Try to grow the line graph to reach as many red dots as possible Each red dot reached increases your score. Line growth is directed by configuring the yellow dots where growth splits occur. Once the yellow dots are configured to your liking, start growing the line by left-clicking on the green dot. Difficulty increases as level increases. To delete a yellow dot arrow, rotate it all the way around. Each yellow dot will need 2 arrows attached (there are some that require 3).
