XYZ-Wing is very similar to Y-Wing with the exception of an extra candidate **Z**
in the hinge cell. Let us phrase the setup in the same way as for Y-Wing. XYZ-Wing requires a **hinge cell** containing
candidates **X**, **Y** and **Z**. The two non-hinge cells must have candidates **XZ** and **YZ**. Eliminations are fewer for this method
, as the eliminated candidate **Z**, should see all three cells.

Let us clarify the setup with the following example. The **hinge** cell is **B5** with candidates **X=2**,
**Y=8** and **Z=3** (Z is highlighted in all cells).

If **B5** is **2**, then **A4** is **3** and we can eliminate the candidate **3** from **B4**.

If **B5** is **8**, then **B1** is **3** and we can
still eliminate the **3** from **B4**.

Finally, if **B5** is **3**, then **B4** cannot be **3**. So in all cases we can eliminate the
highlighted candidate in cell B4.

This example of an XYZ-Wing has 2 eliminations. The **hinge** cell is **F4** with candidates **X=8**, **Y=9** and **Z=7**.
Following the same logic as in the above example, any value we place in the hinge cell would eliminate the **Z**
candidate from **F5** and **F6**.
