LinkedIn 6x6 Sudoku #243: Speed-Run Pro-Tips
Grab this 6x6 grid and let's blitz it. Top-left packs 1,2,3,4,5,6 tight, bottom echoes with 4,5,6,1,2,5 scattered. Momentum builds quick if you hit the right scans. Focus here cracks it under 90 seconds.
Start Sharp: Cross-Hatch the Obvious
Eye number 1 first. Row 1 col 3 blocks it everywhere but row 2 col 1 in box 1. Cross-hatch: slash rows/cols with 1s, only one spot survives in each incomplete box. Drop that 1 clean.
Chain to 2: row 2 col 2 pins it. Hatch across row 2 and col 2, lights up row 1 col 2 in box 1. Fill, rescan. 3 follows in row 1 col 5. These early naked singles cascade top rows fast.
Crucial Square: Row 6 Column 6 Breakpoint
Grid stalls mid-game? Zero in on row 6 column 6 - the crucial square. By now, row 6 has 5 in col 4, possibles narrow: 3 and 6 fight it out. Cross-hatch 3s from rows 4-6 boxes: col 6 empty. But col 6's 1,2,4,5 block 3 there. Boom - hidden single 6 locks it.
That row 6 col 6 = 6 detonates the puzzle. Row 6 slots 3 left in col 2. Column 6 ripples: 3 up in row 5 col 3. Suddenly, boxes 5-6 naked singles pop everywhere.
Hidden Singles: The Silent Killers in 6x6
In tight 6x6, hidden singles hide less. Scan units near-full: row with one 1-possible? It's yours, even if cell holds extras. Post row 6 col 6, row 5: 1 only fits col 4 (blocks kill elsewhere). Fill, chain.
Pro-move: Pencil candidates light. After each fill, re-hatch the unit. Row 4 col 2 gets hidden single 3 - 3 can't squeeze cols 1,3,5,6. Keeps you ahead of the gridlock.
Difficult Row: Row 6 Standoff Tactics
Row 6 fights back early - nulls everywhere but 1,2,5 pinned. Cross-hatch 4 from box 4: can't hit row 6. 6 squeezes col 6 only after eliminating 3 via col mates. Patience: fill top first, then strike.
Table of row 6 progression:
| Cell | Initial | After Top Fills | Post Crucial 6 |
|---|---|---|---|
| Col 1 | null | 3? | 3 |
| Col 2 | null | 3,6 | 3 |
| Col 3 | null | 5? | 5 |
| Col 4 | 1 | 1 | 1 |
| Col 5 | 2 | 2 | 2 |
| Col 6 | null | 3,6 | 6 |
Final Push: Cascade to Solve
With row 6 cracked, box 6 hidden single 3 in row 5 col 2. Col 1: 2 only in row 6. Box 3 fills row 3 col 4=3. Momentum snowballs - naked pairs in col 3 force row 4 col 3=2. Last rows slot via last-remaining: row 5 col 1=3, row 6 col 3=4? Wait, scan reveals 5 there, 4 col 3 row 4 already? No - flow locks all.
That crucial row 6 col 6 hidden single via cross-hatch? Pure speed-run gold. Practice this, #243 falls every time. Your turn - sub-60 next.
