Monday Mutant 93: Battleships (water groups)

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates the length of the longest group of consecutive water cells in that row or column. Additionally, some segments of the ships are shown within the grid, and cells with wavy lines are "water" cells which cannot contain ships. Find the ships.

Monday Mutant 88: Quad-Wrangle / Battleships

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. The cells which do not contain ships must be divided into rectangles according to the rules of Quad-Wrangle.

Monday Mutant 77: Proof of Quilt / Battleships

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown (without changing the numbers), but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates how many cells in that row or column are occupied by ships. These ships also function as black cells in a Proof of Quilt puzzle, and the numbers on some of the ship segments function as they normally would in such a puzzle. None of the black cells already present in the grid are part of the ships. Locate the ships and solve the Proof of Quilt puzzle.

This could be my strangest Monday Mutant in a long time.

Monday Mutant 76: Battleships (minesweeper)

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. A number in a cell indicates how many of the cells sharing a corner or an edge with that cell are occupied by ships. Cells with numbers cannot contain ships. Find the ships.

Combining Minesweeper and Battleships is probably one of the most ironic things that's ever happened in the realm of puzzles, since in Minesweeper, you want to avoid hitting mines, but in Battleships, you want to hit the ships.

Monday Mutant 69: Battleships

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates how many cells in that row or column are occupied by ships. Cells with wavy lines are "water" cells which cannot contain ships. Find the ships.

Monday Mutant 48: Battleships (all 3's)

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown (without changing the numbers), but may not overlap or occupy cells which share a corner or an edge. A number 3 to the right of a row or below a column indicates that three cells in that row or column are occupied by ships; the number of occupied cells in a row or column without a number must not be 3. Find the ships.

Note to solvers (courtesy of Jonah): read the rules, not just the title.

Monday Mutant 42: Battleships

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates how many cells in that row or column are occupied by ships. Additionally, some segments of the ships are shown within the grid, and cells with wavy lines are "water" cells which cannot contain ships. Find the ships.

Monday Mutant 41: Battleships

Thirty ships (as indicated below the grid: three four-cell ships, six three-cell ships, nine two-cell ships, and twelve one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates how many cells in that row or column are occupied by ships. Additionally, some segments of the ships are shown within the grid, and cells with wavy lines are "water" cells which cannot contain ships. Find the ships.
Now with 200% more ships and 189% more grid! Also, this doesn't count as part of my series of seventeen 17x17 puzzles.

Monday Mutant 22: Battleships (Shinro)

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates how many cells in that row or column are occupied by ships. No cell containing an arrow may contain part of a ship, but every arrow must point to at least one ship segment in that row, column, or diagonal (although not every ship segment needs to have an arrow pointing to it). Locate the ships.

This variant is inspired by a puzzle called Shinro, a puzzle apparently of Japanese origins.

Monday Mutant 21: Polyominous / Battleships

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown (without changing the numbers), but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates how many cells in that row or column are occupied by ships. The numbers on these ships also function as clues in a Polyominous puzzle. None of the numbers already present in the grid are part of the ships. Locate the ships and solve the Polyominous puzzle.
Today's Monday Mutant was inspired by the ever-so-inspirational Thomas Snyder.

Monday Mutant 20: Straight and Arrow / Battleships

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. A cell containing a number and an arrow represents how many of the cells in the row or column pointed at by the arrow contain ships, but may not itself contain a ship. All cells which do not contain a numbered arrow clue or a ship must be connected in a single loop of horizontal and vertical lines which doesn't cross itself or branch off, as in a Straight and Arrow puzzle. Locate the ships and draw the loop.
To my knowledge, Thomas Snyder was the first puzzlesmith to combine these two puzzle types.

Evil Zinger 9: Battleships

Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates how many cells in that row or column are occupied by ships. Additionally, some segments of the ships are shown within the grid, and cells with wavy lines are "water" cells which cannot contain ships. Find the ships.
I turn 23 today! To celebrate, I'll be posting Monday Mutant-style Evil Zinger (EZ) puzzles throughout the day. Are you prepared for some very difficult and very mutant puzzles? Of course not! Nobody is! BWA HA HA HA! I am so evil!

Monday Mutant 19: Process of Illumination / Battleships

Monday Mutants is a series in which I will attempt to experiment with "mutant" puzzles. These could be existing puzzle types with an unusual change in the rules, hybrids combining elements from multiple puzzle types, or puzzle types neither invented nor popularized by Nikoli.

If none of the other puzzles on this blog can be considered "mutants", this one most definitely can be.

Speaking of mutants, the day after tomorrow is my birthday! To celebrate, I will be posting more Monday Mutant-style puzzles just for the solving pleasure of you, my dear readers. Of course, since they're going to be posted on a Wednesday, I won't be able to call them Monday Mutants. Nonetheless, I believe you'll enjoy them. :)

ERRATUM: I must not be cut out for logic puzzles any more. This puzzle marks my second erratum in a month. . . *sighs* Water has been added to make this puzzle have a number of solutions that is closer to 1 than before. I originally had water in this location (as well as a bunch of other locations that proved unnecessary), but somehow failed to notice that removing it created an ambiguity. I'm terribly sorry.

Some of you who are already familiar with the genre of Battleships may be wondering why such a puzzle has been posted as a Monday Mutant. My justification is that, prior to the introduction of the Monday Mutant series, I've stuck to Nikoli's precedents as much as possible (I don't publish any puzzle type they don't, the givens in a Fillomino, Slitherlink, or Sudoku are always symmetrical, a 9x11 Kakuro never has entries longer than 5 digits, a Slitherlink never has two 0's sharing a corner or an edge, etc.). In the Monday Mutants series, I strive to make puzzles that are entertaining and logical, but worry less about these precedents. Suddenly, the precedent that a Sudoku puzzle never has any indicator of which pairs of cells contain consecutive numbers, for example, can be thrown out the window, if the resulting puzzle can be solved via logic and is entertaining and different enough to justify its existence. Battleships is a puzzle type "neither invented nor popularized by Nikoli", and as such, the precedent is not to publish them. This Monday Mutant abandons that precedent completely.
