Let's solve both Sudoku puzzles step by step. We'll start with Puzzle 1, then move to Puzzle 2.

🔹 Sudoku Rules Reminder:

- Each row must contain digits 1–9 without repetition.
- Each column must contain digits 1–9 without repetition.
- Each of the nine 3×3 subgrids (also called "boxes") must contain digits 1–9 without repetition.

We will use logical deduction to fill in the blanks.

## ✔ Puzzle 1

```
+-------+-------+-------+
| 9 | 1 | 7 | 3 | 2 | 8 | 6 | 5 | 4 |
| 2 | 9 | 8 | 4 | 6 | 5 | 7 | 3 | 1 |
| 3 | 4 | 5 | 2 | 7 | 9 | 8 | 6 | 2 |
| 9 | 7 | 4 | 1 | 5 | 6 | 2 | 8 | 3 |
| 8 | 6 | 2 | 7 | 3 | 4 | 5 | 9 | 1 |
| 5 | 3 | 1 | 8 | 9 | 2 | 4 | 7 | 6 |
| 3 | 4 | 9 | 6 | 8 | 7 | 1 | 2 | 5 |
| 7 | 2 | 6 | 5 | 1 | 3 | 9 | 4 | 8 |
| 8 | 5 | 3 | 9 | 4 | 1 | 6 | 2 | 7 |
+-------+-------+-------+
```

Wait — there are duplicates in this puzzle! For example:
- In Row 3, we have two 2s (at positions 7 and 9).
- In Column 1, we have two 9s (at Row 1 and Row 4).
- In Box 1 (top-left), we have two 9s.

This suggests a mistake in the puzzle or invalid input.

But let’s double-check carefully.

Wait — looking at the original image:

Puzzle 1 (as shown):

```
9 1 _ 7 3 2 _ _ _
2 9 8 4 6 5 7 3 1
3 4 5 2 7 9 8 6 2
9 7 4 1 5 6 2 8 3
8 6 2 7 3 4 5 9 1
5 3 1 8 9 2 4 7 6
3 4 9 6 8 7 1 2 5
7 2 6 5 1 3 9 4 8
8 5 3 9 4 1 6 2 7
```

Now check for duplicates:

- Row 3: `3 4 5 2 7 9 8 6 2` → Two 2s ✘
- Row 9: `8 5 3 9 4 1 6 2 7` → All unique ✔
- Column 1: 9,2,3,9,8,5,3,7,8 → 9 appears twice, 3 twice, 8 twice ✘

So Puzzle 1 is invalid due to duplicate numbers.

> ⚠️ Conclusion: Puzzle 1 has errors and cannot be solved as-is.

## ✔ Puzzle 2

Let’s now examine Puzzle 2:

```
_ 2 5 9 4 3 _ _ _
_ 8 _ 6 7 _ 5 _ 3
1 5 _ 8 2 _ 6 9 4
4 _ 9 5 3 2 _ 6 8
8 6 2 1 9 4 3 5 7
3 2 _ 8 6 5 9 4 1
5 3 1 2 4 6 8 7 9
6 9 4 3 8 7 1 2 5
7 8 3 9 5 1 4 6 2
```

Let’s write it clearly:

```
Row 1: _ 2 5 | 9 4 3 | _ _ _
Row 2: _ 8 _ | 6 7 _ | 5 _ 3
Row 3: 1 5 _ | 8 2 _ | 6 9 4
Row 4: 4 _ 9 | 5 3 2 | _ 6 8
Row 5: 8 6 2 | 1 9 4 | 3 5 7
Row 6: 3 2 _ | 8 6 5 | 9 4 1
Row 7: 5 3 1 | 2 4 6 | 8 7 9
Row 8: 6 9 4 | 3 8 7 | 1 2 5
Row 9: 7 8 3 | 9 5 1 | 4 6 2
```

We’ll solve this step by step using logic.

Step 1: Check if the puzzle is valid (no duplicates)

Check each row, column, and box.

#### Rows:
- Row 1: missing three numbers → okay
- Row 2: missing three → okay
- Row 3: 1,5,?,8,2,?,6,9,4 → two missing
- ...
- All rows seem to have no duplicates so far.

#### Columns:
Let’s scan columns quickly.

- Col 1: _,_,1,4,8,3,5,6,7 → all unique? Yes (missing 2,9)
- Col 2: 2,8,5,_,6,2,3,9,8 → Wait! 2 appears in Row 1 and Row 6 → duplicate? No: Row 1 Col 2 = 2, Row 6 Col 2 = 2 → same column → duplicate!

Wait:
- Row 1, Col 2: 2
- Row 6, Col 2: 2 → both in same column (Col 2) → invalid

So Puzzle 2 also has a duplicate!

Let’s confirm:

Column 2 values:
- R1: 2
- R2: 8
- R3: 5
- R4: ?
- R5: 6
- R6: 2 ← same as R1
- R7: 3
- R8: 9
- R9: 8

So 2 appears twice in Column 2 → invalid

Also, 8 appears twice in Column 2 (R2 and R9) → another duplicate!

So Column 2 has duplicates → Puzzle 2 is invalid.

---

🛑 Final Conclusion:

Both Puzzle 1 and Puzzle 2 contain duplicate numbers, violating Sudoku rules.

Therefore:

> ✘ Neither puzzle is solvable as presented because they contain invalid entries (repeated numbers in rows, columns, or boxes).

Possible Explanation:

The image might have been misprinted or incorrectly copied. Perhaps the blank cells were meant to be filled, but some numbers were duplicated accidentally.

If you can provide a corrected version of either puzzle (or clarify), I’d be happy to solve it.

Alternatively, if these puzzles are from a source that allows such errors, please verify the input.
