Crisscross with Pentominoes by Serkan Yürekli

PDF

or solve online (using our beta test of Penpa-Edit tools; use tab to alternate between a letter entry mode and a shading mode to mark off cells).

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:

or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode and the linex mode where left click+drag draws lines and right click marks X’s)

Theme: Clue Symmetry and Logic

Author/Opus: This is the 85th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place all twelve pentominoes into the grid a single time, rotations and reflections allowed. Pentominoes can touch each other, but cannot overlap. When all pentominoes are placed, none of them should be able to move in any of the four directions; pentomino movement is blocked by other pentominoes and by clue cells. Each clue cell contains the letters of all pentominoes that touch that cell, even diagonally. (A blank, black cell has no pentominoes touching it.)

Or see this example:

Frozen Pentominoes by Serkan Yürekli

Answer String: Enter a single CAPITAL letter representing each pentomino appearing from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma.
