LinkedIn 6x6 Sudoku #223: Speed-Run Pro-Tips

Jump into #223 like a pro. This 6x6 beast starts symmetric but hides thorns in rows 2 and 4. Scan fast: row 2 gives 1,2,3; row 4 packs 5,3,1,6. Your first move? Cross-hatch column 6 for quick wins.

Opening Salvo: Cross-Hatching Column 6

Eye column 6. Row 2 blocks 3 (from row 2 col 5), row 4 blocks 6. Row 1 and 5 are wide open in that stack. Cross-hatch row 1: no 4/5/6 yet, but row 2's 1/2/3 force 4/5/6 into row 1's empty trio. Boom, row 1 col 6 must be 1 (only spot left after row 4's 6 blocks elsewhere). Fill it. Chain reaction: row 1 now demands 4/3/5/2/6 across empties.

Hidden Singles Strike: Row 3 Momentum

With row 1's 1 locked, hunt hidden singles. Row 3 col 6: scan box and column. 1 taken in row 1, 6 in row 4, 5/3 blocked nearby. Only 2 fits. Slam it in. Row 3 col 1 opens next: column 1 sees row 4's 5, so 6 squeezes in via box limits. You're rolling.

Crucial Square: Row 5 Col 2, The Grid-Breaker

Here’s the crucial square: row 5 col 2. This difficult row (row 5) stalls until now. Cross-hatch it against box 2 and column 2. Upstream fills block 1/3/6 in col 2 (row 1 has 3, row 4 empty but box-forced). 4 lurks elsewhere, leaving hidden single 5 for row 5 col 2. Why crucial? It ignites row 5: 2/4/6/5 cascade left-to-right, box 5 fills, and column 2 cracks row 6 wide open with 3/1 left. Puzzle unravels in 20 seconds from here.

Advanced Chains: Pointing Pairs in Boxes

Post-crack, row 4 col 5: pointing pair from box 4 (4/2 duel). Eliminates peers in row 4, forcing 4 there. Hidden triple in row 6 box 3 (3/1/5) wipes alternatives. No naked pairs yet; this is pure 6x6 squeeze. Re-scan columns after each fill, or you miss the cascade.

Final Sprint: How It All Clicks

Row 5 col 2 drops the domino. Row 5: 2-4-6-5-1-3. Row 6 col 1 grabs 3 (column 1 only spot). Box 6 forces 5-1-6-2-4. Columns align, boxes seal. Total speed-run: under 90 seconds by chaining singles to pairs. Practice this flow on #223; next one's yours.
