Sink all five of your opponent’s ships, which means hitting all 17 of their cells. The game ends the moment the last cell is hit.
You win by sinking your opponent’s whole fleet before they sink yours. That is five ships and 17 cells, and the game ends the instant the last cell is hit, with no extra turn for the other player.
Counting the race
Both players need 17 hits, taking one shot per turn, and Azure fires first. The player who finds ships in fewer shots gets there first, so how you search matters more than luck. A hit does not give a second shot (another shot after a hit).
