Game System Difficulty Adjustment via Reference Portion Distance

The patent applies local quality by making different reference portions have different distances from the player's position. Specifically, at least one reference portion is positioned at a distance different from the standard predetermined distance, creating local variation in the game space. This allows difficulty adjustment without uniformly increasing mark quantity, as players must adapt to varying distances and timing requirements for different reference portions.

The patent introduces a new dimension for difficulty adjustment by varying the distance parameter of reference portions from the player. Instead of only increasing the number of marks (one-dimensional approach), the system now adjusts difficulty by modifying spatial dimensions - specifically the distance between player position and reference portions. This creates varied movement paths and timing requirements while maintaining adequate visibility of each mark.

Rather than uniformly increasing the number of operation indication marks across the entire screen, the patent applies local quality by selectively positioning reference portions at varying distances. This creates difficulty variation through spatial arrangement rather than quantity increase, reducing screen clutter while maintaining challenge.

The patent changes the distance parameter of reference portions from the standard predetermined distance. By adjusting this spatial parameter, the system achieves difficulty modulation without adding more objects to the screen. The varied distances create different movement velocities and timing requirements, providing difficulty adjustment through parameter variation rather than object multiplication.

The patent maintains overall game structure stability by keeping most reference portions at the standard predetermined distance, ensuring consistent gameplay patterns. However, it introduces local quality variations by positioning at least one reference portion at a different distance, creating controlled deviations that enable difficulty adjustment without disrupting the fundamental game structure.

The patent introduces dynamics by making the distance parameter of reference portions variable rather than fixed. While the base structure maintains predetermined distances for stability, the system dynamically adjusts at least one reference portion's distance to modulate difficulty. This creates a flexible system that balances structural consistency with adaptability.
