One of the most infamous video games in history, Flappy Bird, is back. Or so everyone thought, until it seemws to be uncovered as a potential crypto scam, denounced even by the game’s original creator, Dong Nguyen, who confirmed he never sold his IP to anyone.

The new Flappy Bird game appeared on Sept. 12, with a tweet apparently pretending to be from the original creator Dong Nguyen marketing a return of the infamous title. However, it quickly became clear Nguyen had nothing to do with the game, saying in a Sept. 15 tweet, “No, I have no relation with their game.” He added that he “did not sell anything,” and denounced crypto, which the new Flappy Bird game seems to contain.
