Battleship server is online on http://battle.codes/

This is a very stupid battleship robot. It will always place ships the same place and shoot random at the enemy.

Battleship game

Rules

The boards are 12 x 12 squares

In planning mode the player needs to place 6 ships.

• 1 ship with length of 2 squares.
• 2 ships with length of 3 squares.
• 2 ships with length of 4 squares.
• 1 ship with length of 5 squares.

In playing mode, each player shoots at the enemy (the other player) board. When shooting at the enemy, one of three things might happen.

1. Splash - You missed an enemy ship.
2. Pang! - You hit an enemy ship.
3. Sunk! - You hit and sink an enemy ship

The player that sinks all the enemy ships first, wins the game.
