The route reaches the final bridge BOOP, then changes letter 1 to reach POOP. Its 6 moves match the dictionary distance calculated from the target.
Compare the first move
DUDE has 6 accepted one-letter neighbors in this vocabulary. 4 can begin a shortest route: DUDS, DUKE, DUNE, DUPE. Each leaves exactly 5 moves to POOP.
Some longer openings are NUDE (7 total moves), RUDE (7 total moves). These counts include the first move from DUDE.
Similarity can be misleading
DUDE → DUDS, DUDS → BUDS do not reduce the number of letters that differ from POOP, but still belong to a minimum-move route. Reachable word connections matter more than matching letters immediately.
If a word is rejected
Enter the last accepted word in the solver, exclude the rejected word, and recalculate. A shorter dictionary can require more moves. Read the strategy guide for a worked detour example.
