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

Rules: Variation of Pentopia rules: Place some of the given pentominoes in the grid so that no pentominoes are in adjacent cells that share an edge or corner. 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.)

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.

Author/Opus: This is the 102nd puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Fill the grid with digits from the indicated range (1 to n) so that no digit is repeated within a row or column.

If there is only one visible cell, the clue number indicates the digit itself.

Answer String: Enter the digits in the 7th row from left to right, followed by a comma, followed by the 5th column from top to bottom. Ignore the triangled cells.

Author/Opus: This is the 109th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Standard Tapa-Like Loop Rules. (Form a single non-intersecting loop. Clues inside the grid represent the number of neighboring cells visited by the loop; if there is more than one number in a cell, each number should be represented with a separate loop segment. There is no 2×2 rule of Tapa in this puzzle. This example image should help:

Also, there are two windows in the upper left (blue) and lower right (red) of the grid. If a cell is used by the loop in one window, then the cell in the same position in the other window is not used by the loop.

Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. Separate each row’s entry with a comma. For the example, this would be “11,12”.
