Your invite code
Install Tangler, then enter this code to join the crew. Universal links don't survive an app install, so hang on to it.
On iPhone, get Tangler from TestFlight. TestFlight will ask you to sign in with your Apple ID and password, because Tangler is a private beta. Don't enter your invite code there; it goes into the Tangler app once it's installed.
Tangler is a sports game, currently in closed testing.
