Puzzle 1 


Below is a very special grid, around each shaded number are 8 white squares.

However, each white square should have a number from 1 to 7.

Once filled in, these 8 numbers will sum to the shaded number.

In addition, once completed correctly, no row nor column will contain a duplicate number within a white square.

For example, the top row may be 5 6 4 2 3 1 7, etc.

This is a very difficult puzzle, and many people resort to using a computer to help them, which is a challenge in itself.
