Word Ladder Patterns: Every Door to POOP

Every route ends at one of these doors

Because the Poople target never changes, every solved ladder makes its final move through one of a fixed set of words. In the current dictionary exactly 19 words differ from POOP by a single letter. This page maps those doors and the graph behind them, using the same generated data that validates guesses in the game.

Knowing the doors changes how the endgame feels. Instead of hunting blindly for a finishing move, you can steer the chain toward a shape that is one letter from the target and let the last step take care of itself.

The doors, ranked by traffic

The table lists each door with the position it changes and how many two-move words connect through it. A door that serves more two-move words is reachable from more of the graph, so routes funnel through it more often.

Raw traffic is not the whole story. POOS and POOT serve the most two-move words, but they are informal or rare entries. The doors most players actually recognize — POOL, POOR, LOOP, COOP, and PROP — carry plenty of traffic of their own, and the route solver prefers more familiar words when equal-length paths tie.

Four pattern families

The 19 doors sort into four families by which letter they change. The first-letter family (•OOP) is the widest: COOP, GOOP, HOOP, LOOP, MOOP, NOOP, ROOP, SOOP, and YOOP all reach the target by restoring the P. The last-letter family (POO•) has six members: POOH, POOK, POOL, POOR, POOS, and POOT. The middle positions are scarce — only PLOP and PROP change the second letter, and only POEP and POMP change the third.

The practical reading: double-O words with a rhyming -OOP ending are the broadest highway to the target, and locking the OO pair early usually matters more than finding the right first letter. When a route reaches any -OOP or POO- shape, the finish is one move away.

• •OOP — nine doors, the widest family; restore the initial P to finish.
• POO• — six doors; POOL and POOR are the most familiar of all nineteen.
• P•OP and PO•P — two doors each; useful but easy to overlook.

How far is the rest of the dictionary?

Breadth-first search from POOP assigns every connected word a shortest distance. The distribution is heavily weighted toward the middle: most of the graph sits four or five moves out, which is exactly the range Poople uses for Daily starts.

The far edge is tiny and strange. Only seven words need ten or more moves, and the two most remote words in the current snapshot — UNAU and UPGO, both 11 moves out — are obscure enough that they serve as bridge words only, never as public starts.

Hub words keep routes alive

A word's neighbor count measures how many one-letter moves it offers. High-degree hub words act as junctions: passing through one keeps several escape routes open if your planned line goes wrong. The busiest words in the current graph offer nearly forty moves each.

Connectivity also explains why the endgame feels different from the opening. Words four moves or closer to the target average around sixteen neighbors in the current snapshot, but the average falls sharply past five moves — long-route territory is genuinely narrower, not just less familiar.

Using the map in play

In the opening, move toward common letters and keep options wide: hub-shaped words with common consonant frames rarely trap a route. In the middle game, aim for the OO pair or a P in first position, whichever is closer. In the endgame, check the door table — if your current word is two moves from any door, the route is effectively finished.

The archive is the companion data set: every published Daily entry records its verified shortest route, so you can check which doors real puzzles actually used.

Method and limitations

All numbers on this page are computed at build time from the same generated word graph that runs the game: two words are neighbors when they differ in exactly one position, distances come from breadth-first search, and no figures are estimated from traffic or third-party sources. The tables update automatically whenever the dictionary is regenerated.

Neighbor counts describe the current dictionary, not English as a whole; a different word list would draw a slightly different map. If a word, count, or pattern here looks wrong, send the word and this page's URL to info@poople.org and it will be checked against the generated graph before the data is revised.

• Counts are generated from repository data at build time, not analytics.
• Prose observations reference the snapshot named in the updated date.
• Dictionary regeneration can add or remove doors; tables follow the data.
