Normal sudoku rules apply.
Each grey cell is either maximum (higher than its four orthogonal neighbours) or minimum (lower than its four orthogonal neighbours).
Green cells are neither maximum nor minimum compared to their four orthogonal neighbours.
Digits separated by a white dot are consecutive. Not all dots are given.
Solution code: column 9

Nice placement of the special cells, they led to some very clever deductions!

Very nice, has some tricky parts but very satisfying when figuring things out.

Nice puzzle. When i first looked at it I couldnt believe that there was enough information to make only one solution but it works.
