About Zip #509
- Zip #509 is an 8×8 grid with 12 numbered checkpoints and 12 walls.
- The path runs from 1 to 12 and must cover all 64 squares.
- LinkedIn rates it Hard.
- It has 12 checkpoints, more than the average of 10.9 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 12, 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 10 and 12 are not consecutive, so they cannot be linked directly, which leaves checkpoint 10 at R2C8 with only two exits: R2C8 links to R1C8 and R3C8.
