Easy Star Battle answer — October 4, 2026

Full written solution

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: This position would block too many candidates (row 8, column 5).
3. Three candidates with two adjacent: Isolated candidate must hold a star (row 7, column 5).
4. Mark 7 cells adjacent to stars as X (row 6, column 4).
5. Region completion: 2 stars needed, 2 candidates (row 5, column 4).
6. Mark 6 cells adjacent to stars as X (row 4, column 3).
7. Region completion: 1 star needed, 1 candidate (row 9, column 4).
8. Mark 3 cells adjacent to stars as X (row 8, column 3).
9. Region completion: 1 star needed, 1 candidate (row 9, column 6).
10. Mark 2 cells adjacent to stars as X (row 8, column 7).
11. Row 9 complete: Mark 4 remaining cells as X (row 9, column 1).
12. Column 4 complete: Mark 3 remaining cells as X (row 1, column 4).
13. Three candidates with two adjacent: Isolated candidate must hold a star (row 5, column 2).
14. Mark 5 cells adjacent to stars as X (row 4, column 1).
15. Row 5 complete: Mark 4 remaining cells as X (row 5, column 6).
16. Three candidates in a row: Middle cell can't hold a star (row 6, column 8).
17. Row completion: 2 stars needed, 2 candidates (row 6, column 7).
18. Mark 2 cells adjacent to stars as X (row 7, column 7).
19. Row completion: 1 star needed, 1 candidate (row 6, column 9).
20. Mark 1 cell adjacent to stars as X (row 7, column 9).
21. Two-option rule: Cell adjacent to both candidates (row 8, column 2).
22. Three candidates with two adjacent: Isolated candidate must hold a star (row 3, column 1).
23. Mark 3 cells adjacent to stars as X (row 2, column 1).
24. Three candidates with two adjacent: Isolated candidate must hold a star (row 3, column 3).
25. Mark 1 cell adjacent to stars as X (row 2, column 3).
26. Row 3 complete: Mark 5 remaining cells as X (row 3, column 5).
27. Region completion: 1 star needed, 1 candidate (row 2, column 5).
28. Mark 3 cells adjacent to stars as X (row 1, column 5).
29. Column completion: 1 star needed, 1 candidate (row 4, column 6).
30. Mark 1 cell adjacent to stars as X (row 4, column 7).
31. Region completion: 1 star needed, 1 candidate (row 4, column 8).
32. Mark 1 cell adjacent to stars as X (row 4, column 9).
33. Two-option rule: Cell adjacent to both candidates (row 7, column 2).
34. Region completion: 1 star needed, 1 candidate (row 7, column 3).
35. Row 7 complete: Mark 1 remaining cells as X (row 7, column 1).
36. Region completion: 1 star needed, 1 candidate (row 8, column 1).
37. Column 1 complete: Mark 1 remaining cells as X (row 1, column 1).
38. Column completion: 1 star needed, 1 candidate (row 1, column 2).
39. Mark 1 cell adjacent to stars as X (row 1, column 3).
40. Region completion: 1 star needed, 1 candidate (row 2, column 7).
41. Mark 3 cells adjacent to stars as X (row 1, column 7).
42. Row completion: 1 star needed, 1 candidate (row 1, column 9).
43. Mark 1 cell adjacent to stars as X (row 2, column 9).
44. Column completion: 1 star needed, 1 candidate (row 8, column 8).
45. Mark 1 cell adjacent to stars as X (row 8, column 9).
46. Solved! Every row, column, and region has its two stars, none touching.
