Multi-Area Separation Connection

Detailed Description: The screen is divided into 4 independent areas (top, bottom, left, right), each corresponding to a color (red, yellow, blue, green). Each area has 4 endpoints. Players must connect endpoints of the same color within the same area, ensuring the lines do not cross area boundaries or intersect. A 3-minute time limit is set. Upon completion, each area will be filled with the corresponding color, forming a complete four-color partition pattern, improving area planning skills.
