How to play
The goal
Battleship is a two-player game of hidden fleets on a 10×10 grid. Each player secretly places a fleet, then players take turns firing at coordinates, trying to find and sink every enemy ship first.
Placing your fleet
Playza's default is the Russian Морской бой fleet: one 4-cell ship, two 3-cell, three 2-cell and four 1-cell ships. Ships are placed in straight lines and may NOT touch each other — not even at a corner — so there is always at least one empty cell around every ship.
Firing and winning
Call a shot: a miss passes the turn; a hit lets you shoot again. When a ship's last cell is hit it is sunk, and the cells around it are automatically revealed as empty. Sink all ten enemy ships to win. The board is server-authoritative, so the opponent's ships are never revealed early.
Frequently asked questions
- What are the rules of Russian Battleship (Морской бой)?
- On a 10×10 grid each player hides ten ships (1×4, 2×3, 3×2, 4×1). Ships can't touch, even diagonally. A hit means you fire again; a miss passes the turn; sinking a ship auto-marks the surrounding cells as empty. First to sink the whole enemy fleet wins.
- Can ships touch in Battleship on Playza?
- No — in the default Russian ruleset ships may not touch, not even at the corners. The placement screen blocks any illegal position, and the AI follows the same rule.
- What happens when you sink a ship?
- All cells around the sunk ship are automatically revealed as misses, because no other ship can be next to it. You also keep your turn after a hit or a sink.
