Netiporo is a fast game and for some people, it can be hard, but, for someone who has played for 6-7 I think I know a bit, but it does not mean I'm perfect. Netball has some rules so though so let me tell you some of the main rules of Netball.
1st) each team must have 7 players.
2nd) if a player touches or hits the other player with the ball, that's considered as contact.
3rd) if a player is not further than three feet away from the other player with the ball, the umpire will blow the whistle for obstruction.
4th) when the player has the ball and removes their foot from the ground that is called an infringement and it is also called stepping.
These are easy rules, they help you to understand the game while/when you are playing. There are also other rules that you will learn when playing so keep it up!
