Battleships Calculator

This calculator uses the possible placements of the ships to determine where most ships would overlap thus giving a heatmap of viable strike options. Click on a cell to mark it as a MISS, HIT or SUNK. A miss constitutes a cell that has no ships going through it, a hit is a cell that can't have neighbours on the diagonals and a sunken cell doesn't have neighbours at all. All of the above is accounted when calculating the chances.
