Normal sudoku rules apply.

Anti-Knight: two cells a knight's move apart cannot contain the same digit.

Usual stuff: Thermometers and kropki dots behave as per standard rules for them.

Extra Regions: The two cages act as extra regions. They contain the digits 1-9 once each.

1234-Circles: The four circles contain the digits 1-4 once each, and each circled cell is less than all orthogonally adjacent cells.

6789-Squares: The four squares contain the digits 6-9 once each, and each squared cell is greater than all orthogonally adjacent squares.

There are no negative constraints of any kind in this puzzle. Coloring is for aesthetics only.

Have fun!
