Normal Sudoku rules apply.
If there is a digit in the corner of a cell containing the value N, it's the number of copies of 7, 8 and 9 at exactly N cells of distance orthogonally from this cell, in a straight line.
For instance, if you place a 5 in a cell with a 2 in the corner, then there are exactly 2 cells at distance 5 in a straight line that contain a 7, an 8 or a 9.
All the possible digits are given. This means that empty cells are considered as having a clue of 0.
Enjoy!
Solution code: Row 7, row 8

At first I thought these rules seemed too complicated, but it actually is really easy to understand and get going with. I really enjoyed it. Super fun puzzle. Well done!
