Bship

## Description

In this _Battleship_ variant, the player fights against the AI. The player may
place four ships of two, three, four and five tiles large. Ships can be placed
both horizontally, vertically and diagonally on the grid.

Instead of only one shot each turn, players receive a number of shots
depending on the ships left. Some ships count for more shots than others. Only
once the player has fired all shots is he or she notified of hits and misses,
so that the player does not know which shots were the hits. The player wins if
he or she manages to sink all enemy ships for the AI does the same.
