Games Online Contest #15

5 First Prizes: A one-year subscription to GAMES

This contest closed on December 31, 2007. A new contest will appear soon.
Here was the challenge:

Just Twelve Words

This list of a dozen closely related words (none of which are proper nouns) has been encrypted using a simple letter substitution cipher. Letter substitutions remain constant throughout the list—thus, Z represents the same letter of the alphabet in each of the first seven words on the list. Letters cannot stand for themselves.

Can you decrypt the list? Hint: If you solve correctly, the list will be in alphabetical order.

DUODECIM
