InMind takes you on a roller coaster ride through someone's brain who has cancer. You are tasked with identifying the "disordered" neurons and focusing your laser beam on them in order to destroy and neutralize the cancerious neurons. We love this game because it has incredible graphics and realistic depiction of what it's like to travel through the neural pathways of the brain as though you were shrunk to the size of a red blood cell. One of the best educational games for mobile VR of all time! Free on Google Play and the App Store.
