Sea Battle

Sea Battle is an adaptation of the Battleship board game. It can be played against a computer opponent with three difficulty levels, locally by passing on the device, using Bluetooth or using an internet connection. Players place ten ships on a 10x10 board. They each take up one square in width, but have different lengths: 1x4, 2x3, 3x2 and 4x1. Ships can be placed along the borders but not next to each other, also not touching diagonally. After setting up the placement, players take turns firing shots to destroy the enemy ships. Missed shots are marked on the board and hits show up as a red cross. When a hit is scored another turn is provided right away. When all parts of a ship are destroyed, the ship is revealed along with all surrounding squares. The first player to destroy all enemy ships, wins the game.

Ships can be placed and rotated manually, but there is an 'auto' function as well to let the computer do the placement. Next to the classic mode the game supports an advanced version of the concept. The basic rules are identical, but it adds two types of fighter planes, a radar, anti aircraft guns, nukes and mines. Instead of firing regularly, players can use these units to advance more quickly. Planes can bomb an entire row or a square radius, the radar scans a certain area revealing ships, AA guns can bring down incoming enemy planes, nukes destroy everything in a radius and mines blow up when targeted, revealing the same square on the field of the player who initiated the attack. Each unit has a cost and only a limited amount of money is provided. Units are bought before starting a match, but can then be used at any moment. The position of AA guns needs to be assigned to a certain row before starting the game. Next to points, the winners earn money to bring it to the next battle.

The game is free-to-play with advertisements, but no in-app purchases. The game uses a hand drawn, blue pen style that is used in many other Byril games.
