Meandering Word Search by Serkan Yürekli

PDF

or solve online (using our beta test of Penpa-Edit tools; use tab mode to shift between letter entry, line drawing, and shape entry — for word list marking — modes)

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)
