You will start with a square area covered with numbers, and after a short while, all of these numbers will turn gray, signaling the official start of the challenge. At this point, a timer will count down, and all of the numbers will start moving randomly across the screen. Your task is to destroy all of the gray numbers by touching them. However, you need to be careful, because if you accidentally touch a regular number, the time will decrease faster. The challenge will end when you destroy all of the gray numbers or when the time runs out.
