Rules for Quidditch with tennis ball and piassava brooms

This is something I found hidden in the depths of my computer. I wrote it many years ago as a joke to my nephew. I hope someone else enjoys it too. I only spent about 30-45 minutes translating it from Swedish so let me know if you find something grammatically incorrect.

Rules for Quidditch with tennis ball and piassava brooms
01. If you join the game, don't cry about it.
02. Anything that isn't explicitly illegal is legal.
03. Breaking of rules results in a 10 point reduction.

08. All players should keep their bodily fluids to themselves. So it is not allowed to spit, pee, or bleed on another player.
09. A player's equipment is a piassava broom, shoes, socks, shorts and a shirt. Underwear is optional.
10. The ball should be a regular tennis ball. Although a colourful tennis ball is of course much more fun than a regular boring green/yellow one.
11. Each player as well as the referee uses one (1) piassava broom as a stick horse with the broom part towards the ground.
12. Each team should have their own coloured brooms. The crazier the colour the better.

14. Each team has seven (7) players. One (1) goaltender, three (3) attackers, two (2) defenders and one (1) small skinny bloke.
15. The goaltender should do his/her best to defend the own goal. If he/she manages to get the ball he/she will then throw it to one of the attackers. Preferably one of the attackers in his/her own team.
16. The defenders should try to take the ball from the attackers in the opposing team and then throw the ball to one of the attackers in his/her own team.
17. The goaltender and the defenders are not allowed to throw the ball to each other.

19. The attackers are not allowed to take the ball back from the opposing team's defenders or goaltender.
20. The small skinny bloke should run around and look for small flying golden balls.
21. The field is made up by two (2) halves. On the own half you have the goaltender and the defenders. They are not allowed to cross midfield into the opposite team's half. On the opposite team's half are the attackers. They are not allowed to cross midfield into the own half. The small skinny bloke can move anywhere he wants.

23. Players can move freely all over the half they are allowed to be on.
24. There is no out-of-bounds so as long as nobody (except the small skinny bloke) crosses the centre line they can go wherever they want.
