How this version works
Each player privately shuffles and locks a fleet, then gets two views on every turn: your own waters with incoming shots, and a separate target grid. Fire once, then pass the device behind the privacy screen.

Hidden Fleet
Two hidden fleets, sixty-four squares, and the dangerous confidence of calling B4.
Blue, this is your fleet.
Shuffle until you like the layout. The other player will never see this screen.

Your waters
Target grid
The classic paper version
On paper, each player secretly draws ships onto a coordinate grid and keeps a second grid for shots. The printable version gives you both grids.
Search in a pattern
Instead of firing at random, leave gaps between early shots. Once you find a hit, search adjacent squares until the ship is sunk.
A little more
A proper one-device version
Each player has private waters and a separate target grid. The pass screen hides the board between turns, so two people can play on one phone or tablet without seeing the other fleet.
