Stepwise
Change one letter per step to turn the start word into the end word.
Climb from the top word to the bottom word, changing exactly one letter at each step. Every rung along the way must be a real word.
The start and end words are locked in place. Tap a shuffled rung, then tap another to swap them, until every consecutive pair differs by exactly one letter.
Letters that changed from the word above are highlighted, so you can check your work as you go.
