Tips for Solving Puzzles Faster
Before looking up a solution, it’s worth trying a few things on your own. The Mermaid Mask does a great job of hiding clues throughout the environment, and many puzzles become much easier once you’ve explored the surrounding room.
A few tips that can save you time:
- Talk to Grimoire and Sally regularly, as they often provide helpful hints.
- Read every note and item description you find.
- Examine rooms carefully before assuming a puzzle has no clues.
- Some puzzles intentionally require experimentation, so don’t be afraid to test different combinations.
- If a puzzle seems impossible, you may be missing an item or clue from another area.
The puzzles in The Mermaid Mask are one of the game’s biggest strengths. They range from simple observation challenges to more complex logic puzzles that reward careful exploration and attention to detail. While a few of them can be tricky, every solution brings you one step closer to uncovering the mystery behind the story.
If you’re aiming to complete the game without spending hours stuck on a single puzzle, this walkthrough should help you get back to exploring while avoiding unnecessary frustration.
