Where to start
This board has 2 openings where only a single route is possible, so those numbers are forced:
- The 39 in row 4 and the 42 in row 2 are exactly 3 steps apart, and only one 3-step route connects them — so 40 and 41 are forced.
- The 52 in row 4 and the 54 in row 5 are exactly 2 steps apart, and only one 2-step route connects them — so 53 is forced.
