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-P-S. Change position 2 and keep positions 1, 3, 4 fixed. Look for a vowel-to-vowel change. 4 different first moves preserve the shortest length.

What changes at every step

Step 1REPS -> RAPS

Tile 2 changes E to A; the move is sideways by letter shape. RAPS has 21 legal neighbors, 2 shortest continuations, and 5 moves remaining. Other legal exits from REPS include REDS, REGS, PEPS, REFS.
Step 2RAPS -> CAPS

Tile 1 changes R to C; the move is sideways by letter shape. CAPS has 23 legal neighbors, 1 shortest continuation, and 4 moves remaining. Other legal exits from RAPS include RAMS, MAPS, RATS, RAYS.
Step 3CAPS -> COPS

Tile 2 changes A to O; the move is closer by letter shape. COPS has 20 legal neighbors, 1 shortest continuation, and 3 moves remaining. Other legal exits from CAPS include CATS, CAMS, CUPS, CANS.
Step 4COPS -> COOS

Tile 3 changes P to O; the move is closer by letter shape. COOS has 15 legal neighbors, 1 shortest continuation, and 2 moves remaining. Other legal exits from COPS include CONS, COWS, COTS, COGS.
Step 5COOS -> COOP

Tile 4 changes S to P; the move is closer by letter shape. COOP has 14 legal neighbors, 1 shortest continuation, and 1 move remaining. Other legal exits from COOS include COOL, COOK, BOOS, COOT.
Step 6COOP -> POOP

Tile 1 changes C to P; the move is closer by letter shape. POOP has 11 legal neighbors, target reached, and 0 moves remaining. Other legal exits from COOP include LOOP, HOOP, BOOP, GOOP.

Opening decision

Which first moves preserve par?

REPS has 9 legal one-letter neighbors. REDS, REGS, RAPS, PEPS keep the route at 6 moves, while sampled detours begin REFS (+1), RIPS (+1), RECS (+1), REVS (+1).

REPS opening fingerprint

REPS groups its legal first moves as tile 1: PEPS; tile 2: RAPS, RIPS; tile 3: REDS, REGS, REFS, RECS, REVS; tile 4: REPO. Two moves from the start, 60 off-route words are reachable; the nearest sampled frontier is BEDS, BEGS, PEES, POPS, RAMS, RODS, DAPS, GAPS, HAPS, HIPS, KEGS, LAPS, LEGS, LIPS, MAPS, MEDS, NAPS, PAPS, PEAS, PECS, PEGS, PENS, PETS, PEWS.

Graph reading

COOP is the narrowest displayed bridge

After COOS becomes COOP, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as COOL, COOK, BOOS, COOT show what the route declined.

Direct-shape gains: 4
Sideways steps: 2
Temporary shape detours: 0
Steps touching a vowel: 3

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.
