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

What changes at every step

  1. Step 1SURF -> SURE

    Tile 4 changes F to E; the move is sideways by letter shape. SURE has 8 legal neighbors, 2 shortest continuations, and 5 moves remaining. Other legal exits from SURF include TURF, SERF.

  2. Step 2SURE -> SORE

    Tile 2 changes U to O; the move is closer by letter shape. SORE has 16 legal neighbors, 2 shortest continuations, and 4 moves remaining. Other legal exits from SURE include PURE, CURE, LURE, SIRE.

  3. Step 3SORE -> SOME

    Tile 3 changes R to M; the move is sideways by letter shape. SOME has 9 legal neighbors, 1 shortest continuation, and 3 moves remaining. Other legal exits from SORE include PORE, MORE, SORT, CORE.

  4. Step 4SOME -> POME

    Tile 1 changes S to P; the move is closer by letter shape. POME has 11 legal neighbors, 1 shortest continuation, and 2 moves remaining. Other legal exits from SOME include HOME, COME, DOME, TOME.

  5. Step 5POME -> POMP

    Tile 4 changes E to P; the move is closer by letter shape. POMP has 6 legal neighbors, 1 shortest continuation, and 1 move remaining. Other legal exits from POME include HOME, COME, POLE, POPE.

  6. Step 6POMP -> POOP

    Tile 3 changes M to O; the move is closer by letter shape. POOP has 11 legal neighbors, target reached, and 0 moves remaining. Other legal exits from POMP include PUMP, COMP, PIMP, ROMP.

Opening decision

Which first moves preserve par?

SURF has 3 legal one-letter neighbors, but only SURE keeps the route at 6 moves. Nearby detours begin TURF (+1), SERF (+1).

SURF opening fingerprint

SURF groups its legal first moves as tile 1: TURF; tile 2: SERF; tile 4: SURE. Two moves from the start, 11 off-route words are reachable; the nearest sampled frontier is PURE, CURE, JURE, LURE, SERE, SIRE, TURN, SELF, SERA, TUFF, TURD.

Graph reading

POMP is the narrowest displayed bridge

After POME becomes POMP, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as HOME, COME, POLE, POPE 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.
