Even Corners and Equal Subgrids (Posted on 2009-08-18) Difficulty: 2 of 5
Each of the capital letters in bold in this 3x3 grid is to be substituted by a different digit from 1 to 9 such that :
  • Each of A, C, G and I is even, and:
  • The sum of the digits in each of the four 2x2 subgrids is equal.
A   B   C
D   E   F
G   H   I

Disregarding the rotations and reflections, how many distinct solutions are there?
