So, you want to know the secret to green glass doors? (Read how to play here.) You’re really really sure you want to know? Because you’re cheating yourself out of the fun if you do…

You’re still here?

OK, fine. Here it is: any word that is spelled with a double letter can go through the green glass doors, but any word that isn’t spelled with a double letter can’t (get the title of the game now?).

So, some things that could go through the green glass doors:

  • grass, but not flowers
  • a happy person, but not a sad person
  • mushrooms, but not a fungus
  • feet, but not toes
  • overalls, but not blue jeans
  • apples, but not bananas

Get the idea? It often takes so long for people to figure out because they focus on the relationship of the things named in the sentence rather than the spelling, which is why it’s fun for the players who know the secret to say phrases like the ones below, with objects that are related to each other in different ways:

  • a rabbit, but not a hare (two similar objects)
  • the moon, but not the sun (two opposites)
  • glass, but not a window (something that’s part of something else)
  • a hammer, but not a nail (two related objects)
  • pepper, but not salt (two things that make a pair)
  • a pineapple, but not an orange (two things from the same category)
  • a poodle, but not a dog (but a poodle IS a dog!)

“Hints” like these are sure to confuse players even more and prolong the oh-so-entertaining game. So now that you know the secret, use it wisely and have fun!


          1. I’m playing with me friend that doesn’t know how to play😂 I am dying laughing on my insides. She’s completely dumbfounded.!!!!!!!

    1. IT IS THE BEST GAME EVER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!*takes breath*!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

          1. Oh my god like I was so confused When my friend told me the green glass door and I was like the whaaaat and then I found this and I was sooo happy that I know I was so confused until now

    1. Haha, our high school basketball team used to play this on the bus to away games. It drove the players who didn’t know the answer crazy. It took me at least a year before I figured it out…

    1. You know, actually (and this is putting a lot of thought into it), I think this clue would be too much of a hint and would make it too easy for the guessers. Because “kid” and “kiddo” mean the same thing, the only difference is the spelling. That would clue the guessers in on the fact that the spelling matters most. That’s of course not what we want; we want the guessing to go on as infuriatingly long as possible 😉

  1. Before playing, I tell my students that if they figure it out, dont shout it out. Then we can continue and they are now in on it too. To let me know that they know the solition, they tell me 3 things in a row that may go, and 1 that can not. Awesome game! And I, Mr Seefeld can go even though teachers are not allowed through!

    Ive pondered other games like this with the same idea because the thrill og GGD may only be experienced once in a lifetime. True Blue Gate was my best one. Can you guess the rule now that you know green glass doors solution?

    1. Haha, that’s great. My best guess on True Blue Gate is words with a silent E? There’s also the game Going on a Picnic where players can make up their own rule each round. It’s not quite the same as Green Glass Doors, but it’s nice because you can keep playing again and again. Thanks for sharing, Mr. Seefeld!

  2. There’s a school with a roof, but no ceiling. No students either, but teenagers.
    There’s sleep but no bed, though there is a mattress. Lol

  3. A noodle can make it through, but not soup! No soup for you! Lol. I think I need to eat something.
    A platter goes in, but not a dish.
    A buddy gets through, but not a friend. (Aww. ) (pout.)
    A villain gets in, but not an enemy.
    I am entertained just making up related (in some way) words. Thank you for this game idea! ….I had never heard of it.
    Thanks! -Susanna (Susan, but I wanted through the door!).

  4. In the early 80s, while in Junior high was exposed to a game called Queen Anne’s Picnic.

    Same concept… “What would she bring with her to a feast?” Answers had to be double letters.

    Pizza, not meat pie

    Green beans, not red ones

    Carrots, not celery…


  5. A pillow can come, but a bed can’t. A bullet can come, but a gun can’t. Twitter can come, but Facebook can’t. Google can come, but the Internet can’t.

    1. Yep, you’ve got the concept! Personally I think when you have a two-word phrase (like green banana), both words should be able to go through the green glass doors. Technically, a banana (of any color) can’t go through. So I think saying a “green banana” can go through could potentially be confusing to someone.

  6. sports can’t but soccer, volleyball, skiing, basketball, kickball, football, tennis, football, handball and more can

  7. I didn’t think about it until I got to feet but not toes; toes are part of your feet! [Would my name count?] {My name has two of the same letter in it; just not right in a row.}

    1. The end game for an individual is when they personally figure out the secret. But they can keep playing and give clues for the other players. When everyone you’re playing with knows the secret, the game can be over. There’s not really one winner (I guess the last person to figure it out could be the loser?)

  8. The answer is clearly in the title of green glass door Because green can go through glass can go through and door can go through
