Family Feud

Family Feud on mobile phones is an online only game played via a fast
paced, massively single player mechanic where the game never stops, users just
join in and leave at will.

Each round contains three normal questions and a Fast Money set of questions.
This implies that you might join in the middle of a round, but as rounds are
short and each question is only up for 30 seconds, it’s not long before there
is a new question ro a leaderboard to view. Between questions and at the end
of a round, the top 20 players are displayed. Players are scored on accuracy
and time. For every second that you delay in answering your total possible
score lowers.

What is interesting about this version of the game is that it became an ad-hoc
social network where users would sign in with various online names in order to
make new friends and share pictures.
