Brain Test Level 390 Walkthrough: Lower the Temperature of the Refrigerator

Brain Test Level 390 Walkthrough: Lower the Temperature of the Refrigerator
Complete Solution, Step-by-step Guide, Common Mistakes
🧩 Level Information
- Level Number: 390
- Task: Swipe to the right of the refrigerator. Swipe the thermometer that appears downward to lower the temperature.
- Difficulty: Normal
🎯 Objective
Lower the refrigerator's temperature sufficiently to clear the puzzle.
📝 Solution Steps
- Check the refrigerator located near the center of the screen.
- Place your finger on the open screen area on the "right side" of the refrigerator, not on the refrigerator itself.
- Swipe from "right to left" on the right side of the refrigerator (swiping right will reveal the hidden thermometer).
- Instead of tapping the appeared thermometer to select, swipe the thermometer itself downward.
- Confirm that the scale of the thermometer is decreasing and the refrigerator's temperature is lowering.
- Once sufficiently lowered, it will automatically be recognized as cleared, and the stage is cleared.
💡 Hints
- Nothing happens if you tap the refrigerator itself. Try operating the surrounding blank area well.
- Swiping the screen to the 'right side' of the refrigerator may reveal hidden objects.
- The thermometer that appears is not a button. Try dragging or swiping it.
- The refrigerator's temperature decreases by 'lowering' the thermometer, not raising it. Swipe downward.
🧠 Analysis & Key Points
This stage tests a common Brain Test concept of 'drawing out objects from off-screen'. Initially, players tend to tap or try to open the refrigerator directly, but the correct answer is to swipe the blank area on the right side of the refrigerator to reveal the hidden thermometer. Furthermore, temperature adjustment requires an intuitive gesture operation of swiping the entire thermometer downward, not by pressing the buttons or +/- signs. While not visually complex, identifying the point of 'calling out unseen UI by swiping' is key.
🔍 Common Mistakes
- Repeatedly tapping the refrigerator body or trying to pry open the door by long pressing.
- Swiping only the 'left side' or top/bottom of the refrigerator, not trying the right side.
- After the thermometer appears, simply tapping and waiting for a response, not trying to swipe or drag.
- Accidentally swiping the thermometer upward, trying to increase the temperature instead.
- Trying to cool the refrigerator with other items in the level (if any), overlooking the important thermometer.
🎉 Post-Clear Advice
Successfully lowered the refrigerator's temperature and cleared the stage. You should have grasped the idea of calling out devices hidden off-screen. In the next level, pay attention to mechanisms involving swiping or dragging unseen places.
