Place the digits 1-9 so that they do not repeat in any row, column, or 3x3 box.

Fog of War
Most of the grid is covered in fog. Placing correct digits reveals the fog, no guessing is required..

5's live in Dutch Flats
All 5's in the grid must have a '1' directly above it or a '9' directly below it. It may have both, but it doesn't need both.

Knight Cages
Within a cage, only cells for which there is at least one other cell with the same digit a knight's move away from that cell, count toward the given total for the cage. Cage totals appear in the top left corner..

Special Thanks

Hint 1 - Where to start

Some cells have few knight move options, and it's tricky to make the cage total work.

Check clues, you may have deduced a digit but not placed their Knight friend yet. Don't forget Dutch Flats, which are a little trickier in this puzzle than normal.

If you have filled in most of the first 4 columns, R4C5 is a cell that is worth considering.

First, please reapply Hints 1 and 2 - lol - If you're in Box 9, look at the [3] cage before the [15] cage.
