Where to start
This board has 3 openings where only a single route is possible, so those numbers are forced:
- The 25 in row 2 and the 30 in row 1 are exactly 5 steps apart, and only one 5-step route connects them — so 26, 27, 28 and 29 are forced.
- The 50 in row 7 and the 53 in row 8 are exactly 3 steps apart, and only one 3-step route connects them — so 51 and 52 are forced.
- The 35 in row 6 and the 37 in row 4 are exactly 2 steps apart, and only one 2-step route connects them — so 36 is forced.
