Create it once, share the code once — it never expires. Every round tagged to it goes in the group's history: who played, who shot what, who won, the running tally.
The others open Parley and tap Join with a code — or send them the link and it joins them automatically. Works with every game.
Give every group's round the same event name and they all roll into one leaderboard — different courses included. Your round code above never changes.
