Guide by LevelWalks
By Level 166 of Brain Test: Tricky Puzzles, you've already cleared 165 puzzles, which is exactly the moment the design starts to use that confidence against you. This one is built for players who've stopped reading the question carefully.
## Question
**Brain Test Level 166:** Which glass has more water?
## Answer
Remove the objects submerged in each glass first. The glass with the most water AFTER removing objects is the answer.
## Step-by-Step Walkthrough
Two glasses appear to have the same water level, but one contains a large rock displacing water. Drag the rock out of that glass. The water level drops, revealing it had less water. The other glass had more actual water.
Here is exactly how to solve Brain Test Level 166:
1. Read the question carefully — Brain Test loves wordplay and misdirection.
2. Look at every element on screen, including the question text itself.
3. Drag out any submerged objects first — they displace water and create a false impression of volume.
4. If you are stuck, remember that Brain Test rewards lateral thinking over logical answers.
## Why It's Tricky
Displacement ignorance is the physics concept Brain Test exploits. We judge water by surface level, not actual volume. Removing submerged objects reveals the true water quantity — a concept from Archimedes, applied to a phone puzzle.
## Why This Level Is Tricky
You're in the advanced zone now. These levels frustrate even veteran Brain Test players, so getting stuck is completely normal. The key insight for difficulty 4 is that the answer often involves doing something the game hasn't explicitly asked you to do. Think about what's possible, not just what's prompted. Late-game levels (151-300) frequently require device interaction — tilting your phone, using multiple fingers, shaking the device, or manipulating screen elements outside the puzzle area. Think beyond the touchscreen for these multi-step solutions.
## Common Mistakes
Players frequently make these errors on Level 166:
- Applying real-world logic to a puzzle that rewards absurd lateral thinking.
- Overlooking small UI elements like the level counter, hint button, or settings icon, which sometimes play a role in the solution.
- Assuming the puzzle has only one interactive element when multiple objects might need to be combined.
Tips
- Scroll or drag the screen to check for hidden elements beyond the visible area.
- The question text and UI elements are part of the puzzle — don't treat them as decoration.
- Remember: Brain Test Level 166 has a difficulty rating of 4/5 — it requires advanced lateral thinking.
