Choose how much to reveal

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

What changes at every step

Step 1TACT -> TACK

Tile 4 changes T to K; the move is sideways by letter shape. TACK has 16 legal neighbors, 4 shortest continuations, and 5 moves remaining. Other legal exits from TACT include TART, TAUT, FACT, PACT.
Step 2TACK -> LACK

Tile 1 changes T to L; the move is sideways by letter shape. LACK has 15 legal neighbors, 1 shortest continuation, and 4 moves remaining. Other legal exits from TACK include BACK, HACK, TOCK, TALK.
Step 3LACK -> LOCK

Tile 2 changes A to O; the move is closer by letter shape. LOCK has 18 legal neighbors, 1 shortest continuation, and 3 moves remaining. Other legal exits from LACK include BACK, LUCK, HACK, LICK.
Step 4LOCK -> LOOK

Tile 3 changes C to O; the move is closer by letter shape. LOOK has 13 legal neighbors, 1 shortest continuation, and 2 moves remaining. Other legal exits from LOCK include COCK, BOCK, HOCK, ROCK.
Step 5LOOK -> LOOP

Tile 4 changes K to P; the move is closer by letter shape. LOOP has 9 legal neighbors, 1 shortest continuation, and 1 move remaining. Other legal exits from LOOK include BOOK, COOK, HOOK, LOOM.
Step 6LOOP -> POOP

Tile 1 changes L to P; the move is closer by letter shape. POOP has 11 legal neighbors, target reached, and 0 moves remaining. Other legal exits from LOOP include COOP, HOOP, BOOP, GOOP.

Opening decision

Which first moves preserve par?

TACT has 6 legal one-letter neighbors. TACK, TART, TAUT keep the route at 6 moves, while sampled detours begin FACT (+1), PACT (+1), TACO (+1).

Graph reading

LOOP is the narrowest displayed bridge

After LOOK becomes LOOP, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as BOOK, COOK, HOOK, LOOM show what the route declined.

Direct-shape gains: 4
Sideways steps: 2
Temporary shape detours: 0
Steps touching a vowel: 2

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.
