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