Hint 1

Start with region 4. Its candidates are R2C6. Which placement is forced? Remember that each row, column and region needs exactly one Queen.

Starting board: no deductions applied yet.

Hint 1: starting candidates · Small cell numbers identify regions. Rows run from top to bottom; columns from left to right. Dots are candidates, × marks excluded cells. Reasoning basis (round marker):
1 cellsR2C6
Hint 2

Observe: region 4 has only one remaining candidate: R2C6.

Rule: every region needs exactly one Queen.

Therefore: place a Queen at R2C6. The 16 cells marked × conflict with it by row, column, region or diagonal adjacency.

How to solve LinkedIn Queens #904

Step-by-step walkthrough

The key insight

The opening deduction: Observe: region 4 has only one remaining candidate: R2C6.

Rule: every region needs exactly one Queen.

Therefore: place a Queen at R2C6. The 16 cells marked × conflict with it by row, column, region or diagonal adjacency.

Your solving route

  1. Steps 1–1: narrow the candidates until R2C6 is forced.
  2. Steps 2–10: 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 · Only candidate

Observe: region 4 has only one remaining candidate: R2C6.

Rule: every region needs exactly one Queen.

Therefore: place a Queen at R2C6. The 16 cells marked × conflict with it by row, column, region or diagonal adjacency.

Board after step 1 · Small cell numbers identify regions. Rows run from top to bottom; columns from left to right. Dots are candidates, × marks excluded cells. Reasoning basis (round marker):

Step 2 · Only candidate

Observe: region 5 has only one remaining candidate: R7C7.

Rule: every region needs exactly one Queen.

Therefore: place a Queen at R7C7. The 8 cells marked × conflict with it by row, column, region or diagonal adjacency.

Step 3 · Locked candidates

Observe: region 3 has 2 remaining candidates: R3C4, R4C4. All lie in column 4.

Rule: region 3 needs one Queen, so it will occupy column 4. column 4 can contain no second Queen outside region 3.

Therefore: mark R1C4, R5C4, R6C4 ×.

Step 4 · Locked candidates

Observe: region 7 has 3 remaining candidates: R6C1, R6C2, R6C3. All lie in row 6.

Rule: region 7 needs one Queen, so it will occupy row 6. row 6 can contain no second Queen outside region 7.

Therefore: mark R6C5 ×.

Step 5 · Locked candidates

Observe: column 5 has 2 remaining candidates: R4C5, R5C5. All lie in region 2.

Rule: column 5 needs one Queen, so it will occupy region 2. region 2 can contain no second Queen outside column 5.

Therefore: mark R1C2, R1C3 ×.

Step 6 · Only candidate

Observe: row 1 has only one remaining candidate: R1C1.

Rule: every row needs exactly one Queen.

Therefore: place a Queen at R1C1. The 7 cells marked × conflict with it by row, column, region or diagonal adjacency.

Step 7 · Only candidate

Observe: row 3 has only one remaining candidate: R3C4.

Rule: every row needs exactly one Queen.

Therefore: place a Queen at R3C4. The 2 cells marked × conflict with it by row, column, region or diagonal adjacency.

Observe: row 5 has only one remaining candidate: R5C5.

Rule: every row needs exactly one Queen.

Therefore: place a Queen at R5C5. The 0 cells marked × conflict with it by row, column, region or diagonal adjacency.

A tempting mistake

A Queen at R1C2 looks possible before deductions. Following the forced placements leaves column 5 without a possible Queen. Rule out this tempting assumption.

Check every branch

Column 5 has no possible Queen: contradiction.
