Sea Battle rules at a glance
Each player secretly places five ships (5, 4, 3, 3 and 2 squares long) on a 10×10 sea. Then you take turns firing at one square of the enemy sea. Each shot is a hit or a miss, and when every square of a ship is hit it is sunk and revealed. Sink the whole enemy fleet first to win.

FAQ
May ships touch each other?
You choose when creating a room. With “touching allowed” ships may lie side by side; with “keep apart” they may not be neighbours, even diagonally.
Do I shoot again after a hit?
By default players alternate single shots. Choose “fire again on a hit” to keep firing for as long as you hit.
Can I play without an account?
Yes. Games against the AI and pass-and-play on one device need no sign-in; in pass-and-play a “pass the device” screen hides each fleet between turns. Online matches and rankings need a GameNow account.
How do I play with a friend?
Tap “Invite a friend” to create a room with a code and link. When your friend opens the link they join instantly, and the game starts as soon as both players are in.
Is there a time limit?
Online games allow 45 seconds for placement and for each shot. If placement time runs out your fleet is placed at random; if a shot times out, one unfired square is chosen for you.
