The Blue Whale Game also known as "Blue Whale Challenge", is a 21st-century social network phenomenon that is claimed to exist in several countries, beginning in 2016. The game reportedly consists of a series of tasks assigned to players by administrators over a 50-day period, with the final challenge requiring the player to commit suicide.
There is still uncertainty over how a participant plays the game. While some say the user has to install some app on their smart phone, others say it’s via social media platforms such as Instagram and Facebook where the administrators get in touch with the participant after those interested throw out postings on social media asking for a “curator”. A number of different hashtags— #bluewhalechallenge, #curatorfindme, #i_am_whale — act as signals for the anonymous curators.
The horrifyingly dangerous game has been linked to at least 130 teen deaths across Russia and police in the UK have now started warning parents about the challenge.
