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 K-E-E-N. Change position 4 and keep positions 1, 2, 3 fixed. Look for a consonant-to-consonant change. 2 different first moves preserve the shortest length.

What changes at every step

Step 1KEEN -> KEEP

Tile 4 changes N to P; the move is closer by letter shape. KEEP has 9 legal neighbors, 1 shortest continuation, and 4 moves remaining. Other legal exits from KEEN include PEEN, BEEN, TEEN, SEEN.
Step 2KEEP -> PEEP

Tile 1 changes K to P; the move is closer by letter shape. PEEP has 13 legal neighbors, 1 shortest continuation, and 3 moves remaining. Other legal exits from KEEP include DEEP, BEEP, WEEP, SEEP.
Step 3PEEP -> PREP

Tile 2 changes E to R; the move is sideways by letter shape. PREP has 4 legal neighbors, 1 shortest continuation, and 2 moves remaining. Other legal exits from PEEP include DEEP, PEER, PEEL, PEEK.
Step 4PREP -> PROP

Tile 3 changes E to O; the move is closer by letter shape. PROP has 11 legal neighbors, 1 shortest continuation, and 1 move remaining. Other legal exits from PREP include PREY, PREZ.
Step 5PROP -> POOP

Tile 2 changes R to O; the move is closer by letter shape. POOP has 11 legal neighbors, target reached, and 0 moves remaining. Other legal exits from PROP include PLOP, DROP, CROP, PROS.

Graph reading

PREP is the narrowest displayed bridge

After PEEP becomes PREP, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as DEEP, PEER, PEEL, PEEK 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.
