I have never ever heard of a game coming with a help hotline. And I played a lot of games in that time. TIL that

one classic example is the game “The Legend of Zelda” for the NES. The game contained cryptic puzzles and secrets that were not easily solvable. Nintendo provided a hotline, called the Nintendo Power Line, where players could call in for tips, tricks, and solutions. Calls to the hotline were not free, creating an additional revenue source for the company.
