Few games capture the pure tension of hidden information like Battleship. You’re staring at a blank grid, calling out coordinates into the void, trying to locate your opponent’s fleet before they find yours. Whether you’re teaching a child the basics or brushing up on the rules before a rematch, this complete guide covers everything you need to know — including the strategies that will actually help you win.
Quick Answer: Battleship is a 2-player game where each player secretly places 5 ships on a grid, then takes turns calling out coordinates to find and sink the opponent’s fleet. The first player to sink all 5 enemy ships wins. Ships cannot be moved once placed.
What Is Battleship? A Brief History
Battleship has roots going back to World War I, when soldiers played a paper-and-pencil version to pass the time. Milton Bradley first published the plastic board game version in 1967, and it’s now produced by Hasbro. Despite decades of video game adaptations and electronic versions, the classic plastic board game remains a staple of family game nights around the world.
The game is elegantly simple in concept: you have a fleet, your opponent has a fleet, and neither of you can see the other’s board. Everything hangs on deduction, pattern recognition, and a little luck.

What’s in the Battleship Box?
The classic Battleship set includes:
- 2 ocean grid units (each with an upper and lower grid)
- 5 ships per player (10 ships total)
- Red “hit” pegs (80 total)
- White “miss” pegs (168 total)
The Five Ships and Their Sizes
Each player receives the same five ships:
| Ship | Grid Spaces (Holes) |
|---|---|
| Carrier | 5 |
| Battleship | 4 |
| Cruiser | 3 |
| Submarine | 3 |
| Destroyer | 2 |
In total, your fleet covers 17 out of 100 grid squares — meaning 83% of the board is open water. This is why early guessing feels like searching in the dark.
Battleship Setup: How to Place Your Ships
Set up your game board so your opponent cannot see your ocean grid (lower portion). Place your 5 ships on the grid according to these rules:
- Ships must be placed horizontally or vertically — never diagonally
- Ships cannot hang off the edge of the grid
- Ships can touch each other, but they cannot share a grid space
- Once the game begins, you cannot move your ships
Anchor each ship by pressing the pegs into the grid holes along the ship’s length. Take time with placement — this is your most important decision in the entire game.
How to Play Battleship: Basic Rules
Taking Turns
Players take turns firing shots. On your turn:
- Call out a coordinate — a letter (column) and a number (row). For example: “B-7”
- Your opponent checks that spot on their ocean grid and responds with either “Miss” or “Hit”
- Mark the result on your target grid (upper portion):
- White peg: Miss
- Red peg: Hit
- If you score a hit, your opponent also places a red peg in the corresponding hole on their ship
Then your opponent takes their turn, following the same process.
Announcing Sunk Ships
When every hole in one of your ships has a red peg, that ship is sunk. You must announce which ship was sunk: “You sunk my battleship!” — or whichever ship it was. This gives your opponent useful information about your fleet’s positioning, so note that sinkings are required to announce but can inform enemy strategy.
Winning the Game
The first player to sink all five of their opponent’s ships wins. There are no draws in standard Battleship.
Battleship Grid Reference
The standard Battleship grid is 10×10 squares. Columns are labeled A through J (left to right) and rows are numbered 1 through 10 (top to bottom). A coordinate like “E-5” refers to column E, row 5.
This gives 100 possible shot coordinates in a game. Since the fleet covers 17 squares, you need to hit those 17 specific squares to win — while your opponent is doing the same to you.
Advanced Variant: Salvo Rules
The Salvo variant makes the game faster and more tactical. Here’s how it differs from the standard game:
- On your first turn, you call out 5 shots simultaneously, marking each with a white peg on your target grid
- After calling all 5 shots, your opponent announces which were hits and which ships were hit
- Update your target grid: change hit pegs from white to red
- Continue alternating turns — but each time one of your ships is sunk, you lose one shot from your salvo. Start with 5; lose one per sunken ship
- Continue until one player sinks the entire opposing fleet
Salvo rewards players who can track multiple simultaneous hit patterns and think ahead about probability. In my experience, it changes the feel of the game significantly — there’s much less waiting between meaningful information.
