Envirobots is a mobile game developed during the Global Game Jam 2018 in which players are motivated to interact with each other to optimize their robot to their individual environment. To adapt to your environment you need to “pair” your robot with a different robot. This happens through QR-Code scanning. Your data is sent to the scanned person. Afterwards both of you get a new, better adjusted robot. The first player with a perfect adapted robot wins.
