Zip #34 was the 7×7 medium board of Thursday, October 29, 2026: 9 numbered dots, 2 walls, and one path that visits all 49 cells in order. Our solver, a line-for-line port of the app's, needed 769 search nodes to prove the path unique, which puts the board at 5 of 5 on the difficulty scale. Along the answer, 54% of the moves had only one legal continuation; the other 22 steps offered a real choice, and those are where you have to look ahead. The path turns at 51% of its cells, and its longest straight run is 7 cells. The longest leg, between two consecutive dots, is 12 cells.
