Word Ladder Rules:
* You start with a given word (in this case, "RUB-A-DUB-DUB").
* You change one letter at a time to form a new valid English word.
* You continue this process until you reach a target word.
Let's make a word ladder!
Unfortunately, "RUB-A-DUB-DUB" isn't a single word. It's a phrase. To make a word ladder, we need a single starting word. Let's try "RUB" as our starting word and "DUB" as our target. Here's a possible solution:
1. RUB
2. RUG
3. DUG
4. DUB
Let me know if you want to try a different starting word, target word, or phrase!
