How the ladder works.
You start with one four-letter word and aim for another. Each move changes exactly one letter, and every word along the way has to be a real one — no nonsense rungs. Type a word and press enter; if it doesn’t fit, it simply bounces back, no penalty. Reach the target in as few steps as you can — par is the shortest possible. Stuck? Take a hint (up to three) or undo your last rung. Your progress saves in the browser, so you can close the tab and finish later.
