Insaniquarium is a 2001 virtual pets simulator video game, developed by Flying Bear Entertainment and published by PopCap Games and MumboJumbo. Before PopCap Games's involvement, the game was a web-based Java game released in 2001.

The first real game on Facebook was "FarmVille," which was launched in 2009 by the game development company Zynga. It quickly became one of the most popular and widely played games on the platform, allowing users to build and manage their own virtual farms.
