Create a 'battleship' game

I would like a simple 'battleship'-style game, with the following features: 1. A default grid of 10x10, but with the option to change the grid. If the game is made in HTML, this could be done by simply identifying a variable which can be modified. 2. The ability to place a 5-long 'battleship' on the grid, which is not visible to players. 3. The ability to specify a space on the 'battleship' as special. 4. The ability to click squares on the grid and show an animation to indicate whether the 'battleship' has been hit, with a different animation if the 'special' space is hit. 5. The ability to reset the game at any point.
