The Green Glass Door
The Green Glass Door is a common word game where a player already introduced to the game (understands the 'trick' to it) gives clues to a new player about what does or does not belong behind the 'green glass door'.
Basically, all the clues will have words that have exactly 2 duplicate letters which belong inside the green glass door. It is better to have the two items mentioned related in some way to greater confuse the individuals participating in the riddle.
Some examples:
- Behind the door you may attend classes at school or college but not courses at a university.
- Minnie Mouse is in, Mickey Mouse is not.
- Stellar is in, lunar is out, but moon is in and stars are out.
- Buttons and zippers are behind it, snaps aren't.
- Flowers may bloom there but they don't grow there.
- There is Bill, but no Clinton. Chelsea will have to wait outside.
- The U.S.S.R. is in, but the Union of Soviet Socialist Republics is not.
- There are sleeves but no clothes
- There are coops but no chickens
- There are swimmers and pools, but no lanes or competition.
In a similar vein:
- A stool is behind the green glass door, but a keyboard is not. (no relation)
- Mattresses are behind the green glass door, but a speaker is not. (no relation)

Another set of examples:

The reverse of this game is known as the Red Plastic Window, in which each word with no double letters is behind the Red Plastic Window.
- There are animals but no sheep
- There are lifeguards but no swimmers
etc.
Other common variations of the Green Glass Door are Moody's Grill and Bobby's World. Things with double letters are said to be in Moody's Grill, or can be taken to Bobby's World, other things are not. In England, a common variation is talking about what Harry the Hippo does (double letters) and does not like.
