Tips for Hunting Achievements
- Finish the four starting campaigns first. They are the most-unlocked achievements, and each gold room mixes the mechanics of two of those worlds.
- Use the walkthroughs for the gold rooms. Each gold room combines the mechanics of two worlds. Start with the HxM Gold Room, the most-opened one so far.
- Use the Puzzle Finder to jump straight to the puzzle you are stuck on.
