Hint 1

Start with region 4. Its candidates are R3C5, R3C6. 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.

Step-by-step walkthrough

The key insight

The opening deduction: Observe: region 4 has 2 remaining candidates: R3C5, R3C6. All lie in row 3.

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

Therefore: mark R3C1, R3C2, R3C3, R3C4, R3C7, R3C8 ×.

Your solving route

  1. Steps 1–7: narrow the candidates until R3C5 is forced.
  2. Steps 8–14: use the confirmed Queens to eliminate conflicts, then repeat the deductions for the remaining regions.

A tempting mistake

A Queen at R1C2 looks possible before deductions. All 2 terminal branches run out of candidates in region 8, row 2. Rule out this tempting assumption.

Check every branch

  1. Try R3C5.

    The only candidate in row 2 forces R2C7.

    The only candidate in row 4 forces R4C3.

    The only candidate in region 7 forces R6C4.

    The only candidate in region 5 forces R5C6.

    Region 8 has no possible Queen: contradiction.

  2. Try R3C6.

    Row 2 has no possible Queen: contradiction.

Keep practicing
