About Zip #538
- Zip #538 is an 8×8 grid with 18 numbered checkpoints and 0 walls.
- The path runs from 1 to 18 and must cover all 64 squares.
- LinkedIn rates it Hard.
- It has 18 checkpoints, more than the average of 9.4 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 18, 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.
- Checkpoints 5 and 14 are not consecutive, so they cannot be linked directly and checkpoints 12 and 14 are not consecutive, so they cannot be linked directly, which leaves checkpoint 14 at R3C6 with only two exits: R3C6 links to R3C5 and R3C7.
- Checkpoints 8 and 11 are not consecutive, so they cannot be linked directly and checkpoints 4 and 8 are not consecutive, so they cannot be linked directly, which leaves checkpoint 8 at R6C5 with only two exits: R6C5 links to R6C4 and R6C6.
