Thiruvananthapuram : According to the police, several teenagers in the country as well as in the state are reportedly playing the deadly online game ‘Blue Whale Challenge’. The game is reportedly created by a former convict in Russia and is said to psychologically provoke players to indulge in daring, self-destructive tasks for 50 days before finally taking the ‘winning’ step of killing themselves - and each deadly task must be filmed and shared as ‘proof’. After completion of each task, the players are also asked to make cuts on their forearms, which eventually trace out the shape of a blue whale. The term blue whale comes from the phenomenon of beached whales, which is linked to suicide. The state police on warned the public to advise their teenagers and children to refrain from getting addicted to it. This was under the instructions of State Police Chief Loknath Behera who claimed that the game has affected not only children but also adults.
