Solution Overview

Problem

Gaming machines face limitations in offering novel and stimulating variations while adhering to regulatory restrictions, as they typically allow only a single special symbol to occupy adjacent positions on reels, limiting the potential for winning combinations and player engagement.

Innovation Solution

A gaming machine and method that display a grid of symbol cells, where a controller initiates a game by detecting a trigger condition, selects a set of symbols, and replaces symbols in adjacent positions on reel strips to establish a predetermined combination, increasing the probability of winning by allowing multiple special symbols to appear consecutively and dynamically altering reel content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If only a single special symbol is allowed to occupy adjacent positions on reels, then the machine complies with traditional gaming regulations, but the variety of winning combinations and player engagement is limited

Engineering Contradiction:
Improvevariety of winning combinationsVSAvoidgaming machine configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The reel strip is made dynamically reconfigurable during gameplay. The controller can alter the sequence of symbols on the reel strip in real-time, allowing multiple special symbols to appear in adjacent positions when beneficial to the player, while maintaining compliance with regulatory requirements through controlled dynamic changes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system pre-determines beneficial symbol combinations and prepares the reel strip configuration in advance before the spin. By analyzing the initial symbol distribution and predicting advantageous outcomes, the controller pre-arranges the reel strip to enable multiple special symbols to appear consecutively, ensuring regulatory compliance while enhancing winning opportunities.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the reel strip sequence is fixed, then the machine is simpler to manufacture and regulate, but the probability of winning combinations is reduced

Engineering Contradiction:
Improveprobability of winningVSAvoidreel strip configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The reel strip transitions from a static, fixed sequence to a dynamic, reconfigurable sequence. The controller modifies the symbol arrangement on the reel strip between spins or during bonus rounds, enabling multiple special symbols to appear in advantageous positions, thereby increasing winning probability while managing complexity through software control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of symbol sequence arrangement on the reel strip. By dynamically adjusting which symbols appear in which positions based on predetermined algorithms and player status, the machine optimizes the probability of winning combinations without requiring physical reconfiguration of the reel strip hardware.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple special symbols appear consecutively on the reel strip, then player engagement and winning probability increase, but regulatory compliance becomes more difficult

Engineering Contradiction:
Improvegameplay variationVSAvoidregulatory compliance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary analysis of the reel strip configuration before the spin occurs. By pre-determining whether multiple special symbols should appear consecutively based on regulatory parameters and game state, the controller ensures that such configurations are only activated when they comply with jurisdictional requirements, thus maintaining reliability while enabling gameplay variation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The controller continuously monitors the reel strip configuration and spin outcomes to ensure regulatory compliance. When multiple special symbols are about to appear consecutively, the system checks against predetermined regulatory constraints and adjusts the configuration if necessary, providing real-time feedback control that balances gameplay variation with compliance reliability.

Inventive Principle:
Principle #23Feedback

AI summary

The game machine comprising a display and a controller is provided. The display is configured to display a plurality of symbol cells displayed in a grid. The grid defines a plurality of columns, each with an associated reel, an associated reel strip, a plurality of symbol positions, and each symbol position populated by a game symbol. The controller is configured to initiate a game and detect a trigger condition. In response the trigger condition the control then establishes a number of symbols in a set of symbols, selects a set of symbols based on the established number of symbols, with the set of symbols including a plurality of game symbols, and replaces each of the symbols in a plurality of symbol positions on at least one of the reel strips with the selected set of symbols. The controller then establishes a predetermined combination of symbols within the grid.
