Poople #516 TREE Answer

Poople #516 started at TREE on January 12, 2027. Its narrow opening changes letters in the sequence T>F, R>L, E>O, E>P, F>P, L>O, with 1 par-preserving first moves.

Archive value: this is not a copied daily page. Its tables are calculated for TREE, including 5 legal openings and route signature 1-2-3-4-1-2.

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

What changes at every step

  1. Step 1TREE -> FREE

    Tile 1 changes T to F; the move is sideways by letter shape. FREE has 3 legal neighbors, 1 shortest continuation, and 5 moves remaining. Other legal exits from TREE include TRUE, TREK, THEE, TWEE.

  2. Step 2FREE -> FLEE

    Tile 2 changes R to L; the move is sideways by letter shape. FLEE has 8 legal neighbors, 1 shortest continuation, and 4 moves remaining. Other legal exits from FREE include FRET.

  3. Step 3FLEE -> FLOE

    Tile 3 changes E to O; the move is closer by letter shape. FLOE has 7 legal neighbors, 1 shortest continuation, and 3 moves remaining. Other legal exits from FLEE include FLEW, FLED, FLUE, FLEX.

  4. Step 4FLOE -> FLOP

    Tile 4 changes E to P; the move is closer by letter shape. FLOP has 9 legal neighbors, 1 shortest continuation, and 2 moves remaining. Other legal exits from FLOE include FLOW, FLOG, SLOE, ALOE.

  5. Step 5FLOP -> PLOP

    Tile 1 changes F to P; the move is closer by letter shape. PLOP has 11 legal neighbors, 1 shortest continuation, and 1 move remaining. Other legal exits from FLOP include SLOP, CLOP, GLOP, FLOW.

  6. Step 6PLOP -> POOP

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

Opening decision

Which first moves preserve par?

TREE has 5 legal one-letter neighbors, but only FREE keeps the route at 6 moves. Nearby detours begin TRUE (+2), TREK (+2), THEE (+2), TWEE (+2).

TREE opening fingerprint

TREE groups its legal first moves as tile 1: FREE; tile 2: THEE, TWEE; tile 3: TRUE; tile 4: TREK. Two moves from the start, 8 off-route words are reachable; the nearest sampled frontier is FRET, GHEE, THEN, WHEE, THEE, THEM, THEY, TWEE.

Graph reading

FREE is the narrowest displayed bridge

After TREE becomes FREE, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as TRUE, TREK, THEE, TWEE 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.
