Solution Overview

Problem

Conventional free spin games in slot machines lack excitement and fail to meet player expectations for higher prize probabilities, as they do not provide sufficient variety in symbol arrangements on the reels, leading to a lack of engagement.

Innovation Solution

A gaming machine with a processor that selects and displays a fixed symbol on specific cells or pay lines during the free spin game, allowing players to feel more involved in the game by selecting cells or lines, and varying the number of cells or lines displaying the symbol to enhance game variety and expectation of winning combinations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional free spin game is performed with random symbol arrangements, then the game structure is simple, but player excitement and engagement are insufficient

Engineering Contradiction:
Improvegame varietyVSAvoidgame structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The processor pre-selects specific cells on the reel before the free spin game begins and determines which symbols will be displayed in those cells. This preliminary action creates a controlled arrangement of guaranteed symbols that players can anticipate, enhancing excitement while maintaining a manageable game structure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of applying the same random symbol arrangement to all cells, the invention applies different symbol display rules to different regions: selected cells display predetermined symbols while non-selected cells display random symbols. This local differentiation creates variety and player engagement without overwhelming system complexity.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If fixed symbols are displayed on selected cells, then player expectation and engagement increase, but the game control complexity increases

Engineering Contradiction:
Improveplayer involvementVSAvoidcell selection control
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically performs cell selection and symbol assignment without requiring complex manual configuration. The processor autonomously determines which cells to select and what symbols to display, reducing the operational burden on players while maintaining high engagement through the visual presentation of fixed symbols in selected cells.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the number of selected cells varies during the game, then game variety and player excitement increase, but the prediction difficulty and game complexity increase

Engineering Contradiction:
Improvegame varietyVSAvoidsymbol arrangement prediction
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The number of selected cells is made dynamic, changing at different stages of the free spin game. The processor adjusts which cells are selected and how many symbols are fixed based on game progression, creating varying levels of player excitement and anticipation while maintaining controllable game complexity through programmed selection criteria.

Inventive Principle:
Principle #15Dynamics
