About Zip #503
- Zip #503 is an 8×8 grid with 8 numbered checkpoints and 16 walls.
- The path runs from 1 to 8 and must cover all 64 squares.
- It has 8 checkpoints, fewer 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 8, 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, R3C4, and R4C3 only two open sides each, which fixes their links: R3C3 links to R3C2 and R3C4; R3C4 links to R3C3 and R3C5; R4C3 links to R4C2 and R4C4.
- Checkpoints 3 and 7 are not consecutive, so they cannot be linked directly, which leaves checkpoint 3 at R2C3 and checkpoint 7 at R2C4 with only two exits each: R2C3 links to R1C3 and R2C2; R2C4 links to R1C4 and R2C5.
