Learn how a poople solver finds the shortest word ladder with a one-letter graph and breadth-first search.
A poople solver models every valid four-letter word as a node. It connects two nodes when exactly one letter changes, then searches outward from POOP until it reaches the daily start.
Breadth-first search explores all routes with one move, then two moves, then three. The first time it reaches the start word, that distance is the mathematical minimum for the current word list.
There may be several equally short routes. Any route that reaches POOP in the minimum number of accepted moves is a perfect solve.
The built-in hint keeps the game interactive by revealing only the distance and one next move. A full solver explanation is useful for learning the structure of word ladders without replacing the daily challenge.
