About Zip #557
- Zip #557 is a 7×7 grid with 10 numbered checkpoints and 12 walls.
- The path runs from 1 to 10 and must cover all 49 squares.
- LinkedIn rates it Hard.
- It has 10 checkpoints, more than the average of 9.1 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 10, need just one.
- The corners R1C1, R1C7, and R7C1 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.
- Walls leave R1C2, R2C1, and checkpoint 5 at R2C2 only two open sides each, which fixes their links: R1C2 links to R1C1 and R1C3; R2C1 links to R1C1 and R3C1; R2C2 links to R3C2 and R2C3.
- Checkpoints 4 and 9 are not consecutive, so they cannot be linked directly, which leaves checkpoint 4 at R2C4 and checkpoint 9 at R2C5 with only two exits each: R2C4 links to R1C4 and R2C3; R2C5 links to R1C5 and R2C6.
