The hint describes the move without naming the word. The full route stays closed until you ask for it.

Reveal a direction, not a word

The current row reads B-I-L-E. Change position 4 and keep positions 1, 2, 3 fixed. Look for a vowel-to-consonant change. 2 different first moves preserve the shortest length.

Graph reading

POOL is the narrowest displayed bridge

After POLL becomes POOL, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as ROLL, TOLL, PULL, DOLL show what the route declined.

Direct-shape gains: 4
Sideways steps: 1
Temporary shape detours: 0
Steps touching a vowel: 3

How these figures were calculated

Poople recomputes adjacency and distance from the accepted 2,398-word graph. "Shortest routes" counts every path that lowers the remaining distance by one at each move; it is not a guess based on page text or player scores.

The displayed answer is one shortest route selected from that graph. Community scores and notes are kept separate because they describe player activity, not the mathematical route.
