Poople #355 REIN Answer

Poople #355 started at REIN on August 4, 2026. Its narrow opening changes letters in the sequence E>A, R>L, A>O, I>O, N>P, L>P, with 1 par-preserving first moves.

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

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

What changes at every step

  1. Step 1REIN -> RAIN

    Tile 2 changes E to A; the move is sideways by letter shape. RAIN has 10 legal neighbors, 1 shortest continuation, and 5 moves remaining. Other legal exits from REIN include VEIN, RUIN.

  2. Step 2RAIN -> LAIN

    Tile 1 changes R to L; the move is sideways by letter shape. LAIN has 10 legal neighbors, 1 shortest continuation, and 4 moves remaining. Other legal exits from RAIN include MAIN, PAIN, GAIN, RAIL.

  3. Step 3LAIN -> LOIN

    Tile 2 changes A to O; the move is closer by letter shape. LOIN has 5 legal neighbors, 1 shortest continuation, and 3 moves remaining. Other legal exits from LAIN include MAIN, PAIN, GAIN, LAID.

  4. Step 4LOIN -> LOON

    Tile 3 changes I to O; the move is closer by letter shape. LOON has 13 legal neighbors, 1 shortest continuation, and 2 moves remaining. Other legal exits from LOIN include LOAN, JOIN, COIN.

  5. Step 5LOON -> LOOP

    Tile 4 changes N 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 LOON include LOOK, LOOM, BOON, LOOT.

  6. 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?

REIN has 3 legal one-letter neighbors, but only RAIN keeps the route at 6 moves. Nearby detours begin VEIN (+1), RUIN (+1).

REIN opening fingerprint

REIN groups its legal first moves as tile 1: VEIN; tile 2: RAIN, RUIN. Two moves from the start, 9 off-route words are reachable; the nearest sampled frontier is FAIN, GAIN, MAIN, PAIN, RAID, RAIL, VAIN, RUIN, VEIL.

Graph reading

LOIN is the narrowest displayed bridge

After LAIN becomes LOIN, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as MAIN, PAIN, GAIN, LAID 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.
