An indoor sports hall in Sofia, Bulgaria, is depicted, featuring a multi-sport court with a dominant blue synthetic surface bordered by an orange section in the foreground. White lines delineate various playing areas. The hall's walls are constructed of light brown brick, with a dark horizontal trim line running along their lower portion. Large, multi-pane windows, secured with an internal grid or mesh, are visible high on the far wall. The ceiling is equipped with multiple rectangular fluorescent light fixtures providing illumination. Approximately ten adult males are present on the court, engaged in a sports activity. Most are wearing athletic attire including t-shirts and shorts in various colors (blue, yellow, green, black). A central figure, wearing a blue shirt and dark shorts, holds a spherical ball, consistent with a basketball or handball, appearing to dribble or prepare for a pass. Other participants are distributed across the court, some also holding similar balls, suggesting a practice or informal game. A goal frame with a net, suitable for handball or futsal, is visible on the far right side of the court. In the immediate foreground, on the right, a person's hands are shown holding an active black smartphone, wearing a dark jacket sleeve and partially visible sneakers. This individual is observing the activity on the court.
