Use iPhone Mirroring to Play iPhone Games
Granted, this will depend on the type of games you play. If you play games like Brawl Starts on your iPhone, they might not work as well on your Mac.
But if you have slower-paced games like Papers, Please, or A Dark Room, you can play them on your Mac with the help of iPhone Mirroring.
Again, it’s not as intuitive as playing on your iPhone, but if you don’t have anything else to do at work and don’t want to be too obvious, this is a good way to pass the time.
