Contrived Card Change! (Posted on 2005-03-15) Difficulty: 3 of 5
Some numbered cards were used to form numbers in a 3x3 grid. The sum of the numbers in all rows and columns should be the same, but isn't: the row totals are 34, 31 and 40, for example. Move only one card and make all totals the same!
