About Zip #545
- Zip #545 is a 7×7 grid with 8 numbered checkpoints and 10 walls.
- The path runs from 1 to 8 and must cover all 49 squares.
- LinkedIn rates it Hard.
- It has 8 checkpoints, fewer than the average of 11.4 across the previous 7 puzzles.
- Each square is entered once and left once, so it needs two path links; only the two ends, checkpoints 1 and 8, need just one.
- The corners R1C1, R1C7, R7C1, and R7C7 have just two neighbors each, so all their links are forced: R1C1 links to R2C1 and R1C2; R1C7 links to R1C6 and R2C7; R7C1 links to R6C1 and R7C2; R7C7 links to R6C7 and R7C6.
- Walls leave R1C4 and R4C3 only two open sides each, which fixes their links: R1C4 links to R1C3 and R1C5; R4C3 links to R4C2 and R4C4; Checkpoint 8 at R2C4 is an end of the path with one open side, so R2C4 links to R3C4.
