Where to start
This board has 3 openings where only a single route is possible, so those numbers are forced:
- The 22 in row 5 and the 24 in row 3 are exactly 2 steps apart, and only one 2-step route connects them — so 23 is forced.
- The 43 in row 1 and the 45 in row 3 are exactly 2 steps apart, and only one 2-step route connects them — so 44 is forced.
- The 52 in row 5 and the 54 in row 5 are exactly 2 steps apart, and only one 2-step route connects them — so 53 is forced.
