Author/Opus: This is the 356th puzzle from our managing editor Serkan Yürekli.

Rules: Combination of Word Search and Meandering Words rules (see prior posts, and below). Each bold word in the given list should be either located as in a Word Search (possibly filling in missing letters in the grid) or should be placed in an outlined region as in a Meandering Words puzzle.

Meandering Words rules: Place a letter into each empty cell so that each outlined area has exactly one bold word from the given list. Cells that contain the same letter cannot be placed in adjacent cells that share an edge or corner. Each outlined area must contain the word from the first letter to the last letter such that consecutive letters within an outlined area are orthogonally adjacent. (In other words, for each region it must be possible to draw a path that starts at the first letter and ends at the last letter, going through each other cell exactly once.)

Word Search rules: Locate the bold words in the given list in the grid, running in one of eight possible directions horizontally, vertically, or diagonally. Some letters in the middle of the grid are missing and must be discovered while solving.

Difficulty: 4.5 stars (estimate based off competition points; timing standards not available from our usual testers)

30th Birthday Surprise by Prasanna Seshadri

From Prasanna: “This puzzle is meant to be a culmination of 10 years of authoring puzzles. I want to especially thank GMPuzzles for accommodating these special puzzles every year even if it may not have fit the regular schedules. I also see this puzzle as a “reset” of sorts, and I’ll get back to simple ideas to celebrate my next few birthdays, and then see where that takes me. These last 10 years have been a fantastic experience and I’d like to take this moment to thank the puzzle community as a whole for being a huge part of my journey.”

Theme: One Away from Thirty

Author/Opus: This is the 180th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Locate two snakes in the grid. Each snake must start from one of the gray circles, but has an unknown ending point. Black circles represent an interior cell of one of the snakes, and all black circles must be part of a snake. Each snake’s path is allowed to move vertically, horizontally, or diagonally between cells. An interior snake cell can only be adjacent to two other snake cells (including diagonally adjacent cells) and an end of the snake can only be adjacent to one other snake cell (including diagonally adjacent cells). The two different snakes must not share any adjacent cells.

There are some numbers outside the grid. These numbers indicate the number of vertical or horizontal edges (not corners) that snakes cross in that direction.

There are some letters inside the grid. For each distinct letter, exactly one of its instances is visited by one of the two snakes.

A/B Testing

Dear friends,

This weekend is the MIT Mystery Hunt and Grandmaster Puzzles is very happy to be a sponsor of this puzzle event in 2020.

If you are new to this site, there are lots of different fun genres of logic puzzles to explore and you can follow some of the links to the left to find these genres including our easiest puzzles to get started. The Intro to GMPuzzles and Logic Puzzles 101 books are some great titles to try as well.

As part of the pre-Hunt activities for the team I compete with, I created the attached puzzle set in the style of a Mystery Hunt puzzle. Like most puzzlehunt puzzles, it is missing some of the instructions you may want to have but I think you may still be able to figure it out. It has a final answer which is a word/phrase. We will post some hints and/or the answer in the coming weeks.

Theme: Clue Symmetry and Logic

Author/Opus: This is the 277th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place each of the given words into the grid, reading across or down; all words should interconnect, and all words formed in the grid must be from the list. Each given letter must be used by at least one word. Additionally, draw a Masyu loop: a single closed loop passing through each of the “O”s and otherwise using only unused squares. When passing through an “O”, the loop must go straight through and must make a 90 degree turn in at least one of the adjacent squares.

See also this example:

Example by Serkan Yürekli

Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. If the loop only has vertical segments in the marked row, enter 0. Separate each row’s entry with a comma.

Time Standards (highlight to view): Grandmaster = 7:00, Master = 10:45, Expert = 21:30
