Brain Test Level 239 Walkthrough & Answer
Level 239★★★★★
Guide by LevelWalks
Brain Test: Tricky Puzzles Level 239 sits about 80% 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 239:** Bring the temperature down to freezing
## Answer
Drag the thermometer's mercury/red line down to 0C/32F by swiping down on it.
## Step-by-Step Walkthrough
A thermometer shows a high temperature. Directly swipe down on the red mercury column to push it to the 0-degree mark. The thermometer is interactive — treat it as a slider.
Here is exactly how to solve Brain Test Level 239:
1. Read the question carefully — Brain Test loves wordplay and misdirection.
2. Look at every element on screen, including the question text itself.
3. Swipe down on the thermometer's red mercury column to lower it to the freezing point (0C).
4. If you are stuck, remember that Brain Test rewards lateral thinking over logical answers.
## Why It's Tricky
Display-as-read-only bias means you view the thermometer as showing information, not accepting input. Brain Test makes instruments interactive — you can SET the temperature, not just read it. This blurs the line between measurement and control.
## Why This Level Is Tricky
For difficulty 4, expand your toolkit: try shaking the device, using the volume rocker, covering the camera, or pressing the home button area. Also try dragging seemingly static elements like the level number, score display, or hint button. Brain Test treats everything on screen as a potential puzzle piece at this tier. 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 239:
- Reading the question too fast and missing a critical word like 'not', 'biggest', or 'smallest'.
- Assuming numbers on screen represent their face value when they might be Roman numerals, binary, or visual patterns.
- Skipping the hint system entirely — hints in Brain Test are progressive and often nudge without spoiling.
Tips
- Consider different number systems: Roman numerals, binary, or bases other than 10.
- Don't trust your first arithmetic instinct — Brain Test loves number misdirection.
- Remember: Brain Test Level 239 has a difficulty rating of 4/5 — it requires advanced lateral thinking.
