Queens #24 was the 7×7 medium board of Monday, October 19, 2026. Our deduction solver, the same one behind the hint button, finishes it in 25 steps without guessing: 18 follow straight from the rules (a queen's neighbours, a line that already has its queen, a line with one free cell left), 7 come from confinement (a region squeezed into one row or column, or several regions sharing the same rows), and none need a “what if” check. The regions range from 2 to 15 cells; the smallest is sky, and small regions are where the board opens up.

How to start Queens #24: the first 12 deductions

Each step is a deduction a person can make, in the order our solver found them. Rows and columns are counted from the top-left corner.

  1. Cross out 5 cells. Every free cell of the sky region is in row 7, so that region's queen must be there — the rest of row 7 is crossed out.

  2. Cross out row 6, column 6. This cell touches every free cell of row 7 — a queen here would leave row 7 with no queen, so it's crossed out.

  3. Cross out row 6, column 7. This cell touches every free cell of row 7 — a queen here would leave row 7 with no queen, so it's crossed out.

  4. Cross out row 3, column 6. This cell touches every free cell of the lavender region — a queen here would leave the lavender region with no queen, so it's crossed out.

  5. Cross out row 4, column 5. This cell touches every free cell of the mint region — a queen here would leave the mint region with no queen, so it's crossed out.

  6. Cross out row 5, column 2. This cell touches every free cell of the orchid region — a queen here would leave the orchid region with no queen, so it's crossed out.

  7. Cross out 5 cells. The lavender region and the sky region all fit inside columns 6 and 7, so those 2 columns' queens are theirs — every other cell in columns 6 and 7 is crossed out.

  8. Queen at row 3, column 5. The mint region has only one free cell left — that must be its queen.

  9. Cross out 5 cells. Queens can't touch, not even diagonally — the cells around this queen are crossed out.

  10. Cross out 4 cells. Row 3 already has its queen — the rest of it is crossed out.

  11. Cross out 3 cells. Column 5 already has its queen — the rest of it is crossed out.

  12. Queen at row 7, column 6. Column 6 has only one free cell left — that must be its queen.

13 more steps follow the same pattern until the 7 queens are placed.
