Solution Overview

Problem

Existing slot machine bonus rounds lack variety due to fixed lengths and limited prize options, failing to provide an engaging player selection experience.

Innovation Solution

A slot game that includes a secondary game with selectable symbols on a touchscreen display, allowing players to pick symbols until all are selected, with options to reveal awards, award enhancers, or additional symbols, and incorporating a 'pick increase' feature to add more selections and a 'pick decrease' feature to remove choices without rewards, dynamically varying the game length and prize distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed number of selectable symbols are provided in the bonus round, then the game structure is simple and easy to operate, but the game lacks variety and player engagement

Engineering Contradiction:
Improvegame varietyVSAvoidgame structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bonus round dynamically adjusts the number of selectable symbols during gameplay. The system transitions from a static fixed-number selection to a dynamic structure where additional symbols can be added or removed based on player choices and game events, resolving the contradiction between simplicity and variety

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of selectable symbol count from a fixed value to a variable that can increase or decrease during the bonus round. This allows the game to adapt its complexity and variety dynamically while maintaining a relatively simple base structure

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the bonus round allows unlimited selections, then player engagement increases, but the game duration becomes unmanageable and loses structure

Engineering Contradiction:
Improveplayer engagementVSAvoidgame duration
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

The system implements feedback mechanisms where player selections trigger game events that can add or remove selectable symbols. This feedback loop creates dynamic adjustments to game duration based on player engagement, preventing both premature endings and excessive length

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The bonus round uses dynamic adjustment of the selection pool size based on gameplay progression. The system can expand the number of selections to maintain engagement or contract it to maintain structure, resolving the contradiction between engagement and duration

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the bonus round provides only fixed prize options, then the game is easy to understand, but player excitement and replay value decrease

Engineering Contradiction:
Improveprize varietyVSAvoidgame understanding
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The prize structure is segmented into multiple categories and tiers with varying values and characteristics. This segmentation allows for greater prize variety while maintaining clear, understandable categories that players can easily comprehend

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system varies prize parameters such as value, type, and availability during the bonus round. Different symbols can offer different prize characteristics, creating variety while maintaining a straightforward selection mechanism

Inventive Principle:
Principle #35Parameter changes

AI summary

A slot game includes a secondary game which upon being triggered displays an initial set of selectable symbols arranged on a touchscreen display at the gaming device, the player being provided ability to make selections from the selectable symbols until all selectable symbols have been selected, each selectable symbol corresponding to an associated benefit which is one of an award, an award enhancer, or one or more additional selectable symbols. If an option is picked revealing additional selectable symbols, the game adds more picks having associated benefit like those of the initial set and the player keeps selecting. The game may also have a “game pick” in which it removes one or more of the remaining unselected choices without awarding an associated benefit.
