About Zip #555
- Zip #555 is a 6×6 grid with 4 numbered checkpoints and 14 walls.
- The path runs from 1 to 4 and must cover all 36 squares.
- It has 4 checkpoints, fewer than the average of 9.4 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 4, need just one.
- The corners R1C1, R1C6, and R6C1 have just two neighbors each, so all their links are forced: R1C1 links to R2C1 and R1C2; R1C6 links to R1C5 and R2C6; R6C1 links to R5C1 and R6C2.
- Walls leave R1C2, checkpoint 3 at R1C4, and R2C1 only two open sides each, which fixes their links: R1C2 links to R1C1 and R1C3; R1C4 links to R1C3 and R1C5; R2C1 links to R1C1 and R3C1.
