Rules

Turn the start word into the target word. Each move changes exactly one letter (no adding, removing or reordering) and must produce a valid English word: {"type": "submit_word", "args": {"word": "<word>"}}. Use {"type": "undo"} to remove the last word from your ladder. par is the length of the shortest possible ladder. Score (0-100): 100 * par / words submitted (undone words count too), minus 5 points per invalid attempt. Unsolved games score 0. The game ends when you reach the target, after 5 invalid attempts, or after 50 submitted words.
