Hint 1

Start with region 6. Its candidates are R4C8, R5C8. Can you spot a shared row, column or region? Remember that each row, column and region needs exactly one Queen.

Starting board: no deductions applied yet.

Hint 2

Observe: region 6 has 2 remaining candidates: R4C8, R5C8. All lie in column 8.

Rule: region 6 needs one Queen, so it will occupy column 8. column 8 can contain no second Queen outside region 6.

Therefore: mark R1C8, R2C8, R3C8, R6C8, R7C8, R8C8 ×.

How to solve LinkedIn Queens #899

Step-by-step walkthrough

The key insight

The opening deduction: Observe: region 6 has 2 remaining candidates: R4C8, R5C8. All lie in column 8.

Rule: region 6 needs one Queen, so it will occupy column 8. column 8 can contain no second Queen outside region 6.

Therefore: mark R1C8, R2C8, R3C8, R6C8, R7C8, R8C8 ×.

Your solving route

  1. Steps 1–2: narrow the candidates until R1C7 is forced.
  2. Steps 3–18: use the confirmed Queens to eliminate conflicts, then repeat the deductions for the remaining regions.

Open each deduction to see the observation, rule and board changes.

Step 1 · Locked candidates

Observe: region 6 has 2 remaining candidates: R4C8, R5C8. All lie in column 8.

Rule: region 6 needs one Queen, so it will occupy column 8. column 8 can contain no second Queen outside region 6.

Therefore: mark R1C8, R2C8, R3C8, R6C8, R7C8, R8C8 ×.

Step 2 · Only candidate

Observe: region 2 has only one remaining candidate: R1C7.

Rule: every region needs exactly one Queen.

Therefore: place a Queen at R1C7. The 14 cells marked × conflict with it by row, column, region or diagonal adjacency.

Step 3 · Common exclusions

Observe: region 3 must contain one Queen, chosen from R2C4, R3C3, R3C4, R4C3.

Rule: Queens cannot share a row, column or region, or touch diagonally. R2C3 conflicts with R2C4 through the same row (row 2); with R3C3, R4C3 through the same column (column 3); with R3C4 through diagonally adjacent cells. R4C4 conflicts with R2C4, R3C4 through the same column (column 4); with R3C3 through diagonally adjacent cells; with R4C3 through the same row (row 4).

A tempting mistake

A Queen at R1C1 looks possible before deductions. Following the forced placements leaves column 7 without a possible Queen. Rule out this tempting assumption.

Check every branch

Column 7 has no possible Queen: contradiction.
