About Zip #520
- Zip #520 is a 7×7 grid with 8 numbered checkpoints and 20 walls.
- The path runs from 1 to 8 and must cover all 49 squares.
- It has 8 checkpoints, fewer than the average of 11.6 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, 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 checkpoint 4 at R1C3, R1C6, and R2C1 only two open sides each, which fixes their links: R1C3 links to R1C2 and R1C4; R1C6 links to R1C5 and R1C7; R2C1 links to R1C1 and R3C1.
