About Zip #521
- Zip #521 is a 7×7 grid with 12 numbered checkpoints and 2 walls.
- The path runs from 1 to 12 and must cover all 49 squares.
- It has 12 checkpoints, more than the average of 11.0 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, R1C7, R7C1, and R7C7 have just two neighbors each, so all their links are forced: R1C1 links to R2C1 and R1C2; R1C7 links to R1C6 and R2C7; R7C1 links to R6C1 and R7C2; R7C7 links to R6C7 and R7C6.
- Walls leave R4C4 only two open sides, which fixes both links: R4C4 links to R5C4 and R4C5.
