Time-Range Connect-the-Dots (Basic Version)

Detailed Description: Includes 5 colors, each color corresponding to 3 endpoints (15 endpoints in total). The endpoints are densely distributed. A 2-minute 30-second time limit is set. Players must complete all connections within the time limit. Connections cannot cross. The shorter the completion time, the higher the score (maximum score 100 points). Failure to complete within the time limit results in failure, but players can retry. This improves reaction speed and stress tolerance.
