| 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. |

| 33 | |
| 34 | p The ball may never reach or cross the goal horizontally. |

| 41 | If at the end of an initial or intermediate move one of your pieces is |
