Where to start
This board has 3 openings where only a single route is possible, so those numbers are forced:
- The 55 in row 7 and the 60 in row 2 are exactly 5 steps apart, and only one 5-step route connects them — so 56, 57, 58 and 59 are forced.
- The 16 in row 7 and the 19 in row 5 are exactly 3 steps apart, and only one 3-step route connects them — so 17 and 18 are forced.
- The 6 in row 9 and the 8 in row 9 are exactly 2 steps apart, and only one 2-step route connects them — so 7 is forced.
