FourCast (Hidden Arrow Sudoku)
(Published on 13. December 2021, 05:52 by Nordy)
Cast (archery): the distance that a bow can shoot an arrow.
Rules:
Normal Sudoku Rules apply: the digits 1 to 9 must appear in every row, column, and 3x3 box.
Cells with gray squares must contain even digits.
Arrow rules apply: digits along arrow stems sum to the digit in the corresponding circle—except all of the arrow stems are hidden. Each circle has exactly one hidden arrow stem that is 3 cells long and extends from its circle in a straight line, either horizontally or vertically. Arrows may not cross, overlap, or share cells with other arrows.
This analogy may be helpful: arrows fit into the grid like I-Blocks (or line pieces) in Tetris, where each I-Block has a single circle at one of its ends.
