钻石 Diamond

标准数独基础上，钻石中间的格是四角之和的因数。

Classic rules applied. Additionally, the center of the diamond, is the factor of the sum of four diamond sides.

◆中心是四角之和的因数，也是四角之和加自身的因数，因此是整个钻石之和的因数。

The center is the factor of 4-sides, and 4-sides add itself. We can say it's the factor of the diamond.

◆特殊的1 Special 1

你能解答问号格吗？你可能需要试数。如果没有任何办法能从一个钻石的中心移除1，它一定是数字1。

Can you solve the ？cell? You may need to try. However, if no way can delete 1 from a center of a diamond, it must be 1.
