Word Ladder

A word ladder is a path between two words. Change one letter at each step, keeping every entry a valid four-letter word, until you reach the target. A short route can take a little planning: a word that looks closer to the target is not always the best next move. This free edition includes a Daily puzzle and Practice from a fixed collection, with Hint, Undo and result sharing. No account is needed to play. The original website also lets you send a fixed challenge link so friends can independently solve the same puzzle; it is not live multiplayer. Original website: https://getwordladder.com/
Fixed challenge on the original website: https://getwordladder.com/?p=v1-001 AI assisted code, copy and the selection of candidate puzzle words and endpoint pairs. Deterministic graph checks validated the fixed catalog. There is no live AI service during play. Accepted words come from the public-domain ENABLE word list; it includes obscure and potentially offensive entries, so the full input dictionary is not a curated children's vocabulary. Made by Rocky. The creator tested several full games on a real phone without encountering problems; this is not a claim of testing every device or browser. Show Less
