In the lead up to the game's release, YouTuber Dawko made a bet with Scott Cawthon that if he 50/20 mode, the game's hardest setting, then Scott would have to do an interview on Dawko's YouTube channel. If Dawko lost, he would have to make a fan game called "FANF7". On July 9th, 2018, Dawko completed 50/20 mode and Scott did the interview on August 8th, 2018, the fourth anniversary of the first game.
