4. Try and Aim for the Three Star Rating As Much As Possible
- Mastering any level requires completing the objectives that are asked of you on the current level you’re playing.
- Not only will you get some extra gold and loot in the form of cards, you’ll be awarded more XP as you tackle a level three times.
- Try to get as many three star rating on each stage, since you’ll get a free gem for doing so.
