If you think this game is ok, count it. If it is less than 100, everyone can't stop. It must be smooth. If it is slow or wrong, it is a loss. Whoever loses, we'll give him more trouble.

The specific gameplay is: you must shout "Guo" every seven days, that is to say, whether it is a number containing 7 or a number divisible by 7, you must shout "Guo" every other day.

Do you think it's okay? If not, I will think of one for you. The answer is not easy. I hope it can be adopted. Thank you~
