Where to start
This board has 3 openings where only a single route is possible, so those numbers are forced:
- The 16 in row 3 and the 18 in row 3 are exactly 2 steps apart, and only one 2-step route connects them — so 17 is forced.
- The 64 in row 9 and the 66 in row 9 are exactly 2 steps apart, and only one 2-step route connects them — so 65 is forced.
- The 71 in row 5 and the 73 in row 3 are exactly 2 steps apart, and only one 2-step route connects them — so 72 is forced.
