Star Battle #33 was the 10×10 medium board of Friday, November 6, 2026: two stars in every row, column and region, 20 stars in all. Our deduction solver, the same one behind the hint button, places them in 55 steps without guessing. 33 steps follow straight from the rules (a star's neighbours, a line that already has both stars, the last free cells of a line), 15 work out where a line's remaining two stars can sit without touching, 7 come from confinement (a region squeezed into one or two lines), and none need a “what if” check. Regions range from 5 to 18 cells; the smallest are gold and mint.

How to start Star Battle #33: 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 row 3, column 6. The gold region still needs two stars that don't touch — this cell can't be one of them, so it's crossed out.

  2. Cross out row 6, column 4. The sky region still needs two stars that don't touch — this cell can't be one of them, so it's crossed out.

  3. Cross out row 2, column 6. The gold region still needs two stars, and every way to place them without touching puts one next to this cell — so it's crossed out.

  4. Cross out row 2, column 8. The gold region still needs two stars, and every way to place them without touching puts one next to this cell — so it's crossed out.

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

  6. Cross out row 2, column 5. Row 1 still needs two stars, and every way to place them without touching puts one next to this cell — so it's crossed out.

  7. Cross out row 2, column 7. Row 1 still needs two stars, and every way to place them without touching puts one next to this cell — so it's crossed out.

  8. Stars at row 3, column 5 and row 3, column 7. The gold region still needs two stars, and its free cells allow only one way to place them without touching — so they go in.

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

  10. Cross out 3 cells. Stars can't touch, not even diagonally — the cells around this star are crossed out.

  11. Cross out 5 cells. Row 3 already has both its stars — the rest of it is crossed out.

  12. Cross out row 5, column 2. Row 4 still needs two stars, and every way to place them without touching puts one next to this cell — so it's crossed out.

43 more steps follow until all 20 stars are placed.

Star Battle #33 solution

Stars by row: row 1: columns 4 and 6; row 2: columns 1 and 9; row 3: columns 5 and 7; row 4: columns 2 and 9; row 5: columns 4 and 6; row 6: columns 2 and 8; row 7: columns 5 and 10; row 8: columns 3 and 7; row 9: columns 1 and 10; row 10: columns 3 and 8.
