The host picks how many spies are hidden in the room and how long the discussion lasts.
Every resident sees the same secret location; spies only know they're spies.
When the game starts, a timer runs while everyone talks and tries to spot the spies.
When the timer ends, everyone votes for who they think is a spy.
Voting has its own 30-second clock — if it's not decided in time, the spies win automatically.
Residents win if every spy is caught; spies win if even one stays hidden.
