Solution Overview

Problem

Existing game systems in reward games, such as slot machines, lack variability and excitement, leading to player boredom due to unchangeable operation methods and a lack of expectation and surprise.

Innovation Solution

A game system and operation method that includes a game result generating unit and control unit to create rolling and stopping rollers with adjacent game symbols, allowing for consecutive free games and the potential overlap of special symbols across game rounds, enhancing visual effects and player engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operation method in reward games is kept unchanged, then the game rules are simple and easy to understand, but the player becomes bored easily and there is no expectation or surprise

Engineering Contradiction:
Improvesimplicity of game rulesVSAvoidvariability of game experience
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the game system adaptable during free games. The control unit dynamically adjusts the game behavior based on detected special symbols, allowing rollers to remain stationary or rotate, and enabling re-spins. This dynamic adaptation maintains simple base rules while adding variability through conditional modifications, resolving the contradiction between operational simplicity and experience variability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes game parameters during free games based on special symbol detection. When special symbols are detected, the system changes parameters such as roller rotation state, game continuation conditions, and payout calculations. This parameter-based adaptability allows the game to maintain simplicity while providing varied experiences through conditional parameter modifications.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If special symbols are kept stationary during free games, then the payout calculation is simple, but the visual effect and player engagement are reduced

Engineering Contradiction:
Improvepayout calculation complexityVSAvoidvisual effect intensity
Core Design Contradiction:
Device complexityVSIllumination intensity

Solution Approach 1:

The patent makes the roller behavior dynamic rather than static. Rollers can remain stationary or rotate based on game conditions and special symbol detection. This dynamic approach enhances visual engagement while the control unit manages calculation complexity by implementing clear rules for when rollers should rotate versus remain stationary, resolving the contradiction between visual effect and calculation simplicity.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the game provides fixed free games without additional options, then the game flow is straightforward, but the player lacks expectation and surprise

Engineering Contradiction:
Improvegame flow efficiencyVSAvoidgame option variability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements feedback mechanisms where the detection of special symbols during free games triggers additional game options such as re-spins or extended free games. This feedback loop maintains straightforward game flow by using clear detection rules while adding variability through conditionally triggered options, resolving the contradiction between flow efficiency and option variability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent uses preliminary detection of special symbols to determine subsequent game actions. By detecting special symbols during free games and pre-determining whether to offer re-spins or extensions, the system maintains efficient game flow while adding expectation and surprise through pre-planned conditional options.

Inventive Principle:
Principle #10Preliminary action

AI summary

When a control unit in a game system of the present invention stops rollers of a next free game from rolling during performing a plurality of consecutive free games, a special symbol appearing in a free game currently performed overlaps a game symbol appearing in the free game performed next. Accordingly, players can not only feel the fun of accumulating the special symbols and look forward to collecting more of the special symbols, but also make a probability of the special symbols appearing in a game screen of each of the free games to be kept constant, thereby simplifying the difficulty in calculating a return to player (RTP).