Paper and Pencil Battleship
No physical game set? You can play Battleship with paper and a pencil:
- Each player draws two 10×10 grids on paper
- Label columns A–J and rows 1–10
- Place your ships by shading in the corresponding squares on your “ocean” grid
- Use “X” for hits and “O” for misses on your “target” grid
For a harder version, increase the grid size — a 15×15 or 20×20 board makes ships much harder to locate.
Battleship Strategy: How to Win
Battleship isn’t purely about luck — players who understand probability and pattern recognition win more often. Here are the strategies that actually work:
Ship Placement Strategy
- Avoid the edges and corners. Most players instinctively start shooting along edges. Placing ships toward the center means they take longer to find.
- Don’t cluster your ships. If ships are grouped, one hunt-and-destroy sequence can sink two. Spread them out across different quadrants.
- Vary your orientation. Mix horizontal and vertical ships. Predictable alignment patterns are easier for experienced players to exploit.
- Don’t place ships perfectly adjacent. Even though the rules allow it, touching ships can be found faster once one is targeted.
Shooting Strategy
- Use a checkerboard pattern. Since the smallest ship (Destroyer) covers 2 squares, you only need to hit every other square to guarantee you’ll eventually hit something. Shooting in a diagonal checker pattern covers the board efficiently.
- After a hit, shoot adjacent squares. When you score a hit, focus your next shots on the squares directly above, below, left, and right to determine ship orientation.
- Once you know direction, keep going. If two hits in a row reveal the ship is horizontal, continue along that row until the ship sinks before switching strategy.
- Count remaining ship sizes. Your opponent announces when a ship sinks, so you always know which ships are still afloat. Use this to prioritize your hunt and avoid wasting shots on areas too small for remaining ships.
Common Mistakes to Avoid
- Shooting randomly after a miss. Random shots waste turns. Maintain a systematic pattern to maximize information per shot.
- Forgetting to track opponent announcements. When your opponent sinks one of your ships, they now know a section of your board. Be mindful of what they’ve learned.
- Placing ships on the same spots every game. If you play with the same person repeatedly, predictable placement becomes a liability. Vary your setup.
- Abandoning a hit too early. New players sometimes abandon a hit square and move on. Always follow up on confirmed hits immediately — they’re too valuable to leave.
- Placing the Destroyer in a corner. Corners are the most predictable location for small ships. Many experienced players check corners early.
Battleship Variations and House Rules
Battleship has inspired dozens of variations over the years. Some popular house rules include:
- No-repeat shots: Standard rule — you can’t call the same coordinate twice. Worth confirming before you start.
- Expanded fleet: Add more ships or allow players to choose their own number of ships for an asymmetric challenge.
- Simultaneous shooting: Both players call shots at the same time before revealing results — speeds up the game significantly.
- Larger grid: A 15×15 or 20×20 grid makes the game considerably harder and longer.

Frequently Asked Questions
Can ships touch each other in Battleship?
Yes, ships are allowed to touch (occupy adjacent squares) in the official rules. However, they cannot share the same square. Many players choose to house-rule that ships must have at least one space between them — just agree before the game starts.
Do you have to announce which ship was hit (not just sunk)?
In the official rules, you only announce when a ship is completely sunk, and you must announce which specific ship it was. You do not have to reveal which ship a hit landed on until the entire ship is sunk.
What happens if you call a coordinate you already called?
In standard rules, you can’t legally call a coordinate twice. It’s a wasted turn. Good players mark every shot (hit or miss) to avoid repeating. If you accidentally repeat a shot, most players allow a redo.
Can you play Battleship with more than 2 people?
The classic game is designed for exactly 2 players. For multiplayer variations, some house rules use multiple grids in a tournament-style bracket, or modified rules where players rotate targets.
Is there a strategy that always wins?
No guaranteed winning strategy exists since ship placement is hidden and random. However, the checkerboard search pattern combined with systematic follow-up on hits gives you a significant mathematical edge over purely random play.
Wrapping Up
Battleship is one of those rare games that teaches deductive reasoning without feeling like a lesson. Every missed shot gives you information; every hit accelerates your hunt. Once you understand the probability behind the checkerboard pattern and learn to read the board systematically, you’ll find yourself winning far more often than luck alone would predict.
The beauty of Battleship is that it takes minutes to learn but rewards players who think carefully about placement and pattern. Set up your fleet wisely, and you might just hear that satisfying phrase from across the table: “You sunk my battleship!”
