Theme: Logical.

Author/Opus: This is the 141st puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Place six pentominoes into each of the two top grids so that all twelve pentominoes are in one of the grids. Pentominoes can be rotated and reflected, but cannot touch each other not even diagonally. The numbers outside the grids indicate how many cells are used by pentominoes in that row/column. The shaded cells in the bottom grid must be part of a pentomino in one of the two top grids; the unshaded cells cannot be part of a pentomino in either grid.

Answer String: Enter the length in cells of each of the shaded pentomino segments from left to right for the marked rows, starting with the two marked rows in the left grid and then with the two marked rows in the right grid. Separate each row’s entry from the next with a comma.

Time Standards (highlight to view): Grandmaster = 3:30, Master = 6:45, Expert = 13:30

Theme: Quadruple Quandary

Author/Opus: This is the 12th puzzle from guest contributor Carl Worth.

Rules: Place some of the given pentominoes in the grid so that no pentominoes touch, not even diagonally. Pentominoes cannot repeat in the grid; rotations and reflections of a pentomino are considered the same shape. The arrow clues indicate all the directions (up, down, left, and right) where the nearest pentominoes are located when looking from that square. Also, see this example:

Pentopia by Thomas Snyder

Answer String: Enter the length in cells of each of the shaded pentomino segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma. The example has the solution “21,23”.

Time Standards (highlight to view): Grandmaster = 5:00, Master = 7:00, Expert = 14:00

Theme: Clue Symmetry and Logic (originally on 2016 Polish Puzzle Championship)

Author/Opus: This is the 119th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Place some of the given pentominoes in the grid so that no pentominoes touch, not even diagonally. Pentominoes cannot repeat in the grid; rotations and reflections of a pentomino are considered the same shape. The arrow clues indicate all the directions (up, down, left, and right) where the nearest pentominoes are located when looking from that square, ignoring the clue cell itself. (Pentominoes can sit on the clue cells.)

Crisscross with Pentominoes by Serkan Yürekli

PDF

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: 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.

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