Today in the new exciting online game Need Light you will turn on the light in a dark room. In front of you on the screen you will see a room in the upper part of which there will be a wire with a hemisphere sliding to the left. Under this structure you will see a tunnel through which a white ball will move at a certain speed. You will need to guess the moment when the hemisphere will be above the ball and click on the screen with the mouse. The wire will go down and the hemisphere will touch the ball. This way you will get light and get points for it in the Need Light game.
