The Blue Whale Challenge is an online "game" where players are given tasks over 50 days by administrators, with the final task being suicide. It originated in Russia in 2013 and has since caused over 150 deaths globally. In India, several teenage deaths have been linked to the game since July 2017. Signs of playing include loneliness, social media addiction, and self-harm. Parents are encouraged to monitor children's online activity and watch for signs of distress. Other dangerous online games that encourage self-harm include the Ice and Salt Challenge and Choking Game.
