Everything families need to set up, play and win at Battleships, from pencil-and-paper grids to why the game quietly builds brilliant young minds.
Battleships is a two-player guessing and strategy game in which each player secretly places a fleet of ships on a lettered and numbered grid, then takes turns calling out coordinates in an attempt to locate and sink the opponent's vessels before their own fleet is destroyed. To win, you simply need to sink every one of your opponent's ships first, by correctly guessing all the squares each one occupies. The rules are straightforward enough to learn in under five minutes, yet the game offers enough tactical depth to hold a child's attention for years.
The classic pencil-and-paper version requires nothing more than two sheets of squared paper, two pencils and a flat surface between players, with a book or box propped up as a screen. Each player draws two ten-by-ten grids, labels the columns A through J and the rows 1 through 10, and the game is ready to begin. A commercial or wooden board edition replaces the paper with peg boards and ships, making setup faster and the experience more tactile, but the core rules remain exactly the same.
Each player needs two grids on their sheet: one labelled "My Fleet" (where you mark your own ships and track incoming shots) and one labelled "Enemy Waters" (where you record your own guesses and their results). Columns run left to right and are labelled A to J. Rows run top to bottom and are numbered 1 to 10. Every square is therefore identified by a letter-number combination, such as B4 or G7. Keep your sheet hidden from your opponent throughout the game.
The standard fleet for two players consists of five ships of different lengths. The Carrier occupies five squares, the Battleship four, the Cruiser three, the Submarine three and the Destroyer two. Each ship is placed horizontally or vertically on the "My Fleet" grid, never diagonally. Ships may not overlap one another or extend beyond the edge of the grid. Players place all ships before the first turn is called and may not move them once play begins.
A useful tip for younger players: draw a small outline of each ship beside the grid and cross it off once all squares have been placed. This prevents the common beginner error of forgetting how long a particular ship is supposed to be.
Research note · Spatial reasoning and grids
Adele Diamond's work on executive function highlights that activities requiring children to hold hidden information in mind whilst planning future moves, precisely what Battleships demands, strengthen working memory and inhibitory control, two of the most reliable predictors of later academic success. Even marking a coordinate on a grid exercises the same mental muscles children use in early mathematics.
Decide who goes first with a coin toss or by letting the younger player begin. The first player calls out a coordinate, for example "C6". The opponent checks their "My Fleet" grid: if C6 contains part of a ship, they say "Hit"; if the square is empty, they say "Miss". The calling player marks the result on their "Enemy Waters" grid, using one symbol for a hit and another for a miss. Players then swap turns.
When every square of a ship has been hit, the owner must announce which vessel has been sunk: "You've sunk my Battleship." This announcement is not merely good sportsmanship; it gives the attacking player crucial information about how many ships remain and helps younger children stay engaged with the progress of the game.
The game ends the moment one player's entire fleet has been sunk. The player whose ships survive wins. For families who prefer a more structured scoring system, you can award one point per hit across a series of games and keep a running tally, which introduces a satisfying mathematical element and gives children who lose a round a reason to stay motivated.
Whilst the pencil-and-paper format has real charm, a physical board edition offers several practical advantages for families with young children. Pegs or wooden pieces provide a tactile confirmation of hits and misses that small fingers find genuinely satisfying. There is no risk of accidentally glimpsing a sibling's pencil marks through thin paper, and nothing needs to be drawn afresh for each game. A well-made set also travels reliably, making it a dependable companion for car journeys, holidays and rainy afternoons at a grandparent's house.

Kathy Hirsh-Pasek and Roberta Golinkoff, leading researchers in children's learning through play, argue that guided play, structured enough to have goals but open enough to preserve a child's sense of agency, produces measurably better outcomes in language, mathematics and social cognition than either passive instruction or purely free play. Battleships sits precisely in that productive middle ground.
Behind the pleasure of calling "Hit!" lies a quietly serious curriculum. Reading coordinates aligns letters with numbers, reinforcing the grid literacy children encounter in early map work and mathematics. Tracking which squares have already been guessed develops systematic thinking and simple probability awareness. Managing the disappointment of a miss, and the excitement of a hit, builds emotional regulation. Vygotsky's concept of the zone of proximal development reminds us that children grow most when a task is just challenging enough to require effort but not so hard as to cause frustration. Battleships, adjusted by grid size or fleet composition, can be tuned to sit in exactly that zone for almost any child between five and twelve.
Jeffrey Trawick-Smith's research on play quality similarly finds that games with clear rules, a social partner and a meaningful goal, three qualities Battleships possesses in abundance, rank among the most developmentally rich activities available to young children. The game asks players to remember, plan, deduce and communicate, often all within a single turn.
Research note · Turn-taking and self-regulation
Stuart Brown's research on play documents that rule-governed games, particularly those requiring players to wait, observe and then act, are among the most effective natural environments for developing self-regulation in children. The discipline of waiting for your opponent's call, and of answering honestly when your ship is hit, are small but genuine exercises in character.
Jaques of London has been making and selling games for families since 1795, longer than any other games company in the world. The range includes traditional games of every kind, from those that travel easily in a coat pocket to those that become the centrepiece of a family games night. Each is made with the same conviction that has guided the company for over two centuries: that well-made games, played together, are one of the finest gifts a childhood can receive.

Reduce the grid to six by six, use two or three ships rather than five, and play alongside your child rather than against them for the first session. The coordinate system, a letter paired with a number, is within reach for children who know their alphabet and can count to ten, and the game itself provides a motivating reason to practise both. Many families find that Battleships becomes a reliable favourite by the time a child is six, and continues to grow with them well into the primary school years.
In the pencil-and-paper version, a hardback book or a cereal box standing upright between players works well as a screen. A physical board edition with its own built-in divider removes the problem entirely, which is one of the most practical arguments for investing in a manufactured set. If peeking does happen, treat it gently as an opportunity to talk about honesty and the fact that a game only works when both players play fairly. Children under six sometimes peek simply because they have not yet fully grasped that hidden information is essential to the game's structure; a short explanation usually resolves it.
There is good reason to think so. Reading and calling coordinates practises letter recognition and number sequencing simultaneously. Tracking which squares have been tried and reasoning about which remain is an early form of systematic thinking and informal probability. Dana Suskind's research on the importance of rich cognitive input in early childhood, and Hirsh-Pasek and Golinkoff's work on playful learning, both support the idea that games which require children to think, communicate and plan produce genuine academic benefits. Battleships is not a maths lesson in disguise, but it exercises the same mental habits that make maths lessons easier.
On a standard ten-by-ten grid with five ships, a game between two adults typically lasts twenty to thirty minutes. With young children, the pace tends to be slower in the early rounds as coordinates are found and marked, so allow thirty to forty-five minutes for a first game and expect it to get considerably faster as children gain confidence. If time is short, the reduced six-by-six grid version usually concludes in ten to fifteen minutes, making it a practical choice for the gap before dinner or the last half-hour before bedtime.
