Solution Overview

Problem

Existing gaming systems do not accurately reflect a player's level of gameplay over time in bonus game awards, as they only consider the last wager amount and not the varying wager amounts placed during a gaming session, leading to an inconsistent and unfair distribution of bonus game awards.

Innovation Solution

A gaming system that maintains a database of bonus game attributes, where each attribute is associated with a different wager amount, and modifies the probabilities of selecting these attributes based on the player's wager history, ensuring that the average expected payout for a bonus game is proportional to the total average wager amount placed since the last play.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the gaming system increases bonus game awards in proportion to the last wager amount, then players who wager more receive greater bonuses, but the system does not accurately reflect the player's overall gameplay history and wagering patterns

Engineering Contradiction:
Improveaccuracy of bonus award reflectionVSAvoidwager history information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary actions by maintaining a database of bonus game attributes and continuously updating it with each wager placed. Before determining the bonus award, the system has already accumulated and processed the player's wagering history, allowing it to accurately reflect overall gameplay patterns rather than just the last wager amount.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring and recording each wager placed by the player, updating the database of bonus game attributes accordingly. This feedback loop ensures that the bonus award determination is based on the complete wagering history, accurately reflecting the player's gameplay patterns and wagering behavior over time.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the gaming system uses a fixed bonus game award structure, then the system is simple to operate, but it does not provide fair or consistent bonus awards across varying wager amounts

Engineering Contradiction:
Improvebonus award consistencyVSAvoidbonus game attribute database
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system transitions from a static, fixed bonus award structure to a dynamic one where bonus game attributes are continuously updated based on player wagering. The database adapts in real-time to reflect the player's wagering patterns, ensuring fair and consistent bonus awards that scale appropriately with varying wager amounts while maintaining operational simplicity through automated processes.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If the gaming system modifies bonus game attributes based on each wager placed, then the average expected payout accurately reflects total average wager amount, but the system complexity increases

Engineering Contradiction:
Improvepayout proportionalityVSAvoidprobability modification system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system modifies parameters by dynamically adjusting the probabilities associated with different bonus game attributes based on the player's wagering history. Each wager placed triggers an update to the database, changing the parameters that determine bonus awards. This ensures the average expected payout is precisely proportional to the total average wager amount while managing complexity through systematic parameter adjustment.

Inventive Principle:
Principle #35Parameter changes

AI summary

The gaming system disclosed herein accounts for game play over a gaming session in determining a bonus game attribute for a triggered bonus game. The gaming system maintains a plurality of different bonus game attributes. Each different bonus game attribute is associated with a different bonus game attribute modification event and an initial probability of that bonus game attribute being selected for a play of a bonus game. For each bonus game attribute modification event that occurs, the gaming system modifies the probability that the associated bonus game attribute will be selected for a play of a bonus game. Upon an occurrence of a bonus game triggering event, the gaming system randomly selects one of the maintained bonus game attributes. The gaming system then displays a bonus game and determines a bonus game award utilizing the selected bonus game attribute.
