Description: Cryptarithms are brain teasers obtained when digits in numerical calculations have been replaced by letters. Customarily, distinct letters stand for different digits. Another term, Alphametics, denotes cryptarithms in which letters form meaningful words, often in meaningful phrases [i.e., son to father: SEND + MORE = MONEY, and father to son: SPEND + LESS = SONNY]. This site offers Java implementations of various cryptarithms and alphametrics, as well as the opportunity to send in your favorites.
