The blue rectangle can move up, down, left, or right, and its size allows it to collide with the balls. The objective is to catch as many balls as possible within the time limit. The environment is simple, consisting of a white background and gray walls.
The game can be played directly in the browser without the need to download or register. The colorful balls bounce around the screen, making the gameplay visually engaging. The challenge lies in timing the blue rectangle's movements to catch the balls before they disappear or collide with the walls.
