==== RULES ====
Normal Sudoku rules apply : fill the grid with digits 1 to 9 appearing each exactly once in every row, column, and 3x3 box.
Min/max : Grey cells with arrows pointing inwards contain a digit strictly smaller than all its orthogonal neighbors. Grey cells with arrows pointing outwards contain a digit strictly bigger than all its orthogonal neighbors.
Oddruples : Circles indicate the number of odd digits in their surrounding 2x2 area. Digits may repeat around an oddruple clue (if allowed by other rules).
==== THANKS ====
Credit goes to Zombie Hunter for coming up with the very cool oddruples ruleset. You can find his original Oddruple puzzle here. Also, big thanks to him and Sir Schmoopy for testing and giving precious feedback.
Solution code: Digits from row 9 (left to right), and then column 3 (top to bottom)

Either I missed some logic, or this is a much more difficult puzzle than you give it credit for. Still fun.

In particular, the MinMax designation has been used for a different variant -> replace with Maximum (Variant).
