Theme: Clue Symmetry and Logic

Author/Opus: This is the 3rd puzzle from guest contributor Takeya Saikachi.

Rules: Draw a route that starts at the gray Start circle (S) and passes through adjacent cells without crossing itself or revisiting any cells. Some cells may not be part of the route. White circles with letters represent packages that are to be picked up and delivered to the black circles marked with the same letter. The carrier has a maximum capacity of packages that can be handled at once, shown below the grid. The carrier must pick up and deliver all packages on the route, returning to S with no packages in hand.

Theme: Rectangles

Author/Opus: This is the 2nd puzzle from guest contributor Ken Endo.

Rules: Variation of Nanro and Nanro Signpost puzzles.

Label some cells with numbers to form a single connected group of labeled cells; no 2×2 group of cells may be fully labeled. Each bold region must contain at least one labeled cell. The small clue numbers indicate how many cells in that region are used. When two numbers are orthogonally adjacent across a region boundary, the numbers must be different. Each bolded region must be visited twice (i.e., have exactly two distinct connected groups inside it).

Schedule for Next Week

Our most recent week of Kakuro puzzles is in this PDF.

For the second time, we are featuring a special variety mix week from several of the Japanese authors who make the Toketa book series (link to PDF from 2017’s Toketa week). We will have three different variations — primarily new puzzle styles from the most recent volume — with two puzzles each over the week. Toketa Volume 6 came out at the end of last year, and played its own special role in my winning the World Puzzle Championship (link to my long report).

Our supporters will also be receiving a bonus Battlestar by Grant Fikes and a Snake Pit by Serkan Yürekli who also contributes to Toketa, access to puzzle solutions, and a video walkthrough of the Friday and Saturday puzzles. Last weekend, our grandmaster supporters also received three large bonus puzzles: a Kakuro by Hatice Esra Aydemir, a Tapa LITS Distiller by Grant Fikes, and a Crisscross by Grant Fikes. If you want to become a subscriber and get access to bonus puzzles, solutions, e-books, and other rewards, check out this page.
