Solution Overview

Problem

Conventional slot machines lack the ability to dynamically adjust payout amounts based on player interaction and symbol rearrangement, leading to a lack of engagement and variability in gameplay experience.

Innovation Solution

A slot machine system that allows players to select specific symbols during a subgame, with a controller varying payout amounts based on the number of selected symbols rearranged during a predetermined number of special game iterations, increasing payout amounts as the number of rearranged symbols increases or setting a minimum payout when no awards occur.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional slot machines use fixed payout rates determined in advance, then the payout structure is simple and easy to understand, but the gameplay lacks engagement and variability

Engineering Contradiction:
Improvepayout variabilityVSAvoidpayout structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The payout amount is dynamically adjusted during the special game based on the cumulative count of specific symbols rearranged. The controller varies the payout amount in accordance with this count, transforming the static payout structure into a dynamic one that adapts to player performance and increases engagement.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the slot machine varies payout amounts based on symbol rearrangement count, then player engagement increases, but the game complexity increases

Engineering Contradiction:
Improveinteractive gameplayVSAvoidcontrol mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The controller counts the cumulative number of specific symbols rearranged during the special game and uses this count as feedback to determine the payout amount. This feedback mechanism creates a direct link between player action and reward, enhancing interactivity while maintaining clear cause-and-effect relationships.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system establishes a predetermined number of special games to be executed and pre-defines the relationship between symbol count and payout amounts. This preliminary setup simplifies the control mechanism by having the rules determined in advance, reducing real-time decision complexity.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the slot machine executes multiple special games with varying payouts, then entertainment value increases, but the game duration increases

Engineering Contradiction:
Improvegame varietyVSAvoidgame time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The slot machine executes a predetermined number of special games in sequence, creating a periodic structure to the gameplay. This periodic action provides variety through multiple game iterations while maintaining a defined time boundary, preventing excessive game duration.

Inventive Principle:
Principle #19Periodic action

AI summary

When a start condition of a special game is established during a base game, payout amount of credits for occurrence of an award accompanied by payout of credits due to a specific symbol during a predetermined number of times of a special game is varied in accordance with the number of rearranged specific player-selected symbols at the start of the special game. Alternatively, payout amount of credits when the predetermined number of times of the special game terminate is varied in accordance with the number of times of occurrence of the award accompanied by payout of credits due to the specific symbol.
