Green Glass Door Game

About

The Green Glass Door Game is a riddle game where one person tells another or a group of people that there is a green glass door that some things can pass through and others cannot, giving a few examples of things that can pass and things that can't, then allowing the other player(s) to ask if specific things can pass or not in an attempt to learn what can and can't go through the door. The answer to the riddle is that any words that have double letters, such as "green," "glass" and "door" can pass and words that do not can't. The game has been shared online since as early as 1999 and went viral on TikTok in November 2022 after a user played the game with her boyfriend.
