Green Glass Door is a word game in which participants must repeat the words with their interpretation of the rule to figure out the hidden rule. If you’re searching for camp games for small groups, this is a great option. If you’re searching for something to play with other games like Cops and Robbers or Horse Race, the game may also be used as a drinking game.

A player gets dismissed from the game if they try to pass something through the Green Glass Door game that isn’t three letters long. Tell the offending player, ‘You can’t make it through the glass door.’

Do you get it? People often take so long to figure out because they focus on the relationship between the things named in the sentence rather than the spelling, which is why it’s entertaining for players who know the secret to say phrases like the ones below, with objects that are related to each other in various ways:

  • not a hare, but a rabbit (two similar objects)
  • not the sun, but the moon (two opposites)
  • Glass, but not a window (which is a component of something else)
  • not a nail, but a hammer (two related objects)
  • salt, but not pepper (two things that make a pair)

These kinds of “hints” are guaranteed to perplex players, even more, extending the oh-so-entertaining game.

What are your options for playing the game?

Although having something to write things down on, such as a whiteboard, may help participants keep track of the game, no further equipment is required. If you decide to play this as a drinking game with your adult friends, each individual will need their drink.

The game has begun.

You must first think of various responses for other players to uncover before you can begin playing the game. Start with a simple rule, such as needing three letters for anything entering through the door. Once you’ve come up with a few ideas, gather everyone in a circle and start the game.

How to Play the Green Glass Door Game

The statement I can get a ‘through the window, but I can’t get a ‘through the window is repeated several times during the game. The two words are substituted with terms that initially follow the rule before breaking it.

If you follow the three-letter rule for the first round, I can take a basket through the window, but not a washing machine. The next person in the circle must then repeat the statement while guessing the rule by substituting their own instances for the terms.
