Theme: Logical

Rules: Variation of Fillomino rules where regions with the same shape must avoid each other instead of regions with the same size (all regions in a pentominous puzzle are pentominoes). See an earlier Pentominous puzzle here.

Specifically, divide the grid into 45 pentominoes so that no two pentominoes of the same shape (including rotations/reflections) share an edge. A cell with a letter in it must be part of the pentomino shape normally associated with that letter as given below the grid. Not all pentomino shapes need appear.

Answer String: Enter the letter associated with the pentomino occupying each cell in the marked rows from left to right, separating the rows with a comma. Use CAPITAL LETTERS!

Theme: Logical

Rules: Hybrid of Battleships and Criss-Cross (Nansuke) puzzles:

Place the given fleet into the grid so that no two ships touch, even diagonally. In the remaining unused cells, place the given numbers criss-cross style so that they can be read from left to right or from top to bottom. All possible entries with two or more connected digits are given.

Answer String: Entry the contents of the two marked columns from top to bottom, using a capital X for any cell with a ship segment.

Theme: Logic

Rules: Hybrid of Nurikabe and Sashigane, originally created by Grant Fikes. Standard Nurikabe rules are in place for the “ocean” (connected and no 2×2 squares) but the island rules have changed as follows:
1. All islands must be L-shaped and one cell wide. Islands cannot share an edge.
2. An arrow clue points from an end of an island towards the bend in the middle.
3. A circle clue indicates the bend in the middle of an island; if a number is also present, this is the size of the island in cells.
4. An island can have 0, 1, or more of these clues given.

Also see this example and solution by Thomas Snyder:

Answer String: Enter the length in cells of each of the black segments (the unnumbered, connected “ocean”) from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.

This is a “Twisted Tuesday” puzzle variation.

Theme: Logical

Rules: Variation of Fillomino rules where regions with the same shape must avoid each other instead of regions with the same size (all regions in a pentominous puzzle are pentominoes).

Specifically, divide the grid into 20 pentominoes so that no two pentominoes of the same shape (including rotations/reflections) share an edge. A cell with a letter in it must be part of the pentomino shape normally associated with that letter as given below the grid. Not all pentomino shapes need appear.

Answer String: Enter the letter associated with the pentomino occupying each cell in the two marked rows from left to right, separating the rows with a comma. Use CAPITAL LETTERS!
