About Zip #543
- Zip #543 is an 8×8 grid with 20 numbered checkpoints and 8 walls.
- The path runs from 1 to 20 and must cover all 64 squares.
- LinkedIn rates it Hard.
- It has 20 checkpoints, more than the average of 10.4 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 20, need just one.
- The corners R1C1, R1C8, R8C1, and R8C8 have just two neighbors each, so all their links are forced: R1C1 links to R2C1 and R1C2; R1C8 links to R1C7 and R2C8; R8C1 links to R7C1 and R8C2; R8C8 links to R7C8 and R8C7.
- Walls leave R3C3, R3C6, and R6C3 only two open sides each, which fixes their links: R3C3 links to R4C3 and R3C4; R3C6 links to R3C5 and R4C6; R6C3 links to R5C3 and R6C4.
- Checkpoints 4 and 13 are not consecutive, so they cannot be linked directly, which leaves checkpoint 4 at R1C4 and checkpoint 13 at R1C5 with only two exits each: R1C4 links to R1C3 and R2C4; R1C5 links to R2C5 and R1C6.
