Zip #41 was the 7×7 medium board of Thursday, November 5, 2026: 10 numbered dots, 5 walls, and one path that visits all 49 cells in order. Our solver, a line-for-line port of the app's, needed 620 search nodes to prove the path unique, which puts the board at 5 of 5 on the difficulty scale. Along the answer, 56% of the moves had only one legal continuation; the other 21 steps offered a real choice, and those are where you have to look ahead. The path turns at 43% of its cells, and its longest straight run is 7 cells. The longest leg, between two consecutive dots, is 29 cells.

Where the choices are: step 1 at row 1, column 5 (2 ways), step 2 at row 1, column 4 (2 ways), step 4 at row 2, column 3 (2 ways), step 5 at row 3, column 3 (2 ways), step 10 at row 4, column 5 (2 ways) and step 11 at row 4, column 4 (2 ways) and 15 more. Everywhere else only one move keeps the board solvable.

Zip #41 solution

The number in each cell is its position on the path; the dots keep their own numbers and are highlighted.
