Where to start
This board has 2 openings where only a single route is possible, so those numbers are forced:
- The 6 in row 4 and the 8 in row 2 are exactly 2 steps apart, and only one 2-step route connects them — so 7 is forced.
- The 17 in row 8 and the 19 in row 8 are exactly 2 steps apart, and only one 2-step route connects them — so 18 is forced.
