The mouse is used for clicking on panels and interacting in the game
Grow Nano Vol 3 is another fun-addicting Hooda Math game where you will help a little boy cure his sickness. The game features some panels that can help you heal him. Your main mission is to click on the panels orderly, level them up and be sure that the boy will become stronger again. Whenever you click the panels, they will grow and have influences on each other. Your game will be restarted when all levels of the panels are maxed out. Wish you luck!
