Brain Out 2 Level 137
📝 Walkthrough
Overview
Level 137 says "so hot! Find a way to help her relieve heat!" A girl lies on a round rug fanning herself miserably with a book beside her. A standing fan sits nearby, but its power cable ends in a loose plug on the floor with nothing to plug it into. The victory line, "saved", appears once the fan starts blowing.
- Difficulty: Regular
- Estimated moves: 1
Step-by-Step Solution
- See her suffering. The girl is overheated and uncomfortable on the floor.
- Notice the fan. There is a fan, but its cord is unplugged and there is no wall outlet to use.
- Power the fan with a portable battery. Connect a power bank to the fan's USB cord.
- The fan starts. Once powered, the fan spins and blows a stream of air (wind lines visible).
- Confirm. The cool breeze makes the girl smile and relax. The screen says "saved" and the level is cleared.
Strategy & Reasoning
This is a power puzzle. The obvious solution — a fan is right there — fails because the fan has no electricity source. The wall switch panel is for lights, and there is no power socket by the fan.
The trick is to use a portable power bank to run the fan. Because the fan is USB-powered, a battery bank can supply it without a wall outlet. Once the fan is running, the airflow cools the girl down.
The window and curtain are decoration; opening them would not help on a still, hot day. The lesson is to think about how the fan actually gets its power — a battery bank when there is no outlet.
Tips & Common Mistakes
- Mistake: switching on the wall panel. That controls lights, not the fan.
- Mistake: opening the window. It does not create a breeze.
- Mistake: ignoring the unplugged cord. Connect a portable power bank to the fan's USB plug. Once it spins, she is cooled down.

Walkthrough Notes
The fan has no outlet to plug into. The power bank on the scene supplies it via USB; once powered, the fan blows and cools her. The victory line "Happy playing with water" style relief confirms it. Compare this with the wall light switch: that is for lights. The fan is USB-powered, so a battery bank runs it.
Why It Works
The fan is unplugged and there is no outlet on the wall. The wall switch controls the room light, not the fan. Because the fan is USB-powered, a portable power bank can run it. Once the battery is connected, the fan blows and cools the overheated girl. The curtain and window do not help because the air is still. The insight is that modern USB devices can run on batteries when no wall socket exists.
Handy Reminder
If the fan still will not spin, check that the power bank is actually connected to the fan's USB cable. The cable must be plugged in, not merely lying nearby.
