Theme: Clue Symmetry and Logic

Author/Opus: This is the 94th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Add letters to some empty cells to make a snake that doesn’t touch itself, not even diagonally. The snake’s head and tail are indicated by circles. The snake is made out of spelled out numbers, and some letters are given that must be part of the snake. Each numbered cell indicates the total sum of the distinct words that touch that cell, including diagonally. Not all words need to be used, but no word is used more than once.

Answer String: Enter the length in cells of each of the snake segments from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma. The answer to the example is “3,31”.

Time Standards (highlight to view): Grandmaster = 4:30, Master = 7:30, Expert = 14:00

Besides the snake, the remaining cells must form exactly nine white areas, one of each size from 1 to 9. Numbers in the grid must be part of white areas of the indicated size.

Theme: Quadrilaterals

Author/Opus: This is the 92nd puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Draw a snake (a 1-cell wide path) from one dot to the other by moving horizontally or vertically between adjacent squares. The snake cannot touch itself, not even diagonally. All highlighted regions must be visited by the snake, and may be re-entered. If two or more highlighted regions have the same shape and orientation, then how the path passes through those shapes must be identical.

Answer String: Enter the number of cells used by each snake segment from left to right for the marked rows, starting at the top. Use both digits for any two-digit number. Separate each row’s entry with a comma.

Time Standards (highlight to view): Grandmaster = 2:00, Master = 3:45, Expert = 7:30

Pentominoes can be rotated/reflected, and can be used more than once. The letters outside the grid represent the first pentomino visible in the corresponding direction.

Answer String: Enter the number of cells used by each of the snake segments from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma. The example has the answer “211,231”.

Theme: Solar System (words come from Italian, French, Hindi, Norwegian, Greek, English, Welsh, Farsi, and Arabic)

Author/Opus: This is the 89th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place the words into the grid (one letter per cell) so that they do not touch each other, not even diagonally, and so that they can be read in a straight line in a vertical or horizontal direction. Some letters in the words are already given in the grid. Then find a path that passes through every cell of the grid, starting with the first letter of the first word, passing through the words in order from their first letters to their last letters, and ending at the last letter of the last word.

Or see this example:

Answer String: Enter the number of turns the path takes between each of the words in order as a single string of numbers. (Ignore turns in cells with letters.) The answer for this example is “224”.
