Solution Overview

Problem

Existing gaming systems lack engaging bonus activities that provide an exciting, visually appealing experience without requiring complex player interactions or a predetermined end, and often fail to maintain player interest through random and theoretically infinite gameplay.

Innovation Solution

A gaming system featuring a display grid with roaming wild symbols that move randomly until reaching termination positions, allowing for continuous gameplay and dynamic award determination based on the symbols present at non-occupied grid positions, with movement rules controlling the odds and probability of game duration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If traditional bonus activities are used with predetermined end conditions, then the bonus activity has a clear termination point, but player engagement and excitement are reduced due to lack of continuity

Engineering Contradiction:
Improvebonus activity durationVSAvoidplayer interaction complexity
Core Design Contradiction:
Duration of action of moving objectVSEase of operation

Solution Approach 1:

The bonus activity transitions from a static, predetermined-end structure to a dynamic, continuously evolving game state. Wild symbols move randomly across the grid between spins, creating ever-changing patterns that prevent player boredom and maintain excitement without requiring complex player decisions or predetermined termination conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bonus activity eliminates natural termination points by implementing continuous wild symbol movement between spins. The grid positions are constantly rearranged through random wild repositioning, ensuring the game state never repeats and providing theoretically infinite gameplay duration while maintaining player engagement through persistent randomness and surprise.

Inventive Principle:
Principle #20Continuity of useful action

2Ease of operation

If bonus activities require complex player interactions, then players feel more involved, but player interest decreases due to the complexity of figuring out optimal play strategies

Engineering Contradiction:
Improveplayer interaction simplicityVSAvoidplayer engagement level
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The bonus activity operates autonomously without requiring player strategy or decision-making. The wild symbols self-arrange and self-move according to predetermined random rules, generating their own patterns and payouts. Players simply observe and react to the automatically generated game states, eliminating the need to figure out optimal play strategies while maintaining high engagement through pure randomness and surprise.

Inventive Principle:
Principle #25Self-service

3Device complexity

If bonus activities have predetermined end conditions, then the game structure is simple, but player excitement is reduced due to the inevitability of termination

Engineering Contradiction:
Improvebonus activity structureVSAvoidplayer interest maintenance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The bonus activity structure transitions from a static, predetermined-end design to a dynamic, continuously evolving system. Wild symbols randomly reposition themselves between spins, creating ever-changing patterns that prevent player boredom and maintain excitement without requiring complex player decisions or predetermined termination conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bonus activity eliminates natural termination points by implementing continuous wild symbol movement between spins. The grid positions are constantly rearranged through random wild repositioning, ensuring the game state never repeats and providing theoretically infinite gameplay duration while maintaining player engagement through persistent randomness and surprise.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A display grid includes a plurality of grid positions that are presented to a game player. One or more grid positions of the plurality of grid positions are defined as termination positions. One or more wild symbols are moved to grid positions proximate the grid positions associated with the one or more wild symbols using a random process. Winning results are determined using a pay table, based on both the one or more wild symbols and the symbols presented at the grid positions not associated with the one or more wild symbols after a spin. Random movement of the one or more wild symbols to grid positions proximate the grid positions associated with the one or more wild symbols is repeated until the one or more (or all) wild symbols move to the termination positions.
