Schedule for Next Week

A PDF of our most recent variety week of very hard guest contributions can be found here.

This coming week features several Japanese authors who contribute to the Toketa book series (Volume 5 is coming out soon and copies will be at the World Puzzle Championship in India this month). Our week of puzzles features two genres that have appeared in Toketa: Sunglasses and Snake Pit X.

Our patrons will also be receiving a bonus Tapa (Transparent) by Serkan Yürekli who also contributes to Toketa, access to puzzle solutions, and a video walkthrough of the Saturday puzzle. If you’d like to receive some of these special rewards, please become one of our patrons on Patreon.

Note: Due to WPC preparation, and my completing a purchase and move to a new house, the next week of puzzles will probably post no sooner than 10/30.

Snake Pit X by Nikolai Beluhov

Snake Pit by Nikolai Beluhov

PDF

Theme: XOXOXO (+ Antisymmetry)

Author/Opus: This is the 4th puzzle from guest contributor Nikolai Beluhov.

Rules: Divide the grid along the boundary lines so that every cell belongs to a snake. A snake is a one-cell-wide path at least two cells long that does not touch itself, not even diagonally. Circled cells must be at one of the ends of a snake. A snake may contain one circled cell, two circled cells, or no circled cells at all. Numbered cells must be part of a snake with a length of exactly that number of cells. A snake may contain one number, multiple identical numbers, or no numbers at all. Two snakes of the same length cannot touch each other horizontally or vertically. Cells with an X cannot be an end of a snake.

Also see this example:

Snake Pit

Answer String: For each cell in the marked columns, enter the length of the snake it belongs to. Enter just the last digit for any two-digit number. This example has the key “33553,44664”.

Time Standards (highlight to view): Grandmaster = 11:30, Master = 17:30, Expert = 35:00

Cross the Streams (SLICY) by Bryce Herdt

Cross The Streams (SLICY) by Bryce Herdt

PDF

Theme: Logical

Author/Opus: This is the 11th puzzle from guest contributor Bryce Herdt.

Rules: Variation of Cross the Streams. Instead of the “no 2×2 shaded square” rule, in this hexagonal grid no 3 cells that share a point can be shaded. Also, the shaded region must be able to be split into tetrahexes to form a valid SLICY solution (meaning all tetrahexes are connected but no two tetrahexes sharing an edge are the same shape, including rotations and reflections).

Answer String: Enter the length in cells of each of the black segments from left to right for the marked rows, going in order from A to B to C to D and separating each entry with a comma.

Time Standards (highlight to view): Grandmaster = 5:30, Master = 8:15, Expert = 16:30.

Cross the Streams (LITS) by Bryce Herdt

Cross The Streams (LITS) by Bryce Herdt

PDF

Author/Opus: This is the 10th puzzle from guest contributor Bryce Herdt.

Rules: Standard Cross the Streams rules. Also, the shaded region must be able to be split into tetrominoes to form a valid LITS solution (meaning all tetrominoes are connected but no two tetrominoes sharing an edge are the same shape, including rotations and reflections).

Answer String: Enter the length in cells of each of the black segments from top to bottom for the marked columns, going in order from A to B to C to D and separating each entry with a comma.

Time Standards (highlight to view): Grandmaster = 7:00, Master = 10:30, Expert = 21:00.

Cross the Streams (Comparison) by Joseph Howard

Cross The Streams (Comparison) by Joseph Howard

PDF

Theme: Logical

Author/Opus: This is the 2nd puzzle from guest contributor Joseph Howard.

Rules: Standard Cross the Streams rules. Also, some sets of row/column clues have comparisons made to the left-most or upper-most ? clue. The value used for a ? clue must also be used for the remaining comparisons in that row/column (e.g., if ?, ?+2 the values could be 1, 3 or 2, 4 or 3, 5). ?= means a later clue has the same value as the first ?.

Answer String: Enter the length in cells of each of the black segments from top to bottom for the marked columns, going in order from A to B to C to D and separating each entry with a comma.

Time Standards (highlight to view): Grandmaster = 7:30, Master = 12:00, Expert = 24:00.
