How to play Sea Battle with Gather
Sea Battle is for two players, each with their own phone – you don’t need a TV. On your own, you play against the computer.
Set up a game
Without a TV: in the Gather app, under “Play without a TV”, choose “Sea Battle”, then “Play the computer” or “Invite friends (2–6)” – your opponent joins with the code on the same Wi-Fi. With an Apple TV, iPad or Mac: choose the game, “With your phones” or “With computer opponents”, then “Open a room”.
Tap Ready
Both players tap “Ready” in the lobby. Since Sea Battle is for exactly two, the game starts straight away.
Place your fleet
Your phone says “Place your fleet”, and a random layout is already there. Tap and drag a ship, turn it with “Rotate”, or reshuffle everything with “Random placement”. If a ship doesn’t fit, you’ll see “No room there.”
Confirm
“Done” locks in your layout. While your opponent is still placing ships, you can reopen it with “Change”.
Aim and fire
At the top you see “…’s waters” with your shots, below that “Your fleet”. On your turn, tap a cell and press “Fire!”. After a hit the phone says “go again!” and you keep shooting.
Follow your opponent
While your opponent aims, your phone shows “… is aiming …” and then where they fired and whether they hit or sank one of your ships.
Finish and rematch
Once a fleet is sunk, all ships are revealed. “Play again” starts a new game, “Leave room” ends it for you.
With or without a TV
Without a TV, the iPhone you set the game up on becomes the host and shows you the same view as your opponent. Anyone without the app enters the code in a browser – the controls are the same there.
With an Apple TV, iPad or Mac, the big screen shows both waters with every shot, hit and sunk ship, but no ship positions – only the owner sees those on their phone. The TV reveals everything only once the game is over.
