Where to start
This board has 2 openings where only a single route is possible, so those numbers are forced:
- The 1 in row 7 and the 4 in row 9 are exactly 3 steps apart, and only one 3-step route connects them — so 2 and 3 are forced.
- The 18 in row 5 and the 20 in row 3 are exactly 2 steps apart, and only one 2-step route connects them — so 19 is forced.
