The November 1989 Word Ways reviewed Recreational Mathemagical Software (Clarks Summit PA) designed for playing the game of Jotto with a computer. In the two-person game of Jotto, each person selects a five-letter target word; the object is to guess your opponent's word before he guesses yours. To identify his target word, you propose a sequence of five-letter words, and your opponent tells you how many letters of the guess word are in his target word. For example, if the target word is PIVOT, THOSE scores 2 (T,O match) and MUNCH, 0. You and your opponent agree beforehand on a dictionary of allowable guess and target words (the Official Scrabble Players Dictionary is useful here).
