LIBRARY  -- Answer: CHIP -- By Meredith McClurg

This one was straight crypto. And we tried the online services to make sure it wasn't immediately solvable by them, though of course you might find them useful for their replacement technology (or you could just make Excel do it for you).

Reading across and adding spaces as needed, these words describe a number of poker games. They are interesting to research if you enjoy the game, but something of a rathole if you get going on it.  To attempt to forestall that, we included the line "use cipher maps."

Here, you need to look also at what the crypt actually is. This is one place where the online services will make things a bit more difficult-- the ones I've seen don't show you this part. There are two ways to write out a map of the cipher: either alphabetic by ciphertext or by original text. If you look at the one ordered by original text (with the enciphered versions of the letters beneath them), you'll get the following:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
C A S H P R O X Y N W G I D V L T F B Z M J E U K Q

The first part of this is "cash proxy." In the context of poker, that is a CHIP.

 

Hints

  1. It's a standard cryptogram, with spaces adjusted to decrease the usefulness of computer auto-solvers.
  2. The last word is eight letters long.
