Battleships
Find the hidden fleet using row and column clues.
The rules
How to play
- 01
The fleet
Every puzzle hides a full fleet of ships. Place each one on the grid — the ship sizes vary with the grid you choose.
- 02
Straight lines only
Ships sit horizontally or vertically, never diagonally, and each is a single straight run of cells.
- 03
No touching
Ships never touch one another — not even at a corner. Keep at least one water cell between every ship.
- 04
Read the counts
The numbers along each row and column tell you exactly how many ship cells that line must contain.
- 05
Use the hints
Some cells start revealed as ship parts or water. Anchor your first deductions on those given cells.

Four ways to find the fleet
Start with extremes
Attack rows or columns marked 0 (all water) or with a high count (packed with ship cells) first.
Wall off with water
The moment you place a ship segment, mark water in every diagonal cell around it.
Complete the count
Once a row or column reaches its ship total, flood the remaining cells with water.
Find forced placements
Sometimes a ship can only fit one way given the constraints — place it and move on.
