The first move matters.
FUEL has 4 valid one-letter neighbors in this dictionary. 2 of them can begin a shortest path:
FEELFULL
Each of these leaves 4 moves to POOP. The other 2 neighbors are valid moves too, but cannot reach the target in the minimum from this starting word.
Follow the changes
The highlighted letter beside each step shows exactly which position changed. The sequence above is computed from the same dictionary as the game. Other shortest routes can take different intermediate words.
