Solution Overview

Problem

In social games, when players find it difficult to achieve predetermined conditions, the continuation rate of players decreases, leading to a decline in game operation sustainability.

Innovation Solution

An information processing device and game program that execute random determination processes to rearrange symbols in specific payout patterns within a predetermined period, ensuring that a specific payout is awarded regardless of the initial random determination result, thereby lowering the difficulty level and improving player continuation rates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the winning probability of a specific arrangement pattern is improved, then the difficulty level of clearing the condition is lowered, but the construction of the control program becomes complicated

Engineering Contradiction:
Improvewinning probabilityVSAvoidcontrol program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary random determination at the start of a quest to secure a winning arrangement pattern, then executes that predetermined pattern during gameplay. This advance preparation allows the system to guarantee a win without complex real-time control logic, as the outcome is already decided beforehand.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The game process is divided into distinct phases: a preliminary random determination phase at quest start, and a separate execution phase during gameplay. By separating the determination of the winning pattern from the gameplay itself, the system avoids the need for complex real-time control while ensuring the predetermined win occurs.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the winning probability of a specific arrangement pattern is improved, then the player continuation rate is improved, but the control program construction becomes complicated

Engineering Contradiction:

Solution Approach 1:

The system performs preliminary random determination at the start of a quest to secure a winning arrangement pattern, then executes that predetermined pattern during gameplay. This advance preparation allows the system to guarantee a win without complex real-time control logic, as the outcome is already decided beforehand.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If only the winning probability of a specific arrangement pattern is improved, then the difficulty level is lowered, but the control program construction becomes complicated due to multiple prizes

Engineering Contradiction:
Improvedifficulty levelVSAvoidcontrol program complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system applies a special mechanism only to the specific arrangement pattern associated with the target quest, while leaving other arrangement patterns and their payouts unchanged. This localized approach allows the system to improve the difficulty balance for specific quests without requiring complex global control logic that would affect all game elements.

Inventive Principle:
Principle #3Local quality

AI summary

The present invention provides an information processing device and a program that can lower a difficulty level of clearing a predetermined condition and improve a continuation rate of a player.The information processing device is configured to execute a game in which symbol random determination for determining symbols to be rearranged is executed, and when an arrangement pattern of the determined symbols corresponds to one of a plurality of kinds of preset arrangement patterns, a payout corresponding to the arrangement pattern is awarded, and the information processing device includes a controller programmed to execute a) a process of executing random determination as to whether to rearrange the symbols in an arrangement pattern corresponding to a specific payout among the payout, and b) a process of rearranging the symbols in the arrangement pattern corresponding to the specific payout and awarding the specific payout within a predetermined period of time regardless of whether the symbol random determination is executed, when a random determination result in the process a) wins a prize.
