A player (it) has a word and other players try to find out the word by making guesses in turns.
The first guesser just says a random word, and in response the it tells where its word is relatively located in a dictionary, by giving an interval.
The next guesser tries a word in the interval.
Whoever finds out the word becomes the new it.
Example: The it has the word 'now'. The first players makes the random guess 'here'. In response, the it has to say 'between here and Z'. The next player selects a word from this alphabetical
interval, and says 'there'. The next clue from the it would be 'between here and there'. The game continues until a player finds 'now'.
