In time for Christmas, the Cryptarithmania site is now live and online! You can sign up to receive cryptarithm puzzles in your email Inbox, or buy a CD of over 4 million cryptarithm puzzles. In case you don’t know what a “cryptarithm” is, it’s a puzzle where an arithmetic sum has been changed, replacing each digit with a different letter. Your goal is to figure out what each letter represents. These puzzles are often called alphametics, or crypt-arithmetics or letter or verbal arithmetic. The classic example is SEND + MORE = MONEY, where M represents 1, and… hey, but why should I spoil the puzzle for you! Hop over to www.cryptarithmania.com now and grab yourself some puzzles.
