This puzzle was constructed on Rangsk's stream with help from the community! This was an event to celebrate Rangsk getting 1000 subscribers!

Rules:

  • Normal sudoku rules apply.
  • Indexing Arrows:
    • Digits on an arrow sum to the value in the diamond.
    • If the arrow is horizonal then the digit in the diamond indicates where the column number of the diamond appears in the row, e.g. if r9c5 is a 7 then r9c7 is a 5.
    • Similarly, if the arrow is vertical then the digit in the diamond indicates where the row number of the diamond appears in the column, e.g. if r2c7 is a 5 then r5c7 is a 2.
    • If a diamond has arrows in both directions then it follows both rules.
  • Here's an example puzzle created by Xenonetix to help understand the rules:
