Every deduction from the walkthrough above, in order. Each technique is explained in the Star Battle strategy guide.

  1. Starting position — the grid is split into regions (bold outlines). Each row, column, and region needs exactly two stars, and no two stars may touch.
  2. Clump analysis (Region 4): candidate clumps can only just supply the remaining stars (row 7, column 7).
  3. Clump analysis (Region 6): candidate clumps can only just supply the remaining stars (row 2, column 8).
  4. Clump analysis (Region 9): candidate clumps can only just supply the remaining stars (row 4, column 8).
  5. Squeeze (columns 8-9): the band's clumps can only just fit its stars (row 8, column 7).
  6. Undercounting: 5 regions fit in rows 1-5, eliminate 4 outside candidates (row 4, column 1).
  7. Squeeze (columns 1-2): the band's clumps can only just fit its stars (row 2, column 1).
  8. Undercounting: 5 regions fit in cols 5-9, eliminate 3 outside candidates (row 4, column 5).
  9. Squeeze (rows 4-5): the band's clumps can only just fit its stars (row 4, column 4).
  10. Three candidates with two adjacent: Isolated candidate must hold a star (row 5, column 5).
  11. Blocking rule: a star here would touch every other open cell in its region, leaving no room for the region's second star (row 8, column 3).
  12. Blocking rule: a star here would touch every other open cell in its region, leaving no room for the region's second star (row 8, column 4).
  13. Clump analysis (Row 6): candidate clumps can only just supply the remaining stars (row 7, column 1).
  14. Region completion: 1 star needed, 1 candidate (row 4, column 7).
  15. Mark 1 cell adjacent to stars as X (row 3, column 7).
  16. Clump analysis (Row 7): each clump must supply its full share of stars (row 7, column 6).
  17. Mark 3 cells adjacent to stars as X (row 6, column 7).
  18. Region completion: 1 star needed, 1 candidate (row 8, column 8).
  19. Mark 1 cell adjacent to stars as X (row 9, column 8).
  20. Three candidates with two adjacent: Isolated candidate must hold a star (row 6, column 8).
  21. Mark 1 cell adjacent to stars as X (row 5, column 9).
  22. Row completion: 1 star needed, 1 candidate (row 5, column 3).
  23. Mark 2 cells adjacent to stars as X (row 4, column 3).
  24. Row completion: 1 star needed, 1 candidate (row 4, column 9).
  25. Mark 1 cell adjacent to stars as X (row 3, column 9).
  26. Row completion: 1 star needed, 1 candidate (row 6, column 1).
  27. Column 8 complete: Mark 1 remaining cell as X (row 1, column 8).
  28. Blocking rule: a star here would touch every other open cell in its region, leaving no room for the region's second star (row 1, column 6).
  29. Blocking rule: a star here would touch every other open cell in its region, leaving no room for the region's second star (row 2, column 6).
  30. Column completion: 1 star needed, 1 candidate (row 9, column 6).
  31. Mark 1 cell adjacent to stars as X (row 9, column 5).
  32. Column completion: 1 star needed, 1 candidate (row 1, column 5).
  33. Mark 2 cells adjacent to stars as X (row 1, column 4).
  34. Two last candidates (row 8): Eliminate 2 cells adjacent to both (row 9, column 1).
  35. Clump analysis (Row 3): candidate clumps can only just supply the remaining stars (row 2, column 3).
  36. Row completion: 2 stars needed, 2 candidates (row 2, column 7).
  37. Mark 1 cell adjacent to stars as X (row 1, column 7).
  38. Row completion: 1 star needed, 1 candidate (row 2, column 9).
  39. Mark 1 cell adjacent to stars as X (row 1, column 9).
  40. Clump analysis (Row 1): each clump must supply its full share of stars (row 3, column 1).
  41. Mark 1 cell adjacent to stars as X (row 3, column 2).
  42. Column 1 complete: Mark 2 remaining cells as X (row 1, column 1).
  43. Region completion: 1 star needed, 1 candidate (row 8, column 2).
  44. Mark 2 cells adjacent to stars as X (row 7, column 3).
  45. Region completion: 2 stars needed, 2 candidates (row 7, column 4).
  46. Region completion: 1 star needed, 1 candidate (row 9, column 4).
  47. Column completion: 1 star needed, 1 candidate (row 1, column 2).
  48. Mark 1 cell adjacent to stars as X (row 1, column 3).
  49. Column completion: 1 star needed, 1 candidate (row 3, column 3).
  50. Mark 1 cell adjacent to stars as X (row 3, column 4).
  51. Solved! Every row, column, and region has its two stars, none touching.
