At the end of each interval, the organizer rings a bell, clinks a glass, or blows a whistle to signal the participants to move on to the next date.
At the end of the event participants submit to the organizers a list of who they would like to provide their contact information to.
Speed dating is a formalized matchmaking process which has the purpose of encouraging eligible singles to meet large numbers of new potential partners in a very short period of time.
On the other hand, a couple that decides they are incompatible early on will have to sit together for the duration of the round.
Most speed dating events match people at random, and participants will meet different "types" that they might not normally talk to in a club.
Online dating participants, in contrast, only find a compatible match with 1 in 100 or fewer of the profiles they study.
As reported by the BBC in the Science of Love, it only takes between 90 seconds to 4 minutes of face-to-face interaction to determine attraction, which gives speed dating an advantage over online dating.
