Hint 1

Start with region 6. Its candidates are R4C1, R5C1. 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 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):
2 cellsR4C1, R5C1
Hint 2

Observe: region 6 has 2 remaining candidates: R4C1, R5C1. All lie in column 1.

Rule: region 6 needs one Queen, so it will occupy column 1. column 1 can contain no second Queen outside region 6.

Therefore: mark 7 cells (see details) ×.

Therefore: mark R9C6, R9C7, R9C8, R9C9 ×.

Step 8: Observe: row 9 must contain one Queen, chosen from R9C3, R9C4, R9C5.

Rule: Queens cannot share a row, column or region, or touch diagonally. R8C4 conflicts with R9C3, R9C5 through diagonally adjacent cells; with R9C4 through the same column (column 4).

Therefore: mark R8C4 ×. Every possible Queen in row 9 rules out these cells.

Step 9: Observe: column 1 and column 8 and column 9 have remaining candidates 10 cells (see details), all within region 1 and region 6 and region 7.

Therefore: mark R2C4, R2C5, R2C6, R3C4, R3C6, R4C6, R5C6, R6C6 ×.

Step 11: Observe: row 2 must contain one Queen, chosen from R2C2, R2C3.

Rule: Queens cannot share a row, column or region, or touch diagonally. R3C2 conflicts with R2C2 through the same column (column 2); with R2C3 through diagonally adjacent cells. R3C3 conflicts with R2C2 through diagonally adjacent cells; with R2C3 through the same column (column 3).

Therefore: mark R3C2, R3C3 ×. Every possible Queen in row 2 rules out these cells.

Step 12: Observe: row 3 has only one remaining candidate: R3C5.

Rule: every row needs exactly one Queen.

Therefore: place a Queen at R3C5. The 9 cells marked × conflict with it by row, column, region or diagonal adjacency.

Step-by-step walkthrough

The key insight

The opening deduction: Observe: region 6 has 2 remaining candidates: R4C1, R5C1. All lie in column 1.

Rule: region 6 needs one Queen, so it will occupy column 1. column 1 can contain no second Queen outside region 6.

Therefore: mark 7 cells (see details) ×.

View 7 coordinate references

Therefore: mark R1C1, R2C1, R3C1, R6C1, R7C1, R8C1, R9C1 ×.

Your solving route

  1. Steps 1–12: narrow the candidates until R3C5 is forced.
  2. Steps 13–20: use the confirmed Queens to eliminate conflicts, then repeat the deductions for the remaining regions.

A tempting mistake

A Queen at R1C1 looks possible before deductions. Following the forced placements leaves region 6 without a possible Queen. Rule out this tempting assumption.

Check every branch

Region 6 has no possible Queen: contradiction.
