Puzzle 1: ADVENT

The letters are: A, D, E, N, T, V.

#### Initial Grid:
```
T D _ _
_ A T N
E _ _ N
A N _ _ T
_ E _ T _
V N _ _ A
```

#### Step-by-Step Solution:
1. Row 1: `T D _ _` → The missing letters are `A, E, N, V`. Since `N` is in Row 2 and Column 4, and `A` is in Row 4, we can place `E` and `V`:
```
T D E V
```

2. Row 2: `_ A T N` → The missing letters are `D, E, V`. Since `D` is in Column 1 and `E` is in Row 1, we can place `V`:
```
V A T N
```

3. Row 3: `E _ _ N` → The missing letters are `A, D, T, V`. Since `A` is in Row 4 and `T` is in Row 2, we can place `D` and `V`:
```
E D V N
```

4. Row 4: `A N _ _ T` → The missing letters are `D, E, V`. Since `D` is in Row 3 and `E` is in Row 1, we can place `V`:
```
A N V E T
```

5. Row 5: `_ E _ T _` → The missing letters are `A, D, N, V`. Since `A` is in Row 4 and `N` is in Row 3, we can place `D` and `V`:
```
D E A T V
```

6. Row 6: `V N _ _ A` → The missing letters are `D, E, T`. Since `D` is in Row 5 and `T` is in Row 4, we can place `E`:
```
V N E D A
```

#### Final Grid for ADVENT:
```
T D E V
V A T N
E D V N
A N V E T
D E A T V
V N E D A

_ F _ Y L
U Y _ _ J
L _ T F _
```

#### Step-by-Step Solution:
1. Row 1: `Y O _ _` → The missing letters are `F, J, L, U`. Since `J` is in Row 2 and `L` is in Row 6, we can place `F` and `U`:
```
Y O F U
```

2. Row 2: `_ J _ _ O Y` → The missing letters are `F, L, U`. Since `L` is in Row 6 and `U` is in Row 1, we can place `F`:
```
L J F U O Y
```

3. Row 3: `_ _ _ U F` → The missing letters are `J, L, O, Y`. Since `J` is in Row 2 and `O` is in Row 2, we can place `L` and `Y`:
```
O L Y U F
```

4. Row 4: `_ F _ Y L` → The missing letters are `J, O, U`. Since `O` is in Row 3 and `U` is in Row 1, we can place `J`:
```
U F J Y L
```

5. Row 5: `U Y _ _ J` → The missing letters are `F, L, O`. Since `L` is in Row 2 and `O` is in Row 3, we can place `F`:
```
U Y F O J
```

6. Row 6: `L _ T F _` → The missing letters are `J, O, Y`. Since `J` is in Row 5 and `O` is in Row 3, we can place `Y`:
```
