Excuse for any grammar mistakes.

In this game you are going to sink submarines in the Swedish
archipelago.

All the subs exists in a 10x10 square.

You move your ship with the arrow keys (Up down left right) and drop bombs
with enter. On the left part of the screen you can watch the distances to
the subs and in the upper right corner your current position.

The * in the figure below is your ship and the numbers symbolizes 
the distances to the subs. 

The numbers aren't there in the game we just plotted them here 
so it shouldn't be so hard to explain.

   To start the game

   4:
   3:
   2:
   1: number off subs        2-8

   Then press U137

   Play the game

   4:
   3:
   2:      Moves:10
   1: Submarines: 3


You have four difficulty levels 

  1:   The subs light up after you have dropped a bomb. And they
       are still at that position the next move.
       Flag 59 set 
       Flag 60 Clear 
       (This is a very easy level)

  2:   The subs don't light up and they are lying still.
       Flag 59 Clear
       Flag 60 Clear

  3:   The subs light up and they are moving around.
       Flag 59 Set
       Flag 60 Set

  4:   The subs don't light up and they are moving around.
       Flag 59 Clear
       Flag 60 Set

You must set and clear the flags by your self.

Background:

  Why did we call the game U137, if you think hard you might remember 
  a Russian submarine named U137 that drove up on SWEDISH land an night in
  the early 80's . The Russians got there sub back and the swedish marine
  got more money, but we still have Unidentified underwater activity in our
  territorial water, as it so nicely is called.
