The rules of the game are very simple. Through a small hole you will catch small balls. With each caught, you will increase the power of your core and receive bonus points. Balls fly out very quickly and fly from all directions. And, because you have to act very quickly to catch the maximum number of them. You have the right to make a mistake. But, if too many balls fly by, then the game will end. Try to set the maximum record and have fun collecting balls. Good luck!
