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 D-U-T-Y. Change position 3 and keep positions 1, 2, 4 fixed. Look for a consonant-to-consonant change. Only one first move preserves the shortest length.

What changes at every step

  1. Step 1DUTY -> DULY

    Tile 3 changes T to L; the move is sideways by letter shape. DULY has 2 legal neighbors, 1 shortest continuation, and 5 moves remaining. DUTY has no additional off-route exit in the sampled branch set.

  2. Step 2DULY -> DULL

    Tile 4 changes Y to L; the move is sideways by letter shape. DULL has 15 legal neighbors, 2 shortest continuations, and 4 moves remaining. DULY has no additional off-route exit in the sampled branch set.

  3. Step 3DULL -> PULL

    Tile 1 changes D to P; the move is closer by letter shape. PULL has 15 legal neighbors, 1 shortest continuation, and 3 moves remaining. Other legal exits from DULL include DOLL, FULL, NULL, DELL.

  4. Step 4PULL -> POLL

    Tile 2 changes U to O; the move is closer by letter shape. POLL has 12 legal neighbors, 1 shortest continuation, and 2 moves remaining. Other legal exits from PULL include PILL, PULP, PALL, FULL.

  5. Step 5POLL -> POOL

    Tile 3 changes L to O; the move is closer by letter shape. POOL has 8 legal neighbors, 1 shortest continuation, and 1 move remaining. Other legal exits from POLL include ROLL, TOLL, PILL, DOLL.

  6. Step 6POOL -> POOP

    Tile 4 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 POOL include POOR, POOF, TOOL, COOL.

Opening decision

Which first moves preserve par?

DUTY has 1 legal one-letter neighbors, but only DULY keeps the route at 6 moves. Nearby detours begin outside the sampled opening set.

Graph reading

DULY is the narrowest displayed bridge

After DUTY becomes DULY, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as no sampled off-route word show what the route declined.

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.
