The Home Department advisory, made in the wake of the suicide of a 19 year-old boy in Madurai who played the game, also warned internet users from sharing links, as it was "illegal" to do so and that they "will be punished as per law."
Citing available information, it said children in the age group of 12-19 years "are the most vulnerable group over the internet to be most prone to Blue Whale Challenge and similar games."
The advisory said the name was also available under other names like A Silent House, A Sea of Whales and Wake Me Up at 4:20 AM.
"Hence, both the parents and teachers are advised to observe the children's behavior closely to identify any unusual changes like moodiness, less or no communication, lack of interest in studies and falling grades, which may be an indication for the children to fall prey to these evil online games," it said.
Psychological counselling to the concerned child should also be provided through government hospitals/NGOs, it added.
"It is also informed to the general public and internet users to refrain from forwarding any online links related to this game and make someone vulnerable and any such act is illegal and will be punished as per the law."
"They are also advised not to forward any such viral messages originated without credible sources (while) discussing about this game," it added.
