects actual play levels.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the system provides equal participation opportunities to all active players, then inclusivity is improved, but fairness relative to wager amount deteriorates

Engineering Contradiction:
Improveparticipation accessibilityVSAvoidaward distribution fairness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system applies local quality by giving different participation probabilities to different players based on their individual wager amounts. Instead of a uniform approach, each player receives a participation probability tailored to their specific wager level, creating localized fairness that accounts for individual contribution levels.

Inventive Principle:
Principle #3Local quality

3Reliability

If the system uses a central server to monitor wagers and determine bonus events, then award distribution control is improved, but system complexity increases

Engineering Contradiction:
Improvebonus event managementVSAvoidsystem architecture
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The controller serves as an intermediary between the players and the bonus award system. It monitors wager amounts, determines when bonus events should occur, and assigns participation probabilities based on wager data. This intermediary manages the complexity of coordinating multiple players and machines while maintaining fair and reliable bonus event distribution.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A gaming system including a central server linked to a plurality of gaming machines, gaming tables, hand held gaming devices and/or community gaming displays. The central server monitors wagers placed on any games played. Based at least in part on the wagers placed, the central server determines when one or more bonus events will occur and which players to provide any bonus awards.
