A fleet of ships is hidden in the sea. You know the fleet — for example one 4-square ship, two of 3, three of 2 and four single squares — and how many ship squares are in each row and column.
Ships lie in straight lines across or down, and no two ships touch, not even at a corner. Some puzzles show a few pieces to start you off: an end piece shows which way its ship continues.
Start with rows and columns of 0, then lines that are full, and remember every ship square has water at its corners.
Place the whole fleet so that each row and column has the right number of ship squares, with no ships touching.
The full guide, with a worked example and common mistakes: How to play Fleet Finder.
The ships to find, from the longest down to single squares. Ships you’ve completed turn green.
Yes — every puzzle here is checked to have exactly one solution.
A rounded end shows the ship continues the other way; a middle piece has ship on both sides; a circle is a one-square ship.
Open the Fleet Finder Solver, type the counts, mark any shown squares and press Solve.
