胶囊 Capsule

标准数独基础上，每个胶囊里包含了一个奇数和一个偶数。

Classic rules applied, each capsule contains one odd and one even.

◆Half judges half

◆判定胶囊里的奇数/偶数 Judge the odd/even number inside

◆全区域奇偶性Parity in the whole region

在六阶胶囊数独中，每个宫内有三个奇数和三个偶数。例题中，两个胶囊和已知数会使用其中的3个奇数和2个偶数，所以我们可以判定C3的奇偶性。

In Capsule 6x6, each Box contains 3 odd and 3 even. In this example, 2 capsule and the given occupy 3 odd and 2 even, so we can judge the parity of C3.
