The Blue Whale Challenge, also called Blue Whale game, or simply Blue whale is an internet phenomenon that started in 2016, in Russia. Over a period of 50 days, participants are assigned tasks. Each participant gets one task a day. At first, the tasks are harmless (such as: get up at 4.30am, and watch a horror movie). Later, the tasks require the participants to hurt themselves. The final task requires the player to commit suicide.
