Timers run continuously from 20:00 to zero, then restart automatically. Join a waiting list by selecting all 4 names from the roster. The next waiting group takes the court when the round ends. Use Reset timer to start a fresh 20-minute round; this changes the timer for everyone without changing players or the waiting list. Coordinate with players on court before resetting. Names are publicly visible. Staff sign-in is only needed to manage players and groups.
