Turn the bottom word into the top word. Each rung changes exactly one letter and must be a real word.

Tap a letter of your current word, then tap its replacement on the keyboard. Wrong turn? Undo takes a rung back.

Par is the shortest possible climb. Match it with no hints for three stars.

Keyboard: 1 to 6 picks a letter, a letter key changes it, Backspace undoes, ? asks for a hint.
