Each Jumble Adventure map level has three objectives to complete, and completing each one rewards you with a star. This achievement is cumulative across all Jumble adventure maps, so you can change maps as needed to unlock 100 stars.

The adventure mode levels are pretty simple, you essentially just need to find all of the anagrams. If you're struggling with this, feel free to use an anagram solver if you ever get stuck. You could also just move on to the next level as long as you unlock at least one star. There's no need to struggle with any difficult words, since you only need to earn 100 stars total and then you're done with Jumble adventure mode.

Once you reach 100 stars, the achievement will unlock.
