What appears to have happened is that earlier this year, Riley Walz launched "Payphone Go" in California, which ended in March; Norris credits her own PayphoneGo was being inspired by Walz's game.
And maybe Payphone Tag was inspired by Walz, too? Hard to tell.
Payphone Go maps California's 2,203 remaining payphones and lets players earn points by finding and calling them.
