# Problematics | Games of deduction before Wordle came

## As in Wordle, you use test words to deduce a secret word. What's the hidden word in the example below?

When Wordle first came out, the similarity with Jotto would have struck anyone who had ever played that older game. Jotto, described in The Penguin Book of Word Games by David Parlett, was invented in the United States by Morton M Rosenfeld in 1955. The game is played by two players: you think of a secret five-letter word, I think of another, and each of us tries to deduce the other’s word using “test words”.

Say, your secret word is LEGAL, and I call out CLEAN as my test word. You now respond with 3, which means 3 letters are common (L, E, A) between your secret word and my test word, in whichever positions. Note that you count only one of the two Ls in LEGAL, because CLEAN has only one L. If I call out GOLLY, however, you count both Ls and respond with 3 (G, L, L). And if I call out ELEGY, you respond with 3 again (E, L, G); the second E in ELEGY doesn’t count, because LEGAL has only one E.

Players call out test words alternately, until one of them deduces the other’s hidden word.

## #Puzzle 43.1

In this game of Jotto, you impose a restriction: the secret word cannot have consecutive vowels or consecutive consonants. Your test words and your opponent’s responses are as shown. Your opponent has not yet responded to the seventh test word.

## #Puzzle 43.2

A standard Chinese Checkers board has 121 slots to place your counters. Each player begins from a triangle with 10 slots (1 + 2 + 3 + 4); the first row outside each player's triangle has 4 + 5 + 4 = 13 slots. Using this information but without counting all the slots, what calculations would you use to determine that their total is 121?
