2 | Pieces don't capture but can kick a ball.
3 | The object of the game is to send the ball into the enemy goal.
6 At each turn, a player can first make a normal (non capturing) move.
7 If none of his pieces are adjacent to the ball, such move is mandatory.
8 But, if any of his pieces stand next to the ball he may then or right
9 away kick it, if the line piece <--> ball is compatible
10 with the piece's movement.
13 To play a kick, click on the ball and then on the desired square.
14 The knight send the ball at any knight-step away from its initial position,
15 except on squares adjacent to the knight.
16 However, when the ball is in a corner an exception to this rule is allowed:
17 on the following diagram "kick from g1 to h3" is allowed".

29 To avoid infinite cycles, each piece can kick the ball at most
32 p Pieces cannot stand in any goal square.
34 p The ball may never reach or cross the goal horizontally.
36 p No score at first move (possible in some 960 configurations).
38 h4 Complete a move on the interface.
41 If at the end of an initial or intermediate move one of your pieces is
42 adjacent to the ball, you'll need to "capture" any of your pieces
43 with the ball to indicate that the move is over.
46 Note: bishops stuck in the corner have the extra option
47 to jump over the obstacle. Useful in some randomized setups.
