Salvo
Quick Pitch
Salvo (Battleship on paper) is a two-player deduction game โ secretly place your ships on a grid, then take turns calling out coordinates to find and sink your opponent's fleet before they sink yours.
Hook
Both players draw two 10ร10 grids. On one, you arrange your ships secretly. On the other, you track what you've fired at and what you've hit. You take turns calling out a square โ your opponent says "Hit" or "Miss." A hit ship sinks when you've found every square it occupies, and your opponent announces "You sank my Battleship!" The game is pure deduction: narrow down probabilities, read the pattern of your hits, find the rest of the ship.
Equipment Needed
- Two sheets of paper per player (one for their fleet, one for opponent's fleet)
- Pencil or pen (multiple colors helpful for marking hits/misses)
- Optional: ruler for drawing straight grid lines
- Optional: separate sheets showing ship sizes for reference
Setup
Create Two Grids: Each player draws two 10ร10 grids
- Grid A: Shows player's own ships (hidden from opponent)
- Grid B: Shows opponent's ships (empty initially; filled as player fires)
Label the Grids:
- Columns labeled A-J (left to right)
- Rows labeled 1-10 (top to bottom)
- Coordinates are read as Letter+Number (e.g., A1, J10)
Standard Fleet:
- 1 Battleship (4 squares)
- 2 Cruisers (3 squares each)
- 3 Destroyers (2 squares each)
- 4 Submarines (1 square each)
- Total: 20 squares occupied
Place Ships: Each player secretly places their ships on their Fleet Grid (Grid A):
- Ships placed horizontally or vertically (not diagonally)
- Ships cannot touch each other (not even diagonally)
- Ships cannot overlap
- Both players must finish placement before firing begins
Example of ship placement (can mark ships as outlined squares):

Rules
Objective
Locate all opponent's ships and sink them (hit all squares of every ship) before opponent sinks your entire fleet.
Gameplay
- Turn Structure: Players alternate turns calling out one coordinate per turn
- Calling Shots: A player calls out a coordinate (e.g., "E5")
- Opponent's Response: The opponent checks their Fleet Grid and responds:
- HIT: If a ship occupies that square
- MISS: If no ship is there
- SUNK: If the shot was the final hit needed to sink that ship (then name the ship: "You sank my Battleship!")
- Recording: Each player marks shots on their Opponent Grid (Grid B):
- Mark hits with X or โ
- Mark misses with O or โข
- Continuing Play: Players continue taking turns until one player sinks all opponent ships
Sinking a Ship
A ship is sunk when a player has hit all squares of that ship. The player sinking it announces which ship was sunk. Only fully sunk ships are confirmed.
Winning
The first player to sink all ships in opponent's fleet wins the game.

Tips
Searching Phase (Early Game):
- Use a "search pattern" to efficiently scan the grid
- Checkerboard pattern: Hit every other square systematically (A1, A3, A5, C1, C3, etc.)
- This pattern guarantees hitting any ship of size 2 or larger
- Typical search spacing is 2-4 squares apart
Attacking Phase (Mid-Game):
- Once you achieve a hit, concentrate shots around that area
- Try to determine ship orientation (horizontal vs. vertical)
- Focus fire on adjacent squares
- Common patterns: Try all four adjacent squares first before expanding outward
Probability Considerations:
- Ships occupy larger areas in the middle of the grid
- Concentrating early searches on central areas increases hit probability
- Avoid clustering your own ships in one area (makes you vulnerable to luck)
Deduction Strategy:
- If you hit a 3-square ship, determine if it's horizontal or vertical
- Once sunk, know that ship's length helps identify others
- Track which ship sizes remain to narrow down hit patterns
- Large ships (Battleship, Cruisers) cluster hits more when sunk
Placement Strategy:
- Spread ships throughout the entire grid
- Don't cluster ships together
- Place ships unpredictably (mix edge and center positions)
- Some players deliberately avoid obvious patterns
Mental Patterns:
- Avoid symmetric or obvious patterns in ship placement
- Many beginners place ships in lines or corners โ avoid this
- Some players place large ships far apart; others cluster them
- Vary your own strategy from game to game
Variations
- Varied Fleet Sizes: Agree on different ship counts/sizes before game starts
- Blind Salvo: Call three coordinates per turn instead of one (faster, harder)
- Salvo Rules: If opponent hasn't sunk your ship, they don't know until it's fully sunk
- Rectangular Grids: Use 8ร8, 12ร12, or other grid sizes
- Line of Sight: Some variants require ships to remain "visible" from edges
- Cooperative Version: Players work together to find and sink "dummy" opponents' fleets
- Three-Player: Use three grids, three players
- Speed Battleship: Use smaller fleets (3-5 ships) for faster games

History & Origins
Battleship originated as a pencil-and-paper game in the 1930s-1940s, with various versions emerging independently in different countries. The game was first published commercially in 1931 in the form "Naval Combat" and later trademarked as "Battleship" when released by Milton Bradley in 1967. The paper version predates all commercial board game versions and remains popular alongside them.
Cultural Context
Battleship exemplifies the appeal of deduction games โ combining chance (where opponent places ships), strategy (where you place yours and search pattern), and probability (calculating likely positions). The game has transcended its paper origins, becoming a major commercial board game and even a film franchise, yet the paper version remains engaging and accessible.
The game teaches spatial reasoning, strategic thinking, probability assessment, and patient deduction. Many schools use it in mathematics education to teach grids, coordinates, and probability concepts.
