You already created:

but don't use it in `CalculateScore()`.

Replace magic numbers:

Case ScoreCategory.FullHouse
```

instead of:

```vb
Case 8
```

---

### 42. Create a Score Engine Class

Move scoring logic into:

```vb
Public Class ScoreCalculator
```

This makes future rule additions much easier.

---

### 43. Use a Dice Class

```vb
Public Class Die
    Public Value As Integer
    Public Held As Boolean
End Class
```

Cleaner than parallel arrays.

---

### 44. Add Unit Tests

Test scoring functions independently.

```vb
TestFullHouse()
TestYahtzee()
TestLargeStraight()
```

---

### 45. Add Configuration Settings

Allow customization:

* Number of rolls
* Yahtzee bonus amount
* Theme
* Sound on/off

3. Game over detection
4. New Game button
5. Save/Load game
