How to Play
Sea Battle is the grid guessing game. Your fleet is laid out for you and the enemy's is laid out for them, and you trade shots — against the CPU or a friend on the same device — marking hits and misses until one fleet is sunk. Both fleets are placed for you at the start — five ships of 5, 4, 3, 3 and 2 on an 8x8 grid, seventeen squares a side — so there is no setup phase to sit through and the game opens on the first shot. Your record is kept per device.

Tips & Tricks
- 1Hard fires on a parity grid, only at squares where x plus y is even. The shortest ship is two squares long, so it always covers one even and one odd square — a parity sweep cannot slip between its squares.
- 2The CPU hunts after every hit: it queues the four neighbours of a hit square and works through them before going back to searching, so a hit near the edge is worth less to it than one in open water.
- 3The 5-length ship has only four possible horizontal starting columns on an 8-wide row, and four vertical ones down a column — once you have a rough idea where it lies, the search collapses.
- 4Seventeen squares hold the whole fleet on sixty-four, so a shot that hits nothing is information: it eliminates the squares the remaining ships could have spanned.
Frequently Asked Questions
Can I place my own ships?
No — both fleets are laid out randomly when the round loads, with no overlap, and there is no setup screen. The game is about deduction from the first shot rather than about hiding your fleet.
What do the three difficulties change?
Hard adds a parity sweep: instead of firing at random empty squares it works through the grid where x plus y is even, which guarantees contact with any ship of two squares or more. Easy and medium search at random; every difficulty chases neighbours after a hit.
Can I play on my phone?
Yes. Firing is a single tap on an enemy square and the 8x8 grid scales to the width of the screen, so each cell is a comfortable target. No keyboard is needed at any point.
