keep convoys
The aim is to destroy all the ships of the computer before it
destroyes your ships. After placing your own convoys on the left board,
you can shoot by clicking on the fields in the right board.
If you shoot at clear water, it will be indicated by a wave in the field
and a message. When you find a ship, it shows up
and the message 'You hit a convoy' appears.
When you find the last ship of a convoy, all ships of the convoy will
be shot and empty fields which are so close to the convoy
that no other could be there will be marked with a single wave
. You can also set such markings yourself to prevent
you from firing at fields where no convoy could be.
At the end of the game, a message shows who won with how many torpedos.
In case you lost, the PC will also show you the ships
which you did not find.
