Microsoft Ultimate Word Games

Each Jumble puzzle has a bonus Jumble that is unlocked by finding words that correspond to the keys locking it. For this achievement, you'll need to strategically find all of the key words before completing the blue and purple words so that the bonus Jumble unlocks before you get either star for the blue or purple words. You could also use an anagram solver to get the word list, but either way you're going to have to do a little guesswork much like the Jumble daily challenges.

Once you unlock the bonus Jumble, just find the word to earn that star first, and the achievement will unlock immediately.
