“The Golden Snitch, or Snitch for short, is the fastest and smallest ball on a Quidditch match. It’s known for being extremely hard to see and almost impossible to catch.
The team that catches the Snitch gains 150 points. Catching the Snitch also ends the match and it’s the only way it can be ended.
The Snitch is the size of a walnut and it’s almost always made of gold. The reason why its color is yellow is because it’s the hardest color for the human eye to notice, thus making it even more challenging to catch.”
