Theme: Pentominoes (originally on the US round for the 2016 WPF Puzzle Grand Prix)

Author/Opus: This is the 238th puzzle from Thomas Snyder, aka Dr. Sudoku.

Rules: Variation of Nanro.

Label some cells with numbers to form a single connected group of labeled cells. No 2×2 group of cells may be fully labeled. Each number must be equal to the total count of labeled cells in that bold region, and all bold regions contain at least one labeled cell. The given numbers indicate how many cells are labeled in that region (but not necessarily which cells are labeled). When two numbers are orthogonally adjacent across a region boundary, the numbers must be different.

Also see this example:

Answer String: Enter the length in cells of each of the segments labeled with numbers from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.

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: 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.

Theme: Clue Symmetry and Logic

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. Number clues in the grid indicate the difference between the largest and smallest digits in the visible cells (i.e., going from the clue until hitting an edge or another triangled cell). 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.
