Know Them All is a social club in Rotterdam that runs an English-language pub quiz designed for people who want to meet others. Participants arrive individually and are assigned to mixed teams on the night, making it easy to connect with new people while playing. The quiz consists of five rounds of general knowledge questions. The club holds its Know Them All English Pub Quiz every Thursday at 19:00. The format encourages conversation and teamwork among teammates as they answer questions together. The event is suitable for expats, newcomers, and locals interested in expanding their social circle.
