Brain Test Level 20 Walkthrough & Answer
Level 20★★★★★
Guide by LevelWalks
When I ran through Brain Test: Tricky Puzzles myself, Level 20 was one of the puzzles where I had to put the phone down and think for longer than I wanted to admit. The walkthrough below is what I worked out, plus the reason the trick works.
## Question
**Brain Test Level 20:** Which glass has the most water?
## Answer
Remove objects from the glasses first. The glass with objects displacing the most water actually has less water.
## Step-by-Step Walkthrough
Some glasses have objects submerged in them, making the water level appear higher. Remove all objects from the glasses — the one that still has the highest water level has the most actual water.
Here is exactly how to solve Brain Test Level 20:
1. Read the question carefully — Brain Test loves wordplay and misdirection.
2. Look at every element on screen, including the question text itself.
3. Remove objects from the glasses first.
4. If you are stuck, remember that Brain Test rewards lateral thinking over logical answers.
## Why It's Tricky
Brain Test Level 20 is designed to catch players who think too literally or too logically. The game's core mechanic is to subvert expectations. Most players fail this level on their first try because they approach it with conventional thinking. The key insight is that the game often uses the question text, physical phone gestures, or visual misdirection as part of the puzzle. Once you understand that Brain Test breaks the fourth wall regularly, these puzzles become much more manageable.
## Why This Level Is Tricky
Approach this level with a checklist: (1) read every word in the question, (2) tap each on-screen element individually, (3) try dragging objects around, (4) consider if the question text itself is part of the answer. Early Brain Test levels teach these four habits that carry through the entire game. These early levels (1-50) teach you Brain Test's fundamental trick vocabulary: literal wordplay, tapping hidden elements, and questioning obvious answers. Master these patterns now — they recur throughout the entire game.
## Common Mistakes
Players frequently make these errors on Level 20:
- Tapping the most obvious on-screen element without reading the full question first.
- Ignoring the question text as a potential interactive element — in Brain Test, words on screen can often be dragged, tapped, or used as part of the solution.
- Giving up too quickly instead of experimenting with device gestures like tilting, shaking, or using multiple fingers.
Tips
- Try dragging objects around the screen — many Brain Test puzzles require you to move elements to unexpected places.
- If your first instinct doesn't work, try the opposite approach — Brain Test loves to subvert expectations.
- Remember: Brain Test Level 20 has a difficulty rating of 1/5 — it should be solvable with a simple trick.
