Listen to the teacher playing the crewmates rhythm (Teacher may use spacebar or click on the question on top of the page to play each rhythm) 4. If the rhythm performed by the teacher is correct the crewmate is not an imposter. If the rhythm performed by the teacher is incorrect (does not match what you see) you found the imposter. 5. Every 4 rhythms or so, the teacher calls an "Emergency Meeting" At that time the teacher chooses students to accuse crewmates of being an imposer/imposters. 6. Play until all imposers are found (2-3 imposers work well in this game)
