Strategy guide

- 3.Test combinations by dragging shapes that could form valid chemical equations together.
Common mistakes
- 1.Randomly dragging shapes without considering the alchemical symbols' meanings;
- 2.Placing shapes based on visual similarity rather than logical chemical equations;
- 3.Ignoring the puzzle's alchemy theme and treating it as a simple shape-matching task.
