THIS WAS THE FIRST BOSS PUZZLE THIS YEAR WITH A BOSS RATING OF 4. Maybe you found it easier than Harry, and if so, hat tip to you! Either way, we hope you enjoyed it!
In the completed puzzle the numbers 0 through 9 appear in each of the top six rows of the grid so that they give the column sums at the bottom and no number appears in twice in adjacent cells, including diagonal adjacency.
