Normal Sudoku rules apply.

Red lines must contain a set of consecutive, non-repeating digits in any order (Renban lines).

Digits may not repeat along the main diagonals (marked by dotted lines).

Digits separated by a white dot must be consecutive. Not all dots are necessarily given. (Kropki)

Digits on an arrow indicate how many cells away the nearest consecutive digit is in the arrow's direction. Not all arrows are necessarily given. A digit on an arrow may repeat in the arrow's direction before the nearest consecutive digit, if allowed by other rules. For example, a 3 placed on a southeast-facing arrow in r1c2 indicates that r4c5 must be either 2 or 4, and neither 2 nor 4 can appear in r2c3 or r3c4; however, 3 may repeat in r3c4.

This is the first sudoku I have created :) It is very difficult, but solvable without (much) brute force.
