Battleship Solitaire

Q: What should I do first?

Start by checking rows or columns with '0' to mark them as water, then handle rows or columns with large numbers and create a strategy using the ship icons.

Q: What should I do if I'm unsure where to place a long ship?

Check spaces that match the ship's length, consider other ships' positions, and identify the only possible location if available.

Q: How do I place a ship of a specific size?

Prioritize larger ships by checking the icons, narrow down fitting spaces, and complete partially placed ships if applicable.

Q: What should I do if I get stuck?

Review rows and columns, make temporary placements, fill water around placed ships, and focus on remaining spaces for fitting ships.

How to Play Battleship Solitaire

Battleship Solitaire is a logic game where you find hidden ships on a board designed to resemble the ocean. This page provides a clear explanation, from the basic rules to specific solving strategies.

Each time you click or tap on a cell, its state cycles in the following order:
Water → Ship → Blank → Water → Ship... in a loop.
By clicking or tapping and dragging to adjacent cells, you can change the states of multiple cells consecutively.
The numbers written at the top and left edges of the board indicate the number of ship parts in each corresponding row or column. For example, if the number is "3," it means that row or column contains three ship parts.
Ships must be separated by at least one cell in all directions. They cannot touch each other vertically, horizontally, or diagonally.
The black icons indicate how many ships of each size are hidden on the board.
The game is complete when you find all the ships and fill the board correctly.

How to Solve Battleship Solitaire

Follow the steps below to solve Battleship Solitaire.

Game start! Check the number of ships using black icons

1) Game start! The black icons show all the ships hidden on the board.

Filling rows and columns with 0 numbers with water

2) Rows and columns with a number 0 have no ship parts. Fill them completely with water.

Filling water to the left of a ship to avoid contact

3) Ships cannot touch each other, so fill the water to the left of the ship at the top.

The space next to the ship tip is also a ship part

4) The ship part at the top is the tip of the ship, so the space to its right is also a ship part.

Filling water around the ship at the right edge

5) Fill the water around the ship at the right edge to prevent it from touching other ships.

The space to the left of the bottom ship tip is also a ship part

6) The bottom ship part is also the tip, so the space to its left is a ship part.

7) Fill the water around the bottom ship to ensure it doesn’t touch other ships.

Marking water in a column with a number 1

8) The second column has a number 1, so no more ship parts can be placed here. Fill the rest with water.

Identifying a ship part in a column with number 2 and one empty space

9) The third column has a number 2 and only one empty space left, which must be a ship part.

Filling water in a row based on its number

10) Check the number in the fifth row. Since no more ship parts can be placed here, fill the remaining spaces with water.

Completing the row with a number 4 and two empty spaces

11) The third row has a number 4. With two ship parts already placed and two empty spaces remaining, these spaces must all be ship parts.

Filling water in a column based on its number

12) The fourth column has a number 2, and two ship parts are already placed. Fill the remaining spaces with water.

Placing a length-3 ship in the only possible space

13) Check the black icons. A length-3 ship hasn’t been placed yet, and there’s only one possible spot for it. Place the ship there.

14) The first row has a number indicating no more ship parts can be placed. Fill the remaining spaces with water.

Marking water in a column based on its number

15) Check the fifth column. Since no more ship parts can be placed, fill the remaining spaces with water.

Completing the game by identifying the last ship part

16) Based on the numbers in the sixth column and sixth row, the last empty space must be a ship part. Game complete!

Battleship Solitaire Q&A

Q What should I do first?

A Follow these steps to smoothly start the game:

Look for rows or columns with the number "0"
These rows or columns contain no ship parts, so fill all cells with water. This is a very effective first move.
Check rows or columns with large numbers
If the number matches the total number of cells in the row or column, all cells are ship parts, so fill them all.
Check the black icons
Understand the size and number of ships to be placed and plan your overall strategy.

Q What should I do if I'm unsure where to place a long ship?

A Long ships have limited placement options. Use the following methods to identify their placement:

Check available spaces
Look for spaces that fit the ship's length and avoid cells already occupied by other ships or water to narrow down the placement options.
Consider the position of other ships
Ensure the placement of the long ship does not interfere with adjacent ships by following separation rules.
Find the only possible space
If there is only one space that fits the ship, place it there with certainty.

Q How do I place a ship of a specific size?

A Follow these steps to place a ship of a specific size:

Check the black icons
Identify the size of the unplaced ships. Larger ships have fewer placement options, so prioritize them.
Narrow down possible spaces
Look for rows or columns where a ship of that size can fit. Spaces already occupied by other ships or water will make the placement options clearer.
Confirm partially placed ships
If part of a ship is already placed, extend it along the same line to complete the ship.

Q What should I do if I get stuck?

A Try the following steps if you get stuck:

Review
Recheck the numbers and black icons to ensure there are no unprocessed rows or columns.
Make a temporary placement
If unsure, make a temporary placement and proceed. This may reveal new information.
Fill around placed ships
Surround already placed ships with water to reveal other placement options.
Think backwards
When fewer ships remain, focus on the remaining empty spaces to identify where they fit.
