Bridges of the week: week 5

The full logical solve of the hard Bridges for September 29 to October 5, 2026, 14 × 14. 40 steps, 5 techniques, no guessing. Step through it, or jump to any step below.

Island needs every bridge. The 3 at row 1, column 7 needs 3, and its neighbors can take 3 at most. So it takes all of them: one bridge to the 1 at row 1, column 9 and two bridges to the 5 at row 3, column 7.
Step 1 of 40

Every step

  1. The 3 at row 1, column 7 needs 3, and its neighbors can take 3 at most. So it takes all of them: one bridge to the 1 at row 1, column 9 and two bridges to the 5 at row 3, column 7.

  2. The 4 at row 1, column 14 needs 4, and its neighbors can take 4 at most. So it takes all of them: two bridges to the 2 at row 1, column 12 and two bridges to the 5 at row 7, column 14.

  3. The 1 at row 2, column 13 needs 1 more, and only the 3 at row 2, column 11 can still take bridges. So it gets one bridge to the 3 at row 2, column 11.

  4. The 2 at row 8, column 3 needs 2 more, and only the 4 at row 8, column 5 can still take bridges. So it gets two bridges to the 4 at row 8, column 5.

  5. The 4 at row 8, column 5 needs 2 more, and only the 4 at row 8, column 11 can still take bridges. So it gets two bridges to the 4 at row 8, column 11.

  6. The 2 at row 2, column 2 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 5 at row 5, column 2.

  7. The 3 at row 2, column 11 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 4 at row 6, column 11.

  8. The 3 at row 3, column 4 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 5 at row 3, column 7 and at least one bridge to the 6 at row 5, column 4.

  9. The 5 at row 5, column 2 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 6 at row 5, column 4 and at least one bridge to the 5 at row 10, column 2.

  10. The 6 at row 5, column 4 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 3 at row 7, column 4.

  11. The 2 at row 6, column 8 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 6, column 11.

  12. The 5 at row 7, column 14 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 7, column 12 and at least one bridge to the 4 at row 10, column 14.

  13. The 5 at row 10, column 2 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 10, column 7 and at least one bridge to the 3 at row 13, column 2.

  14. The 5 at row 10, column 11 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 8, column 11, at least one bridge to the 4 at row 10, column 7, and at least one bridge to the 4 at row 10, column 14.

  15. The 3 at row 13, column 2 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 2 at row 13, column 6.

  16. The 2 at row 13, 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 10, column 14.

  17. The 3 at row 14, 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 3 at row 11, column 9 and at least one bridge to the 2 at row 14, column 7.

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

  19. The bridge between the 3 at row 2, column 11 and the 4 at row 6, column 11 blocks the way from the 1 at row 3, column 9 to the 1 at row 3, column 12. The 1 at row 3, column 9 needs 1 more, and only the 5 at row 3, column 7 can still take bridges. So it gets one bridge to the 5 at row 3, column 7.

  20. The 1 at row 3, column 12 needs 1 more, and only the 4 at row 7, column 12 can still take bridges. So it gets one bridge to the 4 at row 7, column 12.

  21. The bridge between the 3 at row 1, column 7 and the 5 at row 3, column 7 blocks the way from the 1 at row 2, column 8 to the 2 at row 2, column 2. The 1 at row 2, column 8 needs 1 more, and only the 3 at row 2, column 11 can still take bridges. So it gets one bridge to the 3 at row 2, column 11.

  22. The 2 at row 6, column 8 needs 1 more, and only the 4 at row 6, column 11 can still take bridges. So it gets a second bridge to the 4 at row 6, column 11.

  23. The 4 at row 6, column 11 needs 1 more, and only the 4 at row 8, column 11 can still take bridges. So it gets one bridge to the 4 at row 8, column 11.

  24. The 5 at row 10, column 11 needs 5, and its neighbors can take 5 at most. So it takes all of them: a second bridge to the 4 at row 10, column 7 and a second bridge to the 4 at row 10, column 14.

  25. The 5 at row 7, column 14 needs 1 more, and only the 4 at row 7, column 12 can still take bridges. So it gets a second bridge to the 4 at row 7, column 12.

  26. The 2 at row 13, column 14 needs 1 more, and only the 1 at row 13, column 10 can still take bridges. So it gets one bridge to the 1 at row 13, column 10.

  27. The bridge between the 4 at row 8, column 5 and the 4 at row 8, column 11 blocks the way from the 1 at row 5, column 6 to the 3 at row 11, column 6.

  28. The bridge between the 4 at row 6, column 11 and the 4 at row 8, column 11 blocks the way from the 4 at row 7, column 12 to the 2 at row 7, column 7. The 4 at row 7, column 12 needs 1 more, and only the 1 at row 9, column 12 can still take bridges. So it gets one bridge to the 1 at row 9, column 12.

  29. The 1 at row 11, column 12 needs 1 more, and only the 3 at row 11, column 9 can still take bridges. So it gets one bridge to the 3 at row 11, column 9.

  30. The 3 at row 11, column 6 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 2 at row 11, column 4.

  31. The bridge between the 2 at row 8, column 3 and the 4 at row 8, column 5 blocks the way from the 2 at row 11, column 4 to the 3 at row 7, column 4.

  33. Suppose the 3 at row 3, column 4 and the 5 at row 3, column 7 shared two bridges. Following the rules from there breaks one, so they don’t. The 3 at row 3, column 4 needs 1 more, and only the 6 at row 5, column 4 can still take bridges. So it gets a second bridge to the 6 at row 5, column 4.

  34. The 5 at row 3, column 7 needs 1 more, and only the 2 at row 7, column 7 can still take bridges. So it gets one bridge to the 2 at row 7, column 7.

  35. The 3 at row 7, column 4 needs 1 more, and only the 6 at row 5, column 4 can still take bridges. So it gets a second bridge to the 6 at row 5, column 4.

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

  37. Suppose the 5 at row 10, column 2 and the 4 at row 10, column 7 shared two bridges. Following the rules from there breaks one, so they don’t.
