Hello! This is my first time uploading to Logic Masters, but I have been sharing my puzzles in the CTC Discord.

Play on SudokuPad!

Normal sudoku rules apply.

Mod 3 Arrows: A digit on an arrow indicates how many digits in the arrow’s direction have the same remainder when divided by 3, counting the digit itself. (eg a 2 on an arrow means that exactly two cells in that direction—including the 2 itself—contain digits from the set {2, 5, 8}, since those digits all leave remainder 2 when divided by 3).

Summit Lines: Digits along a blue line must be ascending or descending, with 1 and 9 reversing the ascension/descension. (eg if digits along a blue line are 2-4-5-7-9-8-5 in that order, the sequence is ascending until the 9 causes a descension).

Renban Lines: Digits along a pink line contain a consecutive set of digits in any order.
