"Let the ball bounce around the space.
Every time it hits a number, it subtracts 1 until it disappears. You need to find the right angle to keep the ball bouncing. This way, you can maintain the best performance within a certain timeframe.
You can also let the ball touch skills to eliminate a row of numbers.

You can also increase the number of balls by touching them. The more balls you have, the better the elimination effect."
