Poople #585 SOFA Answer

Poople #585 started at SOFA on March 22, 2027. Its selective opening changes letters in the sequence A>T, S>L, F>O, T>P, L>P, with 2 par-preserving first moves.

Archive value: this is not a copied daily page. Its tables are calculated for SOFA, including 4 legal openings and route signature 4-1-3-4-1.

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 S-O-F-A. 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.

What changes at every step

  1. Step 1SOFA -> SOFT

    Tile 4 changes A to T; the move is sideways by letter shape. SOFT has 5 legal neighbors, 2 shortest continuations, and 4 moves remaining. Other legal exits from SOFA include SOMA, SODA, SOBA.

  2. Step 2SOFT -> LOFT

    Tile 1 changes S to L; the move is sideways by letter shape. LOFT has 6 legal neighbors, 1 shortest continuation, and 3 moves remaining. Other legal exits from SOFT include SOOT, SORT, SIFT.

  3. Step 3LOFT -> LOOT

    Tile 3 changes F to O; the move is closer by letter shape. LOOT has 16 legal neighbors, 1 shortest continuation, and 2 moves remaining. Other legal exits from LOFT include LOST, LOUT, LEFT, LIFT.

  4. Step 4LOOT -> LOOP

    Tile 4 changes T 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 LOOT include LOOK, BOOT, LOOM, LOON.

  5. Step 5LOOP -> 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?

SOFA has 4 legal one-letter neighbors. SOFT, SOMA keep the route at 5 moves, while sampled detours begin SODA (+1), SOBA (+1).

SOFA opening fingerprint

SOFA groups its legal first moves as tile 3: SOMA, SODA, SOBA; tile 4: SOFT. Two moves from the start, 12 off-route words are reachable; the nearest sampled frontier is COMA, SOME, SOOT, BOBA, CODA, SOBS, SODS, SOMA, SORT, SIFT, SOBA, SODA.

Graph reading

LOFT is the narrowest displayed bridge

After SOFT becomes LOFT, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as SOOT, SORT, SIFT 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.
