Logic Masters Deutschland e.V.

In December 2023, I participated to the Secret Satan event on Discord. With permission of my "victim" Tob Snibbob (aka. majorprofanity), I am sharing here the gift I made for them. This is the first of the 2 puzzles I made. It should be relatively approachable (estimated 3-4). The other puzzle, which is probably a bit more challenging, was a hidden puzzle that was revealed after solving the first one. I will share it here in a few days. I hope you enjoy !

The puzzle :

Play on Penpa

Rules :

Kakuro :

- In each white cell of the grid, place some digits from 0-9, so that no digit repeats in a "word" (i.e. an horizontal or vertical block of white cells situated between 2 grey cells, or between a grey cell and the border of the grid).

- The numbers in grey cells indicate the sum of digits in the corresponding "word" (bottom left clue for a vertical "word", top right clue for an horizontal "word")

S-cells :

Some cells in the grid are S-cells and contain 2 digits. A "word" may contain exactly one S-cell or none. There can be several S-cells in a row/column, as long as they are all in different "words".

Loop :

- Draw an oriented closed loop, joining the centers of some orthogonally connected white cells. The orientation of the loop has to be discovered.

- The loop has to pass through every S-cells.

- One of the digits in an S-Cell indicates the distance to the next S-Cell on the loop.

- The loop may not go through a cell with a 0, including if it is in an S-Cell.
