LinkedIn Queens #904 answer — October 21, 2026

This Queens has exactly one solution, and you can reach it without guessing. Every step below follows from the rules. A “check” step shows why a queen can't go somewhere; it never asks you to gamble.

1. 1Where to lookShow hint

   The green region is a single cell, so its queen is set from the start. Look at the gray region.
2. 2The first deductionShow hint

   The gray region has one open cell left (row 7, column 7), so its queen goes there.

   Pattern

   Last open cell. When a row, column or region has one open cell left, its queen goes there.
3. 3The first queenShow hint

   Row 1 has one open cell left, in column 1, so its queen goes there.

   Steps 1–5 of the walkthrough rule out the cells marked ×.
4. 4Solve it step by stepShow hint

   Rows count from the top and columns from the left. Every queen rules out the rest of its row, its column and its color region, plus the eight cells around it.

   1. Last open cell. The green region has one open cell left (row 2, column 6), so its queen goes there.
   2. Last open cell. The gray region has one open cell left (row 7, column 7), so its queen goes there.
   3. A region trapped in one column. The blue region lies entirely in column 4, so the queen of column 4 belongs to it and every other cell of column 4 is empty.
   4. A region trapped in one row. The yellow region lies entirely in row 6, so the queen of row 6 belongs to it and every other cell of row 6 is empty.
   5. A column trapped in one region. The open cells of column 5 all belong to the orange region, so its queen sits in column 5 and its other cells are empty.
   6. Last open cell. Row 1 has one open cell left, in column 1, so its queen goes there.
   7. Last open cell. Row 3 has one open cell left, in column 4, so its queen goes there.
   8. Last open cell. The orange region has one open cell left (row 5, column 5), so its queen goes there.
   9. Last open cell. The red region has one open cell left (row 4, column 2), so its queen goes there.
   10. Last open cell. The yellow region has one open cell left (row 6, column 3), so its queen goes there.
