This puzzle has a sting in the tail, so I've provided a hint below the image that you may use as you wish.
Rules:
Place the digits 1-9 once each into every row, column, and box.
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.
A digit N on a square counts the number of digits in the up to 8 surrounding cells that are less than or equal to N.
Hint: R8C6 could contain a square
Have fun solving!

Great exercise for me, because I am terrible at puzzles with this kind of ruleset. I switched a square with a circle in my head and got stuck for an hour for example. Thanks!
