Rules:
Place the digits 1-9 once each into each row, column, and box within the main 9x9 grid.
Place a digit into every cell outside the grid. A digit outside a row or column is placed into the Nth cell in that row or column, where N is the first digit in that row or column.
A digit N on a circle counts the number of digits in the (up to 8) surrounding cells that are greater than or equal to N.
Digits outside the grid are counted.
Have fun solving!
Solution code: Column 8 of the 9x9 grid from top to bottom (9 digits)

Very nice! For me the break-in was obscure and I could only find it by a little bit of bifurcation, which means I did not find the intended and proper way. Enjoyable solve afterwards, thanks!
