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”.

Theme: Just Pentomino Letters

Author/Opus: This is the 86th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Locate the given words in the grid, reading across and down. All words should be interconnected and no words other than those in the word list should appear. All cells that are not part of the crisscross belong to one of the twelve pentominoes. Pentominoes can only touch each other at corners. Rotations and reflections of the pentominoes are allowed. The letters inside the grid are either part of the words, or part of a pentomino (and they must belong to a pentomino shape with that letter).

Or see this example:

Answer String: Enter all crisscross letters (ignore pentominoes) from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma. Use CAPITAL LETTERS.

Theme: Indian States (contributed by GMPuzzles to the Indian Puzzle Championship)

Author/Opus: This is the 180th puzzle from Thomas Snyder, aka Dr. Sudoku.

Rules: Variation of Nurikabe rules. Here, the islands are made up of words given in the list below the grid. The words must appear “snake-like” without forming 2×2 white squares or branching. Each given letter belongs to a separate word from the list. This example from the IPC instructions may be helpful:

Answer String: Enter the length in cells of each of the black segments (the unnumbered, connected “ocean”) from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.

Time Standards (highlight to view): Grandmaster = 4:00, Master = 5:30, Expert = 11:00

Solution: PDF; a solution video is available here.

Theme: Months

Rules: Place the 12 words into the grid, one letter per cell, so they can be read from left to right or from top to bottom, without crossing or overlapping each other. A dot between two cells indicates that both cells must contain the same letter. All possible dots are given. Or see this example from the WPC instructions.

Answer String: For each column from left to right, enter the number of unused cells in that column (eg “3510563449”).

Theme: String Lengths

Rules: Variation of Nurikabe and Scrabble/Criss-Cross puzzles.

Place the 12 number strings into the grid, reading from left to right or from top to bottom, so they are all connected criss-cross style and also form a valid Nurikabe ocean. No unlisted string can appear anywhere, not even two-character ones, and the strings do not occupy any 2×2 area. The remaining white cells are part of islands as in a Nurikabe puzzle. Each island is represented by one number in the grid which equals its size in cells.

Or see this example from the 22nd WPC instruction booklet.

Answer String: For each column from left to right, enter the total count of zeroes from the entered strings. Enter the result as a single string (eg “401120…”)

Theme: Hidden words (each row of letters forms an English word like SERF.)

Rules: Put each number (given as a word) into the grid, one letter per cell, as a snakelike strip which does not touch or cross itself. Some letters of the words are given. The remaining cells should be painted black to form a continuous wall as in a Nurikabe puzzle with no 2×2 shaded regions. Or see here.

Answer String: Enter the contents of each marked column from top to bottom, using X (capital letter) for each blackened square and capital letters for each island cell, and separating the columns with a comma.
