Sea Battle — About this game
Sea Battle turns a hidden fleet into a deduction contest across a grid. Place ships of different lengths, then call a coordinate and read the answer before deciding where the next shot should go. A hit is a clue to the rest of a vessel rather than a reason to fire randomly nearby. Standard battles keep the familiar search-and-sink rhythm, while other modes add ships with different attack patterns. Protect the arrangement of your own fleet as carefully as you narrow the possible locations of the enemy's last ship.
