Control Buttons

Since the game is played by 
making moves it is necessary
to know how to make a move:
  1. first You need to select
     a checker, which will move,
  2. then You make the move.

Selection of Checker:
Checkers are selected by 
pressing 4 and 6 buttons. 
Selected checker is marked by
green circle around it. It is 
only available to select those 
checkers, which can make a valid 
move.

Completion of Move:
Move is made by pressing one of
these buttons: 1,3,7,9. Each
button makes move in this 
direction:
  1 - forward left;
  3 - forward right;
  7 - backward left;
  9 - backward right.

Captures are mandatory so when
capture is available it must
be done. So checkers which can
capture are marked with red 
circle around them. Then 
selectable checkers are only
those which cam capture.
