Sea Battle, also known as Battleship, is a classic board game for two players that simulates a battle between two big fleets on the ocean. It's a popular guessing game that is often played with pencil and paper. The game is played on four boards, two for each player, and each board is square and has a dimension of 10x10 cells. The objective of the game is to destroy the opponent's fleet by taking turns shooting at the opponent's board.

Before the game begins, each player secretly arranges their ships on their primary board. Each ship occupies a number of consecutive cells on the board, arranged either horizontally or vertically. The game has four types of ships and six types of weapons. After the ships have been positioned and the weapons have been equipped, the game proceeds in a series of turns. The game offers both single and online multiplayer modes, allowing players to play with their friends or other opponents from around the world. In addition, the game features cool doodle graphics, a global leaderboard, and achievements to unlock.
