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. 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 8).
  3. Clump analysis (Region 2): candidate clumps can only just supply the remaining stars (row 7, column 4).
  4. Clump analysis (Region 4): candidate clumps can only just supply the remaining stars (row 8, column 2).
  5. Clump analysis (Region 5): candidate clumps can only just supply the remaining stars (row 8, column 7).
  6. Clump analysis (Region 7): candidate clumps can only just supply the remaining stars (row 4, column 6).
  7. Clump analysis (Region 2): candidate clumps can only just supply the remaining stars (row 6, column 2).
  8. Clump analysis (Region 9): candidate clumps can only just supply the remaining stars (row 6, column 7).
  9. Undercounting: 2 regions fit in cols 1-2, eliminate 1 outside candidate (row 9, column 2).
  10. Clump analysis (Column 2): candidate clumps can only just supply the remaining stars (row 2, column 1).
  11. Clump analysis (Region 2): candidate clumps can only just supply the remaining stars (row 8, column 4).
  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 6).
  13. Clump analysis (Column 4): candidate clumps can only just supply the remaining stars (row 2, column 5).
  14. Crowding (Region 1): a star here would leave too little room for its 2 remaining stars (row 3, column 5).
  15. Generalized counting (rows 7-9): region star limits exclude these cells (row 7, column 5).
  16. Three candidates with two adjacent: Isolated candidate must hold a star (row 3, column 6).
  17. Mark 4 cells adjacent to stars as X (row 2, column 6).
  18. Two-option rule: Cell adjacent to both candidates (row 5, column 4).
  19. Three candidates with two adjacent: Isolated candidate must hold a star (row 4, column 4).
  20. Mark 2 cells adjacent to stars as X (row 3, column 4).
  21. Region completion: 1 star needed, 1 candidate (row 2, column 4).
  22. Mark 2 cells adjacent to stars as X (row 1, column 4).
  23. Region completion: 1 star needed, 1 candidate (row 6, column 5).
  24. Mark 2 cells adjacent to stars as X (row 5, column 6).
  25. Blocking rule: a star here would touch every other open cell in its region, leaving no room for the region's second star (row 9, column 6).
  26. Column completion: 1 star needed, 1 candidate (row 1, column 6).
  27. Mark 1 cell adjacent to stars as X (row 1, column 7).
  28. Three candidates with two adjacent: Isolated candidate must hold a star (row 9, column 7).
  29. Mark 1 cell adjacent to stars as X (row 9, column 8).
  30. Clump analysis (Region 8): candidate clumps can only just supply the remaining stars (row 3, column 8).
  31. Crowding (Row 5): a star here would leave too little room for its 2 remaining stars (row 4, column 8).
  32. Clump analysis (Column 8): candidate clumps can only just supply the remaining stars (row 1, column 9).
  33. Clump analysis (Column 8): each clump must supply its full share of stars (row 7, column 8).
  34. Mark 3 cells adjacent to stars as X (row 6, column 9).
  35. Region completion: 1 star needed, 1 candidate (row 9, column 9).
  36. Row 9 complete: Mark 3 remaining cells as X (row 9, column 1).
  37. Region completion: 1 star needed, 1 candidate (row 8, column 5).
  38. Column completion: 1 star needed, 1 candidate (row 5, column 7).
  39. Region complete: Mark 1 remaining cell as X (row 1, column 8).
  40. Column completion: 1 star needed, 1 candidate (row 2, column 8).
  41. Mark 1 cell adjacent to stars as X (row 3, column 9).
  42. Row 2 complete: Mark 1 remaining cell as X (row 2, column 2).
  43. Three candidates in a column: Middle cell can't hold a star (row 7, column 3).
  44. Region completion: 2 stars needed, 2 candidates (row 6, column 3).
  45. Mark 1 cell adjacent to stars as X (row 5, column 2).
  46. Region completion: 1 star needed, 1 candidate (row 8, column 3).
  47. Row 6 complete: Mark 1 remaining cell as X (row 6, column 1).
  48. Row completion: 1 star needed, 1 candidate (row 7, column 1).
  49. Mark 1 cell adjacent to stars as X (row 8, column 1).
  50. Region completion: 1 star needed, 1 candidate (row 5, column 1).
  51. Mark 1 cell adjacent to stars as X (row 4, column 2).
  52. Row completion: 1 star needed, 1 candidate (row 4, column 9).
  53. Mark 1 cell adjacent to stars as X (row 5, column 9).
  54. Column 1 complete: Mark 2 remaining cells as X (row 1, column 1).
  55. Region completion: 2 stars needed, 2 candidates (row 1, column 2).
  56. Region completion: 1 star needed, 1 candidate (row 3, column 2).
  57. Solved! Every row, column, and region has its two stars, none touching.
