Normal sudoku rules apply. The digit in the red cell (r1c1) is high [6,7,8 or 9]. The digit in the blue cell (r9c9) is low [1,2,3 or 4]. Digits along a purple line form a set of non-repeating consecutive digits (which can be in any order). Adjacent digits along a green line must have a difference of at least 5. A digit in a yellow cell must be greater than all of the orthogonally adjacent cells.
