Remainder Snakes

(Published on 15. March 2024, 18:56 by wuc)

Normal sudoku rules apply.

Draw two snakes in the grid - a mother snake with head and tail on the two squares (they contain even digits) and a baby snake with head and tail on the two circles (they contain odd digits). A snake is a one-cell-wide path of orthogonally connected cells which may not touch itself, not even diagonally. Both snakes act as a modular line: every three adjacent digits must contain one digit of each of the groups 147, 258, 369.

Both cells of difference dominoes (adjacent digits have the given difference) must be on a snake. All cells of killer cages (digits in cages sum to the total - if given - on the top left corner) must be on a snake.
