Unconfirmed Russian media reports link the deaths of two young women with the Blue Whale Challenge.
The name of this game seems to refer to the behavior of a number of blue whales who accidentally slapped themselves to shore and died.
There is no concrete evidence that this game has reached Indonesia, nor that this game really exists.
The Secure Internet Center in Bulgaria told Balkan Insight that the game is likely to be a rumor spread online, as there is no concrete evidence to suggest the challenge exists.
