There is an old adage that one person’s “creativity” is another person’s “cheating”. This week’s puzzle will test which side of the fence you sit on.
The numbers 1 to 9 have been written on cards and left on a table: the left-hand column adds up to 21 and the right one to 24. Move just one card so that the two columns add up to the same total. There’s a classic “Aha!” solution to this puzzle, but my daughter came up with a solution I wasn’t expecting. Since then, I have been offered at least 10 more distinct solutions.
