Independent Pursuits: Puzzle
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.IN ONE of his books on mathematical diversions, Martin Gardner mentions a nice word game invented by Anatol W Holt. One player thinks of a three-letter word; the other then makes a series of guesses at the word and is told each time whether the number of "hits" (right letters in the right place) is odd or even. The object is to determine the word in as few tries as possible. Try this one:
DAY, MAY and BUY score an even number of hits; SAY, DUE and TEN score odd. What is the word?

Answer to yesterday's puzzle:

(9, 3, 0) - (9, 0, 3) - (1, 8, 3) -
(1, 6, 5) - (6, 6, 5).
