Sea War – Free Online Battleship Game
A strategic battleship game in the browser: place your ships, read the radar and sink the opposing fleet against the computer or a friend.
Play nowHow to play
Place your ships on the grid, then choose where to strike using the radar and the memory of earlier shots. You can face the CPU for a quick match or challenge a friend. Sea War takes classic battleship logic into the browser, with a board that works on PC and smartphone.
Who it is for
Sea War is for anyone who wants a full battleship match in the browser, against the CPU or a friend, with radar and fleet placement.
Place the ships, then fire. Radar helps you read the board; the memory of earlier shots stays yours. Against the CPU you get a practice match. Against a friend it is the same grid and the same rules. It is not a real-time naval shooter.
The battleship rules guide on the site explains hunt, target and the mistakes that stretch a match. Open it if you are playing for the first time or if the table (paper or screen) disagrees about touching ships.
What you get
- Full battleship match in the browser
- Play against the computer or a rival
- Radar and fleet placement
- No download, play immediately
