About Ships Finder

A classic Battleship Solitaire logic puzzle. Use row and column number clues to find the hidden fleet across 30 handcrafted levels from 6x6 Beginner to 10x10 Master.

Description provided by GameZipper.

How to play

1. Numbers along the top and left show ship-cell counts per column and row. Zero means the whole row or column is water.
2. If a row or column shows 0, mark every cell in it as water. This shrinks the search space immediately.
3. Ships never touch, not even diagonally. Once you place a ship, all 8 surrounding cells are water.
4. Count how many of each ship length you still need. A 4-cell line is a battleship; a single cell is a submarine.
5. When your marks match every clue and the fleet is complete, press Check to verify and win.

Controls

This game supports touch, keyboard, mouse input; the exact controls are explained inside the game.

Questions

How do you play Ships Finder?

Each row and column shows how many ship cells it contains. Mark cells as ship or water using these clues, the fleet composition (how many ships of each size), and the rule that ships never touch — not even diagonally. When every ship is placed correctly you win.

What is Battleship Solitaire?

Battleship Solitaire (also called Battleships, Shipfind, or Yubotu) is a single-player logic puzzle invented in the 1980s. Unlike the two-player Battleship board game, here you deduce the entire fleet's location from number clues — no guessing, no shooting.

What are the rules of Ships Finder?

(1) The numbers around the grid tell you how many ship cells are in that row or column. (2) The fleet composition is shown — for example 1 battleship (4 cells), 2 cruisers (3 cells each), 3 destroyers (2 cells), and 4 submarines (1 cell). (3) Ships may never touch each other, not even diagonally. (4) Every ship is either horizontal or vertical — never diagonal.
