Where to start
This board has 2 openings where only a single route is possible, so those numbers are forced:
- The 1 in row 3 and the 3 in row 2 are exactly 2 steps apart, and only one 2-step route connects them — so 2 is forced.
- The 22 in row 6 and the 24 in row 4 are exactly 2 steps apart, and only one 2-step route connects them — so 23 is forced.
