Bridges of the week: week 2

The full logical solve of the hard Bridges for September 8 to September 14, 2026, 14 × 14. 36 steps, 6 techniques, no guessing. Step through it, or jump to any step below.

Only one neighbor left. The 2 at row 1, column 2 needs 2 more, and only the 3 at row 1, column 5 can still take bridges. So it gets two bridges to the 3 at row 1, column 5.
Step 1 of 36

Every step

  1. The 2 at row 1, column 2 needs 2 more, and only the 3 at row 1, column 5 can still take bridges. So it gets two bridges to the 3 at row 1, column 5.

  2. The 4 at row 2, column 1 needs 4, and its neighbors can take 4 at most. So it takes all of them: two bridges to the 2 at row 2, column 3 and two bridges to the 4 at row 4, column 1.

  3. The 1 at row 2, column 14 needs 1 more, and only the 3 at row 4, column 14 can still take bridges. So it gets one bridge to the 3 at row 4, column 14.

  4. The 2 at row 5, column 8 needs 2 more, and only the 5 at row 7, column 8 can still take bridges. So it gets two bridges to the 5 at row 7, column 8.

  5. The 1 at row 12, column 8 needs 1 more, and only the 2 at row 10, column 8 can still take bridges. So it gets one bridge to the 2 at row 10, column 8.

  6. The 5 at row 7, column 8 needs 5, and its neighbors can take 5 at most. So it takes all of them: two bridges to the 4 at row 7, column 3 and one bridge to the 2 at row 10, column 8.

  7. The 1 at row 13, column 5 needs 1 more, and only the 2 at row 11, column 5 can still take bridges. So it gets one bridge to the 2 at row 11, column 5.

  8. The 3 at row 14, column 1 needs 3, and its neighbors can take 3 at most. So it takes all of them: one bridge to the 1 at row 11, column 1 and two bridges to the 5 at row 14, column 3.

  9. The 4 at row 4, column 1 needs 4, one less than the 5 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 2 at row 9, column 1.

  10. The 5 at row 4, column 5 needs 5, one less than the 6 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 4 at row 4, column 9 and at least one bridge to the 3 at row 6, column 5.

  11. The 6 at row 4, column 12 needs 6, one less than the 7 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 4 at row 4, column 9, at least one bridge to the 3 at row 4, column 14, and at least one bridge to the 3 at row 6, column 12.

  12. The 4 at row 7, column 3 needs 4, one less than the 5 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 5 at row 9, column 3.

  13. The 5 at row 14, column 3 needs 5, one less than the 6 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 5 at row 9, column 3 and at least one bridge to the 5 at row 14, column 7.

  14. The 5 at row 14, column 7 needs 5, one less than the 6 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 2 at row 9, column 7 and at least one bridge to the 5 at row 14, column 9.

  15. The 5 at row 14, column 9 needs 5, one less than the 6 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 2 at row 11, column 9 and at least one bridge to the 4 at row 14, column 12.

  16. The 2 at row 14, column 14 needs 2, one less than the 3 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 4 at row 14, column 12.

  17. The bridge between the 4 at row 7, column 3 and the 5 at row 7, column 8 blocks the way from the 3 at row 6, column 5 to the 2 at row 9, column 5. The 3 at row 6, column 5 needs 3, and its neighbors can take 3 at most. So it takes all of them: a second bridge to the 5 at row 4, column 5 and one bridge to the 1 at row 6, column 7.

  18. The 3 at row 6, column 12 needs 3, one less than the 4 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 6 at row 9, column 12.

  19. The bridge between the 5 at row 9, column 3 and the 5 at row 14, column 3 blocks the way from the 2 at row 11, column 5 to the 1 at row 11, column 1. The 2 at row 11, column 5 needs 1 more, and only the 2 at row 9, column 5 can still take bridges. So it gets one bridge to the 2 at row 9, column 5.

  20. A bridge between the 3 at row 1, column 5 and the 1 at row 1, column 12 would close off a group of 3 full islands, so it can’t be there. The 3 at row 1, column 5 needs 1 more, and only the 5 at row 4, column 5 can still take bridges. So it gets one bridge to the 5 at row 4, column 5.

  21. The 1 at row 1, column 12 needs 1 more, and only the 6 at row 4, column 12 can still take bridges. So it gets one bridge to the 6 at row 4, column 12.

  22. A double bridge between the 4 at row 4, column 1 and the 2 at row 9, column 1 would close off a group of 4 full islands, so they share one bridge at most. The 4 at row 4, column 1 needs 1 more, and only the 1 at row 4, column 3 can still take bridges. So it gets one bridge to the 1 at row 4, column 3.

  23. The 5 at row 4, column 5 needs 1 more, and only the 4 at row 4, column 9 can still take bridges. So it gets a second bridge to the 4 at row 4, column 9.

  24. The 4 at row 7, column 3 needs 1 more, and only the 5 at row 9, column 3 can still take bridges. So it gets a second bridge to the 5 at row 9, column 3.

  25. The 2 at row 9, column 1 needs 1 more, and only the 5 at row 9, column 3 can still take bridges. So it gets one bridge to the 5 at row 9, column 3.

  26. The bridge between the 5 at row 7, column 8 and the 2 at row 10, column 8 blocks the way from the 3 at row 9, column 9 to the 2 at row 9, column 7. The 3 at row 9, column 9 needs 3, one less than the 4 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 6 at row 9, column 12.

  27. Suppose the 6 at row 4, column 12 and the 3 at row 4, column 14 shared only one bridge. Following the rules from there breaks one, so they share two.

  28. The 2 at row 9, column 14 needs 2, one less than the 3 its neighbors could take. Even if the others give all they can, it still gets at least one bridge to the 6 at row 9, column 12.

  29. Suppose the 5 at row 9, column 3 and the 2 at row 9, column 5 shared no bridge. Following the rules from there breaks one, so they share at least one.

  30. The 5 at row 14, column 3 needs 1 more, and only the 5 at row 14, column 7 can still take bridges. So it gets a second bridge to the 5 at row 14, column 7.

  31. The bridge between the 4 at row 7, column 3 and the 5 at row 7, column 8 blocks the way from the 2 at row 9, column 7 to the 1 at row 6, column 7. The 2 at row 9, column 7 needs 1 more, and only the 5 at row 14, column 7 can still take bridges. So it gets a second bridge to the 5 at row 14, column 7.

  32. The 5 at row 14, column 9 needs 5, and its neighbors can take 5 at most. So it takes all of them: a second bridge to the 2 at row 11, column 9 and a second bridge to the 4 at row 14, column 12.

  33. The 3 at row 9, column 9 needs 3, and its neighbors can take 3 at most. So it takes all of them: one bridge to the 4 at row 4, column 9 and a second bridge to the 6 at row 9, column 12.

  34. The 6 at row 4, column 12 needs 1 more, and only the 3 at row 6, column 12 can still take bridges. So it gets a second bridge to the 3 at row 6, column 12.

  35. The 6 at row 9, column 12 needs 6, and its neighbors can take 6 at most. So it takes all of them: a second bridge to the 2 at row 9, column 14 and one bridge to the 4 at row 14, column 12.

  36. The 1 at row 11, column 14 needs 1 more, and only the 2 at row 14, column 14 can still take bridges. So it gets one bridge to the 2 at row 14, column 14.
