Solution Overview

Problem

Existing game machines allow players to predict game outcomes due to fixed symbol arrangements, reducing game excitement and interest.

Innovation Solution

A game machine with a lottery-based system where special symbol columns move and change symbols in cells upon meeting a bonus condition, incorporating a special symbol column lottery device, movement control device, and prize winning determination device to dynamically arrange symbols and determine winning patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If symbols are arranged in fixed positions in cells, then the game machine structure is simple, but players can predict game outcomes reducing excitement

Engineering Contradiction:
Improvesymbol arrangement structureVSAvoidgame excitement
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The patent implements dynamic symbol arrangement by introducing a special symbol column that moves horizontally across multiple cells, replacing symbols in each cell it passes through. This dynamic element transforms the static symbol arrangement into a changing configuration, making outcome prediction difficult while maintaining relatively simple device structure through programmed movement patterns.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The special symbol column operates in an additional horizontal dimension, moving across cells from left to right while regular symbols move vertically. This dimensional addition creates complex two-dimensional symbol interactions and arrangement patterns that prevent prediction while keeping the underlying mechanism manageable through structured movement rules.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of manufacture

If a special symbol column is introduced to change symbols dynamically, then game unpredictability increases, but device complexity increases

Engineering Contradiction:
Improvegame unpredictabilityVSAvoidsymbol column control system
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The symbol system is segmented into regular symbol columns and a special symbol column with distinct functions. The special symbol column is further segmented into multiple symbols that can be independently positioned and moved. This segmentation allows complex unpredictable behavior to emerge from simple, well-defined components with clear movement rules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The special symbol column acts as an intermediary element between the player's initial symbol arrangement and the final game outcome. It mediates the transformation by systematically replacing symbols according to predetermined movement patterns, adding unpredictability through its interaction with regular symbols while following structured control rules.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If special symbols replace regular symbols in cells, then winning pattern variety increases, but symbol management complexity increases

Engineering Contradiction:
Improvewinning pattern varietyVSAvoidsymbol replacement system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system changes the parameter of symbol identity by allowing special symbols to replace regular symbols in cells. Each special symbol carries specific properties (such as wild card functionality or special bonus triggers) that transform the characteristics of the cell it occupies. This parameter change enables diverse winning patterns while following systematic replacement rules that manage complexity.

Inventive Principle:
Principle #35Parameter changes

AI summary

A game machine uses a lottery region having cell columns and symbol columns for providing a game opportunity, causes a special symbol column to appear in it, determines by lottery symbols of the special symbol column, causes the special symbol column containing the symbols obtained by a lottery result to appear and moves and stops the special symbol column so that the symbols of the special symbol column are arranged on the cells to be changed, and determines whether the symbols arranged in a cell group of a determination target form a prize winning pattern based on the symbols arranged by the special symbol column. Further, the game machine moves the special symbol column along each cell so that at least a direction crossing a movement direction of each symbol column is included as a movement direction of the special symbol column.
