LinkedIn 6x6 Sudoku #234: Speed-Run Breakdown

Drop into #234 with eyes on the givens: row 1 packs 1 and 5, row 2 hits 2,1,6. This 6x6 beast starts smooth but jams mid-solve. Veteran move: scan by number, not cell. Hunt 3's first—they're sparse.

Opening Salvo: Constrained Rows & Singles

Row 2 screams hidden single for 5—only spot left after 2,1,6 block others. Slam it in column 2. Row 5 locks 2 via naked single in column 2. Boom, two placements, chain reaction starts. Pro-tip: in 6x6, nearly full rows (4+ givens) yield instant wins. Row 3's 2 forces cross-checks early.

Cross-Hatching Mastery on Columns

Grab cross-hatching: for 4 in column 6, slash out row 2's 6 and row 5's 3. Pins to row 1 or 3. Box 3 blocks row 3, so row 1 column 6 must be 4. Pencil-mark ruthlessly—6x6 grids flip fast with notes. This nets column 4's chain: 4 forces 3 elsewhere.

The Crucial Square: Row 4, Column 6

Stuck? Row 4 column 6 is your breaker. After filling edges, it's the difficult row's linchpin. Cross-hatch 1's: row 4 sees 1 blocked in columns 1,4; box 3 empty slot screams 1. Place it. Watch dominoes: unlocks row 3 column 6 as 4 (only spot left), then row 6 column 6 as 5. Entire right stack collapses.

Hidden Pairs & Box Elimination

Mid-game, box 2 row 3: 5 and 1 pair hides—eliminates from column 2 row 3. Box 5 chases 6: column 6's 5 forces it top-left. Alternate scans: rows to columns to boxes. Re-check after each fill—6x6 propagation is lightning.

Final Sprint: The Crack Open

With row 4 column 6 nailed, row 3 fills via elimination (5 top, 1 next, 6 follows). Row 6 slots 6 via box 6 singles. Left side mirrors: column 1 hidden singles drop 3,4,5 in order. Last boxes clean via process of elimination—no guesswork. Total speed-run: 1:15 if you hit the crucial square clean.

Pro-Tips for #234 Domination

• Number scan priority: 3,4,5—givens cluster 1,2,6.
• Pencil turbo: Mark possibles in 2-cell rows first.
• Box-row dance: When row stalls, flip to box constraints.
• No backtrack: Logical only—re-scan kills jams.
