Having been on the market for just over a month, Zynga's latest Facebook title CityVille has already attracted an astonishing 84.2m players.
Inside Social Games reports that this puts CityVille ahead of Facebook's current record-holder, Zynga's FarmVille. The latter title, however, took nine months to reach that landmark, suggesting CityVille still has a long way to go.
it currently boasts around 16.8m active users every day. By contrast, at its peak FarmVille enjoyed around 34.5m daily users.
