Fastest-growing social network game

The follow-up to Zynga’s smash hits FarmVille (2009) and FrontierVille (2010) had a lot to live up to, but CityVille turned out to be even more successful than its predecessors. The urban-building game claimed a staggering 26 million players within 12 days of its launch. The game earned 290,000 users on its first day alone. After just a week, players had built 2.7 million homes, 500,000 bakeries and 5 million sections of road.
