I copied and pasted this from Matte but uh Well, the Blue Whale challenge is about unknown people messaging other people "Do you wanna play?". If the person/victim responds or says yes, the game automatically begins. The unknown people(they have a Mickey mouse pfp and their names have "Jonathan Galindo" in it) gives you 50 tasks. 1 task each day. The task sounds easy at first. But, the longer you play, the worst it gets. The tasks gets darker and harder.. Example: carve a whale on your arm, stand at the edge of the bridge, cut your lip, kill an animal, etc. And the final/50th task is to commit suicide, if you don't wanna do it's they'll come find you and kill your family..!!

It’s a game that ends in death

Idk that much but I think it's a game that makes you harm yourself or something and you get threatened if you don't do it idk
