A group of bubbles moves through the air towards the royal castle. They contain a poisonous gas that is capable of destroying all living things. You will need to destroy them all in Bloon Pop. Several rows of balls will be visible on the screen in front of you. They will all have a specific color. At a certain distance, your crossbow will be loaded with an arrow. You will have to click on it to bring up a dotted line. With its help, you will calculate the trajectory of the shot and make it. If your sight is accurate, then the arrow, having flown a certain distance, will hit the balls. They will burst and you will receive points. Thus, you will clear the playing field of balls.
