Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing keno games lack features that enhance player engagement and increase the chances of matching spots, leading to reduced player interest and potential for higher awards.

Innovation Solution

The introduction of additional spots that are duplicates of player-selected spots, allowing for increased matching opportunities and introducing unique features based on duplicate draws, such as multipliers or free games, to enhance gameplay and award potential.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional keno games are played with a fixed pool of spots, then the game rules are simple, but player engagement and matching opportunities are limited

Engineering Contradiction:

Improvematching opportunitiesVSAvoidgame rules

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pool of spots is made dynamic by adding duplicate spots based on player selections. The system adapts the game pool in real-time during each play, transforming the static traditional keno pool into a dynamic structure that responds to player choices, thereby increasing matching opportunities without permanently complicating the game structure

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Duplicate spots are added to the pool in advance based on player selections before the drawing process begins. This preliminary action of expanding the pool with relevant duplicates ensures that players have increased matching opportunities from the start, while the complexity is managed by performing this expansion beforehand rather than during the game

Inventive Principle:

Principle #10Preliminary action

2Productivity

If additional duplicate spots are added to the pool, then the average expected payback percentage increases, but the game structure becomes more complex

Engineering Contradiction:

Improveaverage expected payback percentageVSAvoidpool structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Instead of uniformly expanding the entire spot pool, duplicate spots are selectively added only for spots that players have chosen. This local quality approach ensures that the pool expansion is concentrated in areas of player interest, increasing the probability of matches and thus the expected payback, while limiting the overall increase in pool complexity to only the necessary duplicates

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If duplicate spots are drawn, then unique features such as multipliers or free games can be triggered, but the drawing process becomes more complex

Engineering Contradiction:

Improveadditional featuresVSAvoiddrawing process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms where drawing a duplicate spot triggers specific additional features such as multipliers or free games. This feedback loop creates engaging gameplay moments and increases player engagement, while the complexity of the drawing process is managed by having predetermined feature triggers associated with duplicate draws rather than requiring complex real-time decision-making

Inventive Principle:

Principle #23Feedback

AI summary

Gaming systems and methods that provide a play of a keno game having one or more additional spots added to the pool of spots to be drawn from and that are based on the player selected spots, where duplicate drawn spots result in features other than matches of the player spots.
