Superpoke! and SuperPoke! Pets were virtual goods apps for Facebook and MySpace originally created by Nikil Gandhy, Will Liu, and Jonathan Hsu. They launched less than one month after the creation of the Facebook Platform. Max Levchin's Slide acquired the application and its creators in 2007, with the application growing to become one of Facebook's most popular applications in terms of monthly active users. The application mimicked Facebook's own " poke" feature, adding new actions like smiles, winks, slaps, and “smacking” Facebook friends. At one point SuperPoke! allowed users to virtually “stab” friends; Facebook later asked Slide to remove this option.
SuperPoke! differentiated itself from other applications by introducing characters such as a sheep, chicken and penguin. These characters were originally designed by Nikil Gandhy. Superpoke! was shut down on September 27, 2011 and SuperPoke! Pets closed March 7, 2012
