Interpreting Chinese text

I’m looking at the user's statement in Chinese which talks about blind football, saying "the ball has secrets, the goal has a code! Blind football matches are fired up." It sounds like they're either sharing something interesting or prompting a discussion. Maybe they want to know more about how blind football works, including the rules and how the ball and goal are marked. I think asking a clarifying question while providing some helpful context would be a good approach!Summarizing blind football

I can provide a concise summary of how 5-a-side blind football works. The ball has internal rattles for sound, and players shout "voy" when approaching. There are boards along the sides, a sighted goalkeeper, and guides behind the goal who direct players. The phrases "球里有玄机" and "球门有暗号" refer to the sound cues from the ball and the guides. Following IBSA rules, matches consist of two 20-minute halves with specific equipment like eye shades for equal conditions.
