Rooms make World Guesser social; social adds noise. The best groups develop tiny habits: one person calls out language, another tracks vegetation, someone else refuses to speak during the first pass of a clip. You do not need military discipline, just agreed pauses.
Helping without backseating
A hint framed as a question lands softer: ‘Do you see diacritics?’ beats ‘It’s obviously Vietnam.’ The second line ages poorly when you are wrong and rude.
Celebrate smart losses
When a friend pins intelligently and still misses, that round taught the room something. The staff keeps score; we also keep respect. The game lasts longer that way.
