About Zip #523
- Zip #523 is an 8×8 grid with 16 numbered checkpoints and 0 walls.
- The path runs from 1 to 16 and must cover all 64 squares.
- LinkedIn rates it Hard.
- It has 16 checkpoints, more than the average of 10.7 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 16, 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 3 and 6 are not consecutive, so they cannot be linked directly and checkpoints 3 and 8 are not consecutive, so they cannot be linked directly, which leaves checkpoint 3 at R2C3 with only two exits: R2C3 links to R1C3 and R2C2.
- Checkpoints 2 and 10 are not consecutive, so they cannot be linked directly and checkpoints 10 and 13 are not consecutive, so they cannot be linked directly, which leaves checkpoint 10 at R6C7 with only two exits: R6C7 links to R7C7 and R6C8.
