Abalone rules:
--------------
Ablone is simple to play. You can push one to three marbles along the board
in six directions:

                          left up       right up
                                  \   /
                             left - Û - right
                                  /   \
                        left down       right down

You can do this by clicking on the marble you want to move and then on the
next field you want to move it to.
If you want to move two or three balls at once, click on the last ball in
this row and "push" the other two in your desired direction.
If you have marked a ball already but want to select another one without
moving, click the right mousebutton inside the playfield to unmark the ball.
The target of the game is to push six opponent's balls off the board.
To push an opponent's ball, you have to have two or three balls (of your
color) in a row. One-on-one does not work. To push two opponent-balls at once
you must have three of your balls in a row. In other words, your row must
be longer than your opponent's row (max. three).

Example:

        Û °             No go, 1:1
        ->

        Û Û °           White pushes black
        ->

        Û Û ° Û         Not possible, black is blocked by white ball
        ->

        Û Û Û °         Yep, it works
        ->

        Û Û Û ° °       Another possible move
        ->

The game checks for (almost all) valid moves, just play around with it and
you will see what I mean.
It is also legal to move a row of two or three of your balls "sideways"
(not in the direction the row is pointing to). In this version, you need
to klick each ball individually and move it in the desired direction.
