Guide by LevelWalks
Brain Test: Tricky Puzzles Level 198 sits about 66% through the game's 300-level run — late enough that the obvious patterns no longer work, early enough that the mechanics still favor lateral thinking.
## Question
**Brain Test Level 198:** Find the different duck
## Quick Solution
The solution to Brain Test Level 198 is audio-based: **one duck quacks differently when tapped**. Turn up your phone volume, tap each duck, and listen — the odd one out has a unique sound.
## Step-by-Step Walkthrough
Rows of identical-looking ducks are displayed. Tap each one individually — they all quack, but one has a slightly different pitch or sound. That's the different duck.
Here is exactly how to solve Brain Test Level 198:
1. Read the question carefully — Brain Test loves wordplay and misdirection.
2. Look at every element on screen, including the question text itself.
3. Tap each duck one by one and listen carefully — one has a unique quack sound.
4. If you are stuck, remember that Brain Test rewards lateral thinking over logical answers.

## Why It's Tricky
Visual search dominance means you scrutinize appearances while ignoring audio. Brain Test uses sound as a differentiating feature here, and players with their phone on mute will never solve it. The puzzle tests multi-sensory attention.
## Why This Level Is Tricky
Difficulty 4 puzzles in Brain Test often involve meta-awareness — the solution might require interacting with your phone's hardware (volume buttons, tilt sensor) or manipulating the game's UI elements. The puzzle boundary extends beyond the screen content to include the device itself. 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 198:
- Overthinking a simple puzzle — sometimes the answer is literally what the question says, with no trick at all.
- Not trying to drag or resize on-screen elements, including text, images, and answer options.
- Missing that Brain Test sometimes reuses a trick from an earlier level with a slight variation.
Tips
- Look at negative space, shadows, and object arrangements for hidden patterns.
- The question text and UI elements are part of the puzzle — don't treat them as decoration.
- Remember: Brain Test Level 198 has a difficulty rating of 4/5 — it requires advanced lateral thinking.
Progressive Hints
Try each hint in order. Expand only as much as you need — stop before the spoiler if you want to solve it yourself.
Hint 1(small nudge)
Visual inspection alone won't crack this one — all the ducks look identical on screen. Think about what else your phone can detect besides touch.
Hint 2(warmer)
Turn your phone's volume up before you continue. Each duck responds when you tap it — pay attention to what you hear, not just what you see.
Hint 3(near answer)
Tap each duck one at a time and listen. One duck has a different pitch or quack sound from the others — that's the odd one out.
