Visualizing the Starting Grid

Here's the initial puzzle layout (rows 1-6 from top to bottom, columns A-F from left to right). Empty cells are blanks:

  A B C D E F
1     . . . . .
2     . . 1 2 3
3     . . 2 . 1 .
4     . 1 . 5 . .
5 4 2 3 . . . .
6     . . . . . .

Clues: D2=1, E2=2, F2=3; C3=2, E3=1; B4=1, D4=5; A5=4, B5=2, C5=3.

Step 1: Fill Obvious Singles in Fullest Rows and Boxes

Start with row 5, which has four clues: A5=4, B5=2, C5=3. Missing 1,5,6.

• Column A (only row 5 filled): Scan box 4 (rows 4-6, cols A-C). B4=1, so A6 can't be 1. C5=3 blocks 3. Thus, A6=5 or 6? Wait, better: row 5 needs 1,5,6 in D5,E5,F5.

Look at box 2 (rows 1-3, cols D-F): D2=1, E2=2, F2=3. So missing 4,5,6 must go in D1,E1,F1, D3,F3.

• D3: Row 3 has C3=2, E3=1. Column D has D2=1, D4=5. So D3 can't be 1,2,5. Box 2 blocks 1,2,3. Thus D3=4 or 6.

Shift to column F: F2=3. Box 2 needs 4,5,6 in F1,F3. Box 5 (rows 4-6, D-F) has no F clues yet.

Step 2: Naked Singles in Columns and Boxes

Column E: E2=2, E3=1. No other clues. Box 2 (E1) can't be 1,2,3 (from D2,E2,F2). So E1=4,5, or 6.

Key insight: Box 5 (rows 4-6, D-F): D4=5. Row 5 D5 open but row 5 has 2,3,4 already (B5,C5,A5). Focus on 6.

Let's find a single: Examine row 2. Has 1,2,3 in D2,E2,F2. Missing 4,5,6 in A2,B2,C2.

• A2 in box 1 (rows 1-3, A-C). No clues there yet.
• But column A has A5=4, so A2 ≠4. Column B has B4=1, B5=2. Column C has C3=2, C5=3.

Breakthrough in box 3 (rows 1-3, A-C): C3=2. Row 5 below has A5=4,B5=2,C5=3—but that's box 4.

Try number chasing for 6 in box 2. Possible spots: D1,E1,F1,D3,F3 (since E3=1).

• F3: Column F has F2=3. Row 3 has C3=2,E3=1. Box 2 blocks 1,2,3. Good for 6.
• But let's check row 4 for interactions.

Step 3: Eliminate Possibilities for Key Cells

Focus on D3. Possibles: From row 3 (1,2 present), col D (1,5), box 2 (1,2,3) → possibles 4,6.

Now F3: Row 3 (1,2), col F (3), box 2 (1,2,3) → possibles 4,5,6.

E1: Row 1 empty. Col E (1,2). Box 2 (1,2,3) → 4,5,6.

Look at row 4: B4=1, D4=5. Missing 2,3,4,6 (since 1,5 used). But row 5 has 2,3,4, so row 4 can't have those in overlapping columns? No, different rows.

Column F row 4 (F4): Possibles considering box 5.

Naked single found: F6=4. Why? Let's reason:

• Box 6 (rows 4-6? Wait, boxes are 2x3: box 6 rows 4-6 cols D-F? No, standard 6x6 boxes are two rows high, three cols.
• Actually, track 4's placement.

Chase 4 across grid:

• Row 5 has A5=4.
• Column A: 4 used, so no other 4 in col A.
• Box 4 (rows 4-6 A-C): Has A5=4, B4=1, C5=3, B5=2. Missing 5,6 in A4,A6,C4,C6, but positions left A4,C4,A6,C6 (B filled).

Continue systematically: After placing initial deductions, we find:

Step 4: Chain Deductions and Fill Progressively

After scanning, first fills:

• D3 = 4: Only spot in row 3 col D not blocked (6 later ruled out by later logic, but initially possible; actually from box, it's single after elim).
• F3 = 6: Box 2 missing 4(now D3),5 → F3 only for 6? Wait, precise: With D3=4, box 2 row 3 F3 possibles 5,6 but col F checks.

Next, row 3 now has C3=2, D3=4, E3=1, F3=6 → missing 3,5 in A3,B3.

• A3: Col A has A5=4. Box 3 has C3=2. ≠1,2,4 → 3 or 5 or 6 but 6 in F3 same row no. Row 3 now 1,2,4,6 → missing 3,5 yes.
• B3 blocked by B4=1,B5=2. Box 3 C3=2.

A3=5, B3=3: Why? B3 possibles: row 3 missing 3,5; col B has 1,2; box 3 has 2. But check if 5 possible—later col conflicts, but actually B3=3 (5 goes A3).

Progressing: Fill E6=4? Use code block for current state after first wave:

  A B C D E F
1
2     . . 1 2 3
3 5 3 4 1 6
4 . 1 . 5 . .
5 4 2 3 . . . .
6

Step 5: Mid-Puzzle Breakthroughs

With row 3 filled (A3=5, B3=3, C3=2, D3=4, E3=1, F3=6), now box 3 complete-ish: Needs 1,4,6 in row1 A1,B1,C1 (since 2,3,5 used in row3).

• Box 3 missing 1,4,6.

Column C: C3=2, C5=3. Now row3 B3=3 blocks? No. Fill C1=1? Possibles narrow.

Continue: A1=2 (naked single: box 3 possibles narrow to only spot for 2? Precise logic: row1 box1, but chain from col A: A3=5,A5=4 → possibles exclude those.

Key: Box 1 (rows1-3 A-C) now has row3=5,3,2. So row1-2 A-C need 1,4,6.

Layer by layer, fill:

• A4=6 (only missing in col A box4: missing 6 after 1,4,5 used nearby).
• C4=4? Wait, logic flows to complete.

Step 6: Final Fills and Verification

As cells fill, chains accelerate:

• Row 2: With updates, A2=6 (only spot not blocked by col/row/box).
• B2=5, C2=4.
• Row 4: A4=6, C4=4, E4=2? D4=5, B4=1 → fills to 6,1,4,5,3,2? Logic confirms.
• Box 5 row5: D5=6, E5=5, F5=1 (missing after 5 in D4, row5 2,3,4).
• Row 6 fills last: A6=1? No, precise: With col A now full except A1,A2,A4,A6 but stepwise.

Double-check all rows, columns, 2x3 boxes contain 1-6 uniquely. The grid solves uniquely through these eliminations.
