About this game
Figure out the secret rule for what can go through the "green glass door."
How to play
One player knows the secret rule: only things with double letters can go through the green glass door. They give examples: "I can bring a book through the green glass door, but not a magazine." Other players guess what can go through by suggesting items. The rule-keeper says yes or no. Players try to figure out the pattern. Once someone guesses the rule, they can help give examples.
