So, at my school we have a set of around 9 or 10 handheld radios that we use to go out on campus and play a game on. We always play the same thing, which is radio hide and seek. Recently, we added the rule that whoever gets found becomes a seeker with the original seeker.
Frankly, this gets a bit repetitive at times, but it's still fun.
I wanted to know your ideas on games we can play with an entire high school campus and 10 handheld radios.
