Before you on the screen you will see a playing field on which there will be two planks. A ball will hang between them in space. You will have to click on it with your mouse. Thus, you will call a special arrow with which you can set the strength and trajectory of the ball. When ready, you will make your move. You will need to make sure that the ball touches both bars. Once this happens, you will receive points and proceed to the next level of the game.
