What is Fleet Strike?
Fleet Strike is a one-player sea battle played across two 10x10 grids. You position five ships of different lengths on your grid, then swap shots with the computer at squares you cannot see on the opposing grid. The first player to sink all five enemy ships wins the battle.

Fleet Strike is a naval hide-and-seek game against a computer that does not guess blindly. You tuck five ships into your own patch of ocean, then the two of you trade shots one at a time until one fleet is at the bottom of the ocean. What makes it tense is the opponent: it keeps a live probability map of your possible ship positions and always shoots where a ship is likeliest to sit. Based on Bill Mei’s open-source Battleboat.js, it plays unblocked in your browser and remembers your record between visits.
Setting Up and Firing
Deploy your fleet. The left grid, Your Fleet, is where your ships go. Choose a ship in the list, set its direction with Rotate Ship, then click the square where it should start. A preview shows where it will sit. Ships may not overlap or run off the edge. The five ships are:
- Aircraft Carrier, 5 squares
- Cruiser, 4 squares
- Destroyer, 3 squares
- Submarine, 3 squares
- Patrol Boat, 2 squares
When all five are placed, press Start Game.
Take your shots. Click a target on the right-hand Enemy Fleet board. Misses are marked with an X on white, hits glow red, and a ship goes down once all of its squares are struck. The computer returns fire after every shot you take, and its results appear on your grid. Sink all five enemy ships before it sinks yours.

Hunting Smarter Than the Computer
Think of every game as two phases, searching and finishing.
While searching, shoot in a checkerboard pattern. The smallest ship covers two squares, so it must touch at least one square of every alternating pair. You cover the whole sea with half the shots.
When you get a hit, switch to finishing mode. Try the four squares around it. Once a second hit appears, keep shooting along that line in both directions until the ship sinks.
When placing your own fleet, avoid patterns. The computer’s first volley leans toward a pair of opposite corners and the cells beside the remaining two, so a ship jammed into a corner tends to be found early. Mix horizontal and vertical ships and leave space between them, so finding one does not give away a neighbor.
Use the sunk information. Once the big ships are gone, gaps of one or two squares cannot hide anything larger than what remains.
How It Stacks Up
Most grid-guessing games online give you a random-shooting opponent that is easy to beat. This one makes you earn every win, which keeps the Stats panel honest: wins and hit percentage are tracked so you can see if your searching is getting tighter. It plays best on a laptop or a tablet, where both grids have room.
If you like deduction games, Bulls and Cows is another clean logic duel, and Logic Mines asks you to read a hidden grid from number clues.
Fleet Strike: questions players ask
Is Fleet Strike like the old pencil-and-paper ship game?
Yes, it follows the same idea of hiding ships on a grid and calling shots, with five ships per side on a 10x10 board. It is its own open-source game, built by Bill Mei, with a probability-driven computer opponent.
Why does the computer find my ships so fast?
It checks every untouched square and counts how many placements of your surviving ships would cover it, then aims at the square with the highest count. After a hit, nearby squares jump in value, so it closes in quickly. Its first shots also lean toward a fixed opening pattern.
Can I put ships diagonally or touching each other?
Ships must lie horizontally or vertically, never on a slant, and they cannot overlap or stick out past the edge. Touching is allowed, but spacing them out makes it harder for one lucky run of hits to find two ships.
Where can I see my win record in Fleet Strike?
The Stats panel shows how many games you have won out of those played and your shot accuracy. It is stored in your browser and updates when a new game starts. Reset Stats clears it.
Does Fleet Strike work on phones?
Taps work, but the two grids are shrunk to sit next to each other, so each square is tiny on a phone held upright. Turning the phone sideways and going full screen helps, and a tablet or laptop is easier still.
