This week a 7th standard student in Madhya Pradesh also jumped off from the 3rd floor because of this challenge.
"He was on his way to complete a task in the challenge", said a police officer, noting that the boy appeared "lost" and was silent when he was found.
The 13-year-old boy had climbed the railing on the third floor of the Chameli Devi School in Indore's Rajendra Nagar area and attempted to jump, but alert classmates and a sports coach present there pulled him back.
The students informed their teachers, who approached the police.
Rupesh Kumar Dwivedi, Additional Superintendent of Police said in a statement, "Initial investigation suggests that the boy had been playing the Blue Whale game on his father's cellphone for the last couple of days".
On the 50th and last day, masters behind the game give players the final task of committing suicide by jumping off a terrace building while, again, documenting the act in the form of photos/video.
The alleged victim of the challenge - which is known as suicide game - has been sent for psychological counseling, police said. The online blue game has claimed the lives of around 150 people in Europe and Russian Federation so far.
The child was playing the game on his father's mobile phone for a long time, but the parents had no clue, say police.
Once you sign up for the game, which originated in Russian Federation, it will assign you daily tasks to complete for 50 days. Police told reporters that the boy tried committing suicide in order to complete the final stage of the dreaded Blue Whale Game.
The Blue Whale game originated around 2015 in Russian Federation and spread via social media.
Online games like the Blue Whale ask participants via social media to draw figures on a paper and then carve them on their bodies.
