About Zip #489
- Zip #489 is an 8×8 grid with 10 numbered checkpoints and 18 walls.
- The path runs from 1 to 10 and must cover all 64 squares.
- Each square is entered once and left once, so it needs two path links; only the two ends, checkpoints 1 and 10, 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 R1C2, R1C4, and R1C6 only two open sides each, which fixes their links: R1C2 links to R1C1 and R1C3; R1C4 links to R1C3 and R1C5; R1C6 links to R1C5 and R1C7.
- Checkpoints 5 and 9 are not consecutive, so they cannot be linked directly, which leaves checkpoint 9 at R5C3 with only two exits: R5C3 links to R4C3 and R5C2.
