Logic Masters Deutschland e.V.

This was set for Scojo's Setting Saturday prompts. The prompt was to create a puzzle using Monstrifier cells, a monster based modifier!

I chose to create two puzzles based on a ruleset around the Headless Horseman from The Legend of Sleepy Hollow! You can find the more difficult sequel to this puzzle here.

The Legend of Sleepy Hollow is an American folk story written in 1820 that was excellently animated by Disney in 1949. It is worth checking out if you have never seen it!

Thanks to MattYDdraig, Nebuzaradan, and aqjhs for testing!

Rules:

• Normal sudoku rules apply.

• Values along purple renban lines are consecutive.

• Clues outside the grid give the sum of values along the indicated diagonal.

• Headless Horseman Cells
  • Place nine Horseman cells so there's exactly one in each row, column and box.
  • Digits within Horseman cells may not repeat.
  • Cells containing a 🎃 (pumpkin) are given Horseman cells.
  • Two Horseman cells may not be a chess knight's move apart.
  • Horseman cells have a value of 0.
  • The values of all cells a chess knight's move away from a Horseman cell are increased by the digit in that Horseman cell.
