(Published on 24. July 2009, 16:04 by pwahs)
Enter the digits from 1 to 7 into the grid such that in each row and column is each letter exactly once. If there is a white point between two numbers, their difference is one, and if there is a black point, their quotient is 2. If there is no point, none of those properties may hold.
Solution code: the last row
