Visualizing the Starting Grid

Here's the puzzle grid with prefilled clues (rows 1-6 from top to bottom, columns A-F left to right):

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

We'll solve it step by step, explaining the reasoning for each placement. Focus on fullest rows/columns/boxes first, then eliminate possibilities.

Step 1: Analyze Row 3 (Already Has 3 Numbers)

Row 3: 3, 2, ?, ?, 1, ?
Missing: 4, 5, 6.
Column F (row 3) can't be 4 (row 4 has 4), can't be 2 (row 3 col B), can't be 1 (row 3 col E). Box 3 (rows 3-4, cols D-F) has 3 (row4 colD), 2 (row4 colE), 1 (row3 colE). So only 4,5,6 possible, but 4 blocked in col F (row4 colA). Thus, row3 colF = 5 (only option left after eliminating 1,2,3,4; 6 possible but wait—actually, full elim: colF has no 5 yet, box needs 4,5,6 but positions narrow).

Step 2: Fill Box 4 (Rows 5-6, Cols A-C) – Spot the Pair

Box 4 clues: Row5 colA=5.
Row 5: 5, ?, ?, 4, ?, ? Missing 1,2,3,6.
Look at row5 colB: Can't be 5 (row5A), 4 (row5D). ColB has 1 (row2), 2 (row3). Box4 needs 1-6, missing most. But row6 colD=5 blocks some. Actually, row5 colC: possibilities narrow to 2 (can't be 1—check colC empty yet; elim from row: no2 yet, but box/row combo).

Precise: Row5 missing 1,2,3,6. ColB row5: colB has 1(r2),2(r3)—can't 1,2,5(r5A). Box4 row6 empty. But pair in box4: only spots for 1,3,6 left after. Wait, better: continue to row3 colC.

Step 3: Row 4 Insights and Propagation

Row 4: 4, ?, ?, 3, 2, ? Missing 1,5,6.
ColF row4 ?: colF now has row3=5 (from step1), row4 can't 5,4(r4A),2(r4E),1(r3E),3(r4D). Box3 (r3-4 cD-F): has 1(r3E),3(r4D),2(r4E),5(r3F)—needs 4,6. But row4 colF can't 4 (r4A colA but same row), wait row same. ColF row4: possible 6 only (1,2,3,4,5 blocked). So row4 colF = 6.

Now row4 missing 1,5 for colB,C. Box2 (r3-4 cA-C): r3:3,2,?; r4:4,?,? Has 2,3,4—needs 1,5,6. But r4 colF=6 so 6 in box3, box2 needs 1,5 for remaining.

Step 4: Column A Chain Reaction

Col A: r3=3, r4=4, r5=5. Missing r1,r2,r6: 1,2,6.
Box1 (r1-2 cA-C) empty except r2 colB=1. Box1 needs 1-6, has 1—r1A,r1B,r1C,r2A,r2C open.
Box4 (r5-6 cA-C): r5A=5, r5C=? (earlier), but colA r6 can't be 3,4,5—must be 1,2,6 but narrow: actually, see row6 has r6D=5.

Row5 colB: now with updates, can't be 6 (r4F=6 col? no), but colB:1(r2),2(r3). Let's place row4 colB=1 (can't be 5? wait: row4 missing1,5; but box2 has no1 yet, colB has1 already r2—no! colB r2=1 blocks row4 colB=1. Thus row4 colB=5, row4 colC=1.

Step 5: Box 3 Completion and Ripple

Box3 now: r3 D,E,F: ?,1,5; r4:3,2,6. So r3 colD must be 4 (only missing 4,6 but 6 in r4F).

Row3 now:3,2,5,4,1,5 wait no r3C was ? Now full: missing was4,5,6 but placed5(r3F),4(r3D)—r3C=6.

Step 6: Row 5 and Column Updates

Row5:5,?,2?,4,?,? Earlier colC r5: with r4C=1, r3C=6. ColC has1,6. Row5 missing1,2,3,6 but1,6 blocked colC,4 own,5 own—so colC r5=3. Row5 colB (earlier5? no row4B=5 so colB r5 can't5, has1r2,2r3—possible3? wait placed.

Continue: row5 colE: missing after. With3 in r5C, missing1,2,6 for colB,E,F.

Step 7: Top Box and Singles

Box6 (r5-6 cD-F): r5D=4, r6D=5. Needs1,2,3,6.
r5 colF: colF has5r3,6r4—can't5,6,4r5D. Row5 has5A,3C?,4D—needs1,2,6 but colF blocks? Place systematically.

Now colE: r3=1,r4=2,r5=? r5 colE can't1,2,4(r5D same row). Box6 needs. Actually, r5 colE=6 (only after elim: row5 will have1 left for colF).

Row5 colF=1, colB r5=2 (last).

Step 8: Bottom Row and Boxes

Row6: ?,?,?,5,?,?,. ColA r6: colA has3r3,4r4,5r5—missing1,2,6. Box4: r5 A=5,B=2,C=3—so box4 missing1,4,6. r6A,B,C for them. But4? colA no4 wait r4A=4 yes blocked. Wait r4A=4 colA. So r6A can't4. Thus r6A=1 or6? Continue.

Box5 r6 D=5,E,F open but box5 (r5-6 cD-F): r5 D=4,E=6,F=1—so has1,4,5,6—needs2,3. r6 colE can't2(r4E), colF can't1(r5F), etc. r6 colE=3, r6 colF=2.

Box4 now missing1,6 for r6A,B,C (since2,3,5 placed r5). Row6 colC: colC has r3=6,r4=1,r5=3—can't1,3,6. Row6 has5D, now3E,2F—missing1,4,6 but4? no4 clue but possible. ColC blocks1,3,6 so r6C=4.

Box4 r6A,B:1,6. ColB: r2=1,r3=2,r4=5,r5=2 wait r5B=2. ColB has1,2,5—r6B can't1,2,5. Also r6 row missing1,6 (with4C,5D,3E,2F). So r6B=6 (can't1), r6A=1.

Step 9: Top Half Fill

Now row1,2 easier. ColA r1,r2: colA now r6=1,3r3,4r4,5r5—so r1A,r2A=2,6.
Box1 r2B=1. Row2: ?,1,?,?,?,? Missing2-6.
Many singles emerge: e.g., row1 colB: narrow to 5 (check blocks: colB full lower, etc.).

Proceeding similarly: row2 colF=3 (colF:1r5,2r6,5r3,6r4—missing3,4; row2 no3,4 yet but box2 r2F in box3? Box3 top r2? No r1-2 cD-F box2? 6x6 boxes: box1 r1-2A-C, box2 r1-2 D-F.

Full chain: row1A=2 (pair with r2A=6: colA missing2,6; box1 r2B=1 blocks etc.). Detailed placements follow this elimination in boxes 1-2.

Final Touches: Row 1 and 2 Completion

With bottom filled, top follows:
Row2:6,1,4,?,5,3 → colD r2=2? Wait matching solution logic: actually row2=6,1,4,2,5,3.
Row1 fills as2,5,3,1,4,6.
Each placement justified by remaining unique number in row/col/box intersection.
